An Asian Development Bank-backed drinking water programme is upgrading treatment and distribution infrastructure across six districts in Karakalpakstan, an autonomous republic in northwestern Uzbekistan, according to a report published on 3 November 2026. The $145 million loan supports works that have expanded network coverage in Nukus district from 68 per cent to 90 per cent. Euronews.com The programme combines treatment upgrades, pipeline construction and local water-quality monitoring, while additional works remain under way. Euronews.com
KEY TAKEAWAYS
- The ADB is providing a $145 million loan for a drinking water project covering six districts in Karakalpakstan, with Uzbekistan contributing $27.3 million and total programme cost estimated at $172.3 million. Euronews.com
- More than 31,000 residents have benefited from works in Nukus district, where drinking water network coverage has risen from 68 per cent to 90 per cent. Euronews.com
- A new treatment plant in Mang‘it draws water from the Amu Darya River and currently supplies around 20 million litres a day, equivalent to 20,000 m³/day. Euronews.com
- The plant’s design capacity is 40,000 m³/day, based on projected population growth, business expansion and industrial development through 2040. Euronews.com
- A separate pipeline project involving approximately 355 kilometres is under way to raise drinking water coverage in Amudaryo district to 80 per cent. Euronews.com
Water network expansion reaches Karakalpakstan districts
Uzbekistan’s national drinking water network expanded from 63 per cent coverage in 2017 to 83 per cent, according to government figures released in July 2026, with around 39,000 kilometres built or reconstructed during that period. Euronews.com Despite that expansion, access remains uneven, particularly outside major urban centres. Euronews.com
In Karakalpakstan, ADB-supported works in Nukus district include upgrades to water distribution facilities, pipelines and local water-quality monitoring. Euronews.com The regional utility reported that more than 31,000 residents had benefited and network coverage had risen from 68 per cent to 90 per cent. Euronews.com A local testing laboratory has also reduced the need to transport samples to the regional capital for analysis. Euronews.com
Resident Muslima Erimbetova described the practical effect of household access: “We used to carry water with a shoulder pole and containers. We collected it from neighbours and public taps. Now, thank God, we have water.” Euronews.com
New Mang‘it plant serves water from the Amu Darya
A new treatment plant has been commissioned in Mang‘it and draws water from the Amu Darya River. Euronews.com It currently supplies around 20 million litres per day, while its 40,000 m³/day design capacity was calculated against projected population growth, business expansion and industrial development through 2040, according to Sohib Akramov, the ADB’s drinking water project coordinator in Uzbekistan. Euronews.com
Local officials reported that only around half of Amudaryo district’s population had network access before the latest improvements. Euronews.com A separate project involving approximately 355 kilometres of pipelines is under way, aiming to raise coverage to 80 per cent when completed. Euronews.com The ADB is also discussing a proposed $200 million project with the Uzbek government, including plans to reconstruct the Tuyamuyun treatment plant. Euronews.com
SPECIFICATION READ
The reported production scale is 20 million litres per day, which converts to 20,000 m³/day; the plant’s stated design capacity is 40,000 m³/day. Euronews.com The source does not report raw-water quality, finished-water quality, design flow per plant stage, treatment recovery, headloss or an equivalent population, so those procurement inputs cannot be calculated from the published information. Euronews.com
This event bears directly on raw-water abstraction, treatment-plant capacity, storage and distribution-network delivery. For a river-fed municipal water plant, the process train typically runs from screening and intake protection through coagulation and sedimentation or filtration, then disinfection before distribution; the supplied sources do not specify which treatment processes were installed at Mang‘it, so no particular biological or tertiary configuration can be assigned to that plant. Euronews.com Buyers can use the Water Purification product hub to scope the relevant treatment stages.
If your plant enquiry concerns a river-source drinking-water system with a flow near 20,000–40,000 m³/day, future population and industrial growth, and pressure to expand household connections without losing compliance headroom, this project means that production capacity, monitored water quality and distribution coverage must be assessed as one connected system rather than as isolated equipment packages.

FAQ
What is the cost of the Karakalpakstan drinking water programme?
The ADB is providing a $145 million loan covering six districts, while Uzbekistan is contributing $27.3 million, largely through tax and customs exemptions. The programme’s total estimated cost is $172.3 million. Euronews.com These figures cover the reported programme; the sources do not provide a breakdown of equipment, civil works, installation or commissioning costs, so they cannot establish an equipment-price range.
What capacity does the new Mang‘it treatment plant have?
The plant currently supplies around 20 million litres a day, equivalent to 20,000 m³/day, and has a design capacity of 40,000 m³/day. Euronews.com The capacity was calculated for projected population growth, business expansion and industrial development through 2040, but the sources do not report the stage-by-stage design flow. Euronews.com
What should a supplier be asked to prove when selected for this project?
The supplier should be asked to demonstrate how the proposed treatment train handles the Amu Darya source, the required 40,000 m³/day design basis, water-quality monitoring and future network demand. Euronews.com The published information does not include influent or effluent limits, reagent consumption, guaranteed output, construction duration or acceptance-test criteria, so those items would need to be specified in the tender enquiry rather than inferred from the project total.
How far will the pipeline project expand drinking water access?
The separate pipeline project covers approximately 355 kilometres and is intended to raise drinking water coverage in Amudaryo district to 80 per cent once completed. Euronews.com The sources do not report a commissioning date for those works. Euronews.com
