Underground devices remove trash and pollutants before discharging water back into Artesian Creek
A trash capture device works underground to remove approximately 1,000 gallons of trash from entering local waterways per year.
An underground biofiltration system works to remove pollutants, particularly bacteria, from stormwater runoff.
The result is cleaner water discharged back into Artesian Creek, a tributary of the San Dieguito River.
The County of San Diego is proud to implement projects like this to improve water quality, support sustainability, and enhance our local communities.
