Re: Hydraulic Needs Assessment and Evaluation of the Nashua Wastewater Treatment Facility
RFQ0265-060316
Dear Mr. Keating:
Woodard & Curran is pleased fo offer fhe following scope of work fo provide the City of Nashua (Client)
a Hydraulic Needs Assessment and Evaluation at the Nashua Wastewater Treatment Facility. The
Standard Terms and Conditions previously approved by the Client shall become part of this letter
Agreement.
Background
The Nashua Wastewater Treatment Facility's potable water booster system is in need of upgrades.
The original intent was to demolish the existing infrastructure and design an above ground station. The
modifications would ensure the proper operation of back flow preventers, eliminate enclosed space
entry requirements and maintain redundancy to the plant’s process water system. After discussion with
the staff on Monday, June 26'", it appears that critical elements of this project may be achieved with
alternative solutions. One option is to provide an interconnection between the potable water and the
process water systems and relocate the pumps and back flow preventers into the Control Building if
space fs available. Further investigation is needed but Woodard & Curran believes this effort will result
in a better, long ferm solution. This Hydraulic Needs Assessment and Evaluation will focus on the
plant’s potable and process water needs, historical flows, plant piping and footprint availability, which
will ultimately better define the design project. By executing this evaluation with Woodard & Curran, the
Wastewater Treatment Facility staff will have a current, comprehensive understanding of the needs and
the best solutions for this project. All the information collected and hydraulic engineering performed will
be incorporated into the next phase.
Scope of Services
Woodard & Curran shall perform the following tasks as part of this project.
1. Hold a Project Kickoff Meeting and perform a site walkthrough with the City to gain a
comprehensive understanding of the hydraulic needs and existing conditions of the potable
waiter supply to the plant. Discuss parameters such as:
a. Existing condition of potable feed water main and valving.
b. Current potable water uses throughout the plant.
c. Backup use of the potable water line for plant processing.
d. Potable water flow data and fire protection needs.
2. Collect and review water data and background information for the project including but not
limited to:
