Why doesn the County install filters or screens in front of drain inlets?
It sounds like a good idea, but during a rainstorm, trash is quickly swept into drain inlets. Any screen or filtration device placed in front of the drain inlet would cause trash to accumulate and clog the grate, preventing proper drainage and potentially creating a flood hazard. With approximately 61,000 drain inlets in Sacramento County maintenance crews would be unable to keep up with cleaning these devices potentially creating flooding hazardous. However there new technologies being developed in the form of filtration or screening devices to be installed and inserted inside drain inlets. The Stormwater Program Engineering groups are always evaluating these new technologies for possible future use.
