Water is rapidly becoming California’s most precious resource and protecting this resource is why California Filtration Specialists, LLC. exists.

California Filtration Specialists was founded by Whitson Contracting & Management, Inc. in 2015, when its staff discovered the need for cost effective, space saving ways to meet the ever-changing requirements in the stormwater industry.  Our products provide solutions to project requirements and design problems related to filtration, infiltration, biofiltration and rain water harvesting.

  • We bring unparalleled expertise in managing stormwater compliance programs on behalf of Legally Responsible Parties (LRPs), Contractors, Industrial property owners, and Commercial Property Owners.
  • We know the permits inside and out, but more importantly, we know how to implement them.
