RIVERSIDE PUBLIC UTILITIES <br /> Board Memorandum <br />BOARD OF PUBLIC UTILITIES DATE: APRIL 9, 2018 <br />GENERAL MANAGER’S REPORT <br /> ITEM NO:17 <br />Summary of Riverside Public Utilities <br />Urban Water Production and Conservation Efforts / <br />Groundwater Level UpdateAs ofFebruary2018 <br />Conservation Efforts <br />RPU’s urban water production in February2018 was 4,237 AF. This is an increase from last Februaryby <br />1,699Acre-feetor about 67%. Despite this month’s increase in urban water productionas compared to <br />last February,RPUis still within the historical production range from2013to2017as shown in Figure 1. <br />Figure 1also shows that RPU’sprojected annual urban water production in 2018 is 66,800 AF which is <br />below the compliance target specified in SB X7-7(i.e. 20% reduction by 2020). The projections for the <br />2018 urban water production is based on current trends of increased consumption and can be affected <br />by the upcoming permanent water prohibitions, the return of the drought, and the proposed rate <br />increase. The projected annual urban water production is also below RPU’s current potable rights, which <br />potentially can maximize RPU’s passive assets by 5,200 AFthrough wholesale to Western Municipal <br />Water District. <br />Basin Groundwater Levels <br />Groundwater levels in the Bunker Hill, Rialto-Colton, and Riverside North basins are continuing to show a <br />long-term declining trend, while groundwater levels in the Riverside South Basin remain relatively stable <br />as shown in Figure 2. Groundwater levels in the Bunker Hill Basin are continuing to rebound from <br />summer pumping; however, water levels remain approximately 14 feet lower as compared to February of <br />last year. Water levels in the Rialto-Colton and Riverside North basins are 5 and 33 feet lower as <br />compared to February of last year, respectively. One of the likely reasons for the large February <br />difference in the Riverside North basin is due to the lack of rainfall and replenishing storm flows. By this <br />time last year, the Riverside area had received approximately 12 inches of rain, while this water year; the <br />Riverside area has only received about 2 inches of rain. The Riverside South basin is approximately 4 <br />feet lower as compared to February of last year. <br />Page 180 <br />
