It is imperative that all food by-products and food wastes be handled as solid wastes and not be disposed of into the septic system. Consequently,there cannot be a garbage disposal or grinder installed in the kitchen sink(s). This will prevent concentrated organic loading and prolong the lifespan of the wastewater disposal system. All plumbing fixtures should be of the lowest flows available. Faucets for feet washing must be spring-loaded, or infrared activated with timers and not be allowed to run continuously. A water softener must not be installed on the domestic water supply line since the sodium liberated could deflocculate the clay soil and collapse the soil structure. The Conditions of Approval state in Item lb: This approval is for the expansion of a previouslys approved religious facility for up to 81 people to be built in two phases as shown on the Site Plan / v� dated December 8, 2010. Under the EHD Conditions of Approval Item C: Should the number of non-resident individuals exceed 24 for at least 60 days per year, or the number of service connections exceed four, a yearly permit to operate a public water system will be required by the EHD. Since a maximum of 81 people will be on-site only every Saturday of each calender year (52x),the facility will not exceed the"60 days per year"requirement and the existing on-site well will operate as a private domestic well and not a public well. The maximum Average Daily Flow(ADF) is calculated to be 810 gals/day. The Application Rate for the 42 inch test depth at the proposed soil-effluent interface is presently 0.545 gals/ft/day, based upon the percolation test results. Floor area and two-foot sidewall area= 240 ft' x four leachlines= 960 W. 0.545 gals/112/day x 960 ftZ = 523 gals/day that the soil-effluent-interface leachline trench soils can theoretically accept and manage. This is under the ADF by: 810 ADF - 523 =287 gals of effluent. (r,� However, factoring in the seepage pits, we find that the entire system can manage 810 ADF: l 4 ft dia. pits=265 ft'x 4 pits= 1060 ftZ x .417 gals/ftZ/day=442 gals/day+ 523 gals/day=965 gals/day. Mr. Arvind Iyer as the architect,the plumber, the landscaper, and the septic system installer must all coordinate so that proper grades are established and maintained. In addition, effluent lines should not cross fresh water or electrical lines. If crossing cannot be avoided, the wastewater lines should cross under fresh water lines and be adequately encased per EHD guidelines. MONITORING A water meter should be installed (per EHD guidelines) on the service line entering the facility to monitor and ensure water usage is not excessive. Restricting water use also includes checking for ✓ water leaks in toilets, dripping faucets, etc. on a regular monthly basis. Given that the blackwater wastes inflowing into the septic tank are projected to be a very small volume, it is anticipated to have the tank pumped every five years, or pump-out based upon monitoring the scum and sludge thicknesses by a septic contractor after two years of operation. 12
