Generally, urban water supply and sanitation in Tajikistan is in bad condition due to the lack of maintenance since the break-up of the Soviet Union. EBRD and SECO started cooperation on water projects in Tajikistan in 2004 with the Khujand Water Supply Project Phase I. The City of Khujand (population 167’000) is the second largest city of Tajikistan. The project phase I was completed in 2008 and yielded promising results. Therefore, the EBRD and the SECO approved a second phase in 2009. Thanks to these two phases, the conditions of the water supply systems have improved substantially, while the wastewater sector is still in a very bad state therefore EBRD started the programme Khujand water supply improvement programme phase III which includes 3 Lot’s and the contract for LOT-1 & LOT-2 is awarded to our company FELA Planungs AG from Switzerland for Rehabilitation of existing Wastewater Treatment plant (WWTP) LOT-1 and Rehabilitation of Pond System and Auxiliary Structures LOT-2.

The existing WWTP was built in the 1970’s. The mechanical and biological units are out of operation for more than 10 years. All electro-mechanical equipment has either been removed or is completely dilapidated and non-functional.
Expected results after implementation of the project will be a fully functioning Waste Water Treatment Plant and the impact of the project will improve living conditions and economic opportunities for the population of the city of Khujand.
