Seattle completed a tunnel that temporarily stores more than 112 million liters of stormwater and wastewater, with an estimated 284 million liters of contaminated water kept from local waterways each year. The completed project signals municipal demand for underground construction and climate-resilient water infrastructure, but the source identifies no active solicitation or contract value.
