City of Rifle Water Conservation Plan
Final Report -July 2008
Table 2-4 contains population and EQR growth projections and associated peak day
demand projections, based on the 1,024 gpd/EQR planning value for the "no
conservation" condition, as noted in Section 2.5. Peak day demand, and the opportunity
to reduce it, serves as the driver for water conservation planning in Rifle.

1. City does not actually track total system EQRs. This value is based on annual average metered
use of 388 gpolEQR for group of known 1-EQR residences and total annual system water use.
2. These values are based on 0.88 EQRs per housing unit estimated in 2005 times the number of
housing units added by 2006 and 2007.
3. This population value is estimated based on average population per housing unit times the number
of housing units added between 2006 and 2007.
