CWCB Water Conservation Planning Grant Application

City of Rifle

supplies and infrastructure, analysis of potable system, reliability, historical
potable water demand analysis and future projections, and projection of potable
system infrastructure needs and costs through 2025. It al~o includes a financial
spre'adsheet for projecting required rate and fee increa~es over time to fund
capital projects in the potable system. For water conservation planning purposes,
the spreadsheet will be extended to include operations and! maintenance (O&M)
costs, purchased water costs, and raw water system costs; it will be used in place
of standard CWCB worksheets for determining the effect of conservation
measures and programs on the total cost of water service. I An additional note is
that future water demands, infrastructure requirements, and costs were projected
based on an anticipated annual growth rate in water demadd of 4.5%. The most
recent projections for annual growth are higher; howevet, for the purposes of
cost..benefit analysis in this Plan, 4.5% annual water demarld growth will be used
to avoid the need to revise the baseline infrastructure and tost projections of the
"no conservation" case. I

For this project, the following sub-tasks will be required to augment work
already completed for Steps #1 through #3 as part of the Water Master Plan:
I
o Past and present water conservation efforts and et~ects, if any, will be
summarized. It is anticipated that only passive conservation has occurred to-
date. [City stafJ) I
o More detailed evaluation of existing water use by sector, per capita, per
I
household and by season with comparison to national1regional values. The
goal is to establish a basis for identifying and evaluating conservation
I
measures and programs (Steps #5 and #6). [ConsultantJ/
o Compilation and review of data related to water metering coverage, meter
,
conditions, water rate/fee structure, and water billing process. This
information will help identify and evaluate consertation measures and
programs (Steps #5 and #6). [Consultant/City stafJ) I
o Analysis of existing, and rough projection of future, lfixed and water-use-
dependent O&M costs for the water and wastewater systems. This will allow
quantification of cost-savings benefits of conserv~tion measures and
programs (Step #6). [City sta./flConsultant} I
o Identification of future water supply costs (Le. legal and volume costs to
purchase augmentation water) to allow quantification 10f water acquisition
benefits of conservation (Step #6). [City stafJ)
o Compilation and analysis of existing raw water use, infrastructure, and O&M
costs and development of future projections. [Consultant}
o Projection of future wastewater treatment capital project!costs. [ConsultantJ
o Incorporation of potable system O&M and water acquisition costs, raw water
I
system costs, and wastewater system costs into existing capital planning
financial spreadsheet to allow economic evaluation of conservation effects
(Step #7). [Consultant}

c. Task 02: Identify Water Conservation Goals (Planning Step #4)
[Task responsibility: 50% City staff /50% Consultant} I
Work under this task will establish an initial estimate of a "blest-fit" overall water
conservation goal for the City. It is envisioned that this initial estimate will be
developed by considering the following: I
o Degree of City Council support for water conservation (initial meeting with
Council to be held as part of this task) [Consultant/City StafJ)
