The Environmental Services Division of Public Works (ESDPW) is comprised of ten Sanitary Sewer Districts. ESDPW has four permitted wastewater discharge points: Main Wastewater Treatment Plant (WWTP), Combined Sewage Treatment Plant (CSTP) 2, CSTP 5, and CSTP 6.
The main plant treats 4 to 5 million gallons per day of wastewater during normal operation. Wastewater originates from homes, industry, and commercial districts. Three districts have combined sanitary and stormwater sewer systems. These are known as Combined Sewer Districts.
Please remember to only flush the 3 P's: pee, poop, and (toilet) paper! If other items such as tissue paper, and feminine hygiene products are flushed, they can clog the sanitary sewer systems and cause backups.
