The use of community subsurface sewage disposal systems is prohibited unless the properties, dwellings, commercial units or other premises to be served by sewage disposal systems are constructed, designed and located in such a manner that the construction of individual sewage disposal systems in accordance with Article II of this chapter would be most impractical or impossible. Percolation tests must be performed on each proposed lot in the development before a community system may be considered. If a community system is proposed, double ring infiltrometer tests must be performed in the disposal area. In no event, however, shall construction of a community sewage disposal system be permitted in Class C soil or in a floodplain.
Permission to locate, construct or alter a community sewage disposal system must be sought from the administrative authority and may only be granted if facts are established to its satisfaction and assurances given that only one legal entity will be responsible for the maintenance, operation, repair and replacement of the system and that the system will meet the construction and design standards contained herein.
Required components of all community sewage disposal systems are as follows:
Community septic tanks. In addition to individual septic tanks located on the premises of each realty improvement, there shall be at least one large community septic tank for each alternating disposal field. The community septic tank shall be of shallow depth dual compartment regular reinforced concrete design and the size shall be the larger of either 5,000 gallons minimum or 1/3 the total estimated volume expected based on the table found in § 131-7. Said tanks shall be preceded by a selective diversion valve and interconnected with a gravity overflow device and equipped with auditory and visual level alarms in the event of malfunction of the active tank.
Sewage collection system. The conduit system which conveys the liquid portion of the sanitary sewage from the individual septic tank to the community septic tank.
Wet well with duplex pumping stations and pressure distribution system. The effluent of the community septic tanks will accumulate in a wet well, which will provide the volume necessary to dose the associated disposal field. The disposal field will receive the dose of effluent via a watertight force main manifold connected to a perforated distribution pipe. Auditory and visual alarms detectable on site and relayed to a central alarm company will be activated in the event of malfunction.
Alternating disposal fields. Each community septic tank shall have an associated alternating disposal field. Use of the alternating disposal fields shall be changed annually or as otherwise required by the administrative authority to permit one field to rest while the other is in use. (See Figure 1.)
Reserved disposal field area. In addition to the alternating disposal fields, each community sewage disposal system shall have an associated reserve area. This area shall have been tested in the same manner as the primary disposal fields. The reserve area shall have the capacity to accept as a minimum the same quantity of effluent as the disposal area for which it is in reserve.
No disposal field may be constructed unless the bottom of the disposal bed is at least four feet above the highest seasonal water table elevation, as determined by the approved professional and verified by the authorized agent. In no event will a disposal field be permitted to be constructed in a floodplain.
Monitoring wells. Monitoring wells shall be installed and shall extend from the bottom infiltrative surface of the system up to or above final grade. The bottom should be open and the top capped. The portion of the pipe within the gravel should be perforated to permit a free flow of water. Spacing and location of monitoring wells shall be at the discretion of the authorized agent.
Each realty improvement to be connected to a community sewage disposal system shall have its own septic tank, which shall be sized and constructed in accordance with Chapter BH:III, Subsections BH:3-4.22, BH:3-4.24 and BH:3-4.25 of the Individual Sewage Disposal System Code of West Windsor and located between the realty improvement and public right-of-way.
Flow restrictors and low-volume flush toilets are required.
The design of a community sewage disposal system shall take into consideration the location of the wells or other sources of water supply, topography, existing individual or community sewage disposal systems on adjacent properties, water tables, soil characteristics, available area and expected volume of sewage and shall comply with these and other provisions of this article regarding design. All engineering data submitted must bear a professional engineer's seal and signature. The engineer responsible for design shall also inspect construction and certify that the work has been constructed in accordance with the minimum requirements of the design. Alterations to community sewage disposal systems shall be certified by the authorized agent and be subject to approval by the administrative authority.
Each unit of the disposal system shall be designed to adequately treat the estimated volume of sanitary sewage to be discharged from the community to be served. The volume of sewage flow shall be based on the estimated contributory population and the resultant expected daily quantities of sewage, as determined from the following table:
The use of garbage grinder units by any realty improvement serviced by a community sewage disposal system is prohibited.
The minimum distances for location of the various component parts of a community sewage disposal system shall comply with the following table:
The disposal fields shall be posted and trespassing thereon prohibited. Access to disposal fields shall be strictly limited and trees shall be planted thereabout in a manner approved by the administrative authority to prevent vehicular traffic.
In subdivisions comprised of both lots on which individual sewage disposal systems (Article II) are to be constructed and lots which will be served by a community sewage disposal system, the disposal fields for a community sewage disposal system shall be sized to include the flow from any lot to be served by an individual system which is adjacent to or across the street from any lot to be served by the community system. In no event, however, shall any lot served by an individual system be connected to the community system until it has been demonstrated to the administrative authority that all steps to rebuild or rehabilitate the individual system have been taken and have failed.
Until title to all of the realty improvements to be serviced by the system has been transferred from the developer, including the developer's successors and assigns, to the respective owners who will be occupying the realty improvements, a community sewage disposal system shall be maintained, operated, repaired and replaced by the developer. Thereafter, a homeowners' association comprised of the owners of each realty improvement serviced by the system shall maintain, operate, repair and replace the system. A separate homeowners' association need not be formed for the sole purpose of maintaining, operating, repairing and replacing the system in the event that the owners of each realty improvement serviced by the systems are members of an open space organization formed pursuant to N.J.S.A. 40:55D-43 or a homeowners' association charged with other responsibilities. In the event that said homeowners' association is comprised of owners whose property is not serviced by the system, those owners whose property is not so serviced shall not be responsible for maintenance, operation, repairs and replacement of a community sewage disposal system. Said association shall not be dissolved or dispose of the system by sale or otherwise without the approval of the administrative authority.
The bylaws, membership assessments and dues and methods of enforcement and collection of delinquent assessments and dues of the homeowners' association insofar as they pertain to maintenance, operation, repair and replacement of a community sewage disposal system shall be submitted to and approved by the administrative authority at such time as application is made for a permit to locate, construct or alter a community sewage disposal system.
Declaration of covenants, conditions, restrictions and bylaws shall be recorded in the Mercer County Clerk's Office in the book for the recording of deeds, which recording shall be prior to the first conveyance of any realty improvement to be serviced by a community sewage disposal system.
The Township shall not be responsible for any dry sewer lines installed as part of major subdivision approval and used for the transfer or pumping of sewage to any community sewage disposal system. During the period of such use, the legal entity responsible for maintenance, operation, repair and replacement of the system under this section shall remain fully responsible for the system.
Pressure distribution systems are required for all community sewage disposal systems. Designs of these systems shall be in accordance with the EPA Design Manual for On Site Wastewater Treatment and Disposal Systems, Chapter 199, of N.J.A.C. 7:0.2.1 et seq., and Figure 1. In addition, the systems shall comply with the following standards:
Absorption area. The total absorption area required shall be computed from the daily wastewater flow and design loading rate. The required absorption area equals the wastewater flow divided by the design loading rate as below.
Design loading rate. The design loading rate for a site is based on the permeability, as determined by hydraulic conductivity tests, and the soil texture for the site of the pressure distribution system as follows:
Soil horizon. Pressure distribution systems will not be permitted in impervious formations unless the design calls for that horizon to be removed and replaced by specified material with a permeability more rapid than two centimeters per day and it is clearly demonstrated by permeability testing that the removal of such a layer would allow adequate hydraulic functioning.
Distance between filter stone and impervious formation. A minimum of four feet must be maintained between the bottom of the filter stone in the disposal bed and impervious formation or the highest seasonal high water table.
Discharge of effluent into trenches, beds, disposal fields or mounds. Pressure distribution systems shall discharge effluent into trenches, beds or disposal fields unless the level of the water table is such that trenches, beds or disposal fields may not be installed in accordance with these provisions, and, in that event, effluent may be discharged into mounds in accordance with section § 131-15. In no event, however, shall installation of a mound be permitted in Class C soils or a floodplain over a failing subsurface sewage disposal system or in a filled area (removal of the fill material does not cause the site to become suitable).
Distribution pipes. Each pipe that is connected to an outlet of a manifold shall be considered a separate distribution line. All distribution lines shall be installed at the same elevation or the plans and specifications shall provide for a design that ensures equal flow throughout the system. Distribution lines shall be connected to the manifold by tee's or 90 ells. The ends of distribution lines shall be capped.

Diameter of distribution line: Up to four inches.
Horizontal spacing of distribution lines: 30 inches to 72 inches.
The diameter of the distribution line may vary, depending upon the length of the trenches or mound.
Manifold and manifold line. The size of the manifold shall be based upon the number, length and discharge rate of the distribution lines. The manifold pipe delivers effluent from the pump to the distribution network. The manifold pipe shall be two inches to six inches in diameter and unperforated. The manifold shall be sloped toward the pump chamber to drain effluent back after dosing.
Dosing volume. The dosing volume shall be a minimum of 10 times the volume of the laterals, but shall not exceed the daily disposal capacity of the trenches or beds.
Dosing frequency. The dosing frequency shall be established by the administrative authority on the basis of soil conductivity, but in no event shall be less than two times per day or greater than four times per day.
Pressure to be maintained in distribution lines. Two feet of head shall be maintained in the pressure distribution system.
Friction loss. Friction loss for schedule 40 plastic pipe shall be computed on the basis of C = 150.
Total head loss through the distribution system. Total design head loss shall include an additional two feet of head. A system's head curve shall be included as part of the design calculations.
Pump manufacturer's model number, size and pump performance curve required. The pump manufacturer's model number, size and pump performance curve shall be supplied to the administrative authority.
High water alarm system and pump chamber control system.
The control system for the pump chamber shall consist of controls for operating the pumps and an alarm system to detect malfunctioning of a pump. Pump controls shall be capable of alternating operation of the pumps. Pump controls shall allow flexibility in adjusting the on/off depth.
The size of the pump chamber shall be determined by the number of realty improvements served and dosing frequency, but in no event shall it be less than 1,000 gallons. A standard septic tank may be used as a pump chamber. The pump chamber shall be watertight.
The use of pressure diaphragm switches in the pump chamber control system is prohibited and mercury level control switches are required. Adjustable weight switches consisting of a control located above the water level and two weights attached to a single cable which extends into the liquids are required.
The alarm system shall consist of a bell and light, which shall be located so that the same may immediately be seen or heard by the legal entity responsible under § 131-12 for maintenance, operation, repair and replacement of the system. The high water warning switch shall be installed two inches above the depth set for the "On" pump control. Alarm systems shall be installed on a separate circuit from the electrical service with battery-powered standby, which battery-powered standby shall be recharged by a battery charger connected to commercial power or the emergency generator referred to in Subsection P. Remote alarms are also required and shall terminate at a central alarm company via telephone lines maintained by the legal entity responsible under § 131-12 for maintenance, operation, repair and replacement of the system.

Buried full storage capacity for the emergency generator shall be sufficient to provide 12 hours of pump operation. The generator, electrical panel/electrical system, starting batteries and other generator controls shall be housed in a weatherproof enclosure.
Wash down water system. A nonpotable well shall be installed to provide a guaranteed continuous safe yield of 15 gallons per minute. The submersible well pump shall have a minimum capacity of 12 gallons per minute 25 psi with a single phase 11 5/230 motor. All water service piping shall be self-draining and freeze protected.
In addition to the requirements of § 131-13, the following standards shall apply to pressure distribution systems which discharge effluent into trenches, beds or disposal fields:
Aggregate. Aggregate shall be placed to a minimum depth of 18 inches beneath the distribution pipe and to the level of four inches above the pipe, spread evenly.
Inspection by authorized agent. The authorized agent shall inspect pressure distributions which discharge effluent into trenches, beds or disposal fields at commencement of the placing of the aggregate and while the distribution piping is being installed. A pressure test of the nonperforated sections of the system shall be performed in the presence of the authorized agent at the time of inspection.
In addition to the requirements of § 131-13, the following standards shall apply to pressure distribution systems which discharge effluent into mounds:
Depth to restrictive layers or bedrock. There shall be at least four feet of unsaturated natural soil over restrictive layers or bedrock. Mounds shall be constructed such that there is a minimum of four feet of unsaturated soil between the gravel envelope and impervious formations.
Depth to seasonally high groundwater. There shall be at least four feet of unsaturated natural soil over seasonally high groundwater as indicated by soil mottling. There shall be four feet of unsaturated soil beneath the gravel envelope of the mound system.
Slope of existing terrain.
A mound shall not be installed on a slope which is greater than 12%. (See Table 1 of § 131-15E.)
Location of mound on sloping sites. The mound shall be located so that the longest dimension of the mound and the distribution lines are perpendicular to the slope. The mound shall be placed upslope and not at the base of a slope. If there is a complex slope (two directions), the mound shall be situated so that the effluent is not concentrated in one direction. Surface water runoff shall be diverted around the mound.
Side slope for mounded systems. Side slopes for mounded systems must be no greater than a three-to-one slope (horizontal to vertical).
Design. Mound systems shall be designed in accordance with the EPA Design Manual for On Site Wastewater Treatment and Disposal Systems. The disposal area shall be designed using the following method for sizing:
Determine soil texture using USDA Classification.
Determine loading rate (GPD/feet).
Determine vertical hydraulic conductivity (centimeters/day) (feet below existing grade).
Determine depth to seasonally high water table.
Determine depth to bedrock or impermeable layers (feet).
Determine existing grade (% slope).
Determine design flow (GPD).
Determine size absorption area (feet2).
Fill material. The following types of fill material are required for construction of a mounded system:
Aggregate shall be 1 1/2 inches to two inches crushed stone or washed gravel. Limestone or dolomite shall not be utilized. The minimum thickness of the aggregate shall be four inches above and 18 inches below the laterals. The aggregate must not extend more than three feet outward beyond the limit of the laterals.
Filler sand shall meet the specifications for select fill and shall be emplaced below the aggregate.
Clay cap/barrier. A minimum of six inches of clay shall be employed for the entire clay cap of all mound systems. The administrative authority shall determine the appropriate thickness of the clay cap/barrier based upon the slope and particular edge of the mound on which it is being installed.
Topsoil. Topsoil shall be used to cover the mound to a depth not less than six inches, and this shall be planted with a variety of grasses.
To avoid smearing of native soils and the possibility of settlement after construction, site preparation must not be undertaken when the ground is wet or frozen.
The soil horizon upon which the select fill will be placed must be plowed or disced perpendicular to the slope to achieve a good transition zone between the filter material and the native soil and to discourage lateral migration of the percolating effluent at this interface.
Plowing shall be to a depth exceeding six inches, but not exceeding nine inches. Rototilling is prohibited.
Operation and maintenance. The pump chamber or siphon shall be kept free of excess solids. Vegetal cover shall be maintained intact on the mound and erosion prevented.
Where a system design other than that described in this article is proposed, the applicant must submit the design to the administrative authority and the Department concurrently. This proposal must be accompanied by a written statement justifying such a design, containing, as a minimum, the following information:
The Department of Environmental Protection and administration authority request additional information relative to the above. The Department and administrative authority shall approve or disapprove with regard to the technical adequacy of the proposal and its impact upon groundwaters and surface waters and shall notify the applicant.
Double ring infiltrometer test. Vertical hydraulic conductivity shall be determined by the double ring infiltrometer test as performed by an approved professional. When there are sufficient number of cobbles, stones, gravel, etc., in the soil so that the infiltrometer rings cannot be properly inserted, it will be necessary to perform other specific tests to determine the soil suitability. The use of such tests shall first be approved by the administrative authority or its authorized agent.
Required depth of permeability testing.
Slowly permeable soils with or without high groundwater. Permeability tests shall be conducted at a depth of 20 inches to 24 inches from existing grade. If a more slowly permeable horizon exists at less than 20 inches to 24 inches, permeability tests shall be conducted within that horizon which is the more or most restrictive.
Shallow permeable soils over creviced bedrock. Permeability tests shall be conducted at a depth of 12 inches to 18 inches from existing grade. If a more restrictive horizon exists within four feet, permeability tests shall be conducted within that horizon.
Permeable soils with high groundwater. Permeability tests shall be conducted at a depth of 20 inches to 24 inches from existing grade. If a more slowly permeable horizon exists at less than 20 inches to 24 inches, permeability tests shall be conducted within that horizon.
Determination of seasonably high water table and test pit requirements.
The level of seasonally high water table shall be determined by the highest level of soil mottles. This visual determination shall be made by an approved professional in accordance with the following requirements:
A minimum of four test pits shall be made for each proposed disposal area. All pits shall be at least 10 feet deep and one such pit shall be on each side but immediately outside the limits of the proposed disposal bed area. The face of each test pit shall be exposed to direct sunlight during the visual examination. The pits shall be dug within 72 hours of visual examination by the approved professional.
The approximate seasonal high water table location may be initially identified by inspection pipes or existing ponds or pits around the perimeter of the proposed disposal area or field examined during the wettest period of the year. Final determination of the seasonal high water table shall be made by an approved professional's visual and textural examinations of the full depth of the test pits. Specific attention shall be paid to the observation of low chroma mottles. The presence of gray mottles with a chroma of two or less is considered sufficient evidence of a seasonal high water table in most soils. In certain soils, three chroma mottles with values of six or seven are indicators of wetness. Relic mottles which do not represent wetness under current climate shall be identified, but will not be used to determine the level of the seasonal high water table.
Soils that are wet but do not have low chroma mottles shall be identified and are to be used in determination of the seasonal high water table.
All information shall be provided to the administrative authority as a detailed soil log for each test pit on forms supplied by the administrative authority.
If the soil logs differ significantly from each other, the authorized agent reviewing the results may require additional test pits.
The soils profile or sequence of horizons shall extend from the natural ground surface down at least four feet below the bottom of the proposed disposal bed, even if to a greater extent than the above-stated ten-foot depth.
The permeability tests of the soils within the proposed disposal bed area shall be performed in the most restrictive layer below the proposed depth of the disposal bed.
