Drinking Water and Integrated Watershed Management

by Paul D. Robillard, Ph.D., Executive Director
World Water Watch, Cambridge, Massachusetts
Member, World Water Center Advisory Panel

The task of supplying high quality drinking water to those in need is a great challenge and extremely rewarding for those organizations working with local communities when projects are completed.

The mission of the World Water Center (WWC) to act as a clearinghouse to facilitate partnerships for these projects is of great help to nonprofit organizations like World Water Watch. It is through these types of partnerships that coalitions of organizations can more effectively develop assistance to communities. WWC provides a much needed information network for the exchange of water supply projects and emerging water supply solutions between communities and nonprofits.

World Water Watch ( WWW ) assists communities and other nonprofits in the design and operation of water supply systems. With approximately 120 experts working with WWW on all aspects of water supply development, protection, treatment and remediation, WWW has worked with over 60 partner organizations on a wide variety of water supply topics.

Two aspects of this work should be emphasized. First, is the design of water supply systems that can be maintained by communities (Figure 1). Without proper maintenance water supply systems often fail after only a few years of operation due to a host of natural and mechanical problems which are common to all types of infrastructure projects. The classic example is failure of pumps in water supply distribution systems. Even “gravity systems” which do not rely on pumps can fail when pipelines are washed out in storms or sediment clogs lines.

There are many other ways in which systems fail. On the bright side, there are well established methods to maintain systems that ensure decades of reliable service. World Water Watch works with communities not only to develop new water supply sources but to design systems that include well proven maintenance components and procedures.

Integrated Watershed Management -- A New Concept

The second aspect of water supply systems that WWW supports is the development of “Integrated Watershed Management” (IWM) projects. IWM programs are particularly important to protect water supply sources and manage local surface and groundwater supplies in a sustainable manner.

IWM expands previous river basin and watershed limitations by emphasizing participation of all communities and private and public agencies in the allocation, use and management of water resources. Participation and representation of stakeholders in IWM programs are new, important and challenging. The words “integration” and “management” are key terms where water resource assessments and community needs are included in planning and implementing projects. Management includes protection and allocation of water sources, as well as treatment and remediation to facilitate water usage according to project objectives. Another new concept introduced into IWM relates to “sustainable” methods. Sustainability refers to the long-term management of water resources without depleting or contaminating supplies.

Initial efforts to establish IWM programs were based on themes from international forums, such as the Mar del Plata Conference (1977) and the International Conference on Water and the Environment (1992), which proposed guiding principles, such as:

  • Fresh water is a finite and vulnerable resource, essential to sustain life, development, and the environment.
  • Water development and management should be based on a participatory approach, involving users, planners, and policy-makers at all levels.
  • Women play a central role in the provision, management, and safeguarding of water.

From these basic principles, IWM planning and implementation have evolved to diverse interpretations and planning efforts. Consequently, definitions of IWM are quite varied. For example:

“IWM is a process which promotes the coordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems” (Global Water Partnership, 2000)

 

WWW Initiatives

One of World Water Watch’s major initiatives, AMZnet (Amazon Monitoring Network), includes the delineation of watersheds in the Napo River Basin in Ecuador for the primary purpose of protecting water supply source areas in an IWM context. Similarly, WWW is partnering with Jatun Sacha, a local nonprofit in Ecuador, and the Massachusetts Institute of Technology (MIT) to develop water supply treatment systems for eight communities in Ecuador. The MIT component will develop appropriate pre-treatment, course filtration, settling and storage, coagulation and precipitation, fine filtration and disinfection measures as needed at the village level as a model for wider applications. World Water Watch will develop an Integrated Watershed Management program to support sustainable solutions.

In addition, WWW will help provide solar energy sources for treatment processes where needed.

World Water Watch & World Water Center -- Looking to the Future

As World Water Watch becomes increasingly involved in projects and partnerships, the demands on the organization grow also. Our current priority community water supply system is for the village of Agato, Ecuador in the northern highlands.

If you are interested in supporting this project or other WWW activities please visit our website ( www.worldwaterwatch.org). All donations go to community projects. We also will keep you informed of project progress.

The number of people in the world without access to clean, reliable water supplies (Figure 2) is over one billion, yet the number of organizations trying to reach this huge needy population is small, so we must all work together.

We at World Water Watch appreciate the important and very much needed coordination that the World Water Center provides.

Scientific American : Confronting a World Freshwater Crisis

In its July 2008 issue a Scientific American special report concludes that the world is facing a freshwater crisis. “As demand for freshwater soars, planetary supplies are becoming unpredictable.”

“Overstretched freshwater supplies will increasingly influence the way we live. Existing technologies could avert a global water crisis, but they must be implemented soon,” say the authors, adding that:

  • “Global freshwater resources are threatened by rising demands from many quarters. Growing populations need ever more water for drinking, hygiene, sanitation, food production and industry. Climate change, meanwhile, is expected to contribute to droughts.
  • “Policymakers need to figure out how to supply water without degrading the natural ecosystems that provide it.
  • “Existing low-tech approaches can help prevent scarcity, as can ways to boost supplies, such as improved methods to desalinate water.
  • “But governments at all levels need to start setting policies and making investments in infrastructure for water conservation now.”

International Water Conference: Water Crisis Underlies World Food Crisis

At the recent 18 th International Water Conference in Stockholm the opening speaker, Jim Leape, told participants that the world's supplies of clean, fresh water cannot sustain today's "profligate" use and inadequate management, which have brought shrinking food supplies and rising food costs to most countries.

"Behind the world food crisis is a global freshwater crisis, expected to rapidly worsen as climate change impacts intensify," said Leape, Director-General of the World Wildlife Fund. "Irrigation-fed agriculture provides 45 percent of the world's food supplies, and without it, we could not feed our planet's population of six billion people." He warned that many of the world's irrigation areas are highly stressed and drawing more water than rivers and groundwater reserves can sustain.
