The maximum daily design water demand Qd represents the highest daily water consumption that the urban water supply system may experience during its design lifespan. In calculating this value, it is necessary to include comprehensive domestic water use (or water use for residential purposes and public buildings), water for industrial production and for employees’ living needs, water used for watering roads and landscaping, water lost due to pipeline leaks, as well as unforeseen water usage amounts. The fire protection water demand is not included in the calculation of the maximum daily design water demand.
