Stormwater Treatment

Modular wetland systems, bio-retention and underground treatment that clean runoff before it leaves the site.

Request a Bid

Almost every new project in Southern California has to treat its runoff before it leaves the site. Slater installs the systems that do it: modular wetland systems, bio-retention, hydrodynamic separators and underground detention, tied into the storm drain we build.

What we build

  • Modular wetland systems
  • Bio-retention basins and planters
  • Hydrodynamic separators and pretreatment structures
  • Underground detention and infiltration chambers
  • Catch basin filter inserts and connections to the storm drain

Who hires us

National homebuilders and developers hire us to install the treatment systems required by their water quality plans. General contractors bring us in on commercial and public projects. Public agencies use us for treatment retrofits on existing storm drain.

How we run the work

We install to the manufacturer’s details and the approved water quality plan, coordinate delivery and setting with the manufacturer’s rep, and build the concrete, piping and connections ourselves. The same crew that builds the storm drain sets the treatment unit on it.

FAQ

Questions we get about stormwater treatment

Which treatment systems do you install?

Modular wetland systems, bio-retention basins, hydrodynamic separators, filter inserts and underground detention. We install to the manufacturer's details and the approved WQMP.

Do you coordinate with the system manufacturer?

Yes. We schedule delivery and setting with the manufacturer's rep and have them on site for startup and sign-off when the spec requires it.
