HomeMy WebLinkAbout03 -May 8, 2019 Septic Design Report1 | P a g e 5/8/19 Carmelite Monastery 8249 Demontreville Trail N Lake Elmo MN 55042 SSTS Design Summary Report On April 19th, 2019, a site evaluation was conducted at 8249 Demontreville Trail N, MN 55082 in Washington County. The PID number is 09.029.21.12.0002 Scope of Report The purpose of the design report is to create a plan for a new sub-surface treatment system to treat wastewater from the new chapel to be built at the address above. This design details the plan for the re quired tanks and soil treatment dispersal areas per Washington County Development Code, Chapter Four Subsurface Sewage Treatment System Regulations, Ordinance 206. The system is designed for an Assembly Hall w/ no kitchen plus two (2) full-time employees which will be at the Chapel during day. The system components will be a Type I designed Mound and a total of three Septic & Pump Tanks (1,000- gal; 1,000-gal & 1,000-gal).See Site Plan. Preliminary & Field Evaluation Work The Washington County Maps GIS data (https://maps.co.washington.mn.us/WCGIS/) was used to determine all property lines, utility Right of Ways, roads and other necessary features required by Ordinance 206, Section 9, Subparts 9.2 thru 9.3 prior to and during site evaluation. See Site Plan for details. The information available at MN Well Index (https://mnwellindex.web.health.state.mn.us/) does not indicate the location of any wells within 100 feet of the proposed area. Section MN Well Index – Research. The Web Soil Survey data (https://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx), which is provided by the USDA, was gathered to determine the soil characteristics of the area prior to a field evaluation. See Section Web Soil Survey – Research for more details. The field evaluation included staking a 50’ x 26’ soil absorption area, measurements from all setbacks and property line, elevations for absorption area, tanks and soil observations and a minimum of four (4) soil observations within or on the edge of the proposed absorption area for the Soil Treatment Area (STA) and an additional four (4) soil observations were conducted in second Soil Treatment Area identified for future use located to the South of the new Mound. Soil Observations The soil borings and pits were conducted, classified and recorded to meet the Washington County Ordinance 206, Section 9, 9.5 thru 9.7. Redox was observed in all Borings & Soil Pits. The limiting layer was observed at 14” at SB1. See attached Soil Observation Logs. teinbrecher S ROLL-OFFS SEPTIC SYSTEMS EXCAVATING LANDSCAPING DEMOLITION Companies, Inc. 13792 247th Avenue – Zimmerman, MN 55398 Phone (763) 274-0925 Fax (763) 274-0928 2 | P a g e Wastewater Sources & Flows The new Chapel is expected to have a seat capacity for 80 guests with 2 employees on staff full-time. The estimated Peak Flow rate is 350 gallons per day (gpd) was calculated using values provided by Chapter 7081.0130, Table I: Estimate design sewage flow from other establishments. A safety factor of 20% was applied to calculate the final Design Peak Flow of 400 gpd. The Organic Load was calculated using the Estimate of Waste Strengths from Other Establishments chart provided with the University of Minnesota – SSTS Design Forms Worksheet (see U of MN Design Forms).The total Organic Loading Rate for 400 gpd for 80 guests (.01 #s / seat) & 2 full-time employees (.05 #s /employee) is .90 pounds of BOD per day which will need to be treated each day. This equals 269 mg/L of BOD per day. If the system was used to max capacity each day, this level of effluent would be considered At-Risk Effluent and might need to be sampled regularly to ensure treatment level C prior to dispersal to the Mound. However, the Septic Tanks, the Dose Tank & Soil Treatment Area have been designed to handle the worst-case scenario flow-rate & waste-strength from this building The septic tanks & dose tank are sized to provide a retention time of 5 days (typical is 3-days retention) & a storage capacity of 2 x Peak Flow in the event of unexpected pump failure. The total size of the Soil Absorption Area was increased 25% to account for a potential of At-Risk Organic Loading rates of BOD & TSS. The Peak Design Flow rate of 400 gpd for a typical Type I system receiving Residential Strength Waste (170 mg/L BOD) would require 1,040 sqft of absorption in Silt Loam soil. The increased size was calculated using the University of Minnesota Chart (Table 5.1; Manual for Septic System Professionals in Minnesota) for determining Organic Loading Rate. The equivalent loading rate for Silt Loam is 0.0007 #/sqft. The required absorption for .90 #s/day BOD @ 400 gpd with an Organic Loading rate of .0007 #/sqft is 1,280 sqft. Type I Mound The total area for the STA will impact 3,837 sqft (45.3’ x 84.7’) located to the South of the new Chapel. The newly constructed mound will have an Absorption Area of 1,300 sqft (26’ x 50’). The observations found redoximorphic soil conditions at 14 inches from the surface and will require 22” of washed- mound sand to achieve the necessary vertical separation from the most limiting layer. The required materials for the sewer line, distribution network, pumps, piping, sand, rock, fill and cover are detailed in the design worksheets included with this design. Please note, all calculations for materials and pumps are estimates. Actual values may change slightly and will need to field verified for correctness. See U of MN Worksheets for more details. The pump used for dosing the pressure bed must deliver a minimum of 22 gallons per minute and overcome a total dynamic head pressure of 16 feet. All supply pipes and laterals shall be built to specifications and drain-out completely after each dose to prevent freezing. A second 1,300 sqft area was identified and staked-off for future use. No structures or vehicle traffic can occur over this area. Precautions should be taken in the years to come to avoid damaging, compacting or disturbing this area. Special Conditions 1. Due to the large flat area, drainage should be maintained throughout the area to avoid ponding around the tanks or at the edges of the Mound. 2. No final sewer elevation was provided by the builder. Elevation and locations are subject to change. No tank can be buried deeper than 4’ below grade. 3 | P a g e 3. Drainback for Supply Line & Freezing - The slope from the Pressure Bed Supply Line must drain back to the dose tank. Additional depth or insulation may be necessary to keep line from freezing if the supply line is buried too shallow. 4. Setbacks to Easements & Property Lines –There was no survey performed prior to site evaluation, so all measures are estimates. The owner and Installer will need to make sure all construction is within required setbacks. Other Considerations 6.1 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.9.11 Site Protection 9.11 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. 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 End of Report Disclaimer As property owner, I agree to use the system within the parameters described above and in the design worksheets. I also agree hold Steinbrecher Companies, Inc and the named designer harmless for any future issues regarding this system.

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! Property Owner Email Property Address Property ID System Designer Contact Info System Installer Contact Info Service Provider/Maintainer Contact Info Permitting Authority Contact Info Permit # Date Inspected Keep this Management Plan with your Septic System Owner’s Guide.

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 ofa 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. 36 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: 80 On Demand 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.
