MOUND SYSTEM USER'S MANUAL PROJECT: LLIFLtq S/h7tN SYSTEM START-UP For new construction, prior to the use of the POWTS, check the treatment tank(s)for the presence of painting products, chemicals or other foreign Objects not being a part of the POWTS that may impede the treatment process and/or damage the dispersal cell(s). If high concentrations are detected, have the contents removed by a septage servicing operator prior to use. Additionally,system start-up shall not occur when sail conditions are frozen at the infiltrative surface. SYSTEM OPERATION A mound system consists of a septic tank,pump chamber,and a soil absorption cell. In the mound system construction,sand is added where suitable native soil is insufficient. Primary treatment of household waste occurs in the septic tank. Effluent from the septic tank exits through a filter to a pump chamber where it is pumped in controlled pressurized doses to an above ground,free standing sand layer. The sand layer,placed upon a specially prepared area of native soil, serves as the medium on which aerobic bacteria facilitate much of the secondary treatment.In a mound system,the sand layer and native soil combine to provide 36 inches of soil depth for treatment. Delivering effluent to the soil absorption cell in controlled doses has advantages. Wastewater is equally distributed,which reduces the chances for localized clogging. Additionally,the absorption cell has a"rest period" between doses that can result in superior pathogen and nutrient removal. During power outages,pump tank(s)may fill above normal high-water levels. When power is restored,the excess wastewater will be discharged into the dispersal cell(s)in one large dose,overloading the cell(s)and may result in the backup or surface discharge of effluent. To avoid this,have the contents of the pump tank(s)removed by a seplage servicing operator prior to restoring power to the effluent pump or contact a plumber or POWTS maintainer to assist you in manually operating the pump controls to restore normal levels within the pump tank(s). Do not drive or park vehicles over the tank(s)or dispersal cell(s). Do not drive,park over,or otherwise disturb or compact the area within 15 feet down slope of any mound or at-grade soil absorption component. MANAGEMENT &CONTINGENCY PLAN This Private Onsite Wastewater Treatment System(POWTS)has been designed,and is to be installed and maintained according to Comm 83,WI Administrative Code,the Mound Component Manual for POWTS(SBD-10691-P;(N.01/01),the Pressure Distribution Component Manual for POWTS(SBD-10706-P;(N.01/01),and the POWTS owner's County Private Sewage System Ordinance. This POWTS has been designed to accommodate a maximum daily flow of 7S 0 gallons of domestic waste per day. The quality of influent discharged 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.BOD(5) a monthly average of 150 mg/L TSS Wastewater shall not be discharged 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.NR140 Tables 1 &2 at a point standards application, except as provided in Comm 83.03(4),WI Admin.Code. The owner of this POWTS is responsible for system operation and maintenance. The following maintenance shall occur within three(3)years of the date of installation and at least once every three years thereafter: 1) The septic tank(s)(and pump chamber if applicable)shall be pumped by a certified septage servicing operator,licensed under s.281.48,WI Stats, unless inspection by a licensed master plumber or person authorized to make such inspection, finds less than one-third (1/3)of the tank volume occupied by sludge and scum. More frequent pumping may be necessary to prevent solids from exceeding 1/3 of the volume of the tank. Wastes shall be disposed of by the pumper in accordance with ch. NR113, WI Admin. Code. At each pumping,the pumper must visually inspect the condition of the tank, baffles, risers and manhole cover and verify that any required locks are present. Please note that owner must provide septage servicing operator with reasonable access to tank(s). This may include (but is not limited to) construction of a designated drive or servicing pad to within 150 horizontal feet and/or to within 15 vertical feet to bottom of the tank(s), foot traffic over and through Property,or vehicle traffic over and through property. 2) The soil absorption component(s)shall be visually inspected by a licensed master plumber, certified septage servicing operator or POWTS inspector. Inspection shall check for evidence of discharge of sewage to the ground surface and for ponding of effluent in the distribution cell(s). 3) The tank filters) shall be inspected and cleaned to remove any accumulated solids according to the manufacturer's specifications. The filter cartridge shall not be removed unless provisions are made to retain solids in the tank. Cleaning of the filter at more frequent intervals may be necessary. 4) Any pump,alarm or related electrical connections shall be visually inspected for defects and tested to confirm that they are operating properly. (if applicable) 5) Reports for all system maintenance shall be submitted to the County Government in which the POWTS is located in accordance with Comm 83.55 WI Admin. Code and the County's Private Sewage Systems Ordinance. No one should enter a septic or other treatment tank for any reason without being in full compliance with OSHA standards for entering a confined space. The atmosphere within these tanks may contain lethal gases,and rescue of a person from the interior of the tank may be difficult or impossible. No product for chemical or physical restoration or chemical procedures for POWTS may not be used unless approved by the Department of Commerce in accordance with Comm 84,WI Admin.Code.
