Monitoring Well Screen


Johnson screen product manufacture.

Monitoring well refers to the special well completed by drilling to monitor the change of groundwater level, water temperature and water quality.
The construction method is similar to that of conventional water wells. After completion of the well, monitoring instruments are placed in the well, and water samples are regularly taken for analysis and test.
Monitoring wells are arranged in the pollution source concentration area, and horizontal wells have been used to measure and control groundwater pollution in a large area in foreign countries.

Our company provides various specifications of monitoring well screen (Prepacked Screen) design and customized services.

  • Measure the depth of the monitoring well every two years. When the siltation in the monitoring well fails to reach the monitoring well screen filter pipe or the depth of water in the well is less than 1 m, the siltation shall be removed or the well shall be changed in time.
  • Water permeability sensitivity test shall be conducted for monitoring wells every 5 years. When the water volume of 1m well pipe in the water injection section is injected into the well, and the water level recovery time is more than 12min, the well shall be washed.
  • In case of displacement or damage of wellhead fixed signs and orifice protection caps, they must be repaired in time.
