To evaluate and reflect the sustainability of services in the region, an overall sector sustainability assessment was done, taking into account four main dimensions: access to services, quality of services, efficiency of services, and financing of services. Each of these dimensions is measured through three simple and objective indicators. For each indicator, best practice values are established by looking at the best performers in the region, and countries closest to those best performers are deemed to have a more mature sector. A more complete description of the methodology to assess the sector sustainability is included in the Annex of the State of the Sector Regional Report from the Danube Water Program. The outcomes of this assessment for the Moldova water sector are presented, which also shows average and best practices in the Danube region. The Moldova sector sustainability score is 50, which is below the Danube average of 64, and is among the lowest scores in the region. The assessment shows that, on average, the country performs well in terms of collection ratio, nonrevenue water, and continuity of service. The main deficiencies of the Moldova water sector identified through the sector sustainability assessment are access to piped water and flush toilets, affordability, and investment level.
