The tariff collection rate fell to 86%, and user charge revenues covered just 40% of water production costs. Tariffs were increased only once in April 2008. The tariff for domestic customers was increased from UAH 2.94 to UAH 4.66 per m3 (respectively 0,38 EUR/m3 and 0,60 EUR/m3) whilst the tariff for public organisations was increased to UAH 5.93 per m and for other customers to UAH 8.61 per m3. At the same time, the lease agreement did not contain requirements to invest into the development of utility infrastructure facilities. For instance, in the Russian Federation some PPPs were cancelled after municipal elections. Possible solutions entail consolidating utilities at regional level or pooling services to invite one operator in a larger area.
