SOURCE: Miss Code Ann. §41-67-3 Rule 5.5.18. Distribution of Effluent [Chamber Systems] 1.

When a change in elevation of the chamber system is required, a distribution box, connecting lateral or crossover must be used. At the point where a crossover line leaves a lateral, the trench for the crossover line shall be dug no deeper than the top of the endplate inlet or the inlet in the top of the chamber in the preceding trench so that an undisturbed block of earth will remain in place for the full depth of the system. The invert of the crossover must be at least four inches lower than the invert of the septic tank outlet line.

Distribution boxes may be used to connect the effluent line to the effluent distribution lines. The distribution box shall be level and supply all lines equally. Field lines (chambers) must be equal lengths when served by one distribution box. Non-perforated rigid pipe shall exit the distribution box for a minimum of five feet at level grade before the effluent distribution line begins.

Chamber systems installed in a trench configuration shall be sized in accordance with Table VIII.

Chamber systems installed in a bed configuration shall have the same number of chamber sections as indicated for a trench system. The length and width of the bed to be constructed will depend on the number of

127

chamber sections to be installed as indicated by Table VIII. Any side-byside placement of chambers shall constitute a bed. a.

Absorption beds and trenches should be located a minimum of 10 feet from any trees.

The bottom of the bed should have a relatively level grade; the grade within the bed shall not exceed the grade allowed for trench installations.

The chambers shall be placed side by side in a bed with separation between each chamber row per individual manufacturer’s requirements.

Care should be taken to prevent heavy machinery from damaging the bed during backfilling.

The effluent must be equally distributed to the bed by means of a distribution box or with a pipe manifold.

SOURCE: Miss Code Ann. §41-67-3 Subchapter 6. SUBSURFACE DRIP IRRIGATION 137

Rule 5.6.1. Subsurface Drip Irrigation is a system that utilizes 3 basic design principles. They are (1) uniform distribution of effluent, (2) dosing and resting cycles and (3) shallow placement of tubing. This system uses small diameter pipe with emitters and must be preceded by a treatment system that conforms to the manufacturer's specifications particular to that system. The effluent must be adequately filtered before distribution to the disposal field(s). Only Subsurface Drip Irrigation Systems that provide for timed dosing are acceptable. The term manufacturer, unless otherwise specified, is considered the manufacturer of the treatment device. (Figure I) SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.2. Definitions 1.

Advanced Treatment System – an Individual On-site Wastewater treatment system that complies with Section 41-67-10. Miss Code of 1972, Annotated 41-67-2(a)

Components – all physical, mechanical, and electrical components of any wastewater disposal system.

Distribution manifold – pvc pipe that delivers the treated effluent to the drip tubing.

Emitter – small labyrinth inside of drip tubing that eliminates pressure and releases drops of treated effluent.

Maintenance – the inspecting and evaluating of an Alternative System or Advanced Treatment System. The replacement of any component registered with a specific Advanced Treatment System (i.e., aerator, diffuser, control panel, etc.).

Subsurface Drip Irrigation System – a system that relies on advanced treatment and filtration of the treated effluent. Final disposal occurs in the upper limits of the soil horizon and is distributed through small diameter tubes that have emitters that slowly drip the treated water into the soil.

Tubing – a small diameter line made of a material that forms a tube which contains emitter and manufacturer’s fittings.

Vacuum breakers/air release valve – relieves pressure off the treated effluent and allows air to escape the system without causing damage.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.3. Design: Utilizing USDA soil groups as classified by textures is the most appropriate criteria on which to base loading rates for this system. The size of the disposal field shall be based on the most restrictive soil, naturally 138

occurring within 2 feet of the ground surface or to a depth of 1 foot below the trench bottom, whichever is deeper. Criteria and techniques for soil and site evaluation can be found in Chapter 03 Regulation Governing Residential On-site Wastewater Disposal Systems: Soil and Site Evaluation. 1.

Prior to the design of the Subsurface Drip Irrigation System, the suitability of the site must be demonstrated through acceptable soil permeability rates, acceptable soil conditions (Table I) and other topographic characteristics. The design and construction of the Subsurface Drip Irrigation System must conform to the drip tubing manufacturer's specification (Figure 1).

A minimum of 6 inches of naturally occurring soil must be present above a restrictive horizon or a predominantly gray soil (>50%) before placement of appropriate fill. Subsurface Irrigation System is not recommendable on hydric soils conditions.

Except where hydric soils are present, a clean fill material may be used to overcome seasonal water table limitation. The fill material shall consist of a minimum of 50 percent sand particles equal to or greater than 0.25 mm. Clay content shall be 20 percent or less. Organic matter shall be removed from the native soil surface prior to placing and incorporating the fill. This fill must be incorporated into the native soil to prevent a textural interface from developing. When fill material is used the entire fill area must be sodded to prevent erosion, or other effective erosion control methods used. The full depth of fill material must extend at least 2 feet in all directions from drip tubing and at that point shall be sloped at a grade of no steeper than 3 to 1.

In soils that contain a restrictive horizon, within 5 feet of the surface, there shall be a minimum of 12 inches of unsaturated soil between the bottom of the drip tubing and any perched or seasonal water table.

In soils that do not contain a restrictive horizon, within 5 feet of the surface, there shall be a minimum of 24 inches of unsaturated soil between the bottom of the drip tubing and any perched or seasonal water table.

Drip tubing must be installed a minimum of 6 inches deep. The maximum depth may not exceed 18 inches. In all cases there shall be a minimum of 12 inches separation between the water table and restrictive horizon.

Minimum separation between drip emitter shall be 2 feet. A 2 foot horizontal separation must be between drip tubing lines for slopes of less that 20 percent for slopes of 20 percent or greater shall be a minimum of 3 foot horizontal separation.

139

Drip tubing shall either be placed 4 inches lower than the supply manifolds or water breaks shall be used to prevent effluent from flowing along the drip tubing to the supply manifold trenches.

Valves, fittings, level control switches and all other components must be designed and manufactured to resist the corrosive effects of wastewater and common household chemicals.

Rule 5.6.10. Design Elevated Sand Mound Disposal System 1.

These guidelines present requisite site characteristics, design criteria, and construction techniques for on-site mound sewage systems. These guidelines provide a systematic approach to mound system design for typical domestic household wastewater. For systems serving other than single family dwellings the designer is cautioned that simple extrapolation of this information may not be appropriate.

When addressing wastewater flows that differ from a septic tank, such as those characterized by high biological oxygen demand (BOD5), total suspended solids (TSS), or oil and grease, the elevated sand-mound has inherent limitations. Wastewater from non-domestic sources should be evaluated on a case by case basis, to determine the amount of pretreatment necessary to apply to an elevated sand mound. The waste water applied to an elevated sand mound should not exceed 220 mg/l BOD5 or 145 mg/l TSS (no TSS particles should be retained on a 1/8th inch screen).

Mounds are an excellent treatment and disposal choice on appropriate sites, but they are not very forgiving. Special attention must be given to siting, design, pre-construction planning, site preparation, filter media selection, construction and maintenance of these systems. Quality control throughout the process cannot be overemphasized.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.11. General: 1.

Successful function of any on-site system is characterized by a two-fold process: treatment and disposal. The final treatment is accomplished predominately by physical and microbiological/chemical processes within the soil environment. These processes are affected by: a.

wastewater strength and characteristics,

soil moisture levels

the nature of the receiving soil, and

the soil loading rate.

Disposal is primarily affected by the depth of the unsaturated receiving soils, their hydraulic conductivity, and the area available for disbursement. The mound system relies on a single-pass flow pattern in unsaturated flow conditions through specified filter media (sand) for sewage treatment. The elevated sand-mound system incorporates the disposal component by discharging directly into the underlying soil.

153

A elevated sand-mound system is characterized by: a.

a pretreatment device ( a septic tank with an approved filter, or a treatment plant)

pressure distribution components ( pumping chamber, pump and controls, and distribution laterals.), and

the “mound” (fig. 1). The “mound” consists of: i.

filter media (sand),

ii.

an absorption area,

iii.

a distribution system, and

iv.

a soil cap and topsoil cover.

(Figure 1) 4.

A septic tank with an approved filter or a aerobic treatment unit may be used as the pretreatment for the elevated sand mound. The effluent, pumped from the pump chamber into the distribution network in the absorption bed area, flows through the filter media where it is treated through biological and chemical processes. The treated effluent then passes into the natural soil, that must have at least six (6) inches of unsaturated soil.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.12. Pre-Treatment: The preliminary treatment for an elevated sand-mound will be either an aerobic treatment unit or a septic tank with an approved filter. The pre-treatment method selected shall comply with the applicable sections of the Regulation Governing Individual Disposal. SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.13. Pumping Chambers: 1.

The pumping chamber shall have a minimum capacity of 750 gallons or twice the daily flow, whichever is the largest.

The pumping chamber shall be equipped with an audible and/or visual high water alarm.

The high water alarm must be set to allow a reserve capacity of 50% in the chamber when activated.

154

The pumping chamber shall have a grade level access large enough to allow servicing and/or removal of the largest component in the chamber. Access ports shall be protected against unauthorized entrance or removal.

The pumping chamber shall be vented through the grade level access or by means of a separate vent. In either case, the vent shall be equal to or greater than two times the diameter of the inlet port of the pump.

The pumping chamber shall be made of material resistant to the corrosive effects of wastewater and designed to withstand the lateral and bearing loads to which it is subjected.

All openings shall be sealed with a mastic, butyl rubber, or other pliable sealant that is waterproof, corrosive resistant and approved for use in contact with wastewater, in a manner to prevent the entrance of surface and groundwater.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.14. Minimum Pump Specifications: 1.

Although timed dosed systems are preferred, an elevated sand mound may utilize either a timed dosed or on-demand dosing cycles. Each dose volume shall not exceed the estimated maximum daily flow divided by the number of dosing cycles.

The pump selected must be able to fully charge the distribution system without hydraulically overloading the absorption area.

The pump shall be constructed of corrosion resistant materials suitable for effluent pumping.

The pump shall be equipped with a low water cutoff to prevent damage to the pump during low water conditions.

The pump shall be sized per manufacturers’ specifications to meet or exceed the hydraulic head of the system.

The pump shall be installed in compliance with the manufacturers’ specifications so as not to violate pump warranty.

The suction and pressure lines shall be schedule 40 or equal and be sized to meet or exceed the hydraulic head of the system.

SOURCE: Miss Code Ann. §41-67-3

155

Rule 5.6.15. Distribution System Specifications: 1.

The distribution system in an elevated sand mound shall consists of three components: a.

a pressurized distribution manifold- that shall consist of a small diameter (1"- 1.5") schedule 40 pipe, to receive the effluent from the pump. This pipe shall be connected as to not create any dead ends, and shall have 3/8" holes drilled in it every 36" pointing up. See Figures 2 and 3. The effluent from the pump must come to the center of this distribution manifold and absorption area.

field drain pipe to house the pressurized distribution manifold- A 4" field line pipe with the holes pointing down is acceptable. Other field drain pipe designs may be acceptable, but first must go through the experimental protocol.

distribution media- ½" to 2.5" gravel to a depth of 1' is acceptable. The design of the absorption area must comply with design guidelines for gravel underground absorption. If other distribution media is approved, they must comply with the appropriate regulations and guidelines.

Figure 3: TOP VIEW OF ABSORPTION AREA WITH DISTRIBUTION NETWORK AND FIELD LINE PIPE.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.16. Site Requirements for Elevated Sand Mounds: It is not possible to outline every conceivable soil, site or design situation which may occur. The following section addresses basic criteria that every elevated sand-mound will need to follow. 1.

Site conditions where elevated sand mounds are applicable: a.

Permeable soils with high water tables: The elevated sand mound is useful in many difficult soils and can be effective in overcoming high water tables. In fact, the use of an elevated sand mound on permeable soils with high water tables may be the most practical use of this system. Whether the water table is seasonal or permanent, these soils have inadequate vertical separation to provide satisfactory treatment with conventional systems. The mound system addresses these conditions by elevating the absorption area to achieve the needed vertical separation. Passing

156

the effluent through the filter media will result in a more thoroughly treated effluent, before it reaches the water table.

Slowly permeable soils: The elevated sand mound has an application on these soils, although may be costly due to the size of the basal area required. The elevated sand mound applies the effluent to the lighter textured top soil over a large area moving laterally until it is absorbed into the less permeable subsoil. On slowly permeable soils with high water tables, 5:1 side slopes are recommended.

Excessively permeable soils: These sites present the risk of inadequate wastewater treatment before it reaches unprotected aquifers. The elevated sand-mound system treats the wastewater to a higher level before it reaches the excessively permeable sub-soil.

Slope limitations with elevated sand mounds: Slope limitations for elevated sand-mounds are more restrictive than for conventional systems, particularly for mounds used on sites with slowly permeable soils. Elevated sand-mounds should not be considered on sites with slowly permeable soils and slopes of 6% or steeper. Elevated sand-mounds should not be considered on sites with permeable soils and slopes of 12% or greater. Figures 4 and 5 show how to place an elevated sand-mound on a flat and sloping site. a.

Figure 4

Figure 5

Minimum soil depth requirements - This is probably the most important factor determining how well the elevated sand-mound will function. If the soil has a restrictive horizon, the seasonal water table may not be any closer than 6 inches from the surface. If the soil does not have a restrictive horizon, the seasonal water table may not be any closer than 12 inches from the surface. If the restrictive horizon is not well defined, 12" of unsaturated soil is required. In all cases, there shall be a minimum of a 24" separation between the bottom of the absorption area and the water table.

Topography-Slopes - On permeable soils the maximum slope for the elevated sand mound is 12%. On slowly permeable soils (light clay loam or heavier) the maximum allowable slope for the elevated sand-mound is 6%. A crest of a slope is preferred because the elevated sand-mound can be situated to allow flow in both directions away from the filled area. It is certainly preferred that the design allows for the effluent to flow away from the elevated sand mound.

Level sites-Design should allow the effluent to flow in every direction away from the elevated sand-mound. On level sites with slowly permeable 157

soils, effluent may have a tendency to stack under the absorption area that may result in surface seepage around the base of the mound. The elevated sand-mounds should be placed in areas that allow the effluent to flow away from the filled area. 6.

Setback requirements- The set back requirements on Table 1 will be from the perimeter of the basal area, although no part of the system shall extend fully to a property line. The edge of the side slope must be at least 3 feet from a property line. a.

Table 1: Setbacks

Reserve area- An area must be set aside to replace the elevated sand mound in the case of failure. Due to the nature of a mound failure the following criteria must be met: a.

the area must be large enough to replace the entire system in a new untouched area.

the area must meet all the initial requirements of the original mound system, including but not limited to soil conditions, water table restrictions and setback requirements.

the area must not be used by property owner in a way which would adversely affect the placement of a new elevated sand mound system.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.17. System Design: 1.

A soil and site evaluation must be performed on the lot. See also Section VII. The loading rate of the natural soil must be determined from Table 2: a.

Table 2: Soil loading rates

Determine the average daily flow from the residence: Number of bedrooms X 130 gallons per day

Determining the size of the absorption area, basal area, side slopes, and maximizing length requirements: a.

Sizing the absorption area – The absorption area size shall be determined by the loading rate of the fill material. The fill material shall be coarse sand, 0.5-1.0 mm (USDA designation), and is the same as concrete sand (Section S-703, MS Standard Specification for State Aid road and bridge construction). The loading rate of this material is 1.2 gallons per day per square foot. Note: A fill 158

material as heavy as a light loam may be used, but this will change the size of the absorption area size. Use the appropriate loading rate of the fill to calculate the absorption area.

Example: Three (3) bedroom home @ 390 gallons per day

ii.

390 gallons per day / 1.2 gallons per day per square foot = 325 square feet

iii.

Absorption area = 325 square feet

Sizing the basal area: Using the information gathered from the soil and site evaluation, determine the loading rate of the natural soil within two (2) feet of the surface. Use the heaviest textured soil loading rate to size the basal area. Divide the average daily flow from the residence by the loading rate of the natural soil. i.

Example: Three (3) bedroom home @ 390 gallons per day a natural soil of a heavy loam

ii.

390 gallons per day /0.45 gallons per day per square foot = 867 square feet basal area

Maximizing length of the elevated sand mound: To the greatest extent possible, the elevated sand mound should be as long as possible. The length of the basal area and absorption area must always be at least 4 times the width. However, the width of the absorption area shall never be less than 2 feet.

Filter media depth: There shall be a vertical separation between the seasonal water table and the bottom of the absorption area of at least 2 feet in every situation. This separation may include up to 12 inches of unsaturated natural soil.

Calculation of side slopes: Side slope requirements will be different on level sites than on sloping sites. The side slope on the downhill side must be longer than the side slope going up hill. The following chart gives the correction factor on various slope conditions:

(Table 3: Correction factors) i.

Example: Given: 3' high mound with 9' side slopes placed on a 6% slope.

ii.

Table 3: Correction factors

iii.

Upslope side slope: 9' X .85 = 7.65' side slope 159

iv.

Downslope side slope: 9' X 1.22 = 10.98' side slope

1. All components of the elevated sand mound system shall be located a minimum of: c.

Five feet from any dwelling.

Ten feet from any property line.

The aerobic treatment plant, septic tank, and pump chamber shall be located a minimum of 50 feet from any public, private or individual potable water source.

The elevated sand mound shall be located at a lower elevation and a minimum of 100' from any public, private, or individual potable water source.

Potable water lines shall not pass under or through any part of the elevated sand mound system. Where a water supply line must cross a sewer line, the bottom of the water service within ten feet of the point of crossing, shall be at least 12" above the top of the sewer line. The sewer line shall be of Schedule 40 pipe with cemented joints at least ten feet on either side of the crossing. Water and sewer lines shall not be laid in the same trench. The water and sewer lines shall maintain a minimum separation distance of ten feet.

The area for the mound or the replacement area shall not be used for vehicular traffic or vehicular parking.

Aerobic treatment plants, septic tanks, pumping chambers or disposal system shall not be placed under a dwelling or other permanent structure.

Elevated sand mounds shall not be located in depressed areas where surface water will accumulate. Provisions shall be made to minimize the flow of surface water over the disposal system area.

Elevated sand mounds located on slopes of less than eight percent shall have a minimum setback from recreational waters, shellfish waters or other sensitive areas as prescribed in Table 4.

160

Elevated sand mounds located on slopes of greater than eight percent or greater shall be located a minimum of 100 feet from recreational waters, shellfish waters and other sensitive areas.

10.

Where all or part of the elevated sand mound is proposed to be installed on property other than the owner’s, an easement in perpetuity shall be legally recorded in the proper county. The easement shall be of sufficient area to permit access, construction and maintenance of the elevated sand mound.

11.

No site for an elevated sand mound or replacement area shall be located wholly within an area which is frequently flooded, swamp, marsh, or wetland. Except that if permits have been issued by the proper regulatory agency authorizing the use of wetlands for building sites and the installation of an individual onsite wastewater disposal system. The property shall be evaluated using standard soil and site criteria for IOWDS.

12.

When a proposed lot is located partially within a frequently flooded area, that portion of said lot not within the flood prone area may be considered for approval for the elevated sand mound.

13.

A minimum of 6 (six) inches of naturally occurring soil must be present above a restrictive horizon or a predominantly gray soil before placement of any fill.

14.

Easements or right-of-way areas for utilities, surface or subsurface drainage, roads, streets, ponds or lakes shall not be used as available space for an elevated sand mound.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.6.19. Construction 1.

Site Preparation: Good construction techniques are essential if the mound is to function properly. The following techniques should be considered: c.

Step 1: Rope off the site to prevent damage to the area during other construction activity on the lot. Vehicular traffic over the area should be prohibited to avoid soil compaction.

Step 2: Stake out the mound perimeter and bed in the proper orientation. Reference stakes set some distance from the mound perimeter are also required in case the corner stakes are disturbed.

Step 3: Cut and remove any excessive vegetation. Trees should be cut at ground surface and the stumps left in place.

161

Step 4: Measure the average ground elevation along the upslope edge of the bed to determine the bottom elevation of the bed.

Step 5: Install the delivery pipe from the dosing chamber to the center of the mound. Lay the pipe below the frost or slope it uniformly back to the dosing chamber so it may drain after dosing. Back fill and compact the soil around the pipe.

Step 6: Plow the area within the mound perimeter. Use a two bottom or larger moldboard plow, plowing 7 to 8 in. (18 to 20 cm) deep parallel to the contour. Single bottom plows should not be used, as the trace wheel runs in every furrow, compacting the soil. Each furrow should be thrown upslope. A chisel plow may be used in place of a moldboard plow. Roughening the surface with backhoe teeth may be satisfactory, especially in wooded sites with stumps. Rototilling is not recommended because of the damage it does to the soil structure. However, rototilling may be used in granular soils, such as sands. Plowing should not be done when the soil is too wet. Smearing and compaction of the soil will occur. If a sample of the soil taken from the plow depth forms a wire when rolled between the palms, the soil is too wet. If it crumbles, plowing may proceed.

Fill Placement c.

Step 1: Place the fill material on the upslope edges of the plowed area. Keep trucks off the plowed area. Minimize traffic on the downslope side.

Step 2: Move the fill material into place using a small track type tractor with a blade. Always keep a minimum of 6 in. of material beneath the tracks of the tractor to minimize compaction of the natural soil. The fill material should be worked in this manner until the height of the fill reaches the elevation of the top of the absorption bed.

Step 3: With the blade of the tractor, form the absorption bed. Hand level the bottom of the bed, checking it for the proper elevation. Shape the sides to the desired slope.

Distribution Network Placement c.

Step 1: Carefully place the coarse aggregate in the bed. Do not create ruts in the bottom of the bed. Level the aggregate to a minimum depth of 6 in. (15 cm).

Step 2: Assemble the distribution network on the aggregate. The manifold should be placed so it will drain between doses, either out 162

the laterals or back into the pump chamber. The laterals should be laid level.

Step 3: Place additional aggregate to a depth of at least 2 in. (5 cm) over the crown of the pipe.

Step 4: Place a suitable backfill barrier over the aggregate.

Covering c.

Step 1: Place finer textured soil material such as clay or silt loam over the top of the bed to a minimum depth of 6 in. (15 cm).

Step 2: Place 6 in. (15 cm) of good quality topsoil over the entire mound surface.

Step 3: Plant grass over the entire mound using grasses adapted to the area. Shrubs can be planted around the base and up the sideslopes. Shrubs should be somewhat moisture tolerant since the downslope perimeter may become moist during early spring and late fall. Plantings on top of the mound should be drought tolerant, as the upper portion of the mound can become dry during the summer.

Operation and Maintenance c.

Routine Maintenance: A properly designed and constructed mound should operate satisfactorily with virtually no regular maintenance.

Rehabilitation: Three failure conditions may occur within the mound. They are (1) severe clogging at the bottom of the absorption area, (2) severe clogging at the fill material and natural soil interface, and (3) plugging of the distribution network. Usually these failures can be easily corrected. i.

If severe clogging occurs at the bottom of the absorption bed, its cause should first be determined. If it is due to failure to maintain the pretreatment unit, hydrogen peroxide to oxidize the accumulated organics at the infiltrative surface could be used. The chemical can be applied directly to the bed or through the dosing chamber. Because of the danger in handling this strong oxidant, this treatment should be done by professionals.

ii.

If the clogging is due to overloading or unusual wastewater characteristics, efforts should be made to reduce the wastewater volume or strength. It may be necessary to 163

enlarge the mound. The mound cap should be removed and the aggregate in the absorption bed stripped out. The area downslope of the mound should be plowed and additional fill added to enlarge the mound to the proper size. The absorption bed can then be reconstructed. iii.

Severe clogging at the fill and natural soil interface will cause surface seepage at the base of the mound. This area should be permitted to dry and the downslope area plowed. Additional fill can then be added. If this does not correct the problem, the site may have to be abandoned.

iv.

Partial plugging of the distribution piping may be detected by extremely long dosing times. The ends of the distribution laterals should be exposed and the pump activated to flush out any solid material. If necessary, the pipe can be rodded.

Sizing of the spray disposal field will be based on the most restrictive soil within twelve (12) inches of the naturally occurring ground surface.

To overcome the lack of sufficient depth, to a restrictive horizon and/or Seasonal High Water Table, a clean fill material of a texture of sandy loam may be used as fill material. Organic matter shall be removed, from the native soil surface, prior to placing and incorporating the fill. This fill must be incorporated into the native soil to prevent a textural interface from developing. When fill material is used the entire fill area must be sodded to prevent erosion, or other effective erosion control methods used. The full depth of fill material must extend at least ten (10) feet in all directions from outer edge of the spray field and at that point shall be sloped at a grade of no steeper than 3 to 1 (Table II).

The non compliance of one or more of the above items may (1) require a design alteration or (2) prohibit the use of a Spray Irrigation Disposal system. Slopes of greater than sixteen (16) % may be considered on a case by case basis.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.7.3. Location of Spray Irrigation Disposal Systems: 1.

Non Waterborne Wastewater Systems

Rule 5.10.1. General. In remote areas of the State or certain transient or temporary locations, the use of non-waterborne systems such as sanitary pit privies, portable toilets, incinerating toilets, composting toilets, and related sewage disposal systems may be approved. Due to their limited capacities, these systems are restricted to receive excreta only. Since such systems require regular service and maintenance to prevent their malfunction and overflow, they shall only be used where the local health department approves such use. Typical locations of non-waterborne systems are rural camps, seasonal recreation areas, construction sites, public gatherings, and similar transient or temporary locations. 1.

Portable toilets may be approved by county health departments for temporary or transient locations where numbers of people congregate for periods of short duration for a specified length of time. A contract for maintenance shall be provided in writing to the county health department prior to approval.

Sanitary pit privy installation shall be permitted only in remote locations, but in no case shall such installation be permitted for buildings with indoor plumbing and where water under pressure is located in the structure. Construction of the pit privy will be in compliance with a.

FIGURE 1&2.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.10.2. Construction: 1.

There shall be maintained a minimum of two feet separation between the bottom of the privy vault and indicators of seasonal water (gray mottles).

The privy shall be a minimum of 100 feet, downgrade, from any potable water source.

The privy shall be located 100 feet from sensitive waters.

The privy shall be constructed to prevent surface water from running into the pit.

When the pit becomes filled to within sixteen inches of the ground surface, a new pit shall be excavated and the old pit shall be backfilled to the surface.

SOURCE: Miss Code Ann. §41-67-3 Rule 5.10.3. Registration: Manufacturers of non-waterborne toilets that incorporate mechanical or non-mechanical technology for the collection and/or treatment of human excreta must submit documentation to the Division of Sanitation verifying the performance of their product. Upon approval, these systems will be placed on an approved list of registered systems. 187

DISINFECTION

Rule 6.1.1. Introduction: The discharge of treated wastewater shall be disinfected when the effluent will be disposed of by means of a surface discharge (Overland Discharge or Spray Irrigation). Individual On-site Wastewater Disposal Systems that utilize surface discharge shall have an approved method of effluent disinfection prior to disposal. 189

The most common disinfect is chlorine. Other methods of wastewater disinfection are ultra-violet and ozone. SOURCE: Miss Code Ann. §41-67-3 Rule 6.1.2. Definitions: 1.

Advanced Treatment System (ATS) – An Individual On-site Wastewater Disposal System that treats and complies with Section 41-67-10. Section 41-67-2(a)

Chlorine – a highly irritating, greenish-yellow gaseous halogen, capable of combining with nearly all other elements, produced principally by electrolysis of sodium chloride and used widely to purify water, as a disinfectant and bleaching agent, and in the manufacture of many important compounds including chloroform and carbon tetrachloride.

Chlorinator – a device that allows the treated effluent to pass around and over calcium hypochlorite tablets or the treated effluent is dosed with a specific amount of liquid chlorine by the use of an approved dispersal method.

Chlorine Contact Chamber –chamber designed to provide a minimum of 1 hour detention time at the peak design flow.

Chlorine (liquid) – an aqueous solution of calcium hypochlorite used as a disinfection agent.

Chlorine (tablet) – a solid form of calcium hypochlorite, a common disinfectant. These tablets dissolve in the wastewater, releasing the hypochlorite, which then becomes hypochlorous acid, the primary disinfectant.

Chlorine Residual – free chlorine remaining after the chlorination process has occurred.

Disinfection – treatment to destroy harmful microorganisms and viruses.

Feeder Tube – a device which holds Chlorine tablets in place in order to contact effluent.

10.

Ozone – an unstable, poisonous allotrope of oxygen, O3, which is formed naturally in the ozone layer from atmospheric oxygen by electric discharge or exposure to ultraviolet radiation, also produced in the lower atmosphere by the photochemical reaction of certain pollutants. It is a highly reactive oxidizing agent used to deodorize air, purify water, and treat industrial wastes.

11.

Pathogen – An agent that causes disease, especially living microorganisms such as bacteria, viruses, or fungus.

190

12.

Swimming Pool Chlorine – Chlorine made from Trichlorisocyanuric acid instead of calcium hypochlorite. These tablets are not acceptable for use in On-site systems. They do not dissolve as quickly as wastewater grade tablets and do not treat effluent as required. Also, if not continually immersed in water, these tablets can be explosive due to the release of nitrogen chloride gas.

13.

Ultra-violet disinfection – disinfection device that uses ultra-violet light source to eliminate or destroy bacteria, viruses and other pathogenic organisms.

14.

Ultra-violet light – radiation lying in the ultra-violet range; wave lengths shorter than light but longer than X-rays

SOURCE: Miss Code Ann. §41-67-3 Rule 6.1.3. Design: It is important that wastewater be adequately treated prior to disinfection. The effectiveness of a disinfection system depends on the characteristics of the wastewater, the amount of time the microorganisms are exposed to the disinfectant, and the chamber configuration. The design for each type of disinfection is as follows: 1.

Chlorine Tablet or Liquid a.

The Chlorine Contact Chamber must meet the following requirements: i.

Constructed from concrete, fiberglass or polyethylene in accordance with Appendix 01.

ii.

Constructed to withstand the earth pressures encountered and able to withstand the chemical effects of chlorine and wastewater.

iii.

Equipped with baffles or provided with an inlet to provide adequate mixing and contact of chlorine and effluent. The inlet and outlet must be Schedule 40 PVC pipe, 4 inches in diameter with the outlet tee extending 6 inches from the bottom of the chamber. (Figure I)

iv.

Designed and located to have access a minimum of 6 inched above final grade.

Provide 65 gallons (minimum) capacity or 1 hour retention. NOTE: If the chlorine contact chamber is an integral component part of the design of the Advanced Treatment System the efficiency shall be certified by the third party certifying entity.

vi.

Sealed (water-tight) to prevent the entry of surface or ground water. It is recommended that the outlet be placed above any seasonal water tables as indicated by gray mottles. An approved 191

sealant shall be applied to the lid, inlet, outlet and access opening to prevent groundwater and surface water intrusion.

vii.

Consideration will be given to 2 flow-through units with commonwall construction so that each side satisfies the detention requirements. The chlorine feed rate will be proportioned in accordance with the flow and the chlorine demand of the wastewater. Adequate mixing during the chlorine contact period will be insured by the installation of adequate baffling.

viii.

Pumped periodically for sludge accumulation and properly disposed.

The feeder tube and liquid chlorinator dosing compartment must meet the following requirements: i.

Installed level on undisturbed earth or backfilled with sand.

ii.

Charged with a minimum of 3 calcium hypochlorite chlorine tablets or the dosing compartment is 1/2 filled with liquid chlorine.

iii.

Equipped with a method for removal. The method of removal must be within 3 inches of the chlorinator opening.

iv.

Constructed of Schedule 40 PVC pipe, 3 inches in diameter and provide removal of all chlorine tablets when feeder tube is removed from chlorinator. (Figure II)

Childproof and Tamper resistant, or limited access cover.

Ultra-violet a.

The main components of a ultra-violet disinfection system are mercury arc lamps, a reactor, and ballasts. The source of the ultra-violet radiation is either the low-pressure or medium-pressure mercury arc lamp with low or high intensities.

The optimum wavelength to effectively inactivate microorganisms is in the range of 250 to 270 nm. Low-pressure lamps emit essentially monochromatic light at a wavelength of 253.7 nm. Standard lengths with diameter of 1.5 – 2.0 cm. The ideal lamp wall temperature is between 95 and 122ºF.

The effectiveness of a ultra-violet disinfection system depends on the characteristics of the wastewater, the intensity of the ultra-violet radiation, the amount of time the microorganisms are exposed to the radiation, and the reactor configuration.

192

All ultra-violet disinfection must provide a flow either parallel or perpendicular to the lamps and have a ballast or control box which provides a starting voltage for the lamps and maintains a continuous current.

There are two types of ultra-violet disinfection reactor configurations that exist:

Contact: This reactor contains a series of mercury lamps are enclosed in quartz sleeves to minimize the cooling effects of the wastewater. The lamps are placed parallel or perpendicular to the direction of the wastewater flow. Flap gates or weirs are used to control the level of the wastewater.

ii.

Noncontact: This reactor contains mercury lamps suspended outside the transparent conduit, which carries the wastewater to be disinfected.

The ultra-violet disinfection must provide the following: i.

Necessary hydraulic properties for maximize exposure to ultraviolet radiation.

ii.

Necessary intensity of ultra-violet radiation needed for effective inactivation of microorganisms.

iii.

Necessary radiation for peak flow condition, suspended or colloidal solids, initial bacterial density and any other physical and chemical parameters (i.e., hardness, iron, pH or TSS).

The ultra-violet disinfection system must ensure that sufficient radiation is transmitted to the organisms to render them sterile. All surfaces between the radiation and target organisms must be clean, and the ballast, lamps, and reactors must be functioning at peak efficiency.

The sleeves or tubes must be cleaned regularly by mechanical wipers, ultrasonics, or chemicals. The cleaning frequency is dependent upon the wastewater characteristics produced by the Advanced Treatment System.

The retention time for complete inactivation will be determined by size of reactor and lamp intensity.

All disinfection systems certified by American National Standards Institute/National Sanitation Foundation International Standard 46 will be accepted for registration in Mississippi provided documentation is submitted with application.

193

All disinfection systems not certified by American National Standards Institute/National Sanitation Foundation International Standard 46 must submit all documentation to determine compliance with 102.03 through 102.07.

Ozone a.

These products will be reviewed by the Division in accordance with design, construction and installation for the specific location and usage.

These products will only be approved by the Division after certification by a Professional Engineer registered in the State of Mississippi after having shown it can be constructed and installed by the Certified Installer.

This product will require that the Professional Engineer train and certify the Maintenance Provider in it routine operation and maintenance, as well as safety guidelines.

SOURCE: Miss Code Ann. §41-67-3 Rule 6.1.4. Location/Setbacks: 1.

The disinfection system shall not be located in an area that collects surface water.

The disinfection system shall be installed according to the following setbacks: a.

5 feet from foundations, deck, out-building, etc

10 feet from property lines

50 feet from any public, private or individual potable water source

No vehicular traffic shall be allowed over the tank(s), disinfection system or any part of the Individual On-site Wastewater disposal System.
