Terry & Son's Environmental Mobile Pumpout Service


Terry Durfee owns and operates Terry & Son's Environmental Mobile Pumpout Service (a not-for-profit company) on Lake Washington, Portage Bay east of the University Bridge and the Duwamish Waterway in King County.

Terry and Son's service is partially funded by a grant from the Sport Fish Restoration Fund administered by the U.S. Fish & Wildlife Service and Washington State Parks Clean Vessel Act Program. The rest of the funding for keeping this service available is from donations, without which the service would not exist.

Pumpouts are free to recreational boats by scheduled appointment by calling (206) 437-6764 or you can request a pumpout online at  PumpOut.Me 

Please note: PumpMeOut.com is a commercial pumpout service not Terry & Son's
