Lab samples will be needed to test for fecal coliforms, recommend 1 time a year at a cost of$75.00 to $100.00 per test. The samples must be less than 2000 colonies/100m1 of effluent. If the sample is greater than this a new sample will need to be taken in 30 days. Inspection pipes will need to be installed to the bottom of the sand filf and bottom of the rack bed. The1st tank will be a 1000 gallon trash trap. The 2nd tank will be a 1500 gallon dosing chamber (pump #1) which will dose 18.7 gallons every 30 minutes with a timer to the Multi-Flo Unit. The effluent wifl flow gravity from the Multi-Ffo to the 2000 gallon pumping chamber (pump #2) which will pressurize the seepage bed. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A warning device must be installed with a light and sound device, this is in case of a pump faifure. The Mitigation Plan is If hydraulic overloading would occur, a timer could be installed to reduce the amount of effluent pumped to the system and also by using the 2000 gallon pumping chamber allows the effluent to be stored during peak use and pumped to the system during low water use periods. The second would be to install holding tanks. A water meter will need to be installed to monitor daily water use. The soils at a depth of 18" have a percolation rate of 11.4 mpi. All neighboring wells are located greater than 100' away from the proposed treatment area. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid &the system wilf need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. 2
