BALDWINSVILLE-SENECA KNOLLS WASTEWATER
TREATMENT PLANT (WWTP)
The Baldwinsville-Seneca Knolls (BSK) WWTP construction was completed in 1982, replacing a number of treatment plants serving the towns and villages on both sides of the Seneca River. These older, deficient plants were converted to pump stations to convey the flow to the new advanced WWTP and thereby improve the water quality downstream. The BSK WWTP also allowed for more housing developments in the area with sewers and more pump stations. There are now 23 pump stations in Baldwinsville, Radisson, Seneca Knolls, Interstate Island, and River Mall serving 36,000 residents. The wastewater is essentially all residential, since the few businesses and industries are not significant water users. Improvements were made to the plant in 2002, and include variable-speed influent pumps, PLC process controllers, and an odor control system.
FACT SHEET: Baldwinsville-Seneca Knolls Wastewater
Treatment Plant (WWTP)
The Baldwinsville-Seneca Knolls Waste Water Treatment Plant is a 9 MGD design facility located in the Town of Lysander along the shore of the Seneca River. The influent flow averages 3 MGD, and undergoes preliminary, primary, and advanced secondary treatment. Pure oxygen generated onsite intensifies the activated sludge process, which consistently removes over 95% of the BOD and Suspended Solids. The addition of ferrous chloride affects the chemical precipitation of phosphorous, which is a very important nutrient to keep out of the receiving waters. The treatment process is enhanced further in the warm weather to include nitrification and seasonal disinfection. The biosolids generated are treated in pure oxygen aerobic digesters and dewatered by belt-presses prior to transportation to a landfill.
