Rehabilitation of existing sewerage systems and wastewater treatment facilities, and the creation of new systems and facilities in areas deprived of central sewerage systems, are inadequately financed. Within the framework of projects financed by international investors in 33 cities, regional centres and villages, KMK is working on the construction and rehabilitation of water and sewerage systems valued at more than US$168 million. Investment has increased substantially: in 2011, it amounted to 24.9 million somoni (US$5.4 million), in 2015, it was 2.1 times higher, at 52.4 million somoni (US$8.5 million).
