"Faithfully harvesting the rain", is a case study written by Shree Padre in September 2005, about the RWH work of an old church in Dakshina Kannada district, where despite living in one of the rainiest places in the nation, monks put up a roof water harvester many decades ago, and maintain it to this day. This goes to show that rainwater harvesting isn't just for drought-prone regions, nor is it an entirely recent development.
