Water Quality and Well Depth
In general, when it comes to water quality and well depth, there's one golden rule: the deeper the well, the better the water quality. As you go deeper down, there's a higher chance that the water you encounter will be rich in minerals.
Dewatering Well Construction Process
Well point measurement and positioning → hole digging and casing embedding → drilling rig in place → drilling → hoisting well pipe → back-filling filter material (coarse sand or gravel) between well pipe and hole wall → hole washing → drainage pump in well pipe and installation of pumping control circuit → trial pumping → normal operation of well point → dewatering completion, pipe pulling → well sealing.
