World Rotaract Week Water Pasteurization Indicators Project
World Rotaract Week 2011 - March 7th -13th
Every year, World Rotaract Week honors the chartering of the first Rotaract club in 1968. World Rotaract Week is a time for
Rotaractors and Rotarians around the world to come together to celebrate the success and importance of the Rotaract program.
This event is also an excellent opportunity to inform members of your community about the amazing work that Rotaract clubs
do, and give them an opportunity to get involved.
Sunday March 13th from 10:00 am - 4:00 pm
Hosted by West Los Angeles Rotaractor Catalina Falla

We need your help making WAPI’s to send to Rwanda
A Water Pasteurization Indicator (WAPI) is a simple thermometer that indicates when water has reached pasteurization
temperature and is safe to drink. It was invented by Fred Barrett and Dale Andreatta.
Pasteurization destroys all microorganisms that cause diseases from drinking contaminated water and milk. A small
polycarbonate tube contains a wax that melts when water or milk is heated enough to be pasteurized (65˚C/149˚F). This saves
much fuel by eliminating the need to boil water or milk to ensure that the pasteurization temperature has been reached.
Since water pasteurizes at temperatures well below the boiling point of water, WAPIs save time when solar pasteurizing, and
save fuel when using traditional fuels.
