Stormwater Treatment: Assessment and Maintenance
(click here for online manual)

The University of Minnesota (U of M) in partnership with the Minnesota Pollution Control Agency (MPCA) has produced a new (March 2010) online manual for assessment and maintenance of stormwater treatment practices. The manual provides guidance on applying the "Four Levels of Assessment":

1. Visual Inspection
2. Capacity Testing
3. Synthetic Runoff Testing
4. Monitoring

Maintenance is vital for effective stormwater treatment. The manual also provides guidance on selecting and scheduling maintenance activities.
