Assuming that locations with suitable hydraulic conditions are used and that the flow monitors have been properly installed, diligence is required to assure data quality over the full monitoring period. Routine data review is one key aspect. You must keep track of the ƒ pulseƒ of the data. At ADS, we use both automated reviews and human reviews for this purpose. The urban sewer environment is quite dynamic and can be quite hostile at times. As such, we remain on alert for changing hydraulic conditions and/or problems with monitoring equipment that may arise. Problems that are found quickly can often be resolved quickly, and that is our goal. Periodic field confirmations are also a routine practice and ensure that the measurements made by the monitors are reasonable.
