VIDEO. When the Portola Pump is shut down for maintenance, sewage is stored in the inter-tie pipe running from Half Moon Bay to Montara. When a storm hits, storms water run off enters the system and adds to the effluent which make a normal backup, more critical. A few years ago 200,000 gallons wet weat
Approved an additional wet weather storage of 200,000 gallons bringing the total wet weather storage at Portola to 400,000 gallons. 200,000 gallons of storage is already placed at Burnham Strip in El Granada. Another 200,000 has been approved.
In future, consider increasing the capacity to a total of 600,000 gallons.
Approximate cost of 2019 is $ 1,466,000.
Pumps are expensive and require constant maintenance. Storage is passive, with little maintenance.
Expenditures for either project are similar.
The regional water board must approve the project, too.

From Sewer Authority Mid-Coastside (SAM) 3/9/2020 Board Meeting
The purpose of this report is to discuss the updated costs of construction of the Wet Weather Storage Expansion Project and authorize the award of a contract to complete the work.
The total fiscal impact of awarding the construction contract to the apparent low bidder is $1,298,600. Of this total, $700,000 was included in the FY 2018-19 budget, along with an additional $300,000, one-half of the negotiated administrative civil liability that was suspended by the San Francisco Regional Water Quality Control Board (RWQCB) on the condition that SAM proceed with the Wet Weather Storage Expansion Project as an Enhanced Compliance Action; the balance of $298,600 in additional construction costs will need to be provided by the Member Agencies and affirmed by a mid-year budget adjustment.
