Design-Build
Stormwater Treatment Systems

Whitson CM’s extensive experience, in conjunction with California Filtration Specialist’s design resume , make for the perfect combination to provide affordable and effective stormwater treatment systems.

Whitson CM provides design-build services for stormwater treatment systems in partnership with California Filtration Specialists (CFS). In 2016, Whitson CM founded CFS to provide innovative stormwater treatment systems that will dramatically reduce costs and improve discharges from properties. As members of a partner firm, Whitson CM employees have the knowledge and expertise to develop, design, budget, permit, and construct any CFS stormwater treatment system. Our team utilizes our expansive knowledge of construction management and stormwater compliance (CGP, IGP, MS4) to bring expertise to every step of the process, from design, to install, and finally to post construction maintenance.

Whitson CM and CFS are proud to introduce the next generation of post-construction BMPs, featuring infiltration, biofiltration, rainwater harvesting, permeable surfacing, and pre-treatment and filtration products. CFS has partnered with Convergent Water Technologies, Fabco Industries, Inc., PURUS NA Ecoraster Inc., Parjana, Pacific Stormwater Systems, and PaveDrain to offer state-of-the-art stormwater solutions, exclusively in the Western United States. All of our products are guaranteed to reduce both the footprint and costs required to achieve any project’s water quality objectives.

Permeable Surfacing

Infiltration is the process by which stormwater and groundwater permeates into the soil. Using infiltration to capture or prevent stormwater runoff is the primary approach to complying with today’s stringent post-construction standards.

Storage & Infiltration Systems

Storage and infiltration systems allow landowners and businesses to capture and store stormwater for infiltration into the soil to recharge groundwater, detention to manage the volume and flow of runoff, and/or rainwater harvesting. Water use, especially for lawns and landscaping, is being severely restricted due to the ongoing drought. Rainwater harvesting is a technique used for collecting, storing, and using rainwater for landscape irrigation and other uses.

High-Flow Biofiltration Systems

Many developers turn to biofiltration to treat their stormwater runoff, but they must surrender massive land areas to accomplish modest goals. Biofiltration is a pollution control technique that uses living material to capture and biologically degrade pollutants found in stormwater runoff. Whitson CM and CFS offer high-flow biofiltration systems with scalable footprints which can treat large volumes of stormwater, handle fast flow rates, and maintain high pollutant removal.

Filtration Solutions

With today’s post-construction BMP manuals and the requirements of the Industrial General Permit, stormwater filtration is now a required practice. Trash reduction BMPs are also required by many municipalities and are an easy and cost-effective way to maintain compliance with stormwater quality standards and regulations. Whitson CM and CFS offer many pretreatment and mechanical filtration BMP products which can be adapted for various new and existing stormwater drainage systems.
