EPA’s 14th SepticSmart Week: System maintenance protects public health, reduces costs

The U.S. Environmental Protection Agency on Monday launched SepticSmart Week 2026, a nationwide effort to help homeowners properly maintain their septic systems to protect public health, groundwater, local waterways, and the environment while saving families money.

More than one in five homes across the country relies on septic systems to safely manage wastewater. That number is even higher in rural and suburban communities, said Jess Kramer, EPA assistant administrator for water.

Failure to maintain a septic system can lead to sewage backups, contamination of drinking water, expensive repairs, and environmental damage. Regular inspections and preventive maintenance are often less costly than replacing a failed system.

The program provides homeowners, local governments, and community organizations with resources and tools to strengthen understanding of how septic systems work and how routine maintenance protects public health while reducing repair costs and extending system life.

Helpful tips:

• Think at the sink: What goes down the drain has a big impact on your septic system. Fats, grease and solids can clog a system’s pipes and drain field.
• Don’t overload the commode: A toilet is not a trash can. Disposable diapers and wipes, feminine hygiene products, coffee grounds, cigarette butts and cat litter can damage a septic system.
• Don’t strain your drain: Use water efficiently and stagger use of water-based appliances. Too much water use at once can overload a system that hasn’t been pumped recently.
• Shield your field: Tree and shrub roots, cars and livestock can damage your septic drain field.
• Keep it clean: Contamination can occur when a septic system leaks from improper maintenance. Test your drinking water regularly.
• Protect and inspect: Regular septic system maintenance protects public and can save homeowners thousands of dollars in repairs.
• Pump your tank: Ensure your septic tank is pumped at regular intervals as recommended by a professional and/or local permitting authority.
