The Town of Derry’s Department of Public Works awarded a five‑year professional‑engineering services contract to Underwood Engineers for two major wastewater‑capital‑improvement projects. The scope includes design, permitting, cost estimating, construction‑phasing, and construction administration for a 3,525‑ft gravity sewer extension, a 2,000‑ft force‑main, a new lift station, and extensive lagoon‑based wastewater‑treatment‑plant upgrades. The work will be funded primarily through the New Hampshire State Revolving Fund, State Aid Grants, EPA grants, and local appropriations, with the engineering fees to be negotiated after award. • Project 1 – Route 28 (Ryan’s Hill) sewer main extension (~$7.1 M). • Project 2 – Wastewater‑treatment‑plant (WWTP) improvements (~$15 M). • Services cover full engineering lifecycle: studies, design, permitting, bidding documents, construction administration, and funding assistance.
