Orono, MN Description of Waste Water Treatment System This site is an existing home with a failed septic system due to soil separation. The tanks were deemed Compliant by Kothrade Sewer and Water. There is an existing 1000 gallon septic tank and a 1650 gallon dual compartment tank. This tank has the 650 gallon compartment tank as the pump tank. This compartment will be turned into a septic tank and a new 1250 gallon pump tank must be installed. From the proposed 1250 gallon Brown Precast pump tank(Model #1250ST) effluent will be pumped 40 feet to the existing mound. The existing mound is a 1 -foot sand lift mound with a 10'x53' rockbed. The mound will be stripped of all topsoil and loamy cap and set aside. The existing rockbed and laterals will be torn out and disposed of at the proper location. It is an installers decision on how much existing sand to removed before the mound rebuild. It is estimated there is 125 -150 tons of existing sand. Once the mound is stripped of topsoils and existing rockbed, new sand will be installed to a height of 3 feet. Once 3 feet of clean washed sand is established a new 10'x50' rockbed will be installed with new laterals. The existing topsoil and loamy cap can then be re -used as a loamy cap and new top soil must be hauled in. This new on-site sewage treatment system is designed for a 4 bedroom home, Type 3 system in accordance with the MPCA Chapter 7080 and local ordinances. The soils on this site are loamy and clay loams. The periodically saturated soils were located after going to a depth of 0 inches. This will lead 6 inches of usable soil underneath the mound with a 3 sand lift. Therefore providing a 36 inch separation for the treatment of effluent above the periodically saturated soils. 1-1000 gallon septic tank will need to be re -used along with the re -used of an the existing 1650 gallon septic/pump tank. A new 1250 gallon pump tank will be installed to lift the sewage to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A warning device must also be installed with audio/visual alerts. The supply line must have drain back to the pumping chamber. From the pump tank sewage will be pumped approximately 40 feet to the mound. There will be 3- 2" pipes each 3 feet apart inside the 10' by 50' rockbed. The mound will have a total footprint of 45' by 94' with 5 percent slope underneath it. All tank manholes should be brought to grade upon completion of tank installation, inspection ports for the distribution boxes should also be at grade upon completion. Ende Septic Service, LLC, 24910 Territorial Road I ph.763-428-4489 orinfo(o)endeseotic.com 1 Keep all vehicles and construction equipment off septic area. Rutting and/or compacting the soil will change the percolation rates and may lead to system failure. Homeowner to verify all property lines and all relevant setbacks. Homebuilder and septic installation company must verify all wetland setbacks, Elevations are referenced to Bench Mark on the bottom of siding on the front of the home. Installer to verify all elevations, dimensions, and ensure proper fall to pipes. Pitch pump chamber outlet to ensure complete drain back to pump chamber. Establish turf to prevent erosion and freezing. Each tank is to be pumped through the maintenance cover when serviced. Do not pump through inspection pipes. Homeowner is responsible for all costs involved in servicing, monitoring, and mitigating the system. All construction to be performed in accordance with MN Rule 7080. Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic tank. Recommend iron filters be diverted out of the system. Recommended to divert the water softener as well. Garbage disposals are no recommend, due to adding more solids and fine solids passing through the system. Excessive amounts of soap, antibacterial soaps, cleaning agent, showers, cleaners used every shower and chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend laundering be limited to 3 loads per day. IRON FILTERS ARE NOT ALLOWED IN THE SEPTIC SYSTEM. IF AN IRON FILTER IS ISNTALLED IT VOIDS ALL WARRANTIES AND GUARANTEES OF SYSTEM LONGEVITY BY DESIGNER AND INSTALLER.

Ende Septic Service esigner Signature Company L2654 License # Owners Septic System Management Plan Date: 10/2/2019 Property Address: 2080 Salem Ct. Septic Systems can be an expensive investment, good maintenance will ensure they last a lifetime. The purpose of a septic system is to properly "decompose" the pollutants before the water is recycled back into the groundwater. If you're not taking this seriously, ask yourself where your well water comes from. Your septic design lists all the components of your system and their location. Keep the design, this management plan and the UofM "Septic System Owners Guide" in a safe place for future reference. For a copy of the Owners guide call the University of MN at 1-800-876-8636. Some of the following tasks you can do yourself, some require a professional, but is it YOUR responsibility to see that it gets done. Homeowner Tasks • Do your best to conserve water. Don't overload your septic with multiple large water uses at the same time or on the same day. • Fix household leaks promptly (leaky toilet, dripping faucets). • Limit bleach and anti -bacterial products. Use Biodegradable dishwasher detergent. • Consider a lint filter on your clothes washer. • Regularly check for wet or spongy soil around your drainfield. • Have a septic professional check your tanks every 3 years to determine if they need pumping. • If you have a septic tank filter (effluent filter) clean it on a regular basis (or have a professional do it). • If a septic alarm goes off, call your septic professional to diagnose the problem. • Notify the County/City/Township when this management plan is not being met. • Be aware of and protect your secondary drainfield site. Professional Tasks • Disclose the location of the secondary drainfield (if applicable). • Respond to alarms and diagnose problems as needed. • Review water use with the owner, check for a "soggy" drainfield. • Pump the septic tanks as needed and ensure they are in proper working order. • Verify the pump, dose amount, HI Level Alarm & drainback are all working properly. "As the owner, I understand it is my responsibility to properly operate and maintain this septic system". Property Owner Signature: Date UNIVERSITY OF MINNESOTA �\ Septic System Management Plan for Above Grade Systems The goal of a septic system is to protect human health and the environment by properly treating wastewater before returning it to the environment. Your septic system is designed to kill harmful organisms and remove pollutants before the water is recycled back into our lakes, streams and groundwater. This management plan will identify the operation and maintenance activities necessary to ensure long- term performance of your septic system. Some of these activities must 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 effective life of your system and save you money over time.

Chart on page 6 can help track your activities. Your toilet is not a garbage can. Do not flush anything besides human waste and toilet paper. No wet wipes, cigarette butts, disposal diapers, used medicine, feminine products or other trash! The system and septic tanks needs to be checked every 24 months Your service provider or pumper/maintainer should evaluate if your tank needs to be pumped more or less often. Seasonally or several times per year • Leaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly. • Soil treatment area. 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 sewage may make humans and animals sick Keep bikes, snowmobiles and other traffic off and control borrowing animals. • Alarms. Alarms signal when there is a problem; contact your service professional any time the alarm signals. • Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. If you do not have one, 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 along with an alarm. Annually • Water usage rate. A water meter or another device 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. Consider updating to demand operation if your system currently uses time, • Review your water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any major changes with your service provider or pumper/maintainer. During each visit by a service provider or pumper/maintainer • Make sure that your service professional services the tank through the manhole. (NOT though a 4" or 6" diameter inspection port.) • Ask how full your tank was with sludge and scum to determine if your service interval is appropriate. • Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4. -3- UNIVERSITY Septic System Management Plan` for Above Grade Systems OF MINNESOTA Professional Management Tasks These are the operation and maintenance activities that a pumper/maintainer performs to help ensure long- term performance of your system. At each visit a written report/record must be provided to homeowner. Plumbing/Source of Wastewater • Review the Water Use Appliance Chart on Page 5 with homeowner. 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 soil treatment area.) • Inspection pipes. Replace damaged or missing pipes and caps. • Baffles. Check to make sure they are in place and attached, and that inlet/outlet 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. • Alarm. Verify that the alarm works. • Drainback. Check to make sure it is draining properly. • Event counter or elapsed time meter. Check to see if there is an event counter or elapsed time meter for the pump. If there is one or both, calculate the water usage rate and compare to the anticipated use listed on Design and Page 2. Dose Volume: 150 gallons: Pump run time: 4.1 Minutes Soil Treatment Area Inspection pipes. Check to make sure they are properly capped. Replace caps and pipes that are damaged. • Surfacing of effluent. Check for surfacing effluent or other signs of problems. • Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean at recommended frequency. • Vegetation - Check to see that a good growth of vegetation is covering the system.
