Our barangay need water for human consumption. We have a source from spring located in our Barangay. We want to capture all this spring water to meet our daily need. What shall we do. Remember that our source is mountain spring.

21 Boat answered that for another poster. It's called a "Spring Box"
Basically it's a hole with a box sunken in that hole of a low flowing creek from springs

It's a way to store a larger volume of water and its kept fresh by the intake and exit of the slow moving water.

Here are the plans on how to build one and how it works
