Timelines and Key Information

NEW—SSMP Resource Database

As part of the Waste Discharge Requirements, every collection system all publicly owned sanitary sewer collection systems in California with more than one mile of sewer pipe must develop a Sewer System Management Plan (SSMP). The plan must include at least the eleven mandatory elements, and be approved by the collection system's governing body. The SSMP will be comprehensive, and so the WDR (plus a 6-month extension occasioned by the memorandum of agreement  between CWEA and the SWRCB) has  included a roll-out schedule for compliance based on population served.

Training and Plan Development Tools

Training on the SSMP

The California Water Environment Association (CWEA) and its Summit Partners (CASA, BACWA, SCAP, CVCWA) announce the second of the SSO-WDR Compliance Workshops: “SSMP Requirement 1: Developing Your Plan”  With the new GWDR in full effect and electronic reporting live, come and learn about the other critical requirement in the GWDR — Sewer System Management Plans.  In this full –day workshop you’ll learn what is required and when by reviewing 12 components of the SSMP requirement with a team of other industry staff. 


You’ll receive a reference manual written by a team of industry subject matter experts and reviewed and approved by the State Water Board staff.  The manual contains descriptions, resources, and information for each of the 12 SSMP components to help you know how and when to comply.  A gap analysis tool is included to help you assess the readiness of your agency to develop your SSMP.   Take the reference manual back to your agency to use when you actually create you Sewer System Management Plan.  Keep the manual up to date with your agency’s progress


You’ll leave this workshop with an understanding of what you need to develop an SSMP and when. You will not be creating an actual SSMP during the workshop.  You will receive access to samples that we’ll collect as they become available.


 The workshop is specifically designed for those who are or will be developing Sewer System Management Plans in California’s collection systems.  Come prepared to benefit from a workshop that uses the latest techniques in adult learning, including team exercises with your colleagues. 


4.3 million reasons why you should attend this workshop

The City of Modesto recently conducted a gap analysis and realized the price tag to fully implement their SSMP could cost as much as $4.3 million.  And, it will take Modesto 30 months to meet the requirements.  At this workshop you’ll get a good sense of the time it will take for your agency to put all the pieces in place for your SSMP.
