How to bid on solid and liquid waste disposal for the City of Seattle
What Seattle is buying
The City of Seattle seeks qualified vendors to handle assorted nonhazardous solid and liquid waste on an as-needed basis. Services may include receiving, sorting, treating, transporting, reusing, or disposing of materials, along with container rental and service.
Work may take place across Seattle and at project locations elsewhere in Washington. Combined past annual use was about $3.05 million, with typical orders around $6,000 and some as high as $20,000. These figures describe past use, not guaranteed work.
Deadline and timing
The IFB was published October 9, 2026. Responses are due November 23, 2026, at 1:00 PM ET.
Submit through OpenGov before the deadline. The solicitation information provided does not state what happens to responses received after that time, so plan to complete submission early.
Who this opportunity may suit
This opportunity may suit environmental services firms equipped to manage nonhazardous waste streams and provide related processing, transport, reuse, or disposal services. Relevant capabilities may include container rental, facility operations, waste acceptance, and documentation.
The City names materials such as street maintenance debris, hydroexcavation waste, contaminated rubble, soils, organics, treated wood, sewer solids, oily water, and drinking water treatment residuals. Vendors should assess which of these services they can provide and whether they can support work across Seattle and statewide project locations.
