Integrated Water Resource Management: A Definition

• Management of the whole hydrologic cycle to achieve a coherent set of water resource policies and uses that balances all reasonable social, environmental, and economic needs in a sustainable way.

• Sustainability – “ … meeting the needs of the present without compromising the ability of future generations to meet their own needs.”

- World Commission on Environment & Development

What are the principles of IWRM?

• Recognize that fresh water is a finite but renewable and vulnerable resource, essential to sustain life, development and the environment

• Manage water resources based on more regional or watershed basis and needs of relevant stakeholders

• Preserve water sources and use water wisely

• Allocate water equitably based on input from all relevant stakeholders

Water Loss Management

• Research on acoustic leak detectors (M-LOG) in Connellsville, PA has resulted in >50% reduction in non-revenue water

• Two-thirds of the main breaks were preceded by evidence of pipe leakage

• Pressure management to reduce surges that lead to leaks

Piasa Creek Watershed ProjectImplementation Plan Benefits• Reduce sediment in watershed two times (6,700 tons per year) the

discharge of the new treatment plant by 2010.

• Reduce truck travel, air pollution, landfill space

• In Piasa watershed: reduced erosion, pollution, improved water quality, storm water control, fish and wildlife habitat, stream bank stabilization

• Land acquisition and conservation easements

• Wetlands restoration

• Educational programs

In the end, a cleaner Piasa creek and a cleaner

Mississippi River
