California State Water Resources Control Board, Full Capture Approval of the Deflective Screening Device
California State Water Resources Control Board
Approves the Deflective Screening Device (DSD) Stormwater Separator
The Deflective Screening Device (DSD) is a low-cost, yet proven stormwater system now with approval by California for Full Capture treatment – capturing 100% of trash and debris (equal to or greater than 5mm in diameter). The DSD utilizes a unique and effective non-clogging design that ensures high treatment flow rates are controlled, but is also one of the easiest separators to maintain given the easy-access sump chamber.

What it Means
According to the Water Boards website criteria, Full Capture Certification for Trash Total Maximum Daily Loads (TMDLs) requires a system “to trap all particles retained by a 5 mm mesh screen and has a design treatment capacity of not less than the peak flow rate Q resulting from a one-year, one-hour, storm in the sub-drainage area.” Q=CIA
The Deflective Screening Device (DSD) has achieved this, and is still one of the easiest separators to clean with a typical vac truck:
- Meets California Full Capture Requirements
- In-line design allows for internal high flow bypass
- Low cost alternative to more expensive deflective shield separators
- Non-clogging screening technology
- 100% Noncorrosive internal components
- Easiest separator to maintain with easy access to sump using standard vac hose
