Sand Filter O&M Agreement

A sand filter is a device that allows stormwater to percolate down through a sand media where pollutants are filtered out.

Sand filters are designed primarily for water quality enhancement; flow volume control is typically a secondary consideration.  They are generally applied to land uses with a large fraction of imprevious surface.  Although an indivudual sand filter can only handle a small contributing drainage basin, multiple units can be dispersed thoughout a large site.
