Testing the performance of hydrants and carrying out their annual inspection are the activities aimed at fulfilling the
function of water supply system in the context of fire-fighting water supply to settlement units. The duty of checking
the condition of their work rests on the owners of firewater supply network and despite the fact that national
regulations contain information about requirements for water supply system as a source of water for fire
extinguishing, there are still some methodically unregulated issues, e.g. the procedure of carrying out hydrant tests.
Water consumed for own purposes of the waterworks, among other things during the hydrant tests, is in the water
balance so called unbilled authorized consumption. The article presents the results of the research on the hydrant
tests carried out in the water supply system in Olesnica and the analysis of the annual volume of water consumed
during these activities. The evaluation of efficiency and pressure of water flowing out of hydrants was done in the
light of reviewing national and foreign recommendations and requirements concerning their testing.
