A sand filter septic system is one of the best ways to treat wastewater when traditional drain fields aren’t suitable. Instead of relying solely on soil absorption, sand filters provide an extra purification step by filtering effluent through layers of sand and gravel. This makes them a great choice for properties with high groundwater, shallow bedrock, or poor soil conditions. Whether you’re building a new septic system or upgrading an old one, installing a sand filter can extend the life of your system and improve environmental safety. Let’s explore how sand filters work, what to look for, and which products are worth considering.
