CONVENTIONAL SYSTEM USER'S MANUAL PROJECT- 'E { 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 soil conditions are frozen at the infiltrative surface. SYSTEM OPERATION A conventional in-ground septic system consists of a septic tank and a subsurface soil absorption cell (see plot plan). In the septic tank,solids settle out of the waste stream and anaerobic bacteria facilitate the partial breakdown of organic matter(primary treatment). Clarified effluent from the septic tank discharges via gravity flow through an effluent filter to the soil absorption cell. The soil absorption cell removes pathogens, organic matter, and suspended solids from the septic tank effluent via physical filtration,biological reduction of contaminants by aerobic microorganisms,and ion bonding to negatively charged clay particles(secondary treatment), The soil serves as a fixed porous medium on which beneficial microorganisms grow. These organisms teed on organic matter present in the wastewater and help eliminate pathogens. Three feet of suitable soil between the distribution cell and bedrock or high groundwater is sufficient to protect public health and groundwater quality. This system type requires about five feet of suitable native soil. The conventional system is a passive system that relies on gravity flow. The flow volume entering the septic tank controls the volume discharged to the soil absorption cell. The effectiveness of a conventional system depends on the type and permeability of native soils and the slope and drainage pattern of the site. The septic tank requires periodic pumping as determined by State and County Code,as well as inspection of the soil absorption cell.the effluent filter component also requires periodic maintenance. 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 Admin. Code, the Conventional Soil Absorption Component Manual for(POWTS SBD-10706-P; Jan 30 2001) (, and the POWTS owner's County Private Sewage System Ordinance. This POWTS has been designed to accommodate a maximum daily flow of kegallons 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 it 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 filter(s) shall be inspected and cleaned to remove any accumulated solids according to the manufacturers 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
