Abstract

Distance and time of water effluence on soil surface after failure of buried water pipe. Laboratory investigations and statistical analysis

Highlights

The use of water supply pipes all over the world has always been accompanied by breakages and leakages
Obtained laboratory test results allowed to determine anticipated values of the distance between the place of the water effluence implied by Table 3, but to 28.18 cm, constituting the result of number on the soil surface and pipe leak after the breakage of the water sup- 10 raised to the power of the logarithm arithmetic mean of measured ply pipe, based on statistical estimations calculated with Statistica 10 distances
Failures and leakages are inextricably linked to the use of water supply systems and, apart from economic loss, they generate a real risk of dangerous suffosion phenomena in the soil

Summary

Introduction

The use of water supply pipes all over the world has always been accompanied by breakages and leakages. What can reduce a number of damages is skilful management of a water supply system and proper maintenance It is, impossible to entirely eliminate such incidents as, most often, they occur randomly [5, 7, 24]. The threat emerges as a result of the particles being washed out from the soil skeleton during the breakage of an underground pipe which can lead to the formation of empty spaces beneath the ground surface and contribute to the creation of depression or holes in the Earth’s surface (suffosion processes) [1, 4, 9] Such incidents took place worldwide and produced detrimental social and economical effects [22]. Occurrence of internally unstable soils, especially in the range of the loess plateau [2] as well as a high failure intensity rate of water supply systems, compared to other countries [15, 16, 18, 19], are factors which increase the risk of the emergence of such a problem in Poland
