For fire extinguishing. According to Daily average, maximal daily, hour and second average water consumptions, considering seasonal of non-uniformity water consumption on each priority district centers are defined. 4. Sources of water supply and their estimation The main source of water supply of Alat and Karakul is surface water of the canal. Current capacity of the source and impact of the project is presented below in Table №1 Table №1 № Description of Source Capacity of canal m3/s Selection for today t.m3/day Selection of project, t.m3/day 1 Amu-Bukhara canal 100 3,75 49,816 The design capacity of "Dvoinik" intake is 49,816 thousand m3/day, taking into account own needs (water consumption which takes off a sludge from sediment pool, and water consumption which washes filters, etc.). Coverage of demand with sources of water supply for Alat and Karakul cities is shown in table #2: Table №2 № Description Required water consumption t.m3/day 2020.
