The amount of water which can be produced during 24 hours, considering the capabilities of production facilities at the end of year, without disturbing the equilibrium of water intakes and with preservation of technical conditions and requirements.

Production capacity of the whole water supply system in twenty-four hours is the amount of water which can be produced during 24 hours, considering the production capabilities of all facilities existing at the end of the year, ie. water intakes, water treatment stations and pumping stations. If water requires treatment and it is sent to the water supply system, then the production capability in 24 hours of the whole water supply system is equal to the production capability of the water intake in 24 hours.
