Project background

Menlo Park Municipal Water (MPMW) provides water to approximately 17,000 residents and businesses within two service areas:  the lower zone located east of El Camino Real and the upper zone located in the Sharon Heights area near Highway 280. MPMW purchases all of its water from the San Francisco Public Utilities Commission's (SFPUC) Hetch Hetchy system. There are no storage facilities or secondary water supplies for the lower zone, and as a result, nearly 3,000 residents and businesses could be without water immediately for an undetermined period if earthquake damage or other emergency interrupts the availability of the SFPUC supply. Studies indicate that MPMW could be without water for as long as 20-30 days while SFPUC repairs the damage.
 

Project goal


The goal is to provide 3,000 gallons per minute for the lower zone, which can be met by constructing 2 to 3 backup wells.

Design and construction of a backup well consists of three steps:
  1. Environmental review
  2. Well drilling
  3. Construction of the well facility

City staff are in the process of reviewing existing data and further analyzing the preliminary well site ranking that was last established in 2013 as shown below.

Well site ranking by tiers (January 2013)


Tier 1 - Most desirable
  • City Corporation Yard
Tier 2 - Desirable
  • Menlo Park Fire Protection District Station No. 1
Tier 3 - Potentially feasible
  • Willow Oaks Park - 1 site
  • Burgess Park (Burgess/Alma)
  • Burgess Park (Ravenswood)
  • Alma site
Tier 4 - Less feasible
  • Willow Oaks Park - 2 sites
  • Seminary Oaks Park - 2 sites
  • Pope/Laurel site
