Council weighs wastewater projects to prevent overflows and costly upgrades
Summary
Councilors heard proposals to upgrade pump stations, reduce sewer inflow and infiltration and extend the effluent outfall; staff said targeted projects could avoid a projected $100 million treatment‑plant upgrade and prevent beach and bay overflows.
Engineering and public‑works staff told council the bond could fund projects to reduce environmental risk and expensive downstream upgrades. Staff said the Nye Beach and Bayfront pump stations need capacity improvements to avoid overflows — "if there's an overflow at that station, it's got one place to go and that's to the beach," a presenter said — and estimated construction at about $3.6 million. A sewer inflow and infiltration (I&I) reduction program was presented as a cost‑effective alternative to a roughly $100 million treatment‑plant upgrade, with the I&I work estimated around $4.5 million for the bond period.
Other projects included relocating the cliff‑edge 55th Street pump station (design ~30%, est. $1.7M) to prevent service loss and ocean discharges, extending the effluent outfall to deeper water (estimated $5M for boring), and upgrading biosolids processing equipment (estimated ~$3M) to maintain regulatory compliance and operations. Staff emphasized these are multi‑year projects and that work will be sequenced by urgency and available funding rather than started all at once.
