In November 2005, Aguaconsult fielded a consultant to support the members of the Agua para Todos partnership to analyse and document how this partnership had been successfully working in providing decentralised water supply systems in urban barrios. The main partners included a local private sector pipe manufacturer, the Cochabamba municipal council, the public sector utility provider, local NGOs as implementers and a local micro-finance provider. This short paper was written by Aguaconsult following a visit to the region and examines both the success factors that have enabled the positive growth of the partnership model as well as potential hurdles for scaling-up. The paper considers a number of possible scenarios relating to scaling-up and replication including scaling-up of the partnership within its existing context of specific districts of Cochabamba and potentially to work in other parts of the concessionary area; replication of the model in other peri-urban contexts within Bolivia; and the possible replication of the model in other countries in the Latin American region. The output of the Aguaconsult technical support also resulted in the development a detailed funding proposal to increase the size of the credit portfolio, as well as to raise grant funding to cover associated software and capacity-building activities.
