A clean water source is critical to the operation of a medical center

For its  30 years  the hospital has used a cistern  or bassin to catch
and store rain water.

Through  a  grant  from   the First Baptist Church of San Antonio,  
a 30,000 gallon  storage tower  has been  built  to  hold  clean   
water from La Source Boursiquot

This short video shows  the early construction of  the  tower which
was built entirely by hand
