Ukraine and Moldova agreed on 30 September 2026 to keep exchanging water-monitoring data and to coordinate their response to the hydrological situation in the Dniester River basin, after a meeting of bilateral working groups in Chișinău Межа. Новини України.. The talks were framed by low water levels across the basin and a March 2026 contamination episode that has put the shared river back on the agenda of utilities and procurement teams in both countries Межа. Новини України..
“The low-water conditions we are seeing this year are another reminder of how important it is to develop shared approaches to water resource management, strengthen monitoring, and prepare solutions in advance for different hydrological scenarios,” Iryna Ovcharenko, Deputy Minister of Economy and Environment of Ukraine, said after the meeting Межа.

Specification read
The reported Davydiv upgrade is a small municipal plant at 500 m³ per day, which is 0.5 MLD and serves a community in the order of 3,000–5,000 people (general industry range, not from the sources). At that scale, the typical treatment train is coarse and fine screening, grit removal, primary clarification, biological treatment such as a packaged SBR or MBBR for carbon and ammonia removal, tertiary filtration and UV or chlorination disinfection, with sludge handling thickened and dewatered on site. The Davydiv project, as described, is a capacity-and-compliance upgrade rather than a new greenfield build, so the procurement focus sits on the biological stage retrofit, the disinfection package and the control/SCADA interface to the new automated monitoring that the ReHydrUA initiative is designed to feed. The Zalishchyky project adds sewerage network reconstruction to the WWTP work, so buyers there are also watching pipe-laying lots and pumping-station packages alongside the process equipment. If your plant looks like this — flow in the 0.2–1 MLD range, municipal/domestic load with periodic industrial discharge, discharge to a transboundary river under tightening ecological-status rules — the signal is that Ukrainian utilities are now budgeting process upgrades and sewerage renewal together, and that any supplier quoting only one of the two will be screened out. For background on what a 0.5 MLD class municipal build costs in today’s market, see our Municipal sector page and the Water Treatment Plant Construction Cost per MGD (2026 Data) reference. Process-equipment vendors weighing the Ukrainian tender calendar should also track the Chemical side, since coagulant and polymer dosing for the tertiary stage tends to be specified in the same tender packages as the biological retrofit.
FAQ
What is the headline capacity figure from the Davydiv upgrade?
500 m³ per day, equivalent to 0.5 MLD, at a reported cost of UAH 26 million Межа. Новини України.. Population equivalent depends on local per-capita load (general industry range, not from the sources).
When is the Zalishchyky WWTP and sewerage project due to finish?
November 2026, with the project more than 70% funded at around UAH 70 million Межа. Новини України.. Equipment suppliers should plan delivery against the remaining financing and construction window.
What is the ReHydrUA sensor programme and where is it in procurement?
ReHydrUA involves installing 60 automated water-level sensors across the basin and is currently at the proposal-selection stage before further funding Межа. Новини України.. Expect a separate instrumentation tender once selection closes.
How big is the overall Dniester basin work programme?
From 2025 through the first half of 2026, Ukraine reported two measures completed, 19 in progress and 105 programmed, with funding of around UAH 305 million Межа. Новини України.. That is the envelope planners are working against, not a single contract (general industry range, not from the sources).
