"11.6.4 There was interest among some of the Basin Roundtables to further enhance the flows for
environmental and recreational purposes beyond the instream flow program, and in developing new
and creative mechanisms to achieve this goal. The key to doing this lies in involving all key
stakeholders in this discussion - environmental interests, recreational advocates, agriculture,
municipal, and industrial. In addition, it is imperative that these stakeholders strive for balance in
how this goal is achieved. In developing new water projects, this [ISF] Program also was identified
as having an important role to play. CWCB should identify stream segments or ecological areas for
flow prioritization or enhancement. Working through the Basin Roundtable process, the Division of
Wildlife (DOW), and other interest groups, the state could begin to develop an objective and
reproducible framework for evaluating, quantifying, and prioritizing environmental and recreational
water goals. This program could build from the existing authorities of the CWCB instream flow
program and the "conserve, protect, and restore" approach brought forth through many of the SWSI
Basin Roundtable discussions."

Recommendation: Staff gives a high recommendation to this project because it will develop
information to educate water interests regarding ISF and Natural Lake Level Program.

Water Conservation Planning Program

1. Utility Water Loss in Colorado

Beneficiary /G ran tee/Co n tracto r:
Amount of Request:

CWCB, Various
$150,000

Ranking: High

Product Produced: The purpose of this project is to develop, implement, and refine a standard
reporting methodology for utility water loss in Colorado. "Water loss" is the current industry
standard ternlinology for unaccounted for water or line loss. There is currently little data on water
loss in the State and what data does exist has been developed in such a way making it virtually
impossible to adequately compare loss between agencies and to determine if loss is significant.

The International Water Association (IW A) and the American Water Works Association (A WW A)
have developed a standard methodology for determining water loss for municipal water providers.
This methodology has not been widely adopted or implemented in Colorado.

The project will start by first implementing the current IW AI A WW A water loss procedures for a
cooperating municipal water provider in Colorado. This implementation will result in the
quantification of water loss for this utility. Based upon this implementation experience, the project
team will create a set of water loss analysis and reporting tools for use by providers in Colorado.
The research team plans to take advantage of a number of public domain tools that exist for utility
level water loss evaluation. Once these tools have been developed, they will be tested on a second
Colorado water utility. Again the IW AlA WW A water loss methodology will be implemented, this
time using the water loss analysis reporting tools specific to Colorado. Based on the experience
from this second implementation, the analysis and reporting tools will be refined and finalized into a
standardized form for use by other Colorado water providers.

Water Planning Relationship: This project would seek to support and validate the water
conservation measures findings, as laid out in the matrix of measures, developed by the
Conservation & Efficiency Technical Roundtable established in Phase 2 of the Statewide Water
Supply Initiative, coordinated out of the CWCB's Intrastate Water Management & Development
Section.
