Why stormwater matters

Washington compliance

Washington's stormwater rules make catch basin cleaning a documented, inspectable legal obligation for commercial property owners — not optional upkeep.

The ROI math

Routine service keeps a property's entire drainage system draining as designed, preventing the standing water that accelerates pavement failure and the emergency flood repairs (often $25,000–$50,000 per incident) that hit when neglected systems inevitably back up

Repairs & replacements

Because the same crew that cleans a basin is the crew positioned to spot a cracked frame or failing line early, routine vactor service doubles as an inspection program that turns costly emergency excavations into scheduled, low cost repairs handled by one vendor.

Hydro excavation

Hydro excavation exposes buried utilities with pressurized water instead of mechanical force, making it the safest way to dig near live lines when utility strikes cost the U.S. economy tens of billions of dollars a year and can run from thousands to over a million dollars per incident.

Connected by design

Stormwater compliance depends on every service on the property doing its part. Sweeping keeps sediment from reaching the basins; catch basin cleaning and inspections catch what gets in anyway; landscaping protects drainage paths from erosion; and porters flag hazards the moment they spot them. Running the full program under one vendor means nothing falls between service lines.

Sweeping

Keeps debris moving away from drains and helps protect the systems below.

Landscaping

Supports water flow, healthy plantings, and well-maintained edges across the site.

Repairs

Addresses surface and infrastructure issues before they create broader property problems.
