Water and Energy - Draft Report of the GWRC Research ... - IWA

The research was sponsored by AwwaRF, EPRI-CEC, and East Bay Municipal Utility District
and published by AwwaRF. The project concept was partially driven by electric utility
deregulation, which presents an opportunity to lower energy costs for water utilities that can
optimally manage and control their systems. ‘Quality and supply’ are the boundaries under
which the optimization problem can be initiated and solved.
A Total Energy and Water Quality Management System (Ladner, Talley, and van Buskirk,
1999)
The research was sponsored by AwwaRF and EPRI-CEC and published by EPRI. The report
develops a generic model for an energy and water quality management system (EWQMS) for the
water community, and defines standard specifications for software applications required to
minimize energy costs within the constraints of water quality and operation goals. Eleven
drinking water utilities provided input to the requirements of the EWQMS.
Implementing a Prototype Energy and Water Quality Management System (Jentgen et. al.,
2003)
AwwaRF and EPRI introduced the concept of an EWQMS in a February 1997 report. The report
defined an EWQMS as a collection of application software programs that provide information
used to develop plans that solve water quality, supply, and energy management problems. Users
receive information and prepare plans for daily decision-making. These plans are developed
using optimization and simulation techniques embedded in the software programs. The report
describes the implementation effort at Colorado Spring Utilities.
Optimizing Operations at JEA’s Water System (Jentgen et. al., 2005)
The research was a tailored collaboration project with JEA Water and Wastewater, which
extended the experience of the previous EWQMS projects to software implementation,
installation, testing, calibration, and daily operations of an optimization system. The project
expanded previously developed software for optimized system controls of aquifer resources
(OSCAR) that was developed to minimize cost while improving water quality and better
managing water resources; describes benefits of optimizing operations and includes functional
software specifications; and documents experience and lessons learned in the implementation,
calibration, and operation of the OSCAR software.
Quality Energy Efficiency Retrofits for Water Systems (1997)
The project was funded by the California Energy Commission, AwwaRF and EPRI-CEC and
published by EPRI. The manual provides information that can help operations and engineering
staff in water supply facilities successfully implement common energy efficiency improvements.
The manual’s scope is limited to project implementation issues.
Best Practices for Energy Management (Jacobs, Kerestes, and Riddle, 2003)
The research developed and documented a consortium benchmarking process for water utility
application, and tested the application of the process in an energy management benchmarking
study. The project resulted in documentation of more than 20 best practices in energy
management and a survey tool for utilities to use in assessing and planning their own energy
management. The best practices included a description, metrics to measure them, obstacles in
applying them, and benefits achieved in using them.
