Bilge Water

(Last Updated: 2/8/2021)

Bilge water is any liquid that did not drain off the sides of the boat and instead collected in the bilge. Bilge water may contain contaminants such as oil, diesel, gas, solvents, and particles. Contaminated bilge water should not be released into Puget Sound, rivers, lakes, streams, storm drains, or on the ground.

Small amounts: Soak up small amounts of bilge water with oil absorbent pads or socks (available at marine supply stores) and place them in a plastic bag. Tie the bag and place it in the garbage.
Large amounts or contaminated: If the bilge water is too contaminated or too difficult to clean up with absorbents, take the following steps:
  • If you have up to 10 gallons, take it to the Household Hazardous Waste (HHW) Collection Facility for free disposal. Package products carefully for transportation. See facility hours at the website below.
  • For 10 gallons or more, contact one of the private vendors listed below.
