Flow monitoring is a critical step in analyzing a sanitary sewer system, whether it is for sanitary sewer evaluation surveys (SSES), calibrating hydraulic models or sizing system upgrades. However, given the number of flow meter types and manufacturers available combined with differing system conditions (i.e. depth of flow, velocity, slope, pipe type, etc.), obtaining reliable data is difficult if the correct techniques are not utilized. To compound this problem, the introduction of CMOM-related language in recent consent orders is dictating strict reliability requirements with the consequence of continued metering if requirements are not met. As such, if reliable flow monitoring data is not collected, costs associated with metering projects can increase substantially.
