Wet Weather Influent Screening Upgrade

To approve the contract with Waterline Industnes Corporation of Seabrook, NH in an
amount of $1,237,677 for replacing the screen and rakes in the Wet Weather Facility.
Funding will be through: Department: 169- Wastewater; Fund: Wastewater: Activity:
Wet Weather Facility Influent Screening Upgrade.

The Wet Weather Facility located at 2 Sawmill Road in Nashua is designed to treat flows
at the wastewater facility above 50 million gallons per day. Over the years, the facility
has experience issues with its two influent screens. Parts of the screen fields have
become bowed allowing large material to pass through and clog pumps within the Wet
Weather Facility. Another issue is that the rake mechanisms do not remove debris
properly from the screen field allowing flow to back-up into the interceptor creating other
issues and causing the Wet Weather Facility to be ineffective. Several interim solutions
have been tried to correct the issues with little success.

The Wet Weather Facility screens and rakes need to be replaced in order for the facility
to operate correctly. In addition to this project, other upgrades include: improving above
ground access hatches, installing access ladders partially down each screen vault and
installing hoists at the wet well to aid in the maintenance of the lower portion of the
screening units.

This project went out to bid on September 26th. Two bids were received at the bid
opening on October 28th: TBuck in the amount of $1,728,507 and Waterline Industries in
the amount of $1,237,677.

References provided by Waterline Industries were checked by consultant Wright Pierce
and all were favorable. Wright Pierce also provided a recommendation to award the
project to Waterline Industries.

BID SET No.
