Already happening in Armenia

2015 to 2021USAID ASPIRED. More than 2,800 wells and springs mapped, real-time meters on the largest fish farms, data straight to the ministry. 135 dead wells found; closing one well at Sipanik saves 1.9 million m³ a year; fish-farm water reused on 40 ha at Hayanist.
2020 to 2025EU4Sevan. Hydrological and water-quality models of the lake, a vision to 2050, a decentralised wastewater plant at Noratus. Funded by the EU and Germany, run by GIZ and UNDP.
2022Water Code. River-basin management written into law on 7 July 2022.
2025ecoportal.am. Open environmental data: water use, losses, lake level, a Sevan dashboard.
2025 to 2031World Bank WISE. Sector institutions rebuilt, water user associations reformed, rural supply in six regions.
