About us
Washington Stormwater provides chitosan-enhanced sand filtration (CESF) units for construction, industrial, & heavy civil construction projects throughout Washington to lower your project costs and improve site safety. Our innovative, self-contained units use biodegradable chitosan (derived from crab shells) to filter contaminants from construction site runoff, so it's safe to re-enter the environment.
