EWB-USA's outward vision is of a world where all people have access to adequate sanitation, safe drinking water, and the resources to meet their other self-identified engineering and economic development needs. EWB-USA contributes with its partners to meeting the Millennium Development Goals set by the United Nations General Assembly on September 18, 2000 through capacity building. Capacity building is defined as ".. the building of human, institutional and infrastructure capacity to help societies develop secure, stable and sustainable economies, governments and other institutions through mentoring, training, education, physical projects, the infusion of financial and other resources, and most importantly, the motivation and inspiration of people to improve their lives" (Hatch, 2004). EWB-USA also endorses the Earth Charter. EWB-USA's initial inward vision is as a project coordination, funding, supervision and documentation organization that links university engineering schools with project opportunities, primarily in the developing world. EWB-USA also involves professional engineers who want to provide expertise on an as needed basis or work on projects. EWB?USA projects involve the design and construction of water, waste-water, sanitation, energy, and shelter systems. These projects are initiated by, and completed with, contributions from the host community, which is trained to operate the systems without external assistance. The objective of all these activities is not only to contribute to new and ongoing development projects in an effective way, but to expand the dimensions of experience for emerging and practicing engineers. It is our vision that this is a primary path to achieving a more sustainable world, without suffering the consequences of engineering projects that are socially, environmentally, or economically inappropriate. Engineers have a central role in building a sustainable future. Improving the lives of the 5 billion poor people whose main concern is staying alive each day is no longer an option for the engineering profession; it is an obligation.
