Section 2 Water Demand Moreover, MWDOC, together with its member agencies and the cities of Anaheim, Fullerton, and Santa Ana, has established an Orange County 20x2020 Regional Alliance to assist in reducing the region’s water demand and meet the 20% reduction by 2020. Additionally, Metropolitan has established a goal within its 2010 IRP Update of a 20% reduction in demands in its service area by 2020. This section will identify the key factors affecting water demand, the types of water use within Orange County, and the perspective of expected future water demand for the next 25 years. In addition, this section will describe in detail the formation of the Orange County 20x2020 Regional Alliance, the steps upon how the regional targets for 2015 and 2020 were calculated, and the deduction of recycled water for indirect potable reuse was applied. 2.2. Factors Affecting Demand Water consumption is influenced by many factors, from climate characteristics of a hydrologic region, to demographics, land use characteristics, and economics. The key factors affecting water demand in MWDOC’s service area are discussed below. 2.2.1. Climate Characteristics Orange County has a Mediterranean climate: a semi-arid environment with mild winters, warm summers, and moderate rainfall. The climate is consistent with coastal Southern California. The general region lies in the semi-permanent high-pressure zone of the eastern Pacific. As a result, the climate is mild, tempered by cool sea breezes. The usually mild climatological pattern is interrupted infrequently by periods of extremely hot weather, winter storms, or Santa Ana winds. Orange County’s average daily temperatures range from 58 ˚F in December and January to 74 ˚F in August in a typical year. The average annual precipitation is 14 inches, although the region is subject to significant variations in annual precipitation (Table 2-1). The average evapotranspiration (ETo) is almost 50 inches per year which is four times the annual average rainfall. This translates to a high demand for landscape irrigation for homes, commercial properties, parks, and golf courses. A region with low rainfall like Southern California is also more prone to droughts. Municipal Water District of Orange County 2010 Regional Urban Water Management Plan Final 2-3

In recent years, both regions suffered from multiyear drought conditions and record low rainfalls which directly impact demands and supplies to Southern California. More recently, the dry weather conditions changed drastically in calendar year 2011 to very wet in California and in the Colorado River basin. 2.2.2. Demographics Orange County has a population of more than 3 million people living in a 798-squaremile area. Comprised of 34 cities, from Brea in the north to San Clemente in the south, Orange County is recognized worldwide for its beaches, recreational facilities, and enviable quality of life. According to the Southern California Association of Governments (SCAG) Growth Forecast Report, Orange County is projected to grow by more than 500,000 people by 2030, bringing the total population in Orange County to 3.5 million. Population is a key indicator of regional growth. The population of the MWDOC service area has been calculated by the California State University Fullerton (CSUF) Center for Municipal Water District of Orange County 2010 Regional Urban Water Management Plan Final 2-4
