With declining water sales, water managers have lost over $675 million of revenue in the current drought. The CaDC rate comparison tool provides a quick way to see the implications that a rate shift or a drought surcharge would have on revenue and typical customer bills. The tool quickly illustrates the impact of a shift before a utility hires a rate consultant and goes through a full, labor intensive Prop 218 process.
Future work: This tool currently supports single family residential customers and is being expanded to the entire spectrum of utility customer classes. In addition, future iterations of this tool will support scenario analysis on changes in water sales and ultimately the vision is to incorporate state-of-the-art econometric models estimating the impact of price on water demand from our academic partners. Improving that estimate of the price elasticity of water demand is a key priority of the CaDC research agenda.
Predicting the future
Providing a short term demand forecasting tool to balance peak loads
Faced with a historic drought and future uncertainty, California water managers need all the tools they can get to ensure water reliability. Short term demand forecasting has a long track record of helping manage peak loads in energy, and this new tool created by DataKind brings that approach to help manage recycled water demand peak loads and reduce the need for potable makeup water for irrigation watering. Click the picture below of the dashboard to see the latest version of the tool.
That tackles a key need for Moulton Niguel Water District in South Orange County, which aside from recycled water, is 100% reliant on expensive imported water supplies and serves as a leading example of how improved use of data can ensure water reliability. The graphic below summarizes the value of this approach for Moulton Niguel Water District and the public benefit it provides to California. The underlying code is open source and available here.
