Abstract

Water consumption in a settlement is an extremely variable size that changes constantly over time. Changes in water consumption occur on an annual, monthly, weekly, daily and hourly basis, and depend on many factors such as: climate, season, temperatures, hours of work, consumer habits, etc.

Extreme value of consumption, ie. the peak hour flow is defined as the product of the average daily consumption and the hourly non-uniformity coefficient. Non-uniformity coefficient is defined as the ratio of maximum flow to mean flow over a day, and given that actual flows fluctuate constantly over time, then it is easy to conclude that the non-uniformity coefficient is a variable that varies over time. In this case, the non-uniformity coefficient can be represented as a function C=f(t), which has local extremes at certain points, while at all other time intervals it has a smaller value.

With the known function of uneven consumption, using computer technology, it is possible to program different simulations of consumption and flow in the water supply system. In this way it is possible to optimize the system itself in terms of water consumption, dimensions and capacities of facilities in the system, as well as energy consumption for water transport.
