The Mortenson Center in Global Engineering (MCGE) at the University of Colorado Boulder trains engineers to work in partnership with institutions and communities worldwide to develop improved tools and methods to address global challenges.

Our program is based on the principle that students educated in Global Engineering will be prepared to solve engineering and science problems within the socioeconomic, environmental and political constraints often encountered in lower-resource settings. We combine education, research and partnerships to positively impact vulnerable people and their environment. Our vision is a world where everyone has safe water, sanitation, energy, food, shelter, and infrastructure.

Acacia Water is convinced there is enough water available for everyone. However, three factors are essential to address when approaching WASH related topics: 1) the quantity of the demand and the various user groups; 2) the preconditions set by the landscape and hydrological systems; and 3) the technical specific benefits and limitation of interventions. The power of our services lies in the integration of these elements and the ability to pass such knowledge to improve local capacity, both in a development program as well as emergency response.

Acacia Water distinguishes itself by collaborating closely with universities and research institutes. Together with implementing partners we translate the latest scientific developments in the fields of hydrology and environment into innovative and practical solutions to improve access to water resources and meet the Sustainable Development Goals.

WaterAid is one of the world’s best-known WASH implementers. Working in 25 countries in Latin America, Africa, and Asia, since 1981 WaterAid has helped bring clean water to 26.4 million people and reliable toilets to 26.3 million people.

A member of MWA since 2010, WaterAid is also one of the best-known advocates for WASH, globally and in the U.S.  MWA and WaterAid are leaders in the WASH advocacy coalition that has successfully raised the level of US government funding for international water, sanitation, and hygiene.

Today, among it many innovative programming initiatives, WaterAid is helping to build -term resiliency in global health. Leonardo Da Vinci said, “simplicity is the ultimate sophistication.” When it comes to global health, handwashing and hygiene are as simple as interventions come. Yet, the return on investment and health impacts are exponential.
