Across Arkansas, homeowners are taking a closer look at septic system safety after new guidance warned of serious risks associated with covering leach fields with concrete.
New advice from the City of Bella Vista, Arkansas, urges property owners to protect their septic drain fields by avoiding heavy loads, concrete, and invasive landscaping that can damage the system, helping to prevent costly failures and environmental contamination.
Guidance on Protecting Septic Drain Fields
The drain field, also known as a leach field, consists of multiple porous lines buried a short distance beneath the yard’s surface. It receives filtered wastewater from the septic tank and disperses it into the surrounding soil. This process naturally removes harmful bacteria before the water reaches groundwater.
After solids settle in the septic tank, the liquid effluent exits through the leach lines. The soil’s filtration action further cleans the water, allowing it to be safely absorbed. Proper functioning relies on the soil’s ability to exchange oxygen and moisture.
Home improvement projects such as building pools, workshops, or expanding decks can threaten a drain field if the location is not considered. Vehicles can crush the porous lines, and digging may accidentally strike them. Planting trees nearby poses a risk as roots can infiltrate and damage the system.
Concrete and other impermeable materials should never be placed on top of leach lines because they block essential oxygen flow. Homeowners are advised to shield their fields and follow EPA recommendations for septic care. The City of Bella Vista, Arkansas, provides these guidelines to help protect both property owners and the environment.
