Bath is tackling a list of pump-station upgrades throughout the city to address aging wastewater infrastructure.

The Harward Street pump-station and interceptor (a large pipe that collects waste from smaller sewer lines and sends it to the wastewater facility) upgrade is $9.9 million, with approximately $4.4 million covered by grants and the rest through a sewer bond approved by the residents last year, according to Bath Public Works Director Chris Wallace.

“It’s an antiquated system that needs to be upgraded and upsized,” Wallace said. “There are a few areas in the city that we had some overflow problems, and [we] hope this will alleviate most of the problems.”

The Bath Public Works Department is looking to secure more easements from property owners before moving forward with construction. The schedule for the Harward Street interceptor upgrade will begin at the end of December, with an anticipated construction time of a year, Wallace said.

The designs for the Harward Street upgrades are complete, and the project has already gone out to bid. Crooker Construction submitted the lowest bid, according to the agenda of the City Council meeting held on Aug. 6.

Next on the list of wastewater upgrade projects will be the Hunt Street pump-station and force-main upgrade, with a total cost of $8.4 million. That construction is expected to begin in spring 2026, followed by the Commercial Street force-main project and pump-station upgrade with a total project cost of $9.4 million, Wallace said. Construction on the Commercial Street project is expected for spring 2026, possibly intersecting with the Hunt Street project.

A public notification will go out to Bath residents and property owners near the sites.

Other projects anticipated for spring 2026 are the Richardson Street wastewater-separation project for $2.6 million and the Farrin Street pump station at $1.7 million.
