How to do Drilling in Courtyard
Consider whether the well depth is reasonable,We should first investigate whether there are cables, sewers and other facilities under the ground, and avoid unnecessary damage.. Convenience, health and other issues should be considered.
After drilling the well, find some charcoal and throw it into the well with a bag and press it at the bottom of the well to absorb foreign toxins. After having water, you can put a few small fish down, which is a good way to test the safety of water quality.
