I am a member of Engineers Without Borders, a non-profit 
organization
focused on improving the lives of people in third world 
countries. I
will be traveling with a group of engineering students soon to
construct a water supply system for a village in Kenya. I would 
like
to get a list of contacts for PVC, PE pipe, and other hardware suppliers in the
country. I am particularly interested in getting contact 
information
for hardware stores near the Nairobi region. The only place 
I've been
able to find so far was a hardware store called New Ruaraka 
Hardwares.
Any help would be much appreciated.
