StormTrap provides underground storm water infiltration systems to meet your site’s individual needs. A storm water infiltration system differs from a detention solution as it allows the water to slowly discharge into the soil instead of detaining it for a time before it is released. This helps to avoid flooding and erosion. It also provides quality advantages because it filters the runoff water through the native soil to effectively reduce pollutants in the runoff, such as oil, grease, heavy metals and more.
