Rehabilitation of Kakanj Water Supply

Country: Bosnia-Herzegovina

The Kakanj Utility was not any more in a position to provide a 24-hour supply. The system was affected from frequent break-downs, instable supply and poor water quality. 

A rehabilitation program was agreed with KfW, comprising the complete rehabilitation of the system. This includes first an inventory and assessment of the complete system, the identification of deficiencies and shortcomings and as a result of this, the formulation of the rehabilitation measures. The original concept foresaw the rehabilitation and expansion of a groundwater source. An extensive well test was carried out, showing that this source was insufficient in capacity and could not sustain the required water quality at large quantities. Consequently, the rehabilitation of an old and deteriorated surface water source became necessary.

The rehabilitation works finally included the construction of a new surface water intake, sand trap, complete conventional water treatment plant for a capacity of 130 l/s, including chemical operation building, the rehabilitation of a groundwater source, rehabilitation of 180km transmission and distribution lines, replacing house connections, metering of all connections, a new SCADA system, optimisation of the treatment plant process and training of staff. The project further includes institutional support to the water utility, preparation of a tariff model and presentation of the results in front of the Municipal Council.
