Methodological explanations
Water collected from intakes is the amount of water collected from an intake at the specific time, e.g. in a year, both raw water, requiring treatment (purification) and clean water not requiring purification.
The amount of water collected from intakes is calculated based on readings of water gauges installed in: wells, collective wells, pump stations or water drainage facilities delivering water for 1st degree of treatment. In case there are no water gauges, the amount of water collected from intakes is determined based on records from flow metres or other measuring devices, or based on output of water pumping devices and the time of their work in the reporting period.
Underground waters is the water appearing in the rocks of the earth. Depending on the depth of occurrence of groundwater aquifers and the distribution of structures and the surrounding works are distinguished: subsurface water, ground water, underground waters, deep waters.
Underground waters for the operation of the water supply network means water abstraction at intakes before being injected into the network.
