Longview's Sewer Division maintains and operates the sewer collection system, repairs broken sewer lines and operates pump stations.
Like most municipal wastewater service providers, our wastewater treatment facilities and systems are designed and operated for urban, domestic wastewater, industrial and commercial wastewater, however, they may contain concentrations of metals, organics, fats oils and greases which can be far above normal domestic wastewater. Even our advanced treatment systems are not designed to remove these contaminants. The City of Longview’s Pretreatment Program protects our wastewater collection system, treatment facilities and environment from uncontrolled toxic pollutants. Any facility that discharges non-domestic wastewater to our sanitary sewers must meet Clean Water requirements. This includes commercial establishments, such as restaurants, as well as manufacturers, fabricators, blenders and others.
The best place to prevent pollution is at the source. Prevention practices keep pollutants out of wastewater and reduce treatment costs and collection system pipeline failures. Pretreatment can make wastewater safe to discharge to sanitary sewers. Find out how you can take the right steps for your business to ensure your discharge is safe.
