Gem Lake News Page 6 of 8 Keeping Your Septic System Healthy from the Minnesota Pollution Control Agency More than 600,000 Minnesota homes and businesses use septic systems, treating an estimated 42 billion gallons of wastewater per year. Maintaining these systems is critical to protecting our groundwater, lakes, and streams, as well as human health. A poorly functioning septic system may not remove pathogens, nutrients and other chemicals from the sewage. Understand Your system A septic system has three parts, all of which must be working to provide effective sewage treatment. These parts are: • Household plumbing • A tank to collect sewage and solids • A soil treatment area (also called a drain field) Maintain Your System Many septic system owners assume as long as their used water “goes away,” their system must be working properly. Septic systems must be designed specifically for your site’s conditions and installed correctly. Only regular maintenance and evaluation of the system can ensure that it is actually treating your sewage. Look for signs of a faulty or poorly functioning septic system. These include a pipe that goes directly to the lake or ground (even laundry water!), sewage surfacing in the yard or a ditch, sewage odors, high levels of nitrates or cold form bacteria in well water tests, or algae blooms and excessive plant growth in nearby ponds or lakes. Septic system maintenance will increase system life. The MPCA suggests that septic tanks be evaluated at least every three years and pumped out when sludge and scum accumulate to the point of endangering the soil treatment system. For some homes, the accumulation can take many years; in other homes this process may take less than a year. The accumulation depends entirely on how the system is used. For example, routine garbage disposal use will increase accumulation of material in the tank. Septic tank additives are not an alternative to pumping the accumulated solids from the tank.

If you have periods of high use, talk to a septic professional about options that will help your system manage your lifestyle. • Minimize use of harsh cleaners, bleach, antibacterial soaps and detergents. • Do not dispose of paints, medications or chemicals through your septic system. • Keep grease, lint, food and feminine hygiene products and plastics out of the system. Septic Tank • Pump solids through tank’s maintenance hole regularly, at least every three years. • Do not remove solids through inspection pipes. • Install and insulate risers to maintenance hold for improved management access. • Have baggies inspected when tank is pumped. • Install an effluent screen and service as necessary • Do not use tank additives or cleaners. Soil treatment Area • Maintain grass, native grasses or flowers over the treatment area. Mow, but do not fertilize, water or burn the area. • Do not plant trees, shrubs or deep-rooted plants on or near the area. • Do not grow vegetables or locate playgrounds above the area. • Keep heavy vehicles off area. (Such as cars, tractors, snowmobiles or boats) • Help prevent the system from freezing.
