Town of Branford

The Town of Branford, FL, was experiencing loss of detention volume and reduced water quality as a result of accumulated sand and grit on the bottom of their aeration basin and digester. The roughly 200,000 gallon per day facility had a large quantity of sand submerged under water. The accumulated sand and grit had reduced the efficiency of the grit chamber and was potentially exposing other elements in the treatment system to a buildup of sediments and particulates.
