The dye dilution testing services will be the focus of this contract, which has been routinely performed on the sewer meters in the Greater Detroit Regional Sewer System (GDRSS) since 1996. There are a total of 54 sewer metering sites in the GDRSS. These meters are part of the ongoing meter accuracy verification program established by GLWA as part of "Good Metering Practices" program. The meter verification program provides periodic and independent review of meter performance to assess accuracy of operation. The independent flow checking method selected by Wastewater Analytical Task Force (WATF) is dye dilution testing. The dye dilution testing protocols were developed by the GDRSS project team with assistance from WATF, previously known as Flow Metering Task Force.
Dye dilution testing has been found to provide a consistent standard by which all metering accuracy can be assessed. The selected method involves ...
