Big Island Rainwater Catchment Tradeshow ‘07

The Rainwater Catchment Tradeshow ’07 was held on August 16, 2007 at Keaau High School on the Big Island.  Rotary Clubs of East Hawaii prepared and served a buffet-style dinner.  Volunteers and members of the Hawaii Rainwater Catchment Systems (HRCS) Association decorated the room and greeted guests.  Local vendors, servicers, and suppliers had display booths and answered questions.  In addition, attendees could ask questions from both a national panel and local experts.  The event cost $10, including dinner.  The tradeshow was planned by CTAHR Education Specialist Patricia Macomber, MPH, and was attended by 205 people.

Keaau High School on the Big Island was a convenient and large location for the tradeshow because it is centrally located on the island where large numbers of residents are on catchment.
