Homeowners reminded to maintain septic systems

The Wisconsin Department of Safety and Professional Services, and the U.S. Environmental Protection Agency, are teaming up to present Septic Smart Week 2021, an annual event focused on educating homeowners on the proper care and maintenance of their septic system. This year’s awareness week runs from Sept. 20-24.

About one third of Wisconsin’s population uses onsite wastewater treatment, otherwise known as septic systems. This includes around two million people and over 750,000 households.

Onsite systems provide a sustainable, dependable and affordable method for wastewater treatment. Not only does treatment of wastewater through the soil protect groundwater resources, but it also keeps the water within the watershed.

When properly installed and maintained, these systems help protect public health, preserve valuable water quality and help ensure a community’s economic vitality.

Failing septic systems can contaminate and harm human health and the environment by releasing bacteria, viruses and household toxics, to ground and surface water resources. Homeowners should have their system inspected every three years, by a qualified professional. Advanced treatment units need inspection more frequently.

Avoid pouring fats, grease and solids down the drain. These substances can clog a system’s pipes and drainfield. Only put things in the drain or toilet that belong there. For example, flushable wipes, coffee grounds, dental floss, disposable diapers, feminine hygiene products, cigarette butts and cat litter, can all clog and potentially damage septic systems.

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’t been pumped recently.

Remind guests not to park or drive on a system’s drainfi eld, where the vehicle’s weight could damage buried pipes or disrupt underground flow. Routinely pumping the tank can prevent the septic system from premature failure, which can lead to groundwater contamination. Tanks should be pumped when necessary, typically every three to five years.

If septic systems aren’t properly maintained, leaks can contaminate well water. Testing a drinking water well is the best way to ensure the well water is free from contaminates.
