As Ukraine enters the fourth year of full-scale conflict, the war’s long shadows stretch far beyond the battlefield, reaching into the fundamental systems that sustain civilian life. One such domain — often invisible until it fails — is water infrastructure. At the Lviv Ecoforum in late 2025, government and international representatives underscored a stark reality: Ukraine’s water systems are both a battleground casualty and a cornerstone of future national resilience. The task ahead is not simply restoring war-damaged pipes and pumps, but redefining an infrastructure capable of withstanding climate, economic and security pressures in the decades to come.
A system under strain
Before Russia’s invasion in February 2022, Ukraine’s water and sanitation system already bore the marks of underinvestment: ageing networks, inefficient treatment facilities and uneven access between urban and rural areas. The war has profoundly exacerbated these structural weaknesses. According to UNICEF’s 2025 assessment, more than 39,700 kilometres of water networks have been damaged, with total water sector losses reaching roughly USD 4.6 billion, and reconstruction needs for the decade projected at USD 11.3 billion. The destruction of the Kakhovka Dam alone left about a million people without water access and inflicted hundreds of millions in recovery costs.
Even beyond physical damage, the quality of water supply has deteriorated sharply: one-third of drinking water samples fail to meet national standards — a stark contrast with EU member states where non-compliance is typically below 1 per cent. This has direct implications for public health, particularly among children, as UNICEF’s reports highlight ongoing risks from poor sanitation and unsafe drinking water.

Reconstruction as Renewal
At the Ecoforum, Serhii Sukhomlyn, Head of Ukraine’s Agency for Restoration, framed water infrastructure not as a mere repair job but as an opportunity for systemic transformation. With only 32 per cent of wastewater currently treated — compared with 80 per cent across Europe — Ukraine confronts a looming crisis that could undermine economic recovery and environmental health if left unaddressed. Water loss on distribution networks sits near 40 per cent, representing both inefficiency and vulnerability.
The strategic response, articulated by Sukhomlyn and Deputy Minister Kostiantyn Kovalchuk, combines energy-efficient network upgrades, renewable power integration, and modern treatment plant construction. Solar-powered installations at water intakes, supported by UNICEF, show one practical approach: ensuring continuity of supply even amid power outages — a common consequence of both military action and energy shortages.
International momentum and financial architecture
Reconstruction of water infrastructure in Ukraine is not an isolated national effort but a focal point of international partnership. The World Health Organization (WHO) and UNICEF have been coordinating with Ukrainian authorities to establish water safety planning frameworks aligned with the EU Drinking Water Directive — a step that supports Ukraine’s broader EU accession agenda while anchoring domestic reforms in international norms.
Financial instruments are emerging to underwrite these ambitions. The European Investment Bank (EIB) is financing a €70 million project to restore potable water systems in Mykolaiv, one of the cities most acutely affected by infrastructure destruction. Similar EU-backed initiatives in Kryvyi Rih aim to rehabilitate pipeline networks and treatment facilities, benefitting hundreds of thousands of residents. These investments signal confidence in Ukraine’s reconstruction trajectory and underscore water infrastructure’s centrality to societal recovery.
Strategic importance: beyond pipes and pumps
Rebuilding water infrastructure carries multiple layers of strategic significance:
- Public health security: Adequate water and sanitation are prerequisites for disease prevention, stable communities, and reduced burden on an already strained healthcare system.
- Economic revival: Reliable water systems underpin industry, agriculture and urban livability. Without stable supply and treatment systems, recovery of broader economic activity is constrained.
- Climate resilience: Ukraine faces intensifying climate stresses, including drought risk that experts warn could force water imports by 2050 if adaptive infrastructure is not established. A forward-looking approach integrates water management with climate adaptation, decarbonisation and energy-efficient operations.
- Social stability and equity: Disparities in access — with only about 26 per cent of rural communities having centralized water supply — risk entrenching inequality and population decline in secondary regions unless addressed through inclusive planning.
Obstacles on the path forward
Despite clear imperatives, obstacles remain formidable. The vast scale of damage — with an estimated nearly 90 per cent of facilities operating beyond their intended lifespan — complicates rehabilitation efforts. Water utilities, already weakened financially and overwhelmed by rising energy costs, operate with tariffs set below cost-recovery levels, undermining sustainability without targeted fiscal support.
Furthermore, the war continues to buffet key regions, making reconstruction planning inherently uncertain. In this context, modular, decentralised solutions (such as prefabricated sewage treatment systems highlighted at the Ecoforum) may offer tactical advantages, allowing communities to rebuild incrementally while maintaining service continuity.
Water security as national resilience
Reconstructing Ukraine’s water infrastructure is an investment in national resilience — economically, socially and environmentally. Beyond restoring what has been lost lies the opportunity to modernize systems, align with European standards, and embed climate-adaptive practices into the backbone of public utilities. International partnerships, financial frameworks and innovative technologies are all converging on this nexus, reflecting recognition that water security is foundational to Ukraine’s recovery and future prosperity.
With strategic focus, sustained financing and integrated planning, Ukraine’s water infrastructure reconstruction can become a model of post-conflict renewal — ensuring that the water flowing through its pipes is not only safe to drink, but symbolic of a nation rebuilding with foresight and resilience.
