Just to make two points:

A surface spring does not mean that a hand-dug well will be successful at that location (or even slightly up-stream). Springs can occur in geological conditions unfavourable to hand-dug wells.

Even if the formation were favourable, you might find it very difficult to dig a 20m well there, even with caissoned well rings and mechanical dewatering.

One issue is whether the spring is used just for people or also for watering animals. This should be allowed for in the design, or the needs of the animals will take precedence.
