The Supply Analysis
As the technical backbone to Colorado Water Plan efforts, the Statewide Water Supply Initative (SWSI) update is well underway with a scheduled release date of July 2019. Leading up to July, early data insights and tools will be released on this webpage.
This statewide supply study serves two primary purposes:
- Provide a consistent statewide framework for examining future water supply and demand under different scenarios
- Provide tools and data for Basin Roundtables to update their Basin Implementation Plans and develop detailed local solutions to supply and demand gaps.
The study methodologies and technical memorandums were informed by Technical Advisory Group (TAG) participants whom included representatives from each of the roundtables. Check-in for updates and opportunities to learn more about the project as it develops.
POPULATION - Population projections in SWSI are one of the major driver of future water use. The SWSI update utilizes the State Demography Office projections from 2017 (for comparison can be found here). The updated SWSI Technical memorandum including population projection data is linked here and both the methodology fact sheet and insights are also shown.
COSTING - Figuring out exact costs on a water project isn’t always easy to do if the project is conceptual or yet to find full support. However, having some reasonable cost estimate can be helpful to project planning. The Cost Estimating Tool (now in beta form) was developed to help provide a starting point. The Quick Reference Guide and draft Appendix User Guide Manual are resources to guide your use of this new tool. In June 2019, CWCB will host a tech webinar (also listed below) to review the Cost Tool. If you choose to beta test the tool prior to the full release in July, please consider sharing your questions and feedback on this form.
TECHNICAL WEBINARS- Sign-up for one or all of the SWSI Technical Webinars:
- February – SWSI Methodologies Overview and Population Data
- March – Municipal and Industrial Data & Methodologies
- April – Agricultural Data & Methodologies
- May – Environmental Data & Methodologies
- June – SWSI Tools & Next Steps
STATEWIDE BASIN SUMMIT – Join us to discuss SWSI Integration and basin implementation planning. Event is free to CWCB Board, Interbasin Compact Committee, and Roundtable members; $75 registration for others.
IMPLEMENTATION WORKING GROUP – An Implementation Working Group has been developed to help inform some of the expected next steps for integrating SWSI findings and updating the Basin Implementation Plans. The group participants include representatives from each basin and some IBCC members. Group outputs will be updated at this page as they are developed.
