Stormwater Solutions for Civil Infrastructure

Keep your highway, bridge, dam, utility, or water facility project compliant and on schedule. We treat the dirty water your site produces and prove it meets EPA and WSDOE limits before it leaves the property.

Your Project Can't Afford a Stormwater Violation

Civil infrastructure jobs run long, disturb huge footprints, and generate water that's harder to treat than anything on a standard build. High pH off fresh concrete. Sediment-loaded runoff. Drill water with nowhere clean to go.

One failed turbidity reading or a regulator showing up to discharge you don't have under control, and you're looking at stop-work orders, fines, and a schedule that slips while everyone waits on you.

You need a partner who treats this water to compliance and can prove it, without becoming the reason your project falls behind.

Stormwater That Passes on the Toughest Civil Sites

We've spent 20+ years treating stormwater on civil construction sites across Washington. We've handled drill water on major state highway deck construction and run treatment at active rock quarries and pit operations.

We routinely knock down stormwater with a pH above 12 during vault and wall pours. That's the kind of water that fails on most sites and stalls the job, and it's routine for us.

Our core system is chitosan-enhanced sand filtration (CESF). It captures the fine sediment and contaminants that slip past ordinary filters, so the water leaving your site clears turbidity and compliance limits every time.

Stormwater Management Built for Long Civil Timelines

Civil infrastructure projects produce higher contaminant loads than standard builds, and they run for months or years rather than weeks. That combination is exactly where stormwater programs tend to break down. Discharge points that worked in phase one get buried under phase three. Treatment that handled early sediment can't keep up once concrete work starts throwing pH.

We design for the whole timeline, not just the kickoff. As your site changes, our systems move and scale with it, so you keep water off impervious surfaces, out of the storm drains, and inside compliance from mobilization through closeout.

Why Civil Infrastructure Teams Call Us

Fast 36-Hour Mobilization

Need treatment on a new site fast? We mobilize and have you discharging clean water within 36 hours, often sooner, so your schedule never waits weeks on us.

Systems That Scale to Any Site

From a 50-75 GPM trailer unit to a 150 GPM gooseneck rig, down to a toolbox enclosure for pH only. Self-contained and built to follow your work.

Compliance You Can Document

Technology-driven monitoring and predictive analytics document that your discharge meets EPA and WSDOE limits. When an inspector shows up, you already have the full paper trail ready.

Two Decades on Civil Sites

Hands-on presence from a team that has run this water on real civil jobs for twenty years. We handle the high-pH water that stalls other crews.
