The GoAL WaSH project (Governance, Advocacy and Leadership in Water, Sanitation and Hygiene) was launched in Mongolia in 2010, in response to evidence that improved governance of the sector was a key requirement to accelerate achievements of the water and sanitation Millennium Development Goals (MDGs). The project provided resources to support sector coordination, sectoral reforms and developed a management model for water supply and sanitation services in rural areas. Additionally, GoAL WaSH provided support to develop an MDG Roadmap and standards on small-scale wastewater treatment facilities. The second phase of the project addressed local level capacity gaps in water supply and sanitation service delivery, with a specific focus on operation and maintenance. This document gives a summary of the activities implemented during the project period (2010-2015) as well as the main achievements.
