Eastern Wayne Sanitary District WTP No. 3 — 301 Rockford Church Road
Sludge Management Plan
The WTP treats well water via aeriation and filtration, using three 10' diameter greensand filters The
primary function of the aeriation is to oxidize the iron and manganese, which makes them easier to
remove from the water. The greensand filters remove the oxidized iron and manganese These
components are backwashed from the filters, and directed to the waste holding tanks
The waste holding tank is divided into two sides. Each side holds 47,695 gallons in a baffled tank. There
is an additional foot of freeboard above the normal high water level
Backwash of one filter includes 10 minutes of backwash at 945 gpm, and 5 minutes of rinse at 250 gpm.
The total wash per filter is 9,575 gallons/cycle/filter or 28,725 gallons/cycle for three filters. Typically,
the design assumes backwashing each filter one time per day Therefore, the discharge would be 28,725
gallons per day, say 30,000 gpd.
The backwash containing iron and manganese is allowed to settle in the backwash tanks. Typically,
decant from the waste tank is recycled, blended with raw well water, is treated again, and sent out into the
distribution system. The District must retain the NPDES Permit in case there becomes an issue regarding
recycling of the decanted backwash.
After decanting, the remaining iron and manganese settle in the tank These residuals are hauled away,
and land applied by Granville Farms, Inc every other year Granville Farms has amended their permit to
accommodate sludge from Eastern Wayne Water District's Water Treatment Plant No 3
