A Treatment Works Approval (TWA) is required from the NJDEP Division of Water Quality and the Stony Brook Regional Sewerage Authority (SBRSA) prior to construction of a sewer extension. Even if a development does not otherwise meet the definition of a sewer extension, a TWA is required from the SBRSA for any development that will produce 2,000 gallons per day or more of sewage.
All TWA applications must be reviewed and approved by the Princeton Sewer Department before being submitted to the NJDEP and SBRSA . The NJDEP and SBRSA will not accept TWA applications that have not received Princeton Sewer Department approval.
Provide engineering and architectural plans in PDF. If the PDF is not digitally signed and sealed, provide a signed and sealed paper plan set in addition to the PDF. Plans must meet the requirements stated in N.J.A.C. 7:14A-23.4.
