Specifications include, but are not limited to: The City of Seattle through the Seattle Public Utilities (SPU) is seeking proposals for remote settlement monitoring services using Interferometric Synthetic Aperture Radar (InSAR) satellite mapping. The Ship Canal Water Quality Project (SCWQP) is seeking these services specifically from 2019 to the end of 2026 for the 2.7-mile-long Storage Tunnel Project which extends from the Ballard neighborhood east to the Wallingford neighborhood. SPU and the King County Department of Natural Resources and Parks (DNRP) are working together to build an underground storage tunnel to reduce the amount of sewage and stormwater (combined sewage) that discharges into the Lake Washington Ship Canal (Ship Canal) from Ballard, Fremont, Wallingford, and north Queen Anne neighborhoods. During storms that exceed the capacity of the wastewater system, combined sewage flows from these areas currently discharge into the Lake Washington Ship Canal without treatment. These discharges are referred to as combined sewer overflows (CSOs). The Ship Canal Water Quality Project will convey the excess flows to a large underground storage tunnel, which would store the flows until they can be conveyed to the existing West Point Wastewater Treatment Plant in Magnolia. The proposed facilities will be owned and operated by SPU.
