Mingachevir reservoir was selected as a source for providing Mingachevir city, as well as surrounding villages with drinking water and a modern water treatment facility was commissioned near it. At the initial stage, a 720-meter-long main carrier belt from the pipes with diameter of 800 millimeter was constructed to transfer natural water to the treatment facility. The location of the cleaning device has been selected so that the water in the lake will be transmitted in a water-intensive mode even if the water level in the lake is low. In order to provide consumers with high-quality drinking water, a modern-type sand filter treatment facility with capacity of 55,000 cubic meters per day or 636 liters per second was constructed. The water purification is carried out without the use of any chemical reagents here and its quality indicators fully meet the standards of the World Health Organization. The processing is fully automated here and operated from a single center with the SCADA system. It is automatically controlled with the help of sensors to the input and output parameters of the water in the fully operational mode. A pump station with a capacity of 2100 cubic meters per hour has been installed to deliver fresh water to the warehouse located at a height of relief. A water reservoir with a capacity of 85,000 meters above sea level was built to optimize management and distribution in the self-propelled regime. At present, the treated water is transmitted to the warehouse and transferred to the urban network in a self-contained mode. In the future it is planned to supply drinking water to Yevlakh city and 7 villages with population of 8500 people from this plant. To this end, the construction of a new 35 km long transmission main and two reservoirs with a capacity of 5,000 cubic meters has been planned from Mingachevir reservoir to Yevlakh. The 2.8-kilometer section of the transmission main, which runs via the Kura river has already been built and is ready to operate.
