The existing mound is not worth fixing due to its age and is better off being replaced. A new mound is being designed northeast of the existing mound near the wooded patch of the lot. There are about 6-10 trees that will need to be cut down. The existing tanks on the property will need to be pumped, crushed and abandoned. Two new 1250 gallon septic tanks will be installed along with a 1250 gallon pump tank. From the pump tank effluent will be pumped approximately 85 feet to the newly proposed mound. The proposed mound will have a 10'x62.5' rockbed with a 2 foot sandlift under the rockbed. A flow measurement device must be installed and the existing iron filter must be routed out of the septic system. This new on-site sewage treatment system is designed for a 5 bedroom home, Type 1 system in accordance with the MPCA Chapter 7080 and local ordinances. The soils on this site are loamy. The periodically saturated soils were located after going to a depth of 12 inches. This will lead 12 inches of usable soil underneath the mound with a 2 foot sand lift. Therefore providing a 36 inch separation for the treatment of effluent above the periodically saturated soils. 2-1250 gallon tank will need to be installed along with the installation of a 1250 gallon pump tank 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 85 feet to the mound. There will be 3- 2" pipes each 3 feet apart inside the 10' by 62.5' rockbed. The mound will have a total footprint of 47' by 99' with 6 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. Keep all vehicles and construction equipment off septic area. Ruttinq_ and/or com_pactinq_ 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 in the back of the home. Ende Septic Service, LLC, 24910 Territorial Road 1ph.763-428-4489orit7fo(@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. Maintenance Requirements See attached operating permit or management plan for details it IF AN IRON FILTER IS ALLOWED TO DISCHARGE INTO THE SEPTIC TANKS AND SEPTIC SYSTEM ALL WARRANTIES AND EXPECTATIONS OF LONGEVITY ARE VOIDED BY THE INSTALLER AND THE DESIGNER. IRON FILTERS ARE NOT ALLOWED TO DISCHARGE INTO SEPTIC SYTEM. THE IRON FILTER SHOULD HAVE ITS OWN TANK AND TRENCH SYSTEM INSTALLED TO TREAT IRON FILTER DISCHARGE WASTE.

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 alone 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 pamper/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.

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. Verifv 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.
