A i i- R i v I I i I <br />RIVERSIDE PUBLIC UTILITIES <br />Board Memorandum <br />PUBLIC UTILITIES <br />BOARD OF PUBLIC UTILITIES <br />DATE: SEPTEMBER 10, 2018 <br />GENERAL MANAGER'S REPORT <br />ITEM NO: <br />Summary of Riverside Public Utilities <br />Urban Water Production and Conservation Efforts / Groundwater Level <br />Update As of July 2018 <br />Conservation Efforts <br />RPU's urban water production in July 2018 was 7,469 AF. This is an increase from last July by <br />267 AF or a drop in conservation of 3.6%. Weather conditions showed similar patterns for rainfall <br />with respect to July 2017. July of 2018 was warmer by about 1.7 degrees compared to last year. <br />RPU is still within the historical production range from 2013 to 2017 as shown in Figure 1. Figure <br />1 also shows that RPU's projected annual urban water production in 2018 is 65,400 AF which is <br />below the compliance target specified in SB X7-7 (i.e. 20% reduction by 2020). The projections <br />for the 2018 urban water production is based on current trends of increased consumption and can <br />be affected by the permanent water prohibitions implemented by the State and/or the return of <br />drought conditions. The projected annual urban water production is also below RPU's current <br />potable rights, which potentially can maximize RPU's passive assets by 6,700 AF through <br />wholesale to Western Municipal Water District. <br />Basin Groundwater Levels <br />Groundwater levels in the Bunker Hill, Rialto -Colton, and Riverside North basins are continuing <br />to show a long-term declining trend, while groundwater levels in the Riverside South Basin <br />remain relatively stable as shown in Figure 2. Groundwater levels in the Bunker Hill Basin are <br />continuing their annual summer descent, and will soon be approaching their seasonal low point <br />for the year. Water levels in Bunker Hill are approximately 1.7 feet greater as compared to July <br />of last year. Water levels in the Rialto -Colton and Riverside North basins are 19 and 22 feet <br />lower as compared to July of last year, respectively. The Riverside South Basin is <br />approximately 3 feet lower as compared to July of last year. <br />Page 79 <br />
