<br />. <br /> <br />PROJECT DESCRIPTION <br /> <br />Thi.s supplement to the 1976 Water Supply Master Plan Report as prepared <br />by Wright-McLaughlin Engineers will address the needs of the Town of Hotchkiss <br />in replacing the deteriorating treated water flow line and potential of <br />generating 28 Kw of electricity in a portion of the raw water flow line. This <br />supplement to the Water Supply Master Plan Report as prepared in 1976 is not <br />adequate to provide all of the information required to make technical or <br />financial decisions without a full knowledge of the contents of the Water <br />Supply Master Plan Report as prepared in 1976. Copies of the 1976 Master <br />Report are scarce but should be on file in the Hotchkiss Town Hall. <br /> <br />The Water Supply Master Plan Report as prepared in 1976 recommended that <br />the Tmm of Hotchkiss proceed wi th improvement of their waterworks system in <br />three phases. Phase I has been completed in accordance with the recommendations <br />and this supplement will touch only upon those recommendations as proposed <br />in Phase II in accordance with priorities that have been developed by the <br />Board of Trustees of the Town of Hotchkiss and intiate a new recommendation <br />brought about by the high price of electrical power. <br /> <br />The philosophy of the Water Supply Master Plan Report of 1976 was,to <br />provide capital improvements to the water system as became necessary so that <br />existing residents would not pay for future growth which mayor may not <br />materialize, This supplement to the Water Supply Master Plan Report will <br />continue that philosophy in its recommendations. <br /> <br />Treated Water Transmission <br /> <br />Prior to the completion of Phase I of the waterworks improvements project, <br />water was stored in the 0.4 MG clear water storage and excess water spilled <br />from the tank in the overflow. The height of the 0.4 MG clear water storage <br />is 27 feet, 27 feet of head will produce 11.69 psi. In the construction of <br />Phase I of the waterworks improvements an altitude valve was built into the <br />piping of the 0.4 MG clear water storage and now when the tank is full, water <br />backs up the treated water transmission line to the water treatment plant <br />which places a pressure of 89 psi on the lower portion of the treated water <br />transmission line. The additional 77 psi on the deteriorating cast iron <br />line has created leakage problems in the transmission line. <br /> <br />The alignment of the existi,ng treated water transmission line traversed <br />on a diagonal through fields wi thout regard to property lines, allowi ng the <br />construction to take place with the smallest quantity of pipe material re- <br />quired for continuous connection from the water treatment plant to the O.~ MG <br />clear water storage. The Town of Hotchkiss has an easement for the location <br />of the existing water line and the replacement of or maintenance of same. <br />However; the Town of Hotchkiss is still obligated to return the property to its <br />original condition during maintenance or replacement of the line. Therefore, <br />a new alignment of the transmission has been determined, the new alignment will <br />traverse along property lines or County Road rights-of-way which will allow for <br />better planning of the property through which the old line presently traverses <br />on a diagonal. The alignment of the proposed new water transmission line inter- <br />sects the alignment of the existing water transmission line in four places (as <br />shown on Exhibit A of this supplement) and it is proposed that the Town of <br /> <br />] <br />
