David L. Boucher, Superintendent
Wastewater Department

20 Year Facility Study - Wastewater

To approve the contract to Wright Pierce to develop and prepare a 20 year Facility
Planning Study for the Wastewater Treatment Facility in an amount not to exceed
$300,000. Funding for this contract will be through Department: 169 Wastewater;
Fund: Wastewater; Activity: Facility Planning Study.

Wright Pierce Scope of Work and Fee Schedule

The Wastewater Treatment Facility is one of the City’s most valuable assets. It
still has original pipes and tanks online that were designed and installed back in
the 1950’s. The City continues to expand and the EPA regulations continue to get
stricter. This study will develop a better understanding of the financial needs of
the Facility in the future, as well as looking at potential design planning needs as
the City’s NPDES permit regulations and the City’s population evolves and
grows.

A request for qualifications was issued in October of 2019 and consultants were
chosen for interview on November 5, 2019 by the selection team. The selection
team, consisting of David Boucher, Superintendent, Noelle Osbome, Plant
Operations Supervisor, William Keating, Wastewater Engineer, Scott Law,
Wastewater Foreman, Matthew Cusato, Wastewater Foreman, and Lauren Byers,
Public Relations Administrator, chose Wright Pierce as the most qualified firm.
The Scope of Work and Fee schedule was submitted, discussed, and agreed upon
as attached.
