Document Description
The proposed on-site treatment plant improvements include: the addition of an improved screening unit at the headworks, construction of a biological selector, optimization of the existing secondary clarifier, construction of another secondary clarifier, conversion of the existing return activated sludge (RAS) pump station to an aerobic digester, construction of a new RAS pump station, and improvements to an existing pump station to convey flows to the constructed wetlands area. The proposed off-site improvements include: installation of +/- 12,00 lineal feet of underground reclaimed-water pipeline within existing roadways and across undeveloped parcels, and construction of a +/- 77-acre wetland area to allow for the biological uptake of nutrients and percolation if reclaimed water.
