The total annual pumping was divided by the <br />number of residential connections to estimate the per unit demand on an average day. A similar <br />calculation evaluated the per unit demand on the maximum day. The City’s average day demand from <br />2013 to 2015 was 303 gallons per unit, and the maximum day demand was 911 gallons per unit. These <br />values are used to estimate the capacity for development. <br /> <br />Development Capacity <br /> <br />To determine how many additional units can be supported on the existing system, both water storage <br />and supply were considered. Results show that with the addition of Well No. 6, the water supply will be <br />sufficient for approximately 1,650 average-use homes after Mattamy is connected, while water storage <br />should be upgraded upon the addition of 104 average-use homes. Therefore, water storage will be the <br />limiting factor in terms of development. Table 3 summarizes the predicted capacity after the Mattamy <br />development is fully connected. <br /> <br />Table 3: Development Capacity <br />Water Availability Water Towers Production Wells <br />Total Capacity 2,000,000 gal 6,264,000 gpd <br />Remaining Capacity 295,000 gal 2,304,000 gpd <br />Mattamy Demand* 264,000 gal 793,000 gpd <br />Capacity Available 31,000 gal 1,511,000 gpd <br />Number of Additional Residential Units 104 units 1,650 units <br /> <br /> K:\02029-820\Admin\Docs\Water System\Appendix B - System Capacity.docx
