The study looked at how rural communities in Eritrea can maintain their water supply and sanitation systems. They found that involving the community in decision-making is crucial for long-term success. People need to be willing to pay for the water they use to cover costs. In Berik Sub-Zone, committees with diverse members oversee the system, collect small fees, and ensure regular maintenance. Meetings, monitoring, and good record-keeping also help keep the system running smoothly. Cooperation with local and national governments is key to keeping the water supply and sanitation system sustainable.
