摘要：One of the major problems of waterworks is the excessive
failure of distribution systems and associated water leaks. Water losses
in water supply networks and systems are often a very high percentage
of water supplied into the network. Therefore, a comprehensive analysis
and assessment of water losses should be the basis for undertaking
modernisation efforts to reduce the costs associated with water production
and distribution. The article presents the analysis of water losses performed
on the basis of data provided by the Water Supply and Sewerage Company
in Radomsko. The data comprised the information on the water supply
infrastructure and quantitative water balance for the period of 2010–2015.
Based on the data, the following water loss indices were calculated: the
percentage water loss (PWS) or non revenue water (NRW) index, real loss
basic (RLB), non revenue water basic index (NRWB), unavoidable annual
real losses (UARL) and infrastructure leakage index (ILI). The obtained
results demonstrate that due to continuous actions in the recent years the
Water Supply and Sewerage Company in Radomsko has reduced the water
loss to the levels that correspond to the average water loss on national and
international levels.
