Abstract
The present invention consists of a self-contained insert that can be placed within a catch basin or manhole in a closed conveyance stormwater drainage system. The device provides a means for isolating the water entering a catch basin from flows from other catch basins such that flow rate and water quality for water entering the catch basin can be measured, without contamination from flows from other catch basins. The device enables the use of various types of flow rate meters for determining the quantity of water passing into the catch basin and provides a volume of water from which samples may be collected for analysis of pollutant mass loading rates.
