Meadowbrook Limestone Wastewater Treatment Plant

(Effective beginning September 1, 2021 and expires on August 31, 2026)




MeadowBrook Limestone WWTP

Service Areas

Construction of the Meadowbrook-Limestone WWTP was completed in 1973. The facility has a design flow of 6.5 MGD and provides advanced secondary treatment of wastewater using an Extended Aeration Activated Sludge Process. Wastewater is collected throughout significant sections of the Towns of Dewitt and Manlius; along with smaller portions of the Town of Pompey and the City of Syracuse. Wastewater is collected from various neighborhoods and commercial properties and transported via a series of pumping stations and gravity trunk sewers to the Meadowbrook-Limestone WWTP. The 48” Meadowbrook Trunk Sewer and the 18” Fremont Trunk Sewer enters the property via gravity feed and combines at Manhole No.2, located off the Southeast corner of the Maintenance Garage. Wastewater influent is primarily from residential and commercial sources.

Treatment Process

The wastewater undergoes screening and grit removal in the Headworks Building, utilizing both a bar rack and a mechanical screen rake, followed by grit removal in an aerated grit head cell, which uses a EUTEK Systems, Inc., stacked tray vortex grit removal system. Wastewater is then pumped from the influent wet well into the flow distribution box, where the flow is evenly split between two (2) aeration tanks where the activated sludge treatment process occurs. Activated sludge is treated using the Extended Aeration Process, activated sludge flows through both aerated tanks in parallel. The treated wastewater then flows to the final clarifiers where settling occurs. Activated sludge collected in the clarifiers is recirculated to the aeration tanks and/or wasted to the aerobic digestion tank. Digested sludge is thickened using a rotary drum thickener, stored in a thickened sludge holding tank and hauled to the Metropolitan-Syracuse WWTP for further treatment. Effluent from the clarifiers flows to the chlorine contact tank for seasonal disinfection using sodium hypochlorite before discharge to Limestone Creek. Total Phosphorus is removed year round with the use of ferrous chloride. Wet Weather storage tank used for high flow events.
