<br />Feasibility Report for Improvement of Paonia's Water Supply System
<br />Town of Paonia
<br />April 21, 2000
<br />
<br />5. WATER SUPPLY FIRM YIELD
<br />
<br />5.1 Existing Raw Water System
<br />
<br />The Town's water supply system includes a complex network of natural springs, raw and treated
<br />water transmission lines, treatment plants, treated water storage, reservoir storage, and a metered
<br />distribution system, Figure 5.1 shows the location of the springs and pipelines that supply
<br />Paonia with its raw water. Figure 5.2 is a schematic of the water supply system that illustrates
<br />the relationship of water rights and transmission and storage features,' ,t-

<br />The Town's water system is divided into two separate systems, whicff:':-~ssentially opera~';l
<br />independently from each other, The lower system serves most of the r,~sideriK~~6,r:~side wit,hin
<br />the Town limits and the upper system serves most of the private pipeline coIiiPanie$;' custorhers
<br />living outside the Town, and the newer subdivisions loc<t!ed.at higher elev~ti9.H~:;}Yithin the
<br />Town, Each system has its own treatment plant, treated~ater storage, transfuission and
<br />distribution system, and water supply springs, There is a 2~mch-cliameter pipeline that can be
<br />used to feed water from the upper system to the lower system, During emergencies, the lower
<br />system can also be used to supply water to the upper system, but~t reduced service pressures,
<br />
<br />Water for the upper system comes from the LakeFork Springs and the three German Creek
<br />Springs (See Figures 5.1 and 5.2). Raw water transmission pipelint;:s in the upper system include
<br />. , -., ~
<br />the Beaver Dam Ditch Pipeline and the German Spring~ PipeIme, Water treated at the upper
<br />treatment plant can be either stored in~2-millioIi-gallon (MG), welded-steel storage tank, where
<br />it is delivered on demand to the upper:systemdistributionsystem, or delivered to private pipeline
<br />companies through the Stewart Mesa or Dry Gulch Pipeline, Filter backwash water and excess
<br />treated water that cannot b~ delivered to storag~ pr other pipelines is spilled to Dry Gulch at the
<br />upper trealIi1ent plant. l'htl total direct flowv.:ater right of the upper system springs is 4,5 cfs,

<br />10Q,percent of the flow, During the rest of the year, 75 percent of the flow is diverted to Paonia
<br />and~ihe remaining 25 percent is diverted to Bone Mesa. Treated water from the lower plant is
<br />store.(i in a I MG concrete storage tank near the lower treatment plant or in a smaller 0,5 MG
