<br />The plant is generally run on a continuous basis. For the months of October through <br />May, the number of units online is limited to two or three units with the net production <br />capacity reduced to meet the lower water demands during the off-peak season. This is <br />accomplished by the use of variable speed pumps on the plant supply line that adjust <br />the flow rates to the filters to meet projected water demands for the day. During the <br />months of June through September, the number of micro-filtration units online typically <br />varies from three to four with continuous plant operations 24 hours a day. <br /> <br />Assuming the current population is 7,200 persons and maximum-day flow is 2.9 MGD, <br />the calculated maximum-day-per-capita flow is 403 gpcd. In the future, we expect to <br />see a slight reduction in these values. For planning purposes, the maximum-day-per- <br />capita flows are anticipated to be in the range of 375 gpcd by 2030. Based on 30/0 <br />annual growth and the planning numbers presented herein, we estimate the current <br />WTP will have adequate capacity until City demands equal 3.87 MGD (4.5 filters at 0.86 <br />MGD per filter) or until 2016. At that point in time, we anticipate replacing the filters with <br />higher efficiency filters, adding two additional filters and constructing a backwash <br />recovery system. This will increase the capacity of each filter to approximately 0.9 <br />MGD. Thus, the City should anticipate a filtration capacity of 6.5 micro-filters at 0.9 <br />MGD per filter for a total capacity of 5.85 MGD. <br /> <br />The scheduling of water system improvements to meet water demands for the projected <br />number of taps is very dependent upon the projected population growth rate, actual <br />water usage and existing system limitations. A high population growth rate or high <br />water usage rate per tap will require the expansion of the water system improvements <br />over a shorter period of time whereas a low population growth rate or low water usage <br />rate per tap allows the improvements to be phased over a longer period of time. <br /> <br />Clear Water Solutions, Inc. <br />City of Fort Lupton <br />2007 Water Conservation Plan <br /> <br />28 <br />
