WHO and UNICEF established the Joint Monitoring Programme for Water Supply, Sanitation and Hygiene in 1990, and published regular global updates throughout the Millennium Development Goal period.
Smart meters collect and transmit real time water usage data from users, which can be used for billing, improve water efficiency and enhance customer experience.
Due to decreasing aquifer water level (280 million m3 per year), Veolia Water Technologies (Veolia) partnered with The Nature Conservancy (TNC) and local municipality to propose the establishment of a water fund to finance changes to local water-catchment and uses. As a result, Livelihoods Funds created a project to support vulnerable farmers in Aguascalientes to invest in drip irrigation equipment to enhance farm resilience. Changing to a drip irrigation system showed a 50% - 70% decrease in water consumption by farmers. If the 5,000 local family farmers in the water catchment area adopted this system through the new fund, this results in approximately 65% reduction of the annual aquifer deficit.
A water height and flood management system enables local authorities to predict flooding and avoid building infrastructure in high risk areas.
