About the Linden Roselle Sewerage Authority

The LRSA services the City of Linden and the Borough of Roselle, and was established in 1948 to contract and operate wastewater treatment and interceptor facilities, as well as to collect, treat and dispose of sewage generated by the municipalities. The Authority’s service area is 13 square miles, it services a residential population of 60,000 and a diverse industrial community, and administers a state approved Industrial Pre-treatment Program.

The Authority’s sewerage treatment is classified as a biological system and is designed to treat 17 million gallons per day. It consists of primary sedimentation, activated sludge, secondary clarifiers and ultraviolet disinfection for final effluent. Residuals (sludge) treatment is by gravity thickening of primary sludge and gravity belt thickening for waste activated sludge, followed by anaerobic digestion. Sludge is transported via barge to a private dewatering facility where it is prepared for ultimate disposal at municipal landfills.

The Authority is governed by federal and state regulation. Our facilities operate and treated wastewater is discharged to the Arthur Kill under Permit # 0024953, issued by the N.J. Department of Environmental Protection. A portion of the effluent is permitted for beneficial reuse for cooling water for electric power generated at an adjacent power plant.

The Authority owns administration, monitoring, laboratory, treatment facilities and various auxiliary buildings at its primary site, located at 5005 South Wood Avenue, Linden, NJ, as well as a dock facility at the Arthur Kill and various metering pumping stations and pipelines outside the main facility.

LRSA was created under the “Sewerage Authorities Law”(N.J.S.A.40:14A-1et seq.) and is governed by the Members of the Board. Day to day operations and administration are conducted by a staff headed by an Executive Director.
