Abstract

Water intake in rural settlements adjoining large cities is variable and depends on many factors. In these places increasingly often a change in the character of water use from rural to the one typical of urban housing estates is observed. This is due to the expansion of housing, especially single-family housing, and migration of people from large cities. As a consequence, the standard of home furnishings improves and water is used not only for domestic purposes, but also for watering gardens and greenery, the filling and operation of swimming pools, etc. Considering the above, the authors present the results of own research relating to the analysis of water intake in villages adjacent to Wrocław.

Highlights

The size and distribution of consumer demand for water in the area of a given administrative unit is the basis for dimensioning its water supply and sewerage facilities
The global indices are determined on the basis of analytical-statistical studies of the water consumption so far, its multi-annual trends and the predicted trends stemming from the country’s long-term and targeted socio-economic development assumptions; - a method based on aggregate indices of water demand for different consumers in a settlement unit area per 1 inhabitant, which can be used in general plans and in technical-economic assumptions for water mains construction and extension for settlement units having a multifunctional character
The total daily water demand is the sum of the partial needs determined for the different groups of consumers on the basis of the unit aggregated indices and the assumptions concerning the long-term living conditions of the population; - a method of water demand balancing for different purposes in a settlement unit area, using detailed unit water demand indices

Summary

Introduction

The size and distribution of consumer demand for water in the area of a given administrative unit is the basis for dimensioning its water supply and sewerage facilities. The global indices are determined on the basis of analytical-statistical studies of the water consumption so far, its multi-annual trends and the predicted trends stemming from the country’s long-term and targeted socio-economic development assumptions; - a method based on aggregate indices of water demand for different consumers in a settlement unit area per 1 inhabitant, which can be used in general plans and in technical-economic assumptions for water mains construction and extension for settlement units having a multifunctional character. According the directives (1978, 1991), the values of Nd for single-family housing are assumed in the rage of 1.5-2.0
