There are 2 existing 1000 -gallon tanks that are compliant and can be re -used in the installation of the new septic system. From the outlet of the second existing septic tank, effluent will gravity flow to a proposed 1000 -gallon Brown Precast pump tank. (Model#1 000 -PT) From the pump tank effluent will be pumped by a Gould PE51 effluent pump 110 feet to the northeast. The pump will dose the trench system 4 times per day with a 150 gallon dose volume. The proposed trench system will have 1 end fed distribution boxes and 3 center fed distribution boxes. Each distribution box will have 1 or 2 trench installed from southwest to northeast. Each set of trenches will be installed 6-9 ft on center to the west. There will be a total of 7 distribution boxes installed west of the home. The 7 distribution boxes will feed a total of 7-36.6 ft long trenches. Trenches are proposed to have 6 inches of rock below the drainfield pipe. Ez flow trenches from infiltrator can be used in place of aggregate. The trench system is proposed in an area that has many trees. The trenches should fit between all of the large trees. There may be some small trees that need to be dug out. Drainfield and tanks are proposed more than 20 feet from all property lines. This new on-site sewage treatment system is designed for a 4 -bedroom home, Type 1 system in accordance with the MPCA Chapter 7080 and local ordinances. The soils on this site are sands. The periodically saturated soils were located after going to a depth of 60 inches. This will provide 36 inches of separation with the deepest trench being installed 24 inches deep or shallower. 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. 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 from the survey provided by DeMarc Land Surveying Ende Septic Service, LLC, 24910 Territorial Road I ph.763-428-4489 orinfo()endeseptic.com 1 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.

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.

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 Plangio OF MINNESOTA for Below Grade Systems 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: 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. • Gravity trenches and beds. Check the number of gravity trenches with effluent ponded in distribution media. Identify the percentage of the system in use. Determine if action is needed. • Pressure trenches and beds - 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.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equakarea conic projection, should be used if more accurate calculations of distance or area are required.
