Mt. Dora, FL

In total, approximately 630-tons of material was removed from these two structures and disposed of off-site, restoring capacity, efficiency, and flow to the City’s treatment plant. By restoring capacity USST estimates the City saved over $1.5 million in capital expense to rebuild the treatment capacity. In other words, the cost of maintaining existing treatment volume is much less than re-building the oxidation ditches treatment volume.

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.
