Treatment Works Approvals
The Treatment Works Approval (TWA) program regulates the construction and operation of industrial and domestic wastewater collection, conveyance and treatment facilities, including treatment plants, pumping stations, interceptors, sewer mains and other collection, holding and conveyance systems. The program is aimed at protecting the waters of the state by preventing the entry of increased pollutants from inadequate facilities. The administrative and technical requirements of the TWA program are stipulated in N.J.A.C. 7:14A-22 and 23, respectively.
Treatment Works Approvals are a type of construction permit wherein the division evaluates the proposed treatment plant's design and its ability
to meet the effluent standards specified in the NJPDES permit.
They are issued after a discharger has obtained a NJPDES permit.
The Treatment Works Approval process also involves assessing the design of new sewer lines and other wastewater conveyance facilities (force mains, pumping
stations, etc.) as well as evaluating downstream conveyance and treatment capacity.
