The Regional Water Reliability Plan (RWRP) and Regional Drought Contingency Plan (RDCP) are concurrent, closely related planning efforts to evaluate the vulnerabilities of the water resources of the region and to identify the most promising opportunities to improve long-term water supply reliability at the agency, sub-regional, and regional levels.
The RDCP is partially funded through a Drought Contingency Planning Grant awarded through the United States Bureau of Reclamation. The RDCP focuses on mitigation actions and near-term responses specifically related to drought conditions. The RWRP goes beyond the scope of the RDCP by evaluating a broader set of vulnerabilities and mitigation actions. For example, the recent adoption of a California water quality standard for hexavalent chromium has impacted a number of water suppliers that use groundwater as a primary supply source; mitigation actions for addressing this will be different than those for addressing dry conditions.
