• A listing of the peak daily treated water demand for each month from January <br />2002 to December 2006 was created. <br />• Using this list, the peak daily treated water demand for each month was <br />normalized to the average annual peak daily treated water demand f or each of <br />the five years of record (2002, 2003, 2004, 2005, and 2006). <br />• An average of the normalized peak daily treated water demands was taken using <br />all five years of record to develop an average normalized peak daily water <br />demand f or each month of the year into the f uture. <br />• An estimate of future annual peak daily treated water demand was forecasted <br />using a product of the ratio of the observed annual peak daily treated water <br />demand to total annual treated water demand for 2004, 2005 and 200b and the <br />estimated f uture total annual treated water demand presented in Table 4. <br />• The estimated peak day treated water demand for each year, as presented in <br />Table 4 was used along with the average normalized peak daily water demands <br />for each month, to forecast future peak daily treated water demand for each <br />month f rom 2007 through 2017. The resulting f orecast is provided in Figure 3. <br />Figure 3 -Current and Future Daily Peak Treated Water Demand <br /> 18 <br /> 16 <br />~ <br /> <br />`~ 14 <br />~ <br />p „ <br />N <br />12 <br /> o <br />a ~ 10 <br />s <br />~ ~ <br />° <br />8 <br />~ 0 <br />~ ~ 6 <br />as <br />`~ <br />~ 4 <br />~ <br />L <br />~ 2 <br /> <br /> 0 <br /> <br /> N M ~ h ~ t o I~ 00 O O ~ N M r h ~ t 0 t o I~ <br /> O O O O O O O O ~ ~ ~ ~ ~ r r r ~ <br /> C C C ~ C C ~ ~ ~ ~ ~ ~ ~ C C U U <br /> t~ t~ t~ t~ t~ t~ ~ ~ ~ ~ ~ ~ ~ t~ t~ <br /> <br />> > > > > > > <br />> <br />> > > > > > > <br />Q Q <br /> ~h ~h ~h M M M M N N N N ~ ~ ~ ~ r ~ <br /> M M <br />Based on this forecast, it can be seen that summertime daily demand will climb above <br />current operational treatment plant capacity (of 12.3 mgd) by 2012. By 2017, peak daily <br />treated water demand is f orecasted to reach 16 mgd or about 60 % more than the peak <br />treated water demand of 10 mgd in 2005. Water conservation measures and programs <br />will need to be developed to address this expected treated water demand and <br />infrastructure limitation. <br />Cih~ of Brighton Wnter Cofiservntiofi Plnri 12 <br />
