ATTACHMENT 5 LEACHLINES AND SEEPAGE PITSthe g Two leachlines will serve as a secondary disposal field,and based uPo6 inch diameter seepage pit, Each leachline will be 40 feet long. At the end of each line will be 2 148 ft'-)=776 ft2. lb feet deep. Total application area= 2 ft.+2 ft+ x 2ft X 320 +2(113 ft')= 5463=4,084 gals Total temporary storage volume=2 ft x 2 ft x 40 ft ; SEPTIC SYSTEM OPERATION The septic system for the proposed facility is designed to operabuilding,s follows:and wash water influent from Kitchen water from both the existing building and the newg clean-up of kettles,utensils,etc.plus floor drains will flow into the grease trap. Effluent from the grease trap will gravity to the secondary tank- All blackwater from toilets and graywater from sinks from both buildings v ill flow into the 2,000 gallon primary tank. The majority.of digestion_and paper accumulation will occur in this`tank. dary tank' The second compartment Effluent from this tank will gravity to the 1,200 gallon secon of this tank will have a dual pump system with a filter vault and an alarm system. The effluent this tank will be pumped to a hydrosplitter®valve that will split the effluent flow equally -. from its• The filter bed should be considered as between the chambers, and the leachlines and seepage p the primary disposal area. Effluent pumped to the leachlines and seepage pits will of course,be under pressure. sorthe Effl p P must first come into a settling tank. The approximate volume per dose will be gallons, tank should be a minimum of 250 gallons in volume.

CONCLUSIONS AND RECOMMENDATIONS Paramount to every issue regarding the septic system for this project,is td ino kitchen area waterthat usage be kept to an absolute minimum. Running water must not be alio Clean-up, including floor washing must be at a minimum. Low flow volumeaterilets anspring- the loaded sink faucets must be used in the restrooms. Not only will minim usage alloentire septic system to function as intended,but decreased water usage will alleviate nitrate loading. A water meter will be installed for this facility, so an accurate fresh of ter usage can be kept. However,with the Chocoholics facility,not all incoming ng of "low- be septic system effluent water. A percentage of fresh water will on d the ently,water fat" chocolate and a percentage will be used.for landscaping irrigation, 1, usage accounting will be important �y The nitrate loading calculations illustrate that the anticipated number of people on the property will contribute approximately 67% of the MCL for nitrate from the effluent recharge.
