How deep do you reckon you can sink a well using 100 cm concrete rings?
We have 10 x 80 rings at the moment, some of which are damaged.
The idea is to take them all out, fit 100cm rings as deep as possible. We'll seal the top half and, in theory, only be getting water from the depths. There's a rice paddy next to us and we don't want the water from the paddy soaking into the well.
Seem like a plan?
