This guidebook is designed to help water suppliers comply with the “Making Conservation as a California Way of Life” framework (WUE Regulation), focusing specifically on the classification of Commercial, Industrial, and Institutional (CII) water users in accordance with Section 972. The guide provides a standardized approach for classifying CII accounts, offering methodologies to enhance water use benchmarking across sectors, and reduce subjectivity between suppliers. Following this guide will help water suppliers meet regulations, find high water users, and create better water-saving strategies.
Goals and Objectives:
1. Help water suppliers meet Section 972 requirements mandating annual classification of CII water users.
2. Provide clear instructions for classifying CII water accounts using ENERGY STAR categories, along with additional classifications for laundries, irrigation meters, water recreation, and car washes.
3. Support accurate benchmarking to identify high water users and opportunities for targeted water conservation measures.
4. Establish a clear timeline and methodology for suppliers to achieve and maintain at least a 95 percent classification rate of all CII water users.
