Delivering safely managed water to schools and a maternity center in Zambia
Through strategic site selection in the Zimba district, seven successful wells provided substantial improvements to water security. The number of schools and clinics without waterpoint was reduced by 30%, while 11,675 people gained or regained improved access to clean drinking water. The strategic partnership in this project also resulted in one new water point, which enabled a maternity clinic’s opening and a delivery ward to serve 25,000 people. Read more.
Addressing the household water portfolio improvement in Ghana
- Salinwia – 408 locals benefitted from the borehole. Households here are also farmers, and the water well would be beneficial, especially for year-round subsistence farming.
- Zagsliari – positioned between two towns, less than 1 km (0.62 miles) apart, families here are larger, and approximately 150 locals benefited from the borehole and filtration system.
- Zangum – a peri-urban town with approximately 170 compound houses. An average of 1,020 benefited directly or indirectly from the borehole. Read more.

Building blocks of success in Uganda
- Redefining the connections between WASH, skill-building, and gender empowerment by measuring youth and women empowerment for long-term sustainability.
- In GWB’s Uganda water project, an estimated 20 villages have safe water, directly providing water security to the communities. Approximately 6,500 villagers are now water secure, which was achieved by citing water wells in 10 villages. One school has WASH access and 27 Acholi people are trained. Half of the 27 Acholi people were also project participants in the 2018 expedition by the same project investigator and his team. Five new wells benefited an estimated 3,080 villagers, and the nine repaired wells benefited an estimated 6,920 villagers. Drilling eight more wells benefitted 3,010 villagers and 1,200 primary school students. This project was unique in its approach to empower local youth and women to earn livelihoods and enable girls to receive an education. The team will return in February 2025 to continue building upon its past two projects. Read more.
Alleviating water-related climate vulnerability in Nepal
Two rural communities, Phortse and Khumjung-Kunde, in the Sagarmatha National Park, Nepal reduced their long-term water and climate vulnerability. These communities were identified due to their need for improved water security. The community members raised considerable funds (Phortse raised >US$100,000) additionally toward the project to support their clean-water initiatives. Both communities asked for the project team’s assistance to determine what options were best for their village, for example, the placement of the system needed in order to be resistant to the impacts of climate change and earthquakes.

Providing risk reduction toward tsunami and seismic vulnerability in Nepal and Indonesia

Tsunami Preparedness
In Indonesia, the team took measurements on six islands to acquire data, excavated eight paleotsunami trenches, and documented imbricated beach rock boulder deposits at 18 different sites in an area with a population of about six million. They assisted these communities and partners develop a tsunami early warning system and evacuation plans. This strategy resulted in the 20-20-20 principle being adopted by local governments and communities. In most cases, if the ground shakes for 20 seconds, it indicates a major earthquake. Residents have 20 minutes before a tsunami reaches the coast, and the results showed that people must evacuate to an area 20 meters above sea level to avoid the tidal wave. 20 meters elevation is above the effects of historical tsunamis. The team also identified substrates that could become unstable during ground shaking by earthquakes, likely resulting in structural damage to buildings. This finding was shared with the local authorities and communities. Read more.
Earthquake Early Warning (EEW)
Due to large earthquakes, a dense population, and vulnerable residential buildings, Nepal ranks among the countries with the world’s highest seismic risk. In 2015, a magnitude 7.8 earthquake (Gorkha earthquake) hit Nepal, claiming about 9,000 human lives and leaving many homeless. Yet, in the future, even larger earthquakes are expected to occur. This GWB project aimed to test the feasibility of Earthquake Early Warning (EEW) systems in central Nepal by establishing a low-cost, real-time earthquake monitoring system based on Open Sourced EEW technology. The project’s greatest impact has been on transferring knowledge and technology to local authorities for ongoing monitoring and EEW issuance. Read more.
