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 Bulgaria’s water sector are presented, which also shows average and best practices in the Danube region. The Bulgarian sector sustainability score is 66, which is just above Danube average sustainability of 64. The assessment shows that, on average, the country performs well in terms of access to piped water, staffing level, and nonrevenue water. The main deficiencies of Bulgaria’s water sector identified through the sector sustainability assessment are operating cost coverage, investment level, and customer satisfaction level.en-USCC BY 3.0 IGOSANITATIONWATER QUALITYTARIFFSFLUSH TOILETWATER SERVICESFLOWENVIRONMENTAL PROTECTIONASSET OWNERSHIPWATER ASSOCIATIONSANITATION SERVICEACCESS TO WATERQUANTITY OF WATERDAMSWATER COMPANYWATER SECTORINDUSTRYSANITATION COMPANIESOWNERSHIP OF WATERWATER UTILITYPROGRAMSWASTEWATER MANAGEMENTWATER SUPPLYWATER RESOURCECATCHMENTSRIVER BASINSDOMESTIC WATERREGULATORY AGENCYTREATMENT PLANTSSURFACE WATERUTILITY STAFFDRINKING WATER QUALITYPUBLIC WATER SUPPLYMUNICIPAL COMPANYSEWERAGE SERVICESWATER LOSSESWATER CONSUMPTIONWATER RESOURCESMUNICIPALITIESWATER STORAGETRANSFER OF ASSET OWNERSHIPWASTEWATER TREATMENTCONSUMER COMPLAINTSCOST RECOVERYWATER RESOURCE MANAGEMENTPERFORMANCE INDICATORSPOPULATION GROWTHBASINSWATER COMPANIESMUNICIPAL COUNCILSOPERATIONAL COSTSWATERWASTEWATER TREATMENT PLANTRAW WATERSUSTAINABLE WATERRAINFALLSEWERAGE SYSTEMSWASTEWATER INFRASTRUCTUREWATER DEVELOPMENTPOLLUTIONSERVICE PROVIDERPUBLIC WATERFORESTRYSERVICE PROVISIONWATER SCARCITYRUNOFFTOILETSWASTEWATER COLLECTIONWATER SUPPLY SYSTEMSWASTEWATERWATER STRATEGYMETERINGCLIMATE CHANGEWATER SERVICE PROVIDERSWASTEWATER SERVICESFRESHWATERPERFORMANCE DATAUTILITIESFLUSH TOILETSREGULATORY REQUIREMENTSWATER DEMANDCORROSIONSYSTEMSCENTRAL GOVERNMENTURBAN AREASWATER TARIFFSSANITATION SECTORNONREVENUE WATERRIVERSLOCAL STAKEHOLDERSSERVICE QUALITYPUBLIC WORKSMUNICIPAL COMPANIESSANITATION UTILITIESSANITATION STRATEGYWATER UTILITIESPIPED WATERWATER AVAILABILITYDRINKING WATER SUPPLYLAKESWATER COLLECTIONSANITATION SERVICESDRINKING WATERIRRIGATIONSTATISTICSGROUNDWATERHOUSEHOLDSWATER STATISTICSACCESS TO SERVICESREGIONAL DEVELOPMENTOPERATORSSANITATION INFRASTRUCTUREWATER MARKETNATIONAL UTILITYWATER SERVICEDOMESTIC WATER CONSUMPTIONSEAINDUSTRIAL WASTEWATERWATERSWATER SOURCEQUALITY OF SERVICENATIONAL UTILITIESSERVICE CONTINUITYSERVICE PROVIDERSReportWorld Bank10.1596/22134
