SECTIONTHREE Establishing Base - Year Conditions Fixture models are used for two purposes: • To model the base-year water use, accounting for and reconciling the fixture data to what the current level of efficiency is in the homes and businesses, and • To forecast the impact of replacing the current inefficient fixtures with more efficient models over time in existing base-year accounts and in new accounts. These replacements result in water savings that are incorporated into the demand projections and are discussed in Section 4 of this report. For this study, a typical model has up to 8 fixture models. The number of fixture models applied is related to the number of applicable customer-billing categories for each wholesale customer.
