WEFTA continues to advance sustainable, community-driven water solutions in San Miguelito, El Salvador, where a network of five independent gravity-fed systems serves approximately 160 households. Recent progress has focused on the Mariogil sub-system, an important component in improving overall system balance and dry-season reliability.
Water Reliability
Targeted rehabilitation of the Mariogil spring catchment has led to increased water capture and improved flow from the source. By addressing inefficiencies at the intake, more water is now being effectively conveyed into the system rather than lost, helping to maximize available supply during periods of limited rainfall.
In parallel, replacement of the damaged Mariogil transmission line is significantly improving system performance. The new conveyance infrastructure is reducing leakage and interruptions while ensuring more consistent delivery of water from the spring to the storage tank and distribution network. This upgrade strengthens day-to-day reliability for households served by the Mariogil system.
Reaching a Key Milestone
A key milestone in this phase of work has been the enhancement of the interconnection between the Mariogil and Boledor sub-systems. With improved infrastructure and operational control, excess water from Mariogil can now be directed to the Boledor 2 storage tank when available. This added flexibility allows the system operator to better manage supply across service areas, supporting households in higher-demand zones and reducing localized shortages.
These improvements reflect WEFTA’s approach to strengthening existing systems through practical, high-impact upgrades. By increasing source efficiency, improving conveyance, and enhancing system integration, the San Miguelito water systems are becoming more resilient, better balanced, and more capable of meeting community needs—particularly during the dry season.
Work will continue in coordination with the local water committee to build on this progress and further improve reliability across all sub-systems.
