Richmond says no sewer capacity; Lewiston outlines plan for sewer storage and lift-station work
Summary
After receiving a formal denial from Richmond for sewer capacity, Lewiston council members described a local plan to expand sewer storage, build a new cell with roughly 19 million gallons of capacity and commence lift-station work this spring.
Lewiston City Council discussed sewer improvements after the city received official notice from Richmond that Richmond cannot accommodate additional sewer connections for several years. Council and staff described a local plan to increase Lewiston’s sewer capacity, including a large storage cell and lift-station work scheduled to begin in March.
Richmond denial and context
The mayor reported the city received a letter from Richmond advising that Richmond cannot accept additional flow into its sewer system; Richmond estimates it will be seven to ten years before it can increase capacity. Council said Richmond’s existing approvals and recently permitted homes in Richmond consume available capacity.
Lewiston’s response and proposed work
City staff told the council they will proceed with their own upgrades. Public Works staff said a lift-station project is scheduled to begin in March with a planned completion in May or early June, subject to construction schedule variability. Separately, staff and council described a larger storage-cell project; engineering calculations presented to council indicated the city needs to provide storage on the order of millions of gallons — the mayor and staff referred to about 19,000,000 gallons of storage capacity as their planning target.
Why it matters: denial of regional sewer capacity can limit growth and requires a municipality to provide local infrastructure or negotiate alternative arrangements. Lewiston’s plan for storage and lift-station upgrades is a substantive capital and engineering undertaking with permitting, easement and funding implications.
Next steps and implementation risks
Council said they will seek site visits and easement assistance and may engage outside engineers (the mayor mentioned working with regional staff such as Seth Tate). Staff will prepare more detailed plans and timelines for council review; councilmembers noted substantial work remains to secure land, design the storage cell and complete required construction. No final funding source or contract award was approved at the meeting.
