Noelle Osborne, Plant Operations Supervisor
Wastewater Department
Flow Assessment Flow Monitoring Services
To approve the 6 month agreement with Flow Assessment Services of Goffstown,
NH for CSO Flow Monitoring and Alarming in the amount of $37,400. Funding
will be through: Department: 169 Wastewater; Fund: Wastewater; Account
Category: 55 Other Services.
Vendor Quote
The Combined Sewer Overflow (CSO) Monitoring Program consists of a full and
comprehensive program for monitoring flow at all nine of the CSO discharge
structures and three rain gauges throughout the City and provides information for
reporting to the USEPA and the NH Dept. of Environmental Services (NHDES).
This reporting is required by the National Pollutant Discharge Elimination System
(NPDES) permit for the Wastewater Treatment Facility. The data will further
assist in indicating the benefit to the receiving waters (Nashua and Merrimack
Rivers) due to the completion of the City’s CSO Consent Decree projects.
The installation of monitors will allow for data to be collected as wet weather
occurs (“real-time”) so that web-based reports of flow and rainfall data can be
generated. They will also provide the City with information regarding dry
weather flows. Work includes supply of equipment, installation and monthly
maintenance and reporting.
The current vendor contract has not provided the Facility with the quality of data
necessary to fulfill the reporting requirements to the USEPA and the NHDES.
The City has an established history with Flow Assessment and has had positive
results and good, reliable data. This request is to establish services until the end of
the Fiscal Year at a cost of $37,400.
