ANALYSIS OF THE WATER USE IN DIFFERENT TYPES OF BUILDINGS

The analysis of the water use of the different consumers is an important issue for the proper design, performance and management not only for the water supply and sewerage systems in the buildings, but also for the urban water infrastructure as a whole. Water use changes with time due to many climatic, socio-economic, cultural and technical factors and is tightly connected with the development of the society and technologies. When the change becomes substantial, there is a need of upgrading and verification of the design parameters and methods, but also the construction practices and maintenance requirements as well as the corresponding regulations, so that they become adequate with current and future development. Analysis of the different methods characterizing the water use in the buildings on quantative basis as well as the determination of its seasonal, daily, hourly or shorter period of time variation is made. The advantages and disadvantages of water demand mathematical models are discussed and on that basis of that, a statistical method for estimation of the parameters of hybrid stochastic-regression water demand model is recommended to be used. The approach gives contemporary theoretical basis of water demand on different spatial and temporal scales and can be used for analysis of water consumption not only in the different types of buildings but also in the settlements.
