  2. Multilevel groundwater monitoring systems - Wikipedia

    en.wikipedia.org/wiki/Multilevel_groundwater...

    The Westbay MP system is a modular instrumentation system for multilevel groundwater monitoring acquired by Nova Metrix in 2015, the MP system consists of two parts: (1) the casing system and (2) portable probes and tools that provide a compatible data acquisition system. The Westbay casing system is designed to allow the monitoring of multiple ...

    en.wikipedia.org/wiki/Groundwater_recharge

    In 2007, on the recommendations of the International Water Management Institute, the Indian government allocated ₹ 1,800 crore (equivalent to ₹ 54 billion or US$640 million in 2023) to fund dug-well recharge projects (a dug-well is a wide, shallow well, often lined with concrete) in 100 districts within seven states where water stored in ...

  4. Well cluster - Wikipedia

    en.wikipedia.org/wiki/Well_cluster

    Well clusters are different from nested wells in that each monitoring well is constructed in a separate borehole, as opposed to multiple well casings in a single borehole which is the case with nested wells). A key advantage of a well cluster over a nested well is that there is less potential for vertical leakage and hydraulic short-circuiting ...

  5. Well - Wikipedia

    A dug well in a village in Faryab Province, Afghanistan The difference between a well and a cistern is in the source of the water: a cistern collects rainwater where a well draws from groundwater. A well is an excavation or structure created on the earth by digging, driving, or drilling to access liquid resources, usually water.

  6. Artesian well - Wikipedia

    en.wikipedia.org/wiki/Artesian_well

    An artesian well is a well that brings groundwater to the surface without pumping because it is under pressure within a body of rock or sediment known as an aquifer. [1] When trapped water in an aquifer is surrounded by layers of impermeable rock or clay, which apply positive pressure to the water, it is known as an artesian aquifer . [ 1 ]

  7. Watertable control - Wikipedia

    en.wikipedia.org/wiki/Watertable_control

    In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...

  8. Injection well - Wikipedia

    en.wikipedia.org/wiki/Injection_well

    An injection well is a device that places fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer. The fluid may be water , wastewater , brine (salt water), or water mixed with industrial chemical waste.

  9. WELL Building Standard - Wikipedia

    en.wikipedia.org/wiki/WELL_Building_Standard

    The WELL Silver, Gold, and Platinum level must achieve at least 1, 2, and 3 points per subject, but the WELL Bronze has no minimum points' rule. For WELL core, there are no minimum point. [3] The optimization point requirement from the WELL Bronze, Silver, Gold, and Platinum are ranging from 40, 50, 60, and 80 points. The rating system limits ...
