Wastewater treatment plants range from small privately-owned facilities treating sanitary wastewater from a housing development to large regional facilities treating millions of gallons a day of sanitary and industrial wastewater. Plants owned by municipalities are commonly called Publicly-Owned Treatment Plants, or POTWs. In cooperation with local and federal authorities, MassDEP regulates many types of wastewater treatment plants.

The new Technical Report #16 (TR-16) covers in detail the important elements of wastewater treatment that must be considered in the design of wastewater treatment works. The content, however, has been completely updated to reflect current practices and to include advances in technology, nutrient removal, energy efficiency, and instrumentation. The intended audience includes engineers who design wastewater treatment plants, state regulators who review and approve designs, and municipalities that are soliciting professional design services for wastewater treatment facilities.
