# Losses in the water supply system of Greater Baku and measures on their elimination

### Summary

The population of Azerbaijan numbers more than 9.5 million people; half of the population is supplied with drinking water from the public water supply system. The water supply of Greater Baku (Baku city, Sumgait city and Apsheron) is carried out from five sources. In some communities water leakages reach 40–50%. Water losses in the distribution networks result in increases in operational expenses and reduction of the water network integrity. Water losses in the networks are mainly due to the following: commercial losses – illegal connections; physical losses – leakages; losses at calculations – water meter errors. The results of theoretical studies and practical measures on eliminating leakages in water distribution networks are presented. All the technical data is based on the actual information obtained from the relative water supply system maintenance departments of «Azersu» JSC.
