One of the fundamental prerequisites for conducting any water resources study is the availability of reliable, accurate, and up-to-date statistics. Similarly, the most essential tool for implementing optimal water resources management is the accessibility of such data, which is achieved through nationwide census projects conducted every five years (though in practice, the interval often extends longer). These projects are carried out by Regional Water Companies utilizing consulting engineering firms. Therefore, water resources census projects – documenting both surface water and groundwater resources and their utilization – are regarded by industry experts as one of the foundational projects within the country’s water sector.
