CCWD: 80 Years of Growth & Service

80 Year Logo copy

Providing Essential Services
for Eight Decades

The quest for reliable, high-quality water is the reason the Contra Costa Water District was formed 80 years ago in 1936.

That drive shapes nearly every aspect of the District's remarkable history.

Though the District was first organized in 1936, it wasn't until 1940 that CCWD delivered its first water to the city of Pittsburg, and 1961 when it delivered drinking water. 

Today, CCWD serves 500,000 people within an area that stretches from Martinez to Antioch.  The District has four pumping plants (all with screens that protect fish in the Delta), owns and operates the largest reservoir in the Bay Area, serves treated and untreated water, and employs 290 people. It's the only water district that depends solely on the Delta for its water supply. 

Here are some numbers about the Water District and its history.


Megawatt, the amount of power the small hydroelectric plant at the Antioch Service Center produce.  


  The number of  General Managers that have served through the 80 years.
10   The number of Board Presidents.


  The number of treated water storage reservoirs in the District.


The length in miles of the Contra Costa Canal.


 Million gallons of water per day produced by the Bollman Water Treatment Plant at its peak capacity.


 The number of connections the District had in 2014.  


 The number of acre-feet of untreated water the District can store in its four untreated water reservoirs (Martinez, Contra Loma, Mallard and Los Vaqueros) combined. 

Size of the District's Service Area -- in acres -- through the years:

1941 -  47,645
1952 -  86,000
1960 - 108,000 
1966 - 109,000
1997 - 132,022 
2014 - 137,127
