A variety of water supply training manuals already exist, dealing with different topics and providing different levels of detail relevant to community managed water supplies. So why another manual? This Trainer’s Manual was commissioned by FAO and UNICEF, on behalf of the Water/NRM Technical Working Group, to respond to a stated need for a comprehensive manual covering financial, organisational, legal and technical aspects of community based water supply management which could be used by any state or non-state organisation to support capacity building activities. In addition, the Manual was intended to incorporate specific issues (e.g. performance monitoring, compliance to regulations and sector guidelines, rights based approaches, etc) that have been emphasised under the water sector reforms in Kenya.
