The fellowship allows rising leaders inside of utilities from across the country worked to develop access and affordability plans that ensure all people maintain access to water. CWSC also CWSC evaluated the effectiveness of federal water bill assistance at the state level, including data collection and reporting on shutoffs.

$238,386 spent60% of program spendingThe International Water Security Challenge (IWSC) program encompasses CWSC's work on setting legal benchmarks, assessing legal frameworks, and building legal and institutional frameworks for water security worldwide. This includes research on the impacts of law on the ability of water and wastewater systems to anticipate and manage the impacts of floods and droughts, realization of the human rights to water and sanitation and WASH standards in Africa, legal and service provision data collection, assessment of existing legal frameworks governing water resources and pollution control, and other means necessary to achieve water security.

The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $410k to $89k (−78%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2022 12% · 2024 17%. Grants only. Government contracts and fees sit inside program revenue.
100% of The Center for Water Security and Cooperation’s revenue is contributions — more reliant on donations than three-quarters of its peers (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 reported years ran a deficit.
