Jamison Way Water Main Extension Project

Project details

Beginning January 14, 2019, EBMUD crews will install a new water pipeline to improve water service in your neighborhood. We will be working at 3544 Jamison Way, Castro Valley. We expect to complete pipeline installation by February 2019, with final paving to follow.


Work hours are 7 a.m. to 4:30 p.m., Monday through Friday. We will provide traffic control. Residents may experience delays of up to 10 minutes when entering and leaving the work area. If you have special needs, please call us and we will make every effort to accommodate.


What to expect 

  • Equipment and materials will be temporarily located in your neighborhood during construction.
  • After the new water pipeline is installed, crews will transfer water services, install fire hydrants and make final connections.
  • Once construction is completed, material and equipment will be removed within 1 to 2 weeks. 

Water service interruption 

Crews will notify you, in person or with a door hanger, regarding planned water service interruption to your property. After a service interruption, there may be air in the pipes that may loosen particles in your home plumbing. Close your toilet water supply valves, and then run water from your front hose bib, bathtub and/or cold water faucets for 1-3 minutes. This will dispel any air or loosened particles from your household pipes. If any water quality issues remain after flushing, please call us.


The asphalt paving applied daily is temporary and is designed to provide a safe road surface during construction. Final paving occurs after pipeline work is completed. It may take up to 30 days or longer before final paving is completed.
