Sustainable drinking water supply of Baku and its suburbs is regulated mainly by means of reservoirs and distribution networks located in various reliefs. Water brought from the sources to the capital is transmitted via the main lines to the reservoirs and then distributed to the network. The existing reservoirs, along with the provision of uninterrupted water supply to the population, also allow the accumulation of certain reserves.

According to the requirements, the reservoirs are washed and disinfected periodically and the water quality is monitored daily by the Central Laboratory. At the same time specialists of sanitary-epidemiological institutions regularly inspect the stocks.
