Decentralisation processes, undertaken for a series of activities formerly provided by the central government, led to major modifications in how the water sector was managed and operated. The only exceptions to this trend were Azerbaijan, Belarus and Turkmenistan, where water sector management has remained strongly centralised. In Azerbaijan, for example, the national company AZERSU JSC supplies water to 65% of the population, with 10% provided by small private operators and 25% by households themselves.
