VII A i I. H I IJ I R Y 1. 1� E RIVERSIDE PUBLIC UTILITIES Board Memorandum PLJIBLIC U r I L I T I E S BOARD OF PUBLIC UTILITIES DATE: November 5, 2018 GENERAL MANAGER'S REPORT ITEM NO: Summary of Riverside Public Utilities Urban Water Production and Conservation Efforts / Groundwater Level Update As of September 2018 Conservation Efforts RPU's urban water production in September 2018 was 6,531 AF. This is an increase from last September by 239 AF or a drop in conservation of 3.6%. Weather conditions showed a dry September month with respect to the 0.06 inches of rainfall from September 2017. September of 2018 was warmer by about 3.0 degrees compared to last year. RPU is still within the historical production range from 2013 to 2017 as shown in Figure 1. Figure 1 also shows that RPU's projected annual urban water production in 2018 is 64,150 AF which is below the compliance target specified in SB X7-7 (i.e. 20% reduction by 2020). The projections for the 2018 urban water production is based on current trends of increased consumption and can be affected by the permanent water prohibitions implemented by the State and/or the return of drought conditions. The projected annual urban water production is also below RPU's current potable rights, which potentially can maximize RPU's passive assets by 6,260 AF through wholesale to Western Municipal Water District. Basin Groundwater Levels Groundwater levels in the Bunker Hill, Rialto -Colton, and Riverside North basins are continuing to show a long-term declining trend, while groundwater levels in the Riverside South Basin remain relatively stable as shown in Figure 2. Water levels in Bunker Hill are approximately 2 feet lower as compared to September of last year. Water levels in the Rialto -Colton and Riverside North basins are 7 and 18 feet lower as compared to September of last year, respectively. The Riverside South Basin is approximately 3 feet lower as compared to September of last year. Page 97
