Mound System Management Plan <br /> Pursuant to Comm 83.54,Wis.Adm.Code <br /> General <br /> This system shall be operated in accordance with Comm 82-84 Wis.Adm.Code,and shall maintained In accordance with its component <br /> manuals(S80.1001-p(N.01/01)and SSWMP Publication 9.6(01/81)1 and local or state rules pertaining to system maintenance and <br /> maintenance reporting. <br /> No one should ever enter a septic or pump tank since dangerous gases may be present that could cause death. <br /> Septic and pump tank abandonment shall be in accordance with Comm 83.33,Wis.Adm.Code when the tanks are no longer used as <br /> POWTS components. <br /> Septic or pump tank manhole risers,access risers and covers should be inspected for water tightness and soundness. Access openings <br /> used for service and assessment shall be sealed watertight upon the completion of service. Any opening deemed unsound,defective,or <br /> subject to failure must be replaced. Exposed access openings greater than 8-inches in diameter shall be secured by an effective locking <br /> device to prevent accidental or unauthorized entry into a tank or component. <br /> Seatfc Tank <br /> The septic tank shall be maintained by an individual certified to service septic tanks under s.281.48,Stats. The contents of the septic tank <br /> shall be disposed of in accordance with NR 113,Wis.Adm.Code. The operating condition of the septic tank and outlet finer shall be assessed <br /> at least once every 3 years by inspection. <br /> The outlet filter shall be cleaned as necessary to ensure proper operation. The filter cartridge should not be removed unless provisions are <br /> made to retain solids in the tank that may slough off the filter when removed from its enclosure. if the filter is equipped with an alarm,the filter <br /> shall be serviced if the alarm is activated continuously. Intermittent filter alarms may Indicate surge flows or an Impending continuous alarm. <br /> The septic tank shall have its contents removed when the volume of sludge and scum in the tank exceeds 1/3 the liquid volume of the tank. If <br /> the contents of the tank are not removed at the time of a triennial assessment,maintenance personnel shall advise the owner of when the next <br /> service needs to be performed to maintain less than maximum scum and sludge accumulation in the tank. <br /> The addition of biological or chemical additives to enhance septic tank performance is generally not required. However,if such products <br /> are used they shall be approved for septic tank use by the Department of Commerce. <br /> Pump Tan <br /> P every The pump(dosing)tank shall be inspected at least once eve 3years. All switches,alarms,and pumps shall be tested to verily proper <br /> operation. If an effluent filter is installed within the tank it shall be Inspected and serviced as necessary. <br /> M12gnd and Pressure Distribution System <br /> No trees or shrubs should be planted on the mound. Plantings may be made around the mound's perimeter,and the mound shall <br /> be seeded and mulched as necessary to prevent erosion and to provide some protection from frost penetration. Traffic(other than for vegetative <br /> maintenance)on the mound Is not recommended since soil compaction may hinder aeration of the infiltrative surface within the mound and snow <br /> compaction In the winter will promote frost penetration. Cold weather Installations(October-February)dictate that the mound be heavily mulched <br /> as protection from freezing. <br /> Influent quality into the mound system may not exceed 720 mg/L BOO.,150 mg/L TSS,and 30 mg/L FOG for septic tank effluent or <br /> 30 mg/L BOD.,30 mg/L TSS,10 mg/L FOG,and 10'cfu/100 mL for highly treated effluent. Influent flow may not exceed maximum design flow <br /> specified in the permit for this installation. <br /> The pressure distribution system is provided with a flushing point at the end of each lateral,and it Is recommended that each lateral be flushed <br /> of accumulated solids at least once every 18 months. When a pressure test is performed it should be compared to the initial test when the <br /> system was installed to determine if orifice clogging has occurred and if orifice cleaning Is required to maintain equal distribution within the <br /> dispersal cell. <br /> Observation pipes within the dispersal cell shall be checked for effluent ponding. Ponding levels shall be reported to the owner,and any levels <br /> above 6 Inches considered as an impending hydraulic failure requiring additional,more frequent monitoring. <br /> Contingency Plan <br /> If the septic tank or any of its components become defective the tank or component shall be repaired or replaced to keep the system <br /> in proper operating condition. <br /> If the dosing tank,pump,pump controls,alarm or related wiring becomes defective the defective component(s)shall be immediately <br /> repaired or replaced with a component of the same or equal performance. <br /> If the mound component fails to accept wastewater or begins to discharge wastewater to the ground surface,it will be repaired or replaced in <br /> its'present location by increasing basal area if toe leakage occurs or by removing biologically clogged absorption and dispersal media,and related <br /> piping,and replacing said components as deemed necessary to bring the system into proper operating condition. <br /> See Page 6 of this plan for the name and telephone number of your local POWTS regulator and service provider. <br /> Project: Warrick Mound Page 6 of 8 <br />
