The City of Port Arthur maintains 57 sewer lift stations throughout the wastewater collection system and nearly 400 miles of sewer mains and transmission lines throughout the City.
Water mains are flushed on a monthly basis. This maintenance activity uses a high velocity flow of water in the opposite direction of natural flow to keep the water mains clean and fresh. During flushing, any sediment that may be in the main is released out of the hydrants. Customers may notice short periods of water discoloration; however, this program is essential to maintain water quality and public health. If customers experience any change in water quality following maintenance activities or have security concerns regarding Port Arthur Water District employees, please call Wastewater Treatment.
The Wastewater Treatment Plant (WWTP) department operates and maintains the City's three activated sludge treatment plants, measured in Gallons per Day (GPD). The WWTPs remove an average of 99.5% of contaminants from wastewater.
