Montara Sewer Engineers Identify Water Hammer as the Cause for the Force Main Damage in Montara Due to HMB Closing Off IPS to Save SAM Plant

Getting your Trinity Audio player ready...

VIDEO. From the Midcoast Community Council (MCC) meeting on Wednesday, February 22nd, 2023 at 7:00pm by Zoom.

 


MCC Chair, Gregg Dieguez, gives, Montara Water and Sanitary District’s Kathryn Slater-Carter and opportunity to speak:

“In 2017, the El Granda Force Main cost $250/linear foot to replace. In 2023, the cost to replace the same type of pipe for the Force Main in Montara is $500/linear foot, and construction index and CPI keep going up.

The Water Hammer Effect that caused the SAM Force Main in Montara to break in 2023 was reported in the 2009 Infraturcture Report. We have known for 14 years that there was the potential for water hammer.”

 

“Water hammer is a phenomenon that can occur in any piping system where valves are used to control the flow of liquids or steam. Water hammer is the result of a pressure surge, or high-pressure shockwave that propagates through a piping system when a fluid in motion is forced to change direction or stop abruptly.  It is also known as a hydrolic shock.” ~ Wikipedia

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.
