SECTION 1 – INTRODUCTION

1.1 Intent

The Town of Derry, New Hampshire, through its Department of Public Works (DPW), is

soliciting Statements of Qualifications (SOQs) and Requests for Proposals (RFPs) from

qualified professional engineering firms to provide planning, design, permitting, bidding,

and construction-phase services for upcoming wastewater infrastructure projects.

The Town intends to use this qualifications-based solicitation to select one or more

engineering firms with demonstrated expertise in municipal wastewater systems. The

selected firm(s) may be engaged under contract to provide professional engineering

services for the following priority projects:

• Route 28 (Ryan’s Hill) Sewer Main Extension Project:

This project will extend the Town’s municipal sewer system along Route 28

(Rockingham Road) from its current terminus at Berry Road southerly to the area

known as Ryan’s Hill. The work includes construction of approximately 3,525 feet of

15-inch gravity sewer and 2,000 feet of 6-inch force main sewer, as well as a new

sewer lift station.

The project is currently estimated at $7.1 million and will be funded through a

combination of NH DES State Revolving Fund (SRF), State Aid Grants (SAG), an EPA

Congressionally Directed Spending grant, and local appropriations. Design is

anticipated in 2026, with bidding targeted for late 2026 or early 2027.

• Wastewater Treatment Plant (WWTP) Improvements Project:

This project consists of a comprehensive rehabilitation and upgrade of the Town’s

4.0 MGD Wastewater Treatment Facility located off Transfer Lane. Work includes

replacement of the Hypalon/HDPE liners in the three treatment lagoons;

replacement of the aeration systems in two of the lagoons; removal and off-site

disposal of approximately 1,200 dry tons of sludge; and restoration of Lagoon 3 to

service, including installation of new aeration diffusers. New bypass yard piping

may also be required to maintain plant operations and treatment capacity while

individual lagoons are taken offline during construction.

The estimated project cost is $15 million and will be funded through a combination

of NH DES State Revolving Fund (SRF), State Aid Grants (SAG), and local

appropriations. The Town has been approved for a $300,000 Clean Water SRF loan

to support reengineering efforts. Design engineering is anticipated in 2026–2027,

with bidding targeted for late 2027. The project will likely be delivered through

multiple construction contracts.

1.2 Background

The Town of Derry owns, operates, and maintains municipal wastewater collection and

treatment infrastructure serving residential, commercial, and industrial customers.

The system is comprised of over 3,100 sewer services connections and approximately 53

miles of gravity sewer, 8 wastewater pumping stations, 1 effluent booster pump station,

and 10 miles of force main.

The Town of Derry, NH owns and operates an aerated/facultative lagoon wastewater

treatment plant (WWTP) that was constructed in the 1980’s with a permitted capacity of

4.0 MGD. The facility consists of three lined lagoons each having approximate liquid

depths of 18 to 20-feet. Currently, the facility only operates on Lagoons 1 and 2. Lagoon 3

is offline but was drained, cleaned, and had its liner replaced in 2003. The WWTP also

consists of a headworks, influent pump station, blower building, and effluent pump

station. There is also a fourth unaerated polishing pond that acts as a large wet well for the

effluent pump station.

Continued growth, aging infrastructure, and evolving regulatory requirements necessitate

strategic investment in system upgrades, expansion, and capacity improvements. A

comprehensive Wastewater Master Plan was conducted in 2023 which identified the

system improvement needs.
