How this list is built
Counted are World Bank-financed consulting services contracts in water and sanitation projects signed between 1 November 2024 and 31 October 2026 in any borrowing country, where the financing project is classified under water and sanitation as its only sector, valued at each company's recorded share of the contract in US dollars; contracts with individual consultants, government bodies, universities and research institutes, hospitals, non-profit groups and United Nations or other international agencies are left out. Joint venture contracts are split between the partners as recorded (usually in equal shares), so no contract value is counted twice and each partner is credited with one contract, while contracts recorded only under a consortium name are left out. Subsidiaries and spelling variants are rolled up to one company where the parent group is clear and public (for example China Road and Bridge into China Communications Construction), and ties share a rank.
Every position is set by the data alone, by the same rules for every company. Spotted something to update? Write to info@stratummarketresearch.com with the list and the line, and we correct it within two working days.
