It provides step-by-step instructions for digging an open well, including excavating soil to the desired depth, lowering concrete rings into the hole, and using aggregate to reinforce the well structure. The document calls for individuals and cities to take action to address issues like waste water and promotes building millions of wells while following water protection principles.

20. Digging an
open well
step by step
First the soil is
excavated to the
desired depth.
You may
encounter rock or
water
inflow/seepage.
The hole is
normally 6”-8”
wider than the
external dia of
the concrete
rings.
These wells can
cost anywhere
between 20k and
100k INR.

21. The soil is
excavated to
the required
depth
Concrete
rings are
lowered in
one by one
into the well
Aggregate or
jelly stones
line the gaps
between the
rings
This
reinforces
the well
structure
