Montenegro is facing a significant investment requirement exceeding €1 billion for its drinking-water and wastewater infrastructure over the next decade. The World Bank is preparing a new financing program aimed at enhancing municipal utility performance and reducing water losses.
The World Bank’s project preparation documents estimate that approximately €580 million will be needed for drinking-water investments, while €471.5 million is required for wastewater collection and treatment. This brings the total investment needs to over €1.05 billion.
This substantial figure underscores one of Montenegro’s most pressing infrastructure challenges, particularly as the rapid growth of tourism and real estate development places additional strain on municipal systems that already experience high water loss rates and limited wastewater treatment capabilities.
The World Bank is initiating the first phase of the Montenegro Water Services and Climate Resilience Project, with an estimated budget of around $58 million. This funding will include $35 million from the International Bank for Reconstruction and Development and $23 million from the OPEC Fund for International Development. The program aims to focus on infrastructure investments, improving utility performance, and enhancing climate resilience, with provisional approval expected by October 30, 2026.
A critical issue identified in project documentation is that approximately 68% of water entering municipal supply systems fails to generate revenue. This includes losses from physical leaks, inaccurate metering, unauthorized consumption, and other factors. Consequently, a significant portion of treated water is not converted into billable sales, which negatively impacts cash flow and the ability of municipal water companies to fund maintenance and new investments.
The energy costs associated with pumping, treating, and distributing water also pose challenges, as these processes continue even when water is ultimately lost from the network. Addressing leakage could reduce both water consumption and electricity expenses.
Montenegro’s wastewater infrastructure remains another area of concern, with less than half of wastewater currently treated. Coastal areas are under increasing pressure due to the influx of tourists, hotels, and seasonal population surges. This situation makes efficient water infrastructure vital for supporting tourism and real estate development.
The country has attracted substantial investments in coastal properties and tourism assets; however, municipal infrastructure development has not kept pace. This imbalance is particularly evident in regions where summer water demand approaches network capacity or where sewage systems struggle to accommodate additional development.
Investment in water networks can yield economic benefits that extend beyond direct financial returns. While new pipelines or treatment plants may not generate immediate commercial revenue comparable to hotels or airports, their absence can hinder further private sector development.
International financial institutions have increasingly recognized this need. Montenegro has previously utilized funds from the European Investment Bank, EU grants, and other programs to enhance water and wastewater systems across various municipalities including Ulcinj, Kolašin, Mojkovac, Rožaje, and Nikšić. The forthcoming World Bank initiative will introduce another significant financing avenue.
However, securing funding alone will not resolve the underlying issues. Municipal utility companies exhibit considerable variability in technical capacity, staffing levels, tariff collection efficiency, and overall financial performance. Some utilities struggle to meet operational costs without relying on municipal budgets or external transfers for investment funding.
This reliance undermines incentives for proactive maintenance efforts and allows high network losses to persist over time. Hence, the World Bank program’s focus on enhancing utility performance is crucial; reducing non-revenue water could yield substantial financial advantages before any major new infrastructure projects commence.
Improved billing practices or reduced leakage can effectively increase available supply without necessitating new sources—an especially important consideration along the coast where summer demand can significantly exceed winter usage.
The regional water supply system has already reported extremely high seasonal flows during peak tourist periods, with certain parts operating near capacity during the summer months of 2026. The bottleneck increasingly lies within local distribution networks rather than merely the availability of bulk water.
Climate change introduces further complexities; hotter summers and unpredictable rainfall patterns may heighten pressure on water resources while simultaneously increasing demand during peak tourist seasons. Additionally, intense rainfall events can overwhelm drainage systems.
The projected investment need exceeding €1 billion will likely require blended financing solutions. EU grants may support part of these costs as Montenegro progresses toward EU membership, while long-term debt could be sourced from institutions such as the EIB, EBRD, and World Bank. Municipalities and national budgets will also need to play a role in funding these initiatives.
Private sector involvement may be limited due to insufficient returns on many projects for traditional financing models. The immediate challenge will be effectively managing absorption; Montenegro is poised to undertake substantial investments across various sectors including roads, railways, airports, energy infrastructure, and environmental projects.
This simultaneous push creates pressures on engineering firms, public procurement processes, and government project management capabilities. Water-related projects often face unique challenges due to extensive local permitting requirements and construction through densely populated areas.
The identified investment gap of €1.05 billion thus represents not only a financial hurdle but also an execution challenge for Montenegro’s future economic growth potential. Sustainable development in tourism, housing, and commercial property relies heavily on the capability of municipal utilities to keep pace with rising demands.
The World Bank program will cover only a small portion of total requirements but may serve a more significant purpose by establishing a framework where improved utility performance aligns with new infrastructure development efforts.
While Montenegro possesses sufficient water resources to support growth ambitions, effective delivery to consumers and adequate treatment following usage remain critical issues that need addressing.
