Solid and Liquid Waste Disposal

The City of Seattle is soliciting sealed bids under ITB SU0-6802 for a pool of vendors to manage, process, transport, and dispose of nonhazardous solid and liquid waste, with a non-mandatory pre-bid conference on October 27, 2026 and bids due November 23, 2026. The source sets no set-aside, preference, or minimum qualification for bid eligibility.

The scope covers nine waste streams, including street maintenance debris, hydroexcavation waste, contaminated rubble, soils, organics, treated wood, sewer solids, oily water, and drinking water treatment residuals. Delivery methods include dump trucks, vactor trucks, eductor trucks, sealed roll-off containers, and supersacks, with quantities from individual tons to 10-plus cubic yard bulk loads. Vendors must provide an order desk open 7:00 AM to 5:00 PM on business days, maintain inventory for same-day response on frequently ordered items, and offer two business days' response time for most new orders. Pricing is submitted as unit prices per ton, cubic yard, gallon, or bulk quantity and must include labor, equipment, transportation, processing, and facility access, excluding sales tax. Bid Form 2 offers optional pricing for vendor-provided transportation and container rental. Vendors must hold Seattle Business Licenses and Washington State business licenses.

Primary users are Seattle Public Utilities, Seattle Department of Transportation, and Seattle City Light, though any City department may use the contracts. The term is five years with one two-year extension at the City's discretion. Average annual usage across current contracts is $3.05 million, with average orders of $6,000 and some reaching $20,000. The City does not guarantee utilization and reserves the right to make multiple or partial awards, re-solicit, or use supplemental contracts. Every award carries a 90-day trial period with immediate cancellation possible for non-performance. Invoices are net 30 days after acceptance, and no minimum order quantities or advance payments apply.

The source lists King County and Spokane City as jurisdictions. The City currently holds contracts with Waste Management (contract 3700) and Ventilation Power Cleaning (contract 3758), which close when new contracts are established. Vendor questions are due November 6, 2026 at 5:00 PM, and sealed bids are due November 23, 2026 at 10:00 AM through the City's OpenGov portal.
