WeTu

Innovation hub with sustainable impact

The social enterprise WeTu offers sustainable solutions for clean water, energy, and mobility.

WeTu is a social enterprise founded by Siemens Stiftung in Kenya that works on innovative solutions for supplying energy and drinking water in communities on Lake Victoria. In addition, the company is deploying the first-ever electric vehicles specifically developed for rural Africa. When combined with social and ecological business models, these solutions are improving living conditions in the region, creating jobs, and establishing new economic opportunities.

Project

The opportunity of social enterprises for the region

“WeTu” means “ours” in Swahili and is the brand name of the social enterprise WeHub! Lake Victoria Ltd. The core business of the 100% owned subsidiary of Siemens Stiftung is based on renting out solar-powered fishing lanterns, distributing clean drinking water, and providing e-mobility solutions. The objective is to sustainably finance the operational business of the social enterprise, as well as the maintenance and upkeep of the technical facilities, from the revenues generated. Profits remain within the company and serve to further expand and strengthen the associated positive societal impact.

WeWater

At the WeTu hubs, raw water from Lake Victoria is purified following the latest standards. A multi-stage process includes ultrafiltration using membrane technology as well as UV disinfection. Depending on demand, up to 4,000 liters of hygienically safe drinking water per hour can be treated at one site. Through an ATM system, the safe drinking water is available around the clock at several dispensing points in the community. Payment is straightforward and completely cashless via Mobile Money, allowing customers to conveniently top up their credits anytime via mobile phone.

WePower

The WeTu Hubs are solar-powered charging stations providing power for sustainable energy solutions. Based on sharing economy, WeTu rents out lanterns and batteries for electric vehicles, takes care of charging and maintaining the products, and thereby operates an environmentally friendly reuse and recycling process. Many fishermen at Lake Victoria use lanterns with lead-acid batteries, which sink to the lake bottom during storms and pose a high environmental burden. In contrast, WeTu offers lanterns with lithium-ion batteries that are robust, long-lasting and buoyant.

WeMobility

WeTu is testing electric vehicles specifically designed for use in rural areas. These environmentally friendly vehicles are intended to provide a long-term alternative to conventional modes of transportation. As part of a sharing economy model, regional traders, fishermen, farmers, and small businesses can utilize these vehicles to increase their reach. Assembly and maintenance take place in local workshops, thereby creating a regional value chain. The batteries of the electric vehicles are charged with solar energy and can be conveniently swapped at the hubs.

Education

WeLearn: For a sustainable future in rural Kenya

To combat the high youth unemployment in the region and attract qualified workers for sustainable professions, Siemens Stiftung, in collaboration with WeTu, provides hands-on training for technical vocations to young people at the company’s location. Through four-week courses, participants learn skills such as operating solar pumps, charging infrastructure, and solar power systems. A special focus is placed on promoting women, who make up 50 percent of the participants. By involving local experts as trainers, a sustainable impact is achieved within the communities.

Impact

By now, over 60 full-time employees are working daily at 16 locations to provide services to the local population in the region. In this process, WeTu works closely with local authorities – with particular consideration for environmental and health issues. To reach more people and scale its impact, WeTu is continuously expanding its offerings in collaboration with numerous local and international partners.

Current pilot projects at the hub

WeCollect

WeCollect collects e-waste from the community, tests and disassembles the devices in a pre-treatment facility before the components are transported to recycling or disposal facilities. Solar products are repaired. By reusing, reducing, and recycling e-waste, valuable resources are recovered.
