The design capacity of a water supply can be derived from the peak factor. In this research, four different methods were used to determine the peak factor more precisely. Applying Method 1 could result in the design capacity being underestimated, by designing the lower part of the pipeline to apply the peak factor to the whole area. Applying Method 2 could overestimate it by 10–30% in the upper part of the pipeline by dividing the sum of the regional peak factors according to the ratio of peak day demand to the region. Applying Method 3 underestimates the design capacity in small areas, while it could overestimate it in large areas. Finally, Method 4 gives optimum results for the peak factor for estimating the design capacity.
