The Water Division provides a high quality and dependable potable water supply to the residents and businesses of Pleasanton.  We strive to maintain a leak-free system that provides continuous service, emergency fire protection and meets the fluctuating demands of the system.  All customer inquiries are responded to as a top priority with skill, respect and efficiency.  The Water Division makes it a high priority to meet all State Health Department standards and to protect Pleasanton’s natural resources and the environment.

Bacteriological and Water Quality Sampling – The City’s Water Quality Control Lab is responsible for ensuring the safety of the drinking water supply.  Routine bacteria sampling is performed to ensure the water is safe to drink.  In addition, many other daily and weekly samples are analyzed to maintain a safe drinking supply, including analysis for chlorine residual, pH, total dissolved solids, ammonia, temperature, conductivity, turbidity, hardness and fluoride concentration.  More information is available in the annual water quality report.

Clean Water Program - By making simple changes and following Best Management Practices (BMPs), people can make a significant positive effect on the water quality of our creeks and the San Francisco Bay.  These BMPs have been developed by many different agencies to give guidance to both business and residents on how to perform routine task in a way that will eliminate or reduce the amount of pollutants conveyed to the storm drain system:


  • New Development and Redevelopment
  • Public Information and Participation
  • Municipal Maintenance
  • Illicit Discharge Control

Computerized Control - Pleasanton's water system is controlled with the use of a sophisticated computerized system called SCADA (Supervisory Control and Data Acquisition) This system connects the pump stations and reservoirs together using a radio telemetry system to communicate to a central control computer at the Water Division.  This system allows us to employ many backup and safety features that would not be possible if it were done manually. In addition we are able to program for more efficient operations and save ratepayers money.


Distribution Stations - The Water Division operates 16 pump stations throughout the City of which three are groundwater well pump stations used to augment the treated water that is distributed. In addition, we operate six treated water stations where the final fluoridation process takes place.


House Service Line - The Water Division is responsible up to the water meter at your home, everything from the meter to your house is the homeowner’s responsibility to maintain and repair.


Storage Facilities - The Water Division operates and maintains 22 storage reservoirs spread strategically throughout the City.  These reservoirs vary in size from 20,000 gallons to over eight million gallons each.  These reservoirs are critical to provide the proper pressure in the system as well as supply during high demands and for emergency firewater protection.


Urban Runoff - Stormwater runoff occurs naturally as part of the hydrologic cycle.  Humans have a large effect on the quality of the water that enters our creeks, streams, and even the San Francisco Bay.  As land use changes from open space to either agricultural or urbanization, the characteristics of the water flow changes.  Urban runoff is the water that flows from these areas after land use has changed.  Urban runoff can be either wet or dry weather flows.
