Rainy Season Drilling Considerations

After completing a well, pumping tests should be conducted to verify results. A large drawdown pumping test should maintain stable water levels for at least eight hours while measuring flow rates. Construction sites must ensure proper drainage, making rainy seasons less ideal for drilling operations. Excavation slopes should be determined based on soil properties, typically at a 1:1.5 ratio, with adequate distance between spoil slopes and excavation openings. For wells with shaft wall water inflow, proper inlet hole and filter layer arrangements are critical to prevent blockages during construction.

Water Well Drilling Best Practices

Conduct preliminary drilling to sample and create a structural diagram (histogram)
Design well pipes and filters based on geological structure with minimum 300mm drilling diameter
Ensure proper backfilling (1.8-2.0 m3) with siliceous sandy pebble filter material (20-40mm particle size)
Maintain well pipe verticality without tilting
Use 8mm thick polyethylene pipes with 18-20mm drilled holes (≥25% drilling rate)
Secure filter screens (25 mesh) with proper overlapping and fastening
