Did you know that one in five of all American households depend on septic systems to treat their wastewater? If you\u2019re one of those households, you should know how to care for and maintain that system in order to not only avoid costly repairs but also to prevent pollution to local waterways and risks to public health and the environment.\r\nFailure to maintain a septic system can lead to back-ups and overflows. Faulty septic systems release bacteria, viruses and chemicals that can be toxic to local waterways. These pollutants can harm ecosystems by killing native fish and plants.\r\nThis week, Sept. 21-27, is the third annual SepticSmart Week - and it\u2019s the ideal time to learn about how to care for your septic system. The West Virginia Department of Environmental Protection is helping promote the U.S. Environmental Protection Agency program by sharing septic maintenance tips such as these:\r\n\u2022 Protect It and Inspect It: Homeowners should generally have their systems inspected every three years by licensed contractors, and have their tanks pumped when necessary. Many septic system failures occur during the winter holiday season. Therefore, DEP and EPA encourage homeowners to get their septic systems inspected and serviced now, before licensed inspectors\u2019 schedules fill up around the holidays.\r\n\u2022 Think at the Sink: Avoid pouring fats, grease and solids down the drain. These substances can clog a system\u2019s pipes and drainfield.\r\n\u2022 Don\u2019t Overload the Commode: Only put things down the drain or toilet that belong there. Items such as coffee grounds, dental floss, disposable diapers and wipes, feminine hygiene products, cigarette butts and cat litter can all clog and potentially damage septic systems.\r\n\u2022 Don\u2019t Strain Your Drain: Be water efficient and spread out water use. Fix plumbing leaks and install faucet aerators and water-efficient products. Spread out laundry and dishwasher loads throughout the day - too much water at once can overload a system that hasn\u2019t been pumped recently.\r\n\u2022 Shield Your Field: Remind guests not to park or drive on a system\u2019s drainfield, where the vehicle\u2019s weight could damage buried pipes or disrupt underground flow. Having the right landscaping on and around your system is also important. Tree and shrubbery roots can grow into the drain lines, clogging and breaking them, so grass and native vegetation are the best covers for your drainfield.\r\nEPA\u2019s SepticSmart program educates homeowners about proper septic system care and maintenance all year long. In addition, it serves as an online resource for industry practitioners, local governments and community organizations, providing access to tools to educate clients and residents.\r\nFor more information, visit the EPA\u2019s SepticSmart page: http:\/\/water.epa.gov\/infrastructure\/septic\/Septic-Smart-Week.cfm.\r\nFor more DEP news and information, go to www.dep.wv.gov.
