Ludeman Lane Test Well Drilling to Start March

The Regional Groundwater Storage & Recovery Project (GSR) has drilled an additional 13 groundwater wells throughout northern San Mateo County. We at the SFPUC are looking for up to three additional groundwater well station locations to complete the project.  One potential location is on SFPUC-owned property near Ludeman Lane. To assess whether or not this is a viable site for a groundwater production well, we will drill a test well. Work was originally planned to begin in September 2017 but will now begin in March 2018.  We will test the well for two months to determine whether or not the site is viable.

What to Expect


  • A crew of approximately eight people will operate a drill rig to dig an approximately 550 foot well.
  • Expected start of work: Crews will be on-site starting March 12, 2018 and drilling will begin March 19, 2018.
  • Anticipated Drilling Duration: one month.
  • Testing: two months.
  • Construction Work Hours:  Daytime Work: Monday-Friday 7:00 a.m.-7:00 p.m. No weekend or nighttime work is expected at this time.
  • The rig and equipment will stay on site for the duration of the work. The construction area will be fenced off for safety. A security guard will monitor the area after work hours when the contractor is not on-site.
  • The contractors will make efforts to minimize dust and noise in accordance with Millbrae noise ordinances.
  • Green Hills Park users will not be affected during construction.
  • Please avoid the equipment for your safety.

Project Background
Do you have a savings account? We know that having savings is an important part of planning for the future and here at the SFPUC we are looking ahead and saving for our water supply. How does it work? GSR consists of storing water and recovering that water for use during dry-years. This will create a savings account of up to 7.2 gallons of groundwater per day.


The GSR project is designed to help diversify our water supply for drought protection and will ensure we are even more resilient during and after an earthquake or other emergency. Read more: http://sfwater.org/gsr
