Combined Sewer Overflow Flow Monitoring Program

To approve Amendment No.1 in the amount of $56,100 to the contract with Flow
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 Overflow (CSO) Monitoring Program monitors flow at all of
the CSO discharge structures and three rain gauges throughout the City. The data
collected provides information for reporting to the USEPA and the NH Dept. of
Environmental Services as required by 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, 2018.
They have provided excellent reporting and a user friend web site. Their equipment
is already in place and will remain so till the new contract starts. It is beneficial to
the City to continue with this service provider, and hence are being given a new one-
year contract. The total cost for monitoring all the CSO sites is $56,100, which is at
the same monthly cost as their current contract.
