Co., MN This site has an existing on-site sewage treatment system which is hydraulically overloaded & will need to be repaired. The existing tanks are old & non compliant (pumped 8-14.18) & will need to be abandoned, pumped & filled with soil & new tanks installed. This onsite sewage treatment system is designed for a Type 1 system, Type 1, 4 bedroom home in accordance with the Minnesota (Pollution Control Agency chapter 7080 & local ordinances. The soils on this site are a clay loam. The seasonally saturated soil, mottled soil (redox features) were present at a depth of 22" to 32". A pressurized mound system will be installed. The bottom of the treatment area must be located at least 3' above mottled soil. A pumping chamber will need to be installed to lift the effluent to the treatment area. 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 R sound device, this is in case of a pump failure. The manifold & supply line must have back drainage to the pumping chamber. Be sure the rock & sand fill material are clean. The sod layer below the entire mounded area must be turned over, just break up the sod. All property lines must be located prior to installation. 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. All neighboring wells are located greater than 100' away from the proposed treatment area. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This design is not valid & the system will need to be relocated if failure to protect the sites for new on-site sewage systems. MANAGEMENT PLAN: The tanks need to be maintained at a minimum of 1 time every 2 years, check with your pumper to set up a schedule. System inspected for areas by owner & or Inspector as determined by the local unit of Government. Any other requirements as determined by the local unit of Government. With proper installation & maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than human waste, toilet tissue, laundry, showers, water softners etc. should be disposed of into the system. Recommend iron filters be diverted out of the system. Garbage disposals are not recommended. Excessive amounts of soaps, antibacterial soaps, cleaning agents, shower cleaners used every shower & chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend laundering be limited to 3 to 4 loads per day. Steven B.

Check (listen, look) fm leaks in toilets and dripping faucets. Repair leaks promptly. • Surfacing sewage. Regularly check for wet or spongy soil around you soil treatment area. If surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps and leaks, call you service professional. Untreated sewage may make humans and animals sick. • Alarms. Alarms signal when there is a problem: contact you maintainer any time the alarm signals. • Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. Consider adding one after washing machine. • Effluent screen. If you do not have one, consider having one installed the next time the tank is cleaned. Annually • Water usage rate. A water meter can be used to monitor your average daily water use. Compare you watts usage rate to the design flow of Yom system (listed on the next page). Contact you septic professional if you average daily flow over the course of a month exceeds 70% of the design flow for you system. • Caps. Make sore that all caps and lids are intact and in place. Inspect for damaged caps at least every fall. Fix or replace damaged caps before winter to help prevent freezing issues. • Water conditioning devices. See Page 5 for a list of devices. When possible, program the recharge frequency based on water demand (gallons) rather floor time (days). Recharging too frequently may negatively impact you septic system • Review, you water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any major changes with Your pumper/maintainer. During each visit by a pumper/maintainer • Ask if you pumper/maintainer is licensed in Minnesota. • Make sure that you pumper/maintainer services the tank through the manhole. (NOT though a 4" or 6" diameter inspection port) • Ask you pumper/maintain, to accomplish the tasks listed on the Professional Tasks on Page 4.

Discuss any changes in water use and the impact those changes may have on the septic system. • Review water usage rates (if available) with homeowner. Septic Tank/Pump Tanks • Manhole lid. A riser is recommended if the lid is not accessible from the ground surface the riser cover for frost protection. Insulate • Liquid level. Check to make sure the tank is not leaking. The liquid level should be level with the bottom of the outlet pipe. (If the water level is below the bottom of the outlet pipe, the tank may not he watertight. If the water level is higher than the bottom of the outlet pipe of the tank, the effluent screen may need cleaning, or there may be pending in the drainfield.) • Inspection pipes. Replace damaged caps. • Baffles. Check to make sure they are in place and attached, and that inlet/oudet baffles are clear of buildup or obstructions. • Effluent screen. Check to make sure it is in place; clean per manufacturer recommendation. Recommend retrofitted installation if one is not present. • Alarm. Verify that the alarm works. • Scum and sludge. Measure scum and sludge in each compartment of each septic and pump tank, pump if needed. Pump • Pump and controls. Check to make sure the pump and controls are operating correctly. • Pump vault Check to make sure it is in place; clean Per an ouf tcturer recommendations. • Alarm. Verify that the alarm works. • Drainback, Check to make sure it is operating properly. • Event counter or run fime. Check to see if there is an event counter or ran time log for the pump. If there is one, calculate the water usage rate and compare to the anticipated average daily flow listed on Page 2. Soil Treatment Area • Inspection pipes. Check to make sure they are properly capped Replace caps that are damaged. • Surfacing ofeftuent. Check for surfaced effluent or other signs of problems. • Gravity trenches and beds. Check the number of gravity trenches with ponded effluent. Identify the percentage of the system in use. Determine if action is needed. • Pressure trenches and beds - Lateral flushing. Check lateral distribution; if cluanouts exist, flush and clean as needed.
