Water Shortage Levels of Action
The MPWD's WSCP contains six standard water shortage levels of up to 10-, 20-, 30-, 40-, 50-, and greater than 50-percent shortages. A systematic approach and framework were developed for the MPWD’s 2020 WSCP, which included the necessary flexibility for MPWD and practical, initial voluntary conservation levels, followed by mandatory water rationing in response to increasingly severe water shortages. MPWD’s shortage levels align with its response actions that will be implemented to meet the severity of future shortages.
