Typical wells in the area such <br />as serve Keenesburg have 3 capacity of 50 to 75 gallons per minute <br />using a six inch casing. Larger wells have been drilled and provide <br />additional capacity. However, well casings of 15 inch size can only <br />be expected to yield 100 to 150 gallons per minute. The deep well <br />system has relatively high operation and maintenance costs and has <br />other operational problems. The high costs result from difficulty in <br />replacing pumps, pumping inefficiency due to low capacity versus <br />high pumping head, high power costs required for pumping, high first <br />cost of installation and low capacity and depth of aquifer. Although <br />long-term needs may not be met because of the limitations and restric- <br />tions of the groundwater basin, immediate and near future needs may <br />be satisfied by this source at this time if the Town uses it to <br />supplement its existing supply. <br /> <br />Exhibit V-4 is taken from a Sanitary Sewer Report by the Colorado <br />Department of Health on Keenesburg. It provides information on the <br />existing deep well water. It may be assumed that this would be <br />typical of the water obtained from deep wells in the Hudson area. <br /> <br />In reviewing Exhibit V-3, it appears that deep wells should be located <br />to the northeast of Hudson to limit the depth of the wells through the <br />aquifer. However, it is anticipated that wells can be drilled in any <br />direction from the Town. Minimum well spacing should be one half <br />mile, and preferably at greater separation for sustained yields. <br /> <br />The procedure for the Town to obtain water from deep wells has been <br />reviewed with the Colorado Division of Water Resources. The Town <br />may file for water under properties owned by the Town under the <br />provisions of Senate Bill 213. A well permit application must be <br />filed along with an owners affidavit. This may be done for water <br />under property where the water has not been already appropriated. <br />On properties not owned by the Town and where water has not been <br />appropriated, the property owner can sign and have notarized an <br />affidavit consenting to allow the water to be used by the Town. <br />It is assumed that the Town can negotiate with nearby property <br />owners to obtain well sites and to obtain adjudicated water for <br />its use. <br /> <br />v - 8 <br />
