Groundwater

Water, which exists below the surface in the zone of saturation and can be extracted through wells or any other means or emerges as springs and base flows in streams and rivers. Groundwater flows and stored in geological formation capable of storing and transmitting ground water is known as aquifer which have sufficient yield to extract groundwater.

What Is Piezometer and RTDAS?

Piezometer is a bore well/tube well used only for measuring the water level/piezometric head of an aquifer and to take water sample periodically but not used for groundwater abstraction. Real Time Data Acquisition System (RTDAS) installed for automatic water level / water quality data of the monitoring system at desired interval and data transmit to defined portal.

What can Piezometer do?

  • It is a monitoring station of water level / static head and water quality of an aquifer
  • Piezometer network provides seasonal fluctuation of water level and water quality of the defined area.
  • Provide data for groundwater flow, estimation and availability for the defined area.

Benefits after piezometer construction under NHP

  • Sites for piezometer has been identified as per data gap of groundwater in coordination of Implementing agencies and Central Ground Water Board to enhance the data network for more precise estimation and predication of groundwater resources.

What can RTDAS do?

  • Measure water level and water quality parameter automatically at the station at desired interval
  • Transmit measured data to the defined portal at desired interval

Benefits after RTDAS installed on piezometers under NHP

  • Remote monitoring on of groundwater real time basis.
  • Provide high frequency data at desired interval for trend analysis for decision making
  • Minimal Human Intervention.
