California Water Rate Survey Results 2017 |
|
The California Data Collaborative ("CaDC") is a coalition of water utilities that have pioneered a new data infrastructure non-profit 501 (c) (3) to support water managers in meeting their reliability objectives and serve the public good.
One important contribution of the CaDC was to establish a standard format and to provide the infrastructure for storage and maintainance of an open database for water rates, facilitating the work of analysts, economists and software developers interested in analyzing and understanding the differences in water rate structures and prices across many different agencies and locations. The water rate structures were organized in Open-Water-Rate-Specification (OWRS) files, a format based on YAML, which is designed to be easy to store, transmit, and parse in any programming language while also being easy for humans to read.
This report presents a summary of the types of analyses and insights that can be obtained from analyzing the OWRS, especially when this information is combined with the water consumption data from water agencies and Census Data.
This report provides the combined analysis of data from 4 different sources:
- Water Rates from the Open-Water-Rates-Specification.
- Water Consumption data reported by the water agencies [ADD MORE DETAIL]
- Demographic Data from the American Community Survey [??]
- Qualitative Data from a Survey realized by the California Data Collaborative with water agencies in 2017.
