The project began in 1990 and 1991 with soil and site evaluations for a groudn absorption system to accommodate the proposed dining hall for expansion of the existing camp and conference center. The presen tdesign waste flow is 2850 gallons perday. 2,100 gallons form the dining hall and 720 gallons from teh sleeping units. The area proposed for drainfield installatioin was about 3500 feet away from the facility which required extensive design considerations. The long term acceptance rate of teh site is .1 gpd/square foot. the system incorporates 6,000 linear feet of LPP drainline in 8 zones of varying lengths (from 403 to 992 linear feet). Therefore individual time controllers for each zone were needed. The maindosing station uses two 2 HP pumps and 8 motor actuated ball valves to distribute the effluent. The control panel was built with excess capacity to accommodate future zones.

An added feature to the system is an above grade sand filter which is dosed by a suspended LPP system directly from teh lift station discharge. The system incorporates:

• 2 x 1000 gallon STB tanks for grease separation
• a 4000 gallon septic tank
• a 4000 gallon pump chamber
• approximately 3300 feet of 4" force main
• a 6000 gallon dosing chamber
• 6,000 linear feet of LPP drainfield in 8 auto valved zones
• 8 motor-actuated ball valves controlled by a control panel with feedback monitors and alarms.

the system has been in operatio nfor about one and a half years. In that time the only significant problems have been malfunctions of the autmated ball valves requiring repair and replacement. Also there has been significant odor porblems at teh sand filter. This was controlled initially by arranging the dose in the middle of teh night. this past summer however, the neighbors complained of continuing noxious odors when the sand filter dosed. The Camp has arranged to have a biological additive dosed into the waste stream to control odors.
