→Continuous Monitoring
==Continuous Monitoring==
==Continuous Monitoring==
Continuous monitoring is the most comprehensive approach to inspection of stormwater BMPs that can provide quantitative information about drainage and water treatment performance during actual storm events, which can be directly compared to design specifications and regulatory criteria to determine if it is functioning and performing as intended. Continuous monitoring is the most costly and time-consuming approach to inspection, but warranted in certain situations.
At a minimum, continuous monitoring should be undertaken as part of Assumption and Verification inspections in the following situations:
#For infiltration BMPs designed without sub-drains to determine active sub-surface water storage reservoir volume drainage time and filter bed surface infiltration rate.
#For infiltration BMPs designed with flow-restricted sub-drains, to determine sub-drain peak flow rate, active sub-surface water storage reservoir volume drainage time and filter bed surface infiltration rate.
# As part of Forensic inspection and Testing (FIT) work to determine corrective actions for suspected problems with drainage or effluent quality detected through other inspection and testing work.
# When little information is available about the effectiveness of a certain type of BMP in a certain environmental context, or when a new technology is being implemented for the first time in a certain context or geographic region.
# Where the sensitivity of the receiving water warrants a high level of inspection and testing to determine if BMP effluent quality meets design specifications or regulatory criteria.
