City of Nashua, Public Works Division
Board of Public Works Meeting Date: May 23, 2019
David L. Boucher, Superintendent
Wastewater Department
Combined Sewer Overflow Flow Monitoring Program
To approve Amendment No.2 in the amount of $56,100 to the contract with Fiow
Assessment of Auburn, NH for the Combined Sewer Overflow Monitoring Program.
Funding will be through Department: 169 - Wastewater; Fund: Wastewater; Account
Classification: 53 Professional Services.
Flow Assessment Cost Proposal
The Combined Sewer Gverfiow (CSO) Monitcring Program monitors flow at all of
the CSC discharge structures and three rain gauges throughout the City. The data
collected provides information for reporting to the USEPA and the NH Depi. of
Environmental Services as required vy the National Pollutant Discharge Elimination
System (NPDES) permit for the Wastewater Treatment Facility.
The current contract with Flow Assessment is scheduled to end on June 30, 2019.
They have provided excellent reporting and a user friend web site. Their equipment
is already in place and will remain so until the new contract starts. It is beneficial to
the City to continue with this service provider due as there are not many service
providers in this field and we have not been successful with a past service provider.
Hence it is recommended that they be awarded a new one-year contract. The total
cost for monitoring ail the CSO sites is $56,100, which is the same as last year’s
costs.
