Notes/ Maintenance Requirements MANAGEMENT PLAN This private onsite wastewater(POWTS)has been designed,and is to be installed and maintained in accordance with SPS 383,Wis.Admin. Code,the in-Ground Soil Absorption Component Manual for Private Onsite Wastewater Treatment Systems Version 2.0 SPS-10705-P (N.01/01). GeoMat in ground Component manual April 2019 Version. 1.This POWTS has been designed to accommodate a maximum daily flow of 30—Wons of wastewater per day. The quality of influent discharge into the POWTS treatment or dispersal component shall be equal to or less than all of the following. A monthly average of 30 mg/L fats,oil and grease A monthly average of 220 mg/L BOD5 A monthly average of 150 mg/L TSS Wastewater shall not discharge to the POWTS in quantities or qualities that exceed these limits or that result in exceeding the enforcement standards and preventative action limits specified in ch.NR 140Tables 1 &2 at a point of standards application,except as provided in DSPS 383.03(4),Wis Admin.Code. 2.The owner of this POWTS is responsible for system operation and maintenance. 3.Defects or malfunctions identified during maintenance described above shall be repaired in conformance with SPS383 Wis.Admin.Code, and the pertaining county Private Sewage Systems Ordinance. The user's manual,provided to the owner of the POWTS includes the names and telephone numbers of the properly licensed individuals to contact for such repairs. 5.No product for chemical or physical restoration or chemical or physical procedures for POWTS may be used unless approved by the Dept. of Commerce in accordance with SPS.384,Wis.Admin.Code. 6.If the POWTS is replaced,or its use discontinued,it shall be abandoned in accordance with SPS 383.33,Wis.Admin.Code. NOTES Two Effluent Filters to be installed where possible 1 to be installed in ST,and or 1 in pump tank in order to insure particle size less than or equal to 1/8". Filters should be cleaned once in spring,and once in fall. Also,strainers in sinks in the building shall be maintained,so that solids and fats are minimized to flow into system. A minimum of 2 observation pipes per cell shall be installed. These pipes shall be located approximately at the end of each cell. The plumber,or county shall see to it that a copy of these plans including this page,maintenance folder,and maintenance agreement is given to the homeowner. This system may contain a dose chamber. If a pump,float,electrical outage causes the dose tank to fill,the homeowner should see to it that the effluent level in the tank is brought down gradually and not all dosed to the system at once. One large dose could cause damage. Contact a pumper or your installer if this problem occurs. The homeowner is responsible for formulating a water conservation plan that will ensure the system is rarely overloaded. I.E.spread laundry out over time,not 6 loads in 2 hours,while everybody showers,and uses the toilet,ETC. CONTINGENCY PLAN FOR COMPONENT FAILURE A. Septic Tank.Any structural failure resulting in cracks or leaks in the tank must be corrected by replacement of the septic tank component. Leaks in the joints between manhole risers or covers shall be repaired by replacing faulty seals with approved materials to make joints water- tight. B.Outlet Filter.The outlet filter shall be replaced or repaired when it is either no longer capable of preventing the discharge of particles larger than 1/8 inch or when it has become permanently degraded by clogging so as to interfere with the design flow out of the septic tank. C.Dosing chamber and pump.The dosing chamber shall be replaced if any structural failure is found.Leaks in joints between manhole risers or covers shall be repaired by replacing faulty seals with approved materials to make joints water-tight.The pump and controls shall be replaced when they are no longer capable of functioning according to the design plan. D.Pressure Distribution Piping.Partial clogging of the distribution network may result in unduly long dosing cycles.The ends of the distribution laterals may be exposed and the threaded end caps removed.The piping can be disconnected on the outlet end of the pump. The distribution piping may then be back flushed to cleanse any accumulated matter from the piping. It is recommended that the dosing chamber then be pumped by a licensed plumber. E.Soil Absorption Cell.The discharge of sewage or wastewater to the ground surface is strictly prohibited due to the human health hazard created by the effluent.All failures created by surface discharge shall immediately be reported to the appropriate county.The pump shall then be immediately disconnected to prevent further discharge to the ground surface via the soil absorption cell.The existing septic tank and dosing chamber shall be used as a temporary holding tank until the necessary repairs to the soil absorption cell can be achieved.The replacement shall be initiated only after any necessary plan approvals have been obtained from the appropriate plan review authority and the required sanitary permit is obtained from the county.
