BOARD/COMMISSION REVIEW:

BACKGROUND:
There are currently three existing meters to measure flow from the influent pump station to the north and south plants at Springbrook. Measurement of flow is required as part of the City's National Pollutant Discharge Elimination System (NPDES) permit compliance. The existing flow meters are approximately 22 years old and have reached the end of their useful life.
