A substantial share of w'ater consumers experience difficulties paying for water supply services and sewage disposal. Moreover, 60% of the water pipes and half of the sewage collectors are in a dilapidated state, water quality indicators often do not meet human health and safety standards, and large quantities of water are lost to leakage in the networks (around 40% of total supply). In Tbilisi and Rustavi, the WSS systems have been privatised and are now privately owned by the Georgian Water & Power company.
