In late September, our team traveled to Zanzibar for two weeks of hands-on training in the operation and maintenance of solar-powered water systems (SPWS). With rapid growth in solar water infrastructure across the islands, the need for skilled technicians has never been greater.
The training brought together 40 technicians from the Zanzibar Water Authority (ZAWA)—representing a wide range of experience levels, from certificate holders to university graduates in geology and related fields. Each cohort spent the week combining classroom learning with practical, field-based sessions that bridged theory and application.
Midweek, participants visited a nearby SPWS site to identify key components, assess maintenance needs, and apply the tools and checklists introduced earlier in the course. The field visit offered a valuable opportunity to strengthen diagnostic and problem-solving skills, reinforcing the importance of regular maintenance and system monitoring.
As with other Global Water Center training programs, the course content was tailored to reflect Zanzibar’s local environment and water delivery systems. While sessions were initially planned to be conducted primarily in English with some materials in Swahili, it soon became clear that using Swahili throughout would make the training more engaging and the concepts for accessible. Lead facilitators Kogi Chege and Martin Sanga adapted in real time, revising activities and explanations to ensure every concept resonated with participants.
By the end of the trainings, the energy and collaboration in each group was unmistakable. Debates over system design and maintenance strategies filled the rooms with laughter and insight, as participants shared their own experiences, and their new ideas for solar powered water systems.
One trainee, Rashid, reflected after receiving his certificate:
“I thought I knew more than I actually did, but now I feel like I know everything I need to know to be out in the field and make a difference. I learned so much information, but the more important thing is I learned how people should be taught—and for that I’m grateful.”
This training—developed by Global Water Center in partnership with Oikos and GIZ—underscored the power of adaptability and learner-centered design. As Zanzibar continues to expand its solar energy infrastructure, these newly trained technicians will play a key role in ensuring that every solar-powered water system delivers reliable, sustainable, and safe water to the communities it serves.
