What is the CaDC?

The California Data Collaborative or “CaDC” is a collaborative project where local cities, water retailers, and land planning agencies have come together to build new data infrastructure to ensure California has reliable water today and into the future. In strict accordance with our in-depth policy principles, the CaDC automates collecting, cleaning, and securely storing metered water use data from participating agencies. These data encode the story of how much water was used, when it was used, and where the water was applied. On top of this data platform, we develop tools and research with freely available open-source technology and globally respected research institutions including Stanford, UCLA, USC, UC Riverside, and UC Davis.

This integrated platform approach creates value in several ways:

  • Network of Talent -- A key benefit of the CaDC is the time, effort, and institutional knowledge of the utility staff that participate in the regular Data Action Team meetings (see below) to drive the development of CaDC analytics.

  • Ongoing analytics -- Up to date water data powers interactive analytics. The underlying data is not shared though the code powering those tools is made open-source where possible on the CaDC Github.

  • Novel research -- The investment in cleaned data can be leveraged by sharing the data with utility approved academic partners according to the CaDC data sharing protocols included the metadata documentation.

Our goal is to create meaning out of customer data in a way that will inform objective policy analysis and support water managers in measuring program effectiveness, targeting water efficiency actions and ensuring revenue reliability in times of changing water sales.

Governance and Participants

Two months after launching in January 2016, the CaDC was honored by the White House for the founding water managers’ visionary investment in this concept. This coalition has grown to include world leading academic, tech companies and nongovernmental organizations to increase the value of this investment on behalf of the people of California. The CaDC operates as a 501(c)3 nonprofit to ensure alignment with the goals of our water management partners and is governed by a steering committee composed of subscribed participating agencies. See our governance page for more details and meet our participants below.
