The City's water quality and supply is maintained by the Water Division, a department within the Sierra Madre Public Works. By providing consistently high quality service to the residents of Sierra Madre we can ensure a safe and reliable method of water delivery for all users. We continue to look for ways we can improve and maintain the City's water infrastructure.

The Water Division has two sources by which they pump, treat, and distribute water. One source of the water supply is derived from four wells drawing from the East Raymond Basin aquifer. The second source is derived from two natural spring tunnels located in our foothills.

Polyphagous Shot Hole Borer (PSHB):The Department of Public Works would like the community to be on alert for the PSHB, which has been found in several areas of the City.  The PSHB is a relatively recent pest that affected a number of public and private trees, mostly in the northern-most areas of town.  The pest is attacking Western Sycamores and Coast Live Oak trees at this time, but has also been found in a few other species. Please click HERE for the most recent information on this pest.
