Please fill in this form and we will contact you with more information and a class date. You will find the class to be very informative. It is a small group, hands-on and lasts about 3 hours. There is a cost of $99 just for the materials - you get systems for water filtration & disinfection, a hand-wash system, buckets with labels, and an easy-to-follow handout. The know-how and training is provided by knowledgeable volunteers, free of charge.
