Stormwater & Vacuum
Hydro Excavation & Utility Daylighting
Klean Lots provides hydrovac excavation across King, Snohomish, Pierce, and Thurston County for utility daylighting, potholing, precise excavation around live infrastructure, and vacuum removal of spoils. Call (253) 410-0159 to schedule a unit.
Hydro excavation exists because mechanical digging near a live utility is a bad bet. Pressurized water breaks up soil and a vacuum removes it, so you expose a gas line, a fiber run, or a water main without touching it.

Hydro Excavation: common questions
What is hydro excavation used for?
Exposing buried utilities safely before you dig — gas, fiber, water, power. Pressurized water loosens the soil and a vacuum removes it, so nothing mechanical contacts the line. It is also used for potholing, trenching in tight areas, and cleaning out structures.
Is hydrovac the same as vacuum excavation?
Hydrovac is a type of vacuum excavation. It uses pressurized water to loosen soil and a vacuum to collect the slurry. The terms hydrovac, hydro excavation, vacuum excavation, potholing, and daylighting are often used for overlapping scopes.
Do you handle disposal of the slurry?
Yes. We haul spoils to approved disposal with our own trucks. Tell us if the material may be contaminated, because that changes where it can go.
Need hydro excavation in the Puget Sound?
Tell us the site and the schedule and we will send a written quote. Monday–Friday, 7:00am–5:00pm, with 24/7 response during snow and ice events.
