Sewer Department

The primary objective of the Sewer Department is to protect the safety and health of the public and to safeguard the environment through proper operation and maintenance of the municipal wastewater collection system. 

The Sewer Department carries out the will of Council, as promulgated by Municipal Code, Ordinances, and Resolutions of Council. Sewer Department staff are employees of the Municipality. The Sewer Operating Committee (SOC) is a separate entity which serves in an advisory role to Council. SOC members serve on a volunteer basis. The SOC discusses municipal operations, identifies issues suitable for Council review, gathers and evaluates information, and recommends courses of action to Council. To learn more about the SOC, and to view upcoming meetings, visit the Sewer Operating Committee page.

The Municipality owns the public wastewater collection system (sewer) in Princeton, which the Sewer Department is responsible for operating and maintaining. All of the wastewater that's produced in Princeton is treated at the River Road Wastewater Treatment Plant, located off River Road. The Municipality does not own the River Road facility, so the Sewer Department is not involved in the operation or maintenance of that facility. The River Road facility, which also receives sewage from South Brunswick Township and West Windsor Township is owned and operated by the Stoney Brook Regional Sewerage Authority (SBRSA) . The SBRSA is a joint municipal organization which operates three (3) sewage treatment facilities serving Hopewell Borough, Hopewell Township, Pennington Borough, South Brunswick Township, The Municipality of Princeton, and West Windsor Township. For more information about the SBRSA, or to report odors from the River Road facility, please visit the SBRSA website.
