This document will address RAINs guidelines towards water quality and will give practical
guidelines to improve and maintain an acceptable water quality of harvested rainwater for
drinking purpose. It will describe criteria for water quality of harvested rainwater, placed within
the socio-economic and geographical context of RAINs target countries. The most practical
approach of improving and maintaining the quality of harvested rainwater in rural water supply
schemes is not to impose a set of unachievable targets, but to insist on adequate measures of
quality protection which significantly improve the quality of water, compared with traditional
sources (Morgan, 1990).
