As in the water supply sector, there are acute organizational problems in sewerage systems in rural areas, which make for a coverage rate of only 0.2 per cent. Of the 62 cities and district centres, only 29 have sewerage systems, and in villages there are virtually no sewerage systems. There are issues with the huge amount of surface water entering the sewerage system. However, the necessary financial resources for rehabilitation, expansion and construction of new systems in order to achieve the water and sanitation objectives and goals provided in the sectoral programmes are estimated to increase to more than US$2 billion.
