Pre-rinse spray nozzle program

Pre-rinse Nozzle

Restaurants, institutions, and commercial facilites in the EBMUD service area are eligible to receive free water-efficient spray nozzles to replace older, inefficient models. EBMUD provides a free on-site water survey in addition to the water-efficient spray nozzle installation. The program can provide significant water, sewer, and energy savings. 

To Participate

  1. You must be an EBMUD customer with a valid business license.
  2. Hoses and conventional spray valve nozzles must already be installed at your facility. 
  3. Call 866-403-2683 or email to schedule an appointment for a Water Conservation Representative to install the water-efficient nozzle(s).

Replacement nozzles will be issued on a first-come, first-served basis until program funds are exhausted or the program terminates, whichever occurs first.
