Preliminary estimates indicate <br />that, even if the existing diversion had to be replaced, the total cost would be no more than for the <br />alternative involving a new diversion (WRC Addendum Alternative 0-2 or Option B-2), <br /> <br />In conclusion, based on the preceding logic, MWE recommended retaining the gravity diversion <br />system; and the Town approved Option B-1 as part of the 1996 Master Plan and authorized <br />proceeding with the project as described herein, <br /> <br />IMPACTS AND PERMITTING <br /> <br />The present plan of utilizing the existing intake and pipeline route present essentially no new <br />impacts, Since the present point of diversion will not be moved, there should be no water <br />rightslflows impacts. All diversions will be made under existing adjudicated rights, with no revisions <br />foreseen. <br /> <br />The Corps of Engineers has been contacted regarding 404 permit requirements, Preliminary <br />indication is that construction can be undertaken routinely under a nation wide permit. <br /> <br />WATER METERS <br /> <br />The Town has agreed to calibrate all existing customer water meters and convert to billing under <br />a metered rate schedule, All new customers are required to have meters and will be on metered <br /> <br />7M80.039P:REPORT <br /> <br />11-4 <br />
