The primary purpose of the IRWM Plan is to encourage integrated planning among the agencies in the IRWM Region. In particular, the need to improve water supply reliability by implementing local supply projects is recognized as a priority given that imported water is increasingly viewed as a less reliable supply, and considering that the water purveyors within the Region rely on imported water to meet between 13% and 16% of their demands. As the IRWM Region continues to implement the strategies in the IRWM Plan, it will be better positioned during drought periods.
