Town Demands
Review of water produced at the Water Treatment Plant during the last 14 -years shows an annual
potable water demand of 210 acre -feet (af) with a low of 187 -af occurring in 2002. Non -
irrigation season demands average about 13 -af per month (0.21 -cfs) while peak usage occurs
during the month of July averaging about 28 -af (0.45 -cfs). The Town's interest in the number
one priority water rights (0.1 -cfs, or 72 -af /year) provides the only direct flow reliable yield
during drought conditions and is significantly less than the Town's demands. Portions of the
number three priority water right are available in dry conditions.
Water Treatment Plant (WTP)
Water delivered to the WTP can be fed directly from the LaVeta Pipeline or individually from
the North or South Lake. The pipeline to the WTP is under pressure, approximately 3 -psi, and is
lifted by a pump inside the WTP building to the filters. The plant capacity is designed to 1
million gallons per day (MGD) or approximately 1.5 -cfs.
Existing Storage
The North and South Lakes, LaVeta Pipeline, and Water Treatment Plant are shown on Figure 2.
No historic design drawings exist for the North and South Lake. The lakes have historically
been operated as an integrated supply with fills into the South Lake and with diversions
occurring from the North Lake. The North Lake has acted as the control structure for the
diversions into the WTP. The storage has been used to attenuate the fluctuating demands
associated with producing treated water within the WTP. The North Lake historically acted as
the first level of treatment by use of an intake tower that could control screening, intake depth,
and corresponding water quality of water within the profiles of the lake.
