EFFECTIVE WAYS TO REDUCE DRINKING WATER LOSS - CASE STUDY FROM THE CZECH REPUBLIC
Abstract
The article deals with the effective reduction of drinking water loss in its distribution in the territory of the model municipality in the Czech Republic. Loss reduction is a long-term process that is one of the cornerstones of the strategy of each operator or owner of the water supply system. Losses of water in water network characterize not only the construction-technical condition of the distribution system in a given agglomeration, but also one of the business cards of the operator or owner of the distribution system. Finding and removing hidden leaks significantly helps to more efficiently use of drinking water supplied to the grid, where the operator or owner for the same amount of water supplied will receive a higher financial return on water and sewage. In these cases, it is, of course, necessary to deduct from the rate of profit the cost of detecting hidden water leakages and, in particular, the cost of repairing the identified defects. The fact that localized and subsequently repaired hidden faults on the water supply system, which behave latently from an external viewpoint, is another saving of funds for the operator from the point of view of accompanying phenomena, which characterize obvious disruptions (heated objects, damaged communications, violation of statics of objects, etc.). In these cases, the accompanying phenomena of apparent crashes from the point of view of issued funds are often up to ten times the cost needed to remove the hidden disorder.
