Stormwater Mag has a new article on SWM Maintenance.  Maintenance of Stormwater BMPs | stormh2o.com.    Much to be said on this topic….  It is amazing that millions (billions???) of dollars of infrastructure goes in the ground and a small portion of it is maintained. …  which results in increased pollution.  It is the hidden pollution source of stormwater.  Of course, we are a bit jaded, ’cause SWMaintenance is one of the things we do.
