“We have resolved the water supply problem, and now by order of the Dushanbe Administration we are developing the feasibility study for rehabilitation of the city’s sewerage system,” said Ahmadzoda. “We will submit the document for consideration to the Dushanbe Administration before the end of October this year.”
According to the Asian Development Bank (ADB)’s report, Proposed Grant Republic of Tajikistan: Dushanbe Water Supply and Sanitation Project, released in September 2018, Tajik capital has one sewerage network and wastewater treatment plant(WWTP) built in the 1970s, which has undergone upgrades with the replacement of pumping units and rehabilitation of sedimentation tanks. The sewerage system is separate, without storm water entry, and operates entirely under gravity conditions. However, it has numerous overflows to water bodies and agricultural land because of a design flaw in the south sewage collector. Dushanbe municipal waterworks (Dushanbevodokanal – DVK) estimates that 70% of the population is connected to the sewerage system and the remainder uses septic tanks. Wastewater undergoes only basic physical treatment through primary settlement. Although the WWTP has both physical and biological facilities, only the physical facilities are working.
