Local crews drill wells which provide long-term supplies of safe drinking water for 200 to 500 people. (See the example of the Liberian crew)
The centerpieces of this program are the lightweight LS-100 and LS200 mud-rotary drill rigs. They are affordable, simple to operate and portable: they can be transported in the back of a small truck to remote locations.
Using drill mud, the LS-100 can drill a 6-inch bore hole more than 100 feet underground.

Vault toilets and pour-flush toilets are built using simple, readily available tools including:
