11/28/2020 SSTS Design 12408 228th Street North Scandia, MN 55073 PID # 09.032.20.22.0035 Version 1.0 Kloeppner Services & Designs, LLC MPCA LICENSE # 4043 763.843.4114 CONNECT@KSD‐MN.COM Prepared by KSD @ 2020 www.ksd‐mn.com SSTS Design Summary Report 11/28/20 On November 19th, 2020, a site evaluation was conducted at 12408 228th St N, Scandia, MN 55073 to design a new Subsurface Sewage Treatment System (SSTS) for an existing 2‐bedroom home. The PID number is 09.032.20.22.0035. Prior to submitting for permit from Washington County please review and sign all pages which require a signature. Wastewater Sources & Peak Flow Rate The expected waste strength is Residential Wastewater with a Peak flow of 300 gallons per day (GPD) for a 2‐bedroom house. The Expected Daily Flow should be less than 70% of the Peak Flow (210 GPD). Type III ‐ Mound The dispersal area will be a Type III Mound. The Mound Soil Absorption Area required is 600 sqft (20’ x 30’). The existing At‐Grade will be removed, and the new mound will be built in the same footprint. The minimum required materials for the sewer line, distribution network, pumps, supply line, sand, rock, fill and cover are detailed in the design worksheets included with this design. Actual values may change slightly and will need to be field verified for correctness. Design Notes 1. Reuse existing Tanks: 1st Tank ‐ 1,500‐gallons (split compartment) and Pump Tank ‐ 1,000‐ gallons (single compartment). 2. Existing Tanks must be certified by licensed Maintainer (Pumper) or Inspector to be water‐tight and structurally sound. 3. Existing At‐Grade Rockbed and Soil Cover must be removed. Handle all contaminated soil as sewage and hazardous waste. 4. Prepare soil below mound absorption area carefully throughout 20' x 30' Soil Absorption Area. Be careful not to compact soil during deconstruction of At‐Grade. 5. Time‐Dosing Control Panel will be used to control flow to a maximum of 210‐gallons per day and measure usage daily. 6. A High‐Level Alaram will be activated if household uses more that 210‐gallons is a 24‐hour period. 7. A small retaining wall may be necessary to allow access to door of Garage. Discuss options and costs with homeowners. 8. The existing Sewer and Pump Supply Lines must be inspected if either is reused. 9. Northwest end of mound berm calculation extends beyond small deck to south of the house. Installer must discuss options to blend berm or build retaining wall beyond the absorption are to keep soil cover from impacting deck. Construction Notes Building Permit requirements No construction shall be allowed by any local unit of government until the permit required for the subsurface sewage treatment system has been issued. Site Protection Prior to and during construction or lot improvements, the proposed initial and replacement soil treatment and dispersal areas shall be protected from disturbance, compaction, or other damage by use of stakes and silt fence or snow fence. Prepared by KSD @ 2020 www.ksd‐mn.com MR 7080.2100, Subpart 1. F Electrical installations must comply with applicable laws and ordinances including the most current codes, rules, and regulations of public authorities having jurisdiction and with part 1315.0200, which incorporates the National Electrical Code. As‐Built Drawing The Licensed Installer must provide an As‐Built of the final location of all components. The attached Site Plan is only for reference and should not be considered as final survey or location of system components. Protection from Freezing for Supply Line The Mound supply line must drain back and empty pipe after each dose. To avoid potential freezing, additional depth or insulation may be necessary to keep line from freezing if buried too shallow. Soil Erosion & Protection from Freezing The dispersal area must have seed and grass established throughout the excavated areas to maintain proper protection from soil erosion and freezing. 12408 228th St N, Scandia 0 20 4010 ft 0 7 143.5 m 1:2 50 Disclaimer: Map and parcel data are believed to be accurate, but accuracy is not guaranteed.

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

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 _____ 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. Septic System Management Plan for Above Grade Systems - 4 - 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: __________ 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. All other components – evaluate as listed here: Septic System Management Plan for Above Grade Systems - 5 - Water-Use Appliances and Equipment in the Home Appliance Impacts on System Management Tips Garbage disposal •Uses additional water. •Adds solids to the tank. •Finely-ground solids may not settle. Unsettled solids can exit the tank and enter the soil treatment area. •Use of a garbage disposal is not recommended. •Minimize garbage disposal use. Compost instead. •To prevent solids from exiting the tank, have your tank pumped more frequently. •Add an effluent screen to your tank. Washing machine •Washing several loads on one day uses a lot of water and may overload your system. •Overloading your system may prevent solids from settling out in the tank. Unsettled solids can exit the tank and enter the soil treatment area. •Choose a front-loader or water-saving top-loader, these units use less water than older models. •Limit the addition of extra solids to your tank by using liquid or easily biodegradable detergents. Limit use of bleach-based detergents and fabric softeners. •Install a lint filter after the washer and an effluent screen to your tank •Wash only full loads and think even – spread your laundry loads throughout the week. Dishwasher •Powdered and/or high-phosphorus detergents can negatively impact the performance of your tank and soil treatment area. •New models promote “no scraping”. They have a garbage disposal inside. •Use gel detergents. Powdered detergents may add solids to the tank. •Use detergents that are low or no-phosphorus. •Wash only full loads. •Scrape your dishes anyways to keep undigested solids out of your septic system. Grinder pump (in home) •Finely-ground solids may not settle. Unsettled solids can exit the tank and enter the soil treatment area. •Expand septic tank capacity by a factor of 1.5. •Include pump monitoring in your maintenance schedule to ensure that it is working properly. •Add an effluent screen. Large bathtub (whirlpool) •Large volume of water may overload your system. •Heavy use of bath oils and soaps can impact biological activity in your tank and soil treatment area. •Avoid using other water-use appliances at the same time. For example, don’t wash clothes and take a bath at the same time. •Use oils, soaps, and cleaners in the bath or shower sparingly. Clean Water Uses Impacts on System Management Tips High-efficiency furnace •Drip may result in frozen pipes during cold weather. •Re-route water directly out of the house. Do not route furnace discharge to your septic system. Water softener Iron filter Reverse osmosis •Salt in recharge water may affect system performance. •Recharge water may hydraulically overload the system. •These sources produce water that is not sewage and should not go into your septic system. •Reroute water from these sources to another outlet, such as a dry well, draintile or old drainfield. •When replacing, consider using a demand-based recharge vs. a time-based recharge. •Check valves to ensure proper operation; have unit serviced per manufacturer directions Surface drainage Footing drains •Water from these sources will overload the system and is prohibited from entering septic system.
