Bilge Water

(Last Updated: 7/14/2023)

Special Handling for Disposal

Bilge water is liquid that has collected in the bilge rather than drained off the side of the boat. Bilge water is usually contaminated with oil, diesel, gas, solvents, or particles. Contaminated bilge water should not be released into Puget Sound, rivers, lakes, streams, storm drains, or on the ground.
