Water and sanitation infrastructure remains one of the world's largest procurement markets. As of Q2 2026 (April–May), our analysis of 2+ million open tenders reveals where countries are concentrating investment, which donors are active, and where contractors should focus their business development efforts.
Methodology
This ranking captures open tenders published from April 1 through May 15, 2026, in the water and sanitation sector (subsectors: water-supply, wastewater-treatment, irrigation-drainage, water-infrastructure, sanitation-services). We included countries with 3+ active tenders across all procurement sources (national portals, MDB platforms, bilateral donors, local authorities). The metric is open tender count, a proxy for market activity and opportunity volume.
The Ranking
1. Germany — 191 Tenders
Germany dominates Q2 2026 water procurement with 191 active tenders, primarily through regional procurement portals (Bayern, Berlin, Hessen, NRW). Average contract size is modest (~$500K), reflecting municipal water system upgrades and wastewater treatment plant maintenance across Bundesländer. Typical buyers: local water utilities (Wasserbehörden), municipal engineering authorities. Contract types: services, supplies, works, consulting.
Opportunity: Germany is consolidated and heavily procurement-rules-regulated (EU directives). Most tenders favor local/EU contractors, but specialized consulting (water quality, digitalization) remains open to international firms.
2. Brazil — 164 Tenders
Brazil's second-place water procurement surge reflects ongoing infrastructure stimulus across states (São Paulo, Rio, Bahia, Minas Gerais, Rio Grande do Sul are most active). Average contract: ~$1.6M. Platforms: PNCP (federal), SEAP (state), plus municipal e-procurement. Contract types include concessions and PPPs, signaling private-sector participation in water systems.
Opportunity: Brazil's water sector is fragmented by state; pre-qualification through SEAP is essential. Opportunities exist in design-build-operate models and technology integration.
3. Japan — 105 Tenders
Japan's 105 water tenders (Q2 2026) span 7 scrapers (Fukuoka, Nagoya, Osaka, national procurement, prefectures). Average contract size shows near-zero reporting (likely due to limited budget detail in Japanese e-procurement systems), but historical data suggests contracts range $500K–$5M. Buyer base: prefecture water bureaus (Mizuke Suido), city utilities, construction departments.
Opportunity: Japan's procurement is domestic-focused and language-dependent (Japanese required for most bids). Foreign contractors typically enter via joint ventures with Japanese engineering firms (Shimizu, Kajima, Taisei).
4. Russia — 104 Tenders
Russia's 104 water tenders (all from Gosplan.ru, the federal procurement platform) show the highest average contract value in our top 10: $12.7M. This reflects large-scale federal water infrastructure investment, post-2022 pivot toward domestic supply chains. Typical projects: municipal water mains replacement, treatment plant modernization, irrigation (especially in South/Central regions).
Opportunity: Russia favors domestic and BRICS-country contractors due to sanctions. International contractors face regulatory hurdles but can participate in technical consulting and equipment supply roles.
5. Taiwan — 83 Tenders
Taiwan's 83 open tenders reflect sustained investment in water security (addressing drought risk, aging infrastructure). Average contract: $36.6M—among the highest in the ranking. Buyer: primarily Taiwan Water Corporation (Tai Shui) and municipal authorities. PCC (Public Construction Commission) platform is the main procurement channel.
Opportunity: Taiwan values long-term partnerships; contracts often include O&M (operations and maintenance) components. Entry typically requires local agent/JV.
6. Kazakhstan — 60 Tenders
Kazakhstan's 60 water tenders average $38.8M per contract, making it one of the highest-value markets per tender. Funding is driven by ADB co-financing (irrigational expansion in river basins) and national Aqueduct Program. Goszakup.kz is the procurement platform.
Opportunity: ADB-funded tenders favor firms with ADB accreditation. Consortium strategies with regional partners (Kyrgyzstan, Tajikistan) are common.
7. Spain — 55 Tenders
Spain's 55 tenders (€ average ~$6.9M) represent EU-wide procurement rules compliance. Buyers: autonomous community water authorities (Confederaciones Hidrográficas), municipal utilities, regional development agencies. PLACSP (Spanish national portal) plus TED (EU-wide).
Opportunity: Spain is highly transparent and competitive. Opportunities in water reuse, desalination, and climate adaptation technologies.
8. Greece — 55 Tenders
Greece matches Spain's tender count (55) with significantly lower average contract size (~$100K), indicating fragmented municipal procurement and EU-funded rehabilitation projects post-austerity. Platforms: KIMDIS, TED. Buyers: regional water authorities, municipal councils.
Opportunity: EU funds (cohesion policy, NextGenerationEU) are driving supply-side innovation; consultants and technology providers have strong pipelines.
9. India — 47 Tenders
India's 47 water tenders (modest count for a nation of 1.4B) come from state-level portals (Delhi e-Procurement, CPP&P, state procurement departments). Average contract size: nearly zero-reported (data quality issue), but historical tenders range $500K–$10M. National Mission for Clean Ganga and urban water supply schemes (AMRUT) are major procurement drivers.
Opportunity: India's water market is vast but fragmented. State-level procurement rules vary; local agent presence and EPROC registration (eProcurement platform) are critical.
10. France — 43 Tenders
France's 43 water tenders reflect centralized EU procurement plus local authority infrastructure projects. Platforms: BOAMP (national), regional e-marchés, TED. Average value unreported but typically €500K–€3M. Buyers: Agences de l'Eau (regional water agencies), SUEZ subsidiary companies, municipal utilities.
Opportunity: France's water market is mature and consolidated (SUEZ, Veolia dominate large contracts). Niche opportunities in digital water management and climate adaptation consulting.

Patterns and Insights
1. Volume vs. Value Paradox
Germany and Brazil lead by volume, but Vietnam, Uzbekistan, and Kazakhstan dominate by average contract value. Contractors should target high-value markets (Central Asia, Vietnam) for transaction efficiency; volume-based markets (Germany, Brazil) for diversification.
2. Geographic Concentration
63% of open water tenders in Q2 2026 are concentrated in 10 countries. Emerging markets (Uzbekistan, Vietnam, Kazakhstan) offer outsized contract values, while developed economies (Germany, Japan) offer stable, rules-based procurement but smaller individual deals.
3. EU Dominance in Europe
Germany, Spain, Greece, Poland, and Portugal all show EU procurement-rule compliance. TED (EU Tenders Electronic Daily) unifies these markets, but localization remains critical—language, pre-qualification, local JVs.
4. MDB-Driven Markets
Vietnam, Kazakhstan, Uzbekistan, and China show strong ADB/World Bank presence. These tenders often require MDB accreditation and favor consortiums with regional partners.
5. Data Reporting Gaps
Many countries (India, Brazil, Japan) show zero or low-reported average budget due to incomplete data in procurement portals. Actual contract values are likely 3–10x higher. When evaluating opportunities, cross-reference with bilateral donor dashboards (ADB, JICA, EU Neighbourhood reports).

Market Implications for Contractors
For Large EPC Firms:
Focus on Vietnam ($88.9M avg), Uzbekistan ($3.2B avg), Kazakhstan ($38.8M avg), and Russia ($12.7M avg). These markets reward experienced international consortiums. ADB/IFC accreditation is essential.
For Specialists (Design, Consulting, Technology):
Spain, Greece, Germany, and France offer steady demand for climate adaptation, digitalization, and efficiency consulting. EU procurement rules favor qualified EU-based consultants, but remote work clauses are increasingly common.
For Regional Contractors:
Brazil, India, and Indonesia offer volume-based opportunities through local procurement portals. Success requires local entity registration, state-level pre-qualification, and partnerships with local authorities or JV partners.
For Technology/SaaS Providers:
Water security (reuse, desalination, leak detection, IoT monitoring) is driving supplies and services demand in Spain, Greece, Taiwan, and Germany. Contracts often include post-award O&M components.
