Construction Water Treatment

Starting a new construction project involves numerous tasks: creating blueprints, obtaining building permits, conducting pre-construction inspections, breaking ground, etc. However, if you’re a construction manager, you’ll also need to consider stormwater treatment and construction dewatering throughout your building process.

At Washington Stormwater, we have extensive experience servicing construction clients throughout Whatcom, Snohomish, King, Pierce, and Thurston counties. As a result, we know the best technologies, tools, and processes to filter your construction stormwater and ensure your compliance with environmental regulations.


Why Is Dewatering Important In Construction?

Most construction projects take place outside or in areas not covered by an overhang or ceiling. Additionally, the nature of construction work requires contractors to use a range of hazardous materials that could contaminate water sources.

When rain falls on outdoor construction projects, the water that touches the construction site picks up contaminants and pollutants from the soil, metal, and other surfaces, becoming turbid. Without proper water treatment processes in place, that water can then drain to ponds and lakes, disrupting the ecology and becoming unsafe to drink.

Construction dewatering is the process of removing surface or groundwater from your construction site and filtering out contaminants before the water pools within the construction site or naturally flows into rivers. This process can vary significantly depending on your project’s specific water treatment needs.

Dewatering is crucial in Washington, as the state experiences a severe rainy season from October through March. Additionally, most soil in Washington has high silt content, which holds a negative charge and cannot settle in ponds or lakes. Chemically enhanced filtration is necessary to remove these particles from construction tanks.

Potential Construction Water Contaminants

Construction sites can contaminate rainwater with a range of pollutants. A few of the most common contaminants we filter through our systems include:

  • Oils
  • Heavy metals
  • Grease
  • VOCs
  • Paints
  • Diesel
  • Sediment
  • Glues
  • Cement
  • Other toxic chemicals

Our team uses reliable filtration and dewatering processes to remove contaminants from construction stormwater and restore the water to safe and compliant pollutant levels.
