How the individual functions of each Division of Water Quality program apply to regulating and funding a wastewater treatment system discharging into a surface waterbody

NJPDES Program

The NJPDES Program protects New Jersey's ground and surface water quality by assuring the proper treatment and discharge of wastewater (and its residuals) and stormwater from various types of facilities and activities. To accomplish this, permits are issued limiting the mass and/or concentration of pollutants which may be discharged into ground water, streams, rivers, and the ocean. The types of regulated facilities can range from very small users such as campgrounds, schools, and shopping centers to larger industrial and municipal wastewater dischargers. Before a new wastewater treatment plant can be constructed, its proposed discharge must be authorized under a NJPDES permit. The permit will contain discharge pollutant limits sufficient to safeguard the integrity of the receiving waterbody. The limits also provide an engineer with the information needed to determine how to design a new treatment plant, or upgrade an existing one.

Treatment Works Approvals

After a discharger has obtained a NJPDES permit, it is necessary to obtain a Treatment Works Approval for a new treatment plant (it is sometimes necessary to obtain a Treatment Works Approval to upgrade an existing treatment plant if additional treatment facilities must be constructed to meet new permit conditions). 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. Treatment Works Approvals also include 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.

Wastewater Financing Programs

All of these programs have a role in protecting and improving New Jersey's water. But the overall picture would not be complete without the regulated community and interested environmental groups, who, by working with the division, make an enormouse contribution by helping to develop and implement water quality initiatives.
