All property line will need to be located prior to installation. The first tank will be a 2000 gallon dual chamber tanks reversed using the 750 gallon side as the trash trap & the 1250 gallon side as a dosing chamber(pump #1) which will dose 15.6 gallon every 30 minutes with a timer to the Multi-Flo Unit. The effluent will flow gravity from the Multi-Flo to a new 1500 gallon pumping chamber (pump #2) flowing through a Sa10Cor UV Light which will pressurized the seepage bed. The power supply & switches must be located outside the manhole & pumping chamber in a weather proof enclosure. A warning device must be installed with a light & sound device. This is in case of a pump failure. Monitoring of the drainfield, UV Lighting & fecal coliform testing is required immediately after the system is installed. 2017 Service contract for Multi-Flo is $225.00, monitoring drainfield 1 x a year is $50.00 when we service the Multi-Flo & a Fecal Coliform test is required 1 x a year at $90.00. Price subject to change. An operating permit is required with the County at all times. If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers must be insulated to a value of R10. Cleanouts for each lateral with a sleeve must be insulated & be accessible from finished grade in an irrigation box with a ball valve. A water meter or event counter must be installed to monitor daily water use. The homeowner is responsible for the water meter readings. 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 1500 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. All neighboring wells are located greater than 100' away from the proposed treatment area.
