processes, including coagulation, flocculation, sedimentation,multimedia granular filtration, <br /> submerged membrane microfiltration,and chlorine disinfection. <br /> (See Appendix A for Map of the Service Area.) <br /> Water Rights <br /> The City of Cortez owns 4.2 cfs and diverts approximately 2800 acre feet of water per year. <br /> The City's drinking water system was originally constructed in 1960 and has undergone several <br /> subsequent upgrades. The treatment system was most recently upgraded in 2006 to include <br /> submerged•nnicrofiltration treatment,complementing the existing treatment processes. The <br /> upgrade has improved system performance and reliability. It also helps ensure compliance with <br /> increasingly stringent regulatory requirements,particularly for the removal of microorganisms. <br /> Finished water is stored in three above ground storage tanks that pressurize the distribution <br /> system and ensure adequate water is available during high demand periods. Each storage tank <br /> has a capacity of two million gallons(MG),and is located near the drinking water treatment <br /> plant. Two tanks are located at a higher elevation than the lower tank. The upper two tanks <br /> provide water to the Ute Mountain Ute Tribe. The lower tank provides water to the City of <br /> Cortez and Montezuma Water District No. 1. <br /> The drinking water supply for the City is from the Dolores River and McPhee Reservoir,the <br /> second largest reservoir within Colorado. The Dolores River is a tributary of the Colorado <br /> River, approximately 250 miles long, and flows through Colorado and Utah. <br /> Project Description and Alternatives <br /> The Public Works Department utilizes manual reads of our water meters on a monthly basis. <br /> This is done utilizing two (2) full time employees and assigned trucks. The meters are read using <br /> remotely mounted "odometers" or visual means for each meter in our system. This means all <br /> accounts must be physically visited every month. Currently, there are approximately 3,400 <br /> meters in our system. <br /> This method of collecting billing data is not cost effective. It is inefficient and can be <br /> problematic regarding human error, coverage of down personnel, timely reading/billing, and <br /> provides only static information. <br /> Human Error: There are several opportunities for making mistakes using this method—reading <br /> numbers,writing them down,and again during data input into the billing software system. <br /> Personnel Coverage: This system requires two employees to read our meters and, when one is <br /> sick or on vacation, coverage must be maintained. This takes resources from other programs. <br /> Timely Reading/Billing: Due to the nature of readings trickling in, bills are sent out four times a <br /> month. It takes four full weeks to read our entire distribution system. <br /> Static Information: The current model we are using only provides totalized flow data. We have <br /> no ability to track or identify types,times, and historical information on the meters. <br /> 5 <br />
