Our review of data leads to the conclusion that if <br />the odd /even watering ban is removed, peak demand would increase. <br />To illustrate the importance of keeping the odd /even ban to control peak demand, the <br />following analysis uses 2007 data from Cycle #3 (consisting of Routes 5, 6, 7, and 8). Cycle <br />#3 was selected because their winter quarter is Dec -Feb and summer quarter is June - August <br />(Cycle #1 winter quarter is Jan -Mar and summer quarter is Apr -Jun, Cycle #2 winter quarter <br />is Nov -Jan and summer quarter is May - July). <br />• Cycle #3 (Routes 5, 6, 7, and 8) <br />Total Winter Residential Consumption 23,891,000 gallons <br />Total Winter Customers 1,358 <br />Avg. Daily Winter Consumption Per Household 196 gallons <br />• <br />Total Summer Residential Consumption <br />Total Summer Customers <br />Avg. Daily Summer Consumption Per Household <br />101,146, 000 gallons <br />1,359 <br />827 gallons <br />Difference Of Daily Consumption Per Household 631 gallons <br />The above numbers show that each residential property on average uses 631 more gallons <br />every day during the summer months than they use in the winter. This is 4.2 times more than <br />winter consumption. <br />Watering lawns makes up a bulk of homeowners discretionary summer use. Other summer <br />related activities that consume water (washing cars, taking more showers, doing more <br />laundry, drinking more water) pales in comparison to typical daily watering of 1,000 gallons. <br />Watering Lawns <br />6 heads x 3 zones x 20 minutes <br />1,000 gallons <br />Washing Car (assuming <br />continuous flow) <br />15 gallons/ minutes x 20 minutes <br />300 gallons <br />Taking Shower <br />2.5 gallons /minute x 20 minutes <br />50 gallons <br />Washing Machine (2 cycle) <br />Typical Load <br />30 gallons <br />Drinking <br />In case you're very thirsty <br />5 gallons <br />
