Grant Application Part 2 1. PURDY MESA LIVESTOCK WATER COMPANY 4110 PURDY MESA ROAD WIllTEWATER, COLORADO 81527 November 25, 1996 To: Water Conservation & Water Use Efficiency Block Grant Program The City of Grand Jct. gets its municipal water from Kannah Creek by virtue of a paramount right acquired by condemnation in 1911, upstream of all homes and irrigation ditches in the Kannah Creek-Purdy Mesa area. Over the years this right has been augmented by a supplemental decree and by purchased decrees and by purchased and developed reservoir water. The Kannah Creek area was settled in the 1880's and 90's by ranchers and farmers with the creek for a source of livestock, irrigation and domestic water. As the area developed the domestic water progressed from carrying water in a bucket from the creek to cisterns filled from the creek. After the City flowline was built a few homes in this area got their water from it. 1977 was a very dry year and after irrigation season was over (last of October) the City wanted all of the water, leaving no livestock water in the creek. The City allowed the residents ofKannah Creek a tap on the flowline with a 10 year contract for livestock and household use. The water was untreated except for chlorination. With some government help a pipeline was installed and this was the start of the Purdy Mesa Livestock Water Company. Approx. 1980 the City stopped chlorinating the flowline and the State Health Department required us to chlorinate our waterline. So we did. Over the years we received much correspondence from the City urging us to "seek our own source of water". About two years after our first contract expired and much negotiating, we arrived at a new 30 year contract in 1989. Among the stipulations, were develop our own source of water and build a water treatment plant. The State Health Department also required full treatment. After investigation several possibilities we settled on a Tube Membrane Ultra Filter system from US Filter Corp. which we installed and put in operation in Sept. of 1994. At the present time we are in debt $40,000 for the plant. It does an excellent job on turbidity but algae requires much backwash and cleaning, which wastes large amounts of water. We have built a 1 and 1/4 acre ft. pond which can be filled from a ditch, thus developing our own source of water. For this pond to be effective it needs a plastic liner. Also we need to install a tube settler in order to flocculate and settle the algae before the water goes thru the filter.
