Information: We have created this new page called Infiltration, which includes information on infiltration trenches, infiltration basins, dry wells, and underground infiltration practices. This page and the accompanying pages shown below replace the Infiltration trench and Infiltration basin sections of the manual.
Infiltration basins, infiltration trenches, dry wells, and underground infiltration systems capture and temporarily store stormwater before allowing it to infiltrate into the soil. As the stormwater penetrates the underlying soil, chemical, biological and physical processes remove pollutants and delay peak stormwater flows.
These four practices are grouped together because design, construction, operation, and maintenance guidelines and specifications are similar. Differences between these practices, where they exist, are highlighted on each of the following pages. For additional information on other infiltration practices, see Stormwater infiltration Best Management Practices and Bioretention terminology.
