The soils on this site are a clay loam. The seasonally saturated soils (mottled soil were present a depth of 12" to 26". 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 & 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 V of cover, the lids, risers & maintenance hole covers must be insulated to a value of RIO. Cleanouts for each lateral with a sweep must be insulated & be accessible from finished grade in an irrigation box with a ball valve. ❑ocu Signed by: Docu Signed by, Docu Signed by: 2/3/2022Z/8/2022 1/26/2022 5979720595BC411._ 4C047144D5154D7... 3D952CBAB9834A7... DocuSign Envelope ID: D8AA32DD-94F0-4A26-ACCF-EFE01D862864 All neighboring wells are located greater than 100' away from the proposed treatment area & 70' on this site. Keep all heavy equipment off of the proposed treatment area before and after construction. New construction sites must be fenced off prior to starting construction of the home. 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 of wetness 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. 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. PAINTS, STAINS, ET.0 MUST NOT GO DOWN THE DRAINS. Recommend laundering be limited to 3 to 4 loads per day. IRON FILTERS MUST NOT DISCHARGE INTO THE SYSTEM. Steven B.

It is your job as the homeowner to be sure this happens effectively and safely. As with your car, regular maintenance and attention is needed to keep it operating efficiently in a cost effective manner. Septic 'Tank Functions: • Separates into three layers: scum {stuff tliat floats), sludge (stuff that sinks), and the liquid. • The solids and scum are held until removed by the maintainer. Anaerobic bacteria work to break down wastes, prepare the liquid for the drainfield. • The liquid is delivered to the soil treatment area to complete the treatment process. • If solids are not removed, they can end up in the soil treatment area, causing (often irreparable) damage. • Factors that increase frequency of pumping: use of garbage disposal, water treatment unit that discharges into the septic system, in-home daycare or other reason a large number of people are present most of the time, laundry on the 2nd floor, excessive use of water and strong cleaning products. Best management practices: • Tanks need to be evaluated every two to three years and pumped if necessary. Some counties require pumping on a specified basis. New homes—pump within 3-12 months of occupancy the first time. • Never allow a tank to be cleaned through the inspection pipe. This is not allowed by code, and it does not allow a good cleaning to occur. Scum can plug the baffle, baffles can be knocked off. Tanks should only be cleaned through the manhole or maintenance hole. • Be sure baffles, effluent screen, pumps and other components are inspected when the tank is pumped. • Install risers on the manhole covers to allow easier access. Insulate the cover and secure tightly. • An effluent screen will prevent most solids from reaching the soil treatment area. Install and clean according to manufacturer recommendations, • Never use additives. The cleaners are harmful to your system. They do not replace good management Practices. Starters and feeders are not effective. • Warning: NEVER go into a septic tank—there are dangerous gases and no oxygenl • Do not ignore alarms—troubleshoot the Problem. Soil b-eatment Area: Trench or. MgUn, Functions., • Soil organisms destroy pathogens (bacteria, viruses). • Remove phosphorus, reduce nitrogen content. • Recycle clean water -into the soil and ground water. Water and nutrients enter the ground water, evaporate through plants, and are used by plants. Best management practices: 4 Maintain vegetative cover (turf grass, native grasses, flowers). Mow, but do not fertilize, burn or over -water. • Keep all vehicles, bikes, snowmobiles, etc. off. • Do not plant trees or shrubs near drainfield. • Inspect for cracked, missing inspection pipe covers. • Follow practices to prevent freezing, including mulching the entire system if needed. Household Best Management !Practices Mang e water usP • Repair all leaking faucets, toilets, fixtures. a Change to low flow toilets, shower heads. • Replace appliances with low water use models. • Spread water uses evenly throughout the day and week.. • Re-route clean water sources: water softener, treatment unit recharge water, high efficiency furnace drip, sump pumps to separate drainage area. Watch whatgoes down the drain: o The toilet is not a garbage can—nothing should be flushed except human waste and toilet paper. • Excess medications --return, to pharmacy or land -fill. • Limit or eliminate drain cleaner use. • Do not use automatic toilet cleaners, disposable brushes. • Do not use every -use or automatic shower cleaners. • No hazardous waste, paints, solvents, chemicals. Use disposable paint brushes. • !Eliminate or limit use of garbage disposal. • No chlorine treated water such as from hot tubs. Mana e roduct use: • Minimize use of anti -bacterial soaps, cleansers. • Detergents; measure accurately, use as little as possible. • Limit use of bleach -based cleansers. Septage—the solids from the tank are usually land -applied. Lime is added in the truck to destroy pathogens and help control odors. Septic pumpers must follow strict guidelines to protect public safety and water quality. Septage disposal is managed by the MN Pollution Control Agency (MPGA) and the Environmental Protection Agency (EPA). For more information: Order the Septic Systcm Owner's Guide.

This management play will identify the operation and maintenance activities necessary to ensure long-term performance of your septic system, Some of these activities trust be performed by you, the homeowner. Other tasks must be performed by a licensed septic maintainer or service provider. However, it is YOUR responsibility to make sure all tasks get accomplished in a timely manner. The University of Minnesota's Septic System Owner's Guide contains additional tips and recommendations designed to extend the effcctive life of your system and save you money over time.

Use the chart on page 6 to track your activities. Identify the service intervals recommended by your system designer and your local government. The tank assessment for your system will be the shortest interval of these three intervals. Your pumper/maintainer will determine if your tank needs to be pumped. System Designer: check every pq months Local Government: check every months My tank needs to be checked State Requirernent: check every 36 months every months Seasonally or several times per year Leaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly. • Surfacing selvage. Regularly check for wet or spongy soil around your soil treatment area, If surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps and leaks, call your service professional_ Untreated selvage may make humans and animals sick. Alarms. Alarms signal when there is a problem; contact your 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 your water usage rate to the design flow of your system (listed on the next page). Contact your septic professional if your average daily flow over the course of a month exceeds 70% of the design flow for your system, Caps. Make sure 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 than time (days). Recharging too frequently may negatively impact your septic system. Review your 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 pumpeilmaintainer Ask if your pumper/maintainer is Iicemed in Minnesota. Make sure that your pumper/maintainer services the tank through tate manhole, (NOT though a 4" or 6" diameter inspection port.) 0 Ask your pumper/maintainer 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. Insulate the riser cover for frost protection. • 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 be 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 ponding in the drainf eld.) • Inspection pipes. Replace damaged caps. • Baffles. Check to make sure they are in place and attached, and that inletloutlet 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 manufacturer recommendations. • Al". Verify that the alarm works. • Drainback. Check to make sure it is operating properly. • Event counter or run time. Check to see if there is an event counter or run 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 of effluent. 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 aleanouts exist, flush and clean as needed.
