VIDEO. From the Sewer Authority Mid-Coastside (SAM) meeting on Monday, May 13th, 2024 at 7:00pm, as a hybrid meeting.
SAM’s Lead Operator, Aaron Gilbert, reports back from a recently attended 2024 CWEA (California Water Environment Association) Annual Conference.
NEW TECHNOLOGY: Anaerobic Digestion – World’s Best Digestion
- Bristola cleans digesters while in service
- Best loading rate: SELR (specific energy loading rate)
- Average concentration of Volatile Solids coming into the Digester is about 75% – means that 75% is organic, and the other 25 % is inorganic
- Microbes – Methanogens typical reduction is 50 to 65% VS removal.
- Enhancement of Microbes: C. bescii thrives at 75 c or 165 f
- Digests Cellulose (roughage)
- Process addition created 75 to 80% VS removal
- ➢Thermophilic Anaerobic Digestion
- Sludge de-waters better, but stronger smell
- Advantages: Become Energy Producer, Limit Pollution to Environment, Create Incredible Fertilizer for Crops
- Digests Cellulose (roughage)
Case Study: VCS Denmark
-
-
- Added this extra step of digestion to their solids treatment to supplement their treatment and energy production.
- ➢power positive
- ➢It was an investment into the community and for the environment; however, they were willing to make an effort to help the environment and the community.
- Added this extra step of digestion to their solids treatment to supplement their treatment and energy production.

Summary
-
- We have technology to help improve the process of our digesters. Instead of being an entity that limits pollution into the environment and reduces energy usage, we can become a positive contributor to the environment and help increase our community’s resiliency.
- Become an energy producer
- Create an incredible fertilizer for better crop growth
- Still limit pollution to the environment
- We have technology to help improve the process of our digesters. Instead of being an entity that limits pollution into the environment and reduces energy usage, we can become a positive contributor to the environment and help increase our community’s resiliency.

SAM Directors
SAM is a joint powers authority (JPA) created by its three member agencies: City of Half Moon Bay (City), Granada Community Services District (GCSD), and the Montara Water and Sanitary District (MWSD).
The JPA is a separate, independent, public agency created by the member agencies to perform functions and share powers common to the member agencies. Those powers are outlined in a joint exercise of powers agreement (Agreement). The Agreement creating SAM can be found on the Documents page.
Each Agreement identifies how the independent agency will be governed. In the case of SAM, each member agency appoints two members from its governing board to represent it on the SAM Board of Directors, for a total of six directors.
The Agreement also establishes the weight of each director’s vote. The vote by each representatives from the City is given the weight of two votes. The vote by each representative from GCSD and MWSD is given the weight of one vote. The total number of possible votes is eight. A quorum is a minimum of five votes and resolutions require at least six votes to pass.
