Certified Trash Full Capture Systems Available to the Public

The information provided on this page has been developed by the State Water Resources Control Board. To facilitate access, CASQA is hosting this information on our website. The certification of all systems is determined solely by the State Water Board.

Please direct all questions to Leo Cosentini by email at Leo.Cosentini@waterboards.ca.gov or by phone at (916) 341-5524.

Note: This page is for information about Certified Trash Full Capture Systems Available to the Public. You can view information about Certified Multi-Benefit Trash Treatment Systems here.

Trash Provisions

To qualify as a trash full capture system (System) as described below and satisfy the requirements of the Trash Provisions, a System installed after December 2, 2015 must be certified, prior to installation, by the State Water Resources Control Board (State Water Board) Executive Director, or designee, that meets the full capture system definition. The Trash Provisions define a full capture system as a treatment control, or series of treatment controls, including but not limited to, a multi-benefit project or a low impact development control that traps all particles that are 5-millimeter or greater, and has a design treatment capacity that is either:

1. Of not less than the peak flow rate resulting from a one-year, one-hour storm event (design storm) in the subdrainage area, or
2. Appropriately sized and designed to carry at least the same flows as the corresponding storm drain.

Consistent with these requirements, the Systems shall not bypass trash below the design storm under maximum operational loading conditions and shall not have a diversion structure present upstream such that a portion of the peak flow is not treated to trap all particles 5-millimeter or greater. 

¹ Amendment to the Water Quality Control Plan for Ocean Waters of California to Control Trash and Part 1 Trash Provisions of the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, And Estuaries of California adopted by the State Water Board.

Vector Control Accessibility

According to the California Health and Safety Code, California landowners are legally responsible to abate (eliminate the source of) a public nuisance arising from their property, including mosquitoes. Mosquito vector control districts have substantial authority to access public and private property, inspect known or suspected sources of mosquitoes, abate mosquito sources, and charge the landowner for work performed and/or charge fees if a landowner is unwilling or unable to address a mosquito source arising from their property. 

If not designed properly, a System may impede the mosquito vector control district’s ability to (1) visually inspect the System and/or storm vault for mosquito breeding, and (2) apply the appropriate chemical treatment. Moreover, some Systems may create a habitat for mosquitoes.

All the Systems in the tables below have been reviewed and approved by the Mosquito Vector Control Association of California for vector control accessibility. However, prior to installation of any Systems, the local mosquito vector control district should be contacted to ensure the installation conforms to the local district’s visual inspection, treatment, and vector breeding minimizing guidelines. The Mosquito Vector Control Association of California may also be contacted via email at: Trashtreatment@mvcac.org.

Certified Trash Full Capture Systems Tables

The Systems included in the tables below are: 1) new Systems certified by the State Water Board Executive Director, or designee, after adoption of the Trash Provisions, and 2) legacy Systems that were certified pursuant to the Trash Provisions that include those full capture systems that were listed in Appendix I of the Bay Area-wide Trash Capture Demonstration Project, Final Project Report (May 8, 2014). All Systems remain certified unless and until they are decertified by the State Water Board’s Executive Director or designee. Legacy Systems’ descriptions are included in “fact sheets” that have been updated to address the application requirements for new Systems. The tables below include the names of the applicants or owners of the certified Systems. The tables also include the dates of certification and, if applicable, the date of any update or decertification.

² Health & Safety Code sections 2001-2002, 2060-2067, 100170, and 131075.

The tables do not include the Department of Transportation’s Systems as its Systems are not available to the public. To obtain the Department of Transportation’s certified Systems applications, or have any questions concerning the Trash Provisions or tables below, please contact Leo Cosentini by email at Leo.Cosentini@waterboards.ca.gov or by phone at (916) 341-5524.

Systems are either identified by their application number or, for legacy Systems, by a fact sheet alpha numeric designation. 

Please note: Only Systems originally manufactured and distributed by the listed applicants are certified full capture systems.

The alphabetical tables of Systems are divided into two categories:

• Catch Basin Inserts and Other Insert Systems. These Systems typically are inserted into existing stormwater infrastructure; and
• High Flow Capacity Trash Full Capture Systems. These Systems are generally self-contained units that typically are not inserted into existing stormwater infrastructure and that are designed to treat trash from large drainage areas.
