The project takes an integrated approach to the rights to water and sanitation, as well as the right to clean drinking water, all recognised by the UN as essential conditions for the protection of human rights overall. The project's work also aligns with Objective 6 of the UN's Sustainable Development Objectives, which calls for universal access to water and sanitation and for the sustainable management of water resources.

The project has a duration of four years, a period that will conclude in December 2017.

The chief results attained thanks to the range of actions carried out under the project include:
  • Joint tripartite management of drinking water supply systems by an association of municipalities (drinking water infrastructure for several municipalities).
  • Management of the waters of the Lempa River, an important source of water (37%) for the San Salvador Metropolitan Area.
  • Implementation of a trans-border water management policy involving three countries.
  • Bolstering of local water management capacities as follows:
Strengthening of tripartite water management: city councils, municipalities and Water Systems Administrative Boards.
Improvements in the technical capacities of city councils and the MTRL.
Improvements in local infrastructure.

The AMB's technical contributions: The main areas in which the AMB has offered technical collaboration in the project are as follows:
  • Identification of the proposal and selection of strategy.
  • Technical consulting to help improve the region's drinking water systems.
  • Transfer of knowledge to help train municipal and inter-municipal staff in the improved management of urban drinking water supply systems.
  • Remote support for the technical management of the project.
  • Provision of guidelines for the diagnosis, monitoring and management of drinking water systems, and support in the creation of a local set of guidelines.
