NE, Hanover, MN 55341 (763) 498-8779 Fax (763) 498-8290 Revised May 23, 2022 Norton Homes 685 Pinehurst Court Orono, Hennepin County This on-site Sewage Treatment System is designed for a Type 1, five -bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The periodically saturated soils were located at 18-28 inches (mottled soil). Due to the periodically saturated soils, a pressurized mound system with 6 inches of rock will need to be installed to treat the septic effluent. The bottom of the treatment area must be located at least 3' above the saturated soils. This system is designed with 6 inches of rock. A 2250 -gallon combination septic tank or its equivalent is designed for this site. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks. Clean outs must be installed on the end of the laterals for maintenance. The supply line must be insulated and sleeved under the driveway Use 7/32 -inch perforations on the laterals. A 1250 -gallon pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with light and sound devices; this is in case of a pump failure. A flow measurement device must be installed. Including but not limited to a water meter, event counter, running time clocks or electronically controlled dosing. Keep all heavy euuinment_off of the Proposed treatment areas before, during and after construction. The area around both sites must be fenced off by the contractor before any construction beeins. With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than gray water, (laundry, showers, etc.) Human water and toilet tissue should be disposed of into the septic tanks. Iron filters and water treatments stems cannot go into the septic system. Garbage disposals are not recommended. Additives must not be used they may cause harmful damage to your septic system. It is recommended that you pump the septic tanks every two years. Sincerely, Joseph J.

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 pian 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. Proper septic system design, installation, operation and maintenance means safe and clean water!

The Septic System Owner's Guide includes a folder to hold maintenance records including pumping, inspection and evaluation reports. Ask your septic professional to also: • Attach permit information, designer drawings and as -built of your system, if they are available. • Keep copies of all pumping records and other maintenance and repair invoices with this document. • Review this document with your maintenance professional at each visit; discuss any changes in product use, activities, or water -use appliances.

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 fir` These are the operation and maintenance activities that apumper/maintainerperforms to help ensure long- term performance ofyour 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: 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. • 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.
