Power plants, mine sites and other large facilities or operations must often treat the stormwater created on their facility grounds. Industrial sites can generate runoff containing different types of contaminants including arsenic from coal pile runoff to mercury, selenium, metals and other pollutants from a variety of processes, which must be treated to compliance prior to discharge.
Xylem has decades of experience with water and wastewater treatment, including stormwater. The chemistry of the water will determine the type of treatment used, however our solutions can include media such as clarification, granular activated carbon (GAC), resin, membrane solutions, biological treatment, and other solutions that will meet the treatment goals.
Xylem also provides emergency and mobile solutions when water treatment is an immediate need. We can provide the appropriate pumping and water transport solutions to direct water from personnel or areas where safety may be a concern.
These temporary systems can also be moved into place proactively prior to seasonal weather fluctuations to maintain effluent compliance and general uptime. Our water treatment services can also be combined with pipeline maintenance, maintenance contracts and other scheduled services.
Xylem provides tailored options backed by an extensive service network. Real-time data, monitoring, and forecasting capabilities further enhance performance by supporting more proactive operational decision-making as weather and flow conditions change. The result is improved system visibility, more efficient use of infrastructure, and greater readiness for both routine operations and storm events.

Frequently asked questions
Stormwater treatment solutions remove pollutants such as sediment, oils, heavy metals, nutrients, and other contaminants before runoff is discharged into natural waterways. This helps protect aquatic ecosystems and supports environmental compliance.
Treatment requirements depend on the contaminant profile of the stormwater being discharged. Common treatment approaches include UV disinfection to inactivate pathogens in combined sewer overflow events, specialty adsorptive media — including organoclay and activated carbon — to remove hydrocarbons and heavy metals from industrial stormwater, and physical filtration to reduce suspended solids and turbidity. Modular and vessel-based treatment configurations provide flexible deployment options that can be rapidly mobilized, as demonstrated by a Southern California refinery that resolved NPDES stormwater discharge permit violations within five days using a Xylem vessel-based treatment system.
