Bucket and sponge for cars
Use a bucket and sponge instead of a hose to wash your car and, where possible, wash your car on the lawn to prevent soapy water from entering the street drain and into streams and rivers.
Broom surfaces
Use a broom to sweep hard surfaces like paths and driveways instead of trying to hose down leaves and twigs.
