La experiencia del proyecto alimentacion de agua para pueblos jovenes (APPJ) : servicios de agua en zonas periurbanas de Lima Metropolitana 全文
de Walque, Damien | Verwimp, Philip
This document is the first systematic discussion of the most important lessons of the APPJ Project of the European Union, which was implemented between the years 1993 and 2001. The project was prepared to respond to the emergency health situation of the cholera epidemic of 1991. The proposed project was to comment on building autonomous systems of drinking water in peri-urban areas not served by the SEDAPAL drinking water network. Lessons learned include: 1) It is not enough to build drinking water systems; 2) It is essential to ensure the existence of units that manage the system efficiently. 3) It is important to operate a monitoring program of the autonomous systems in Lima. This document has been divided into five chapters and three annexes. The first chapter presents the background of the project, the features of the proposal and phases their execution. The second deals with processes that led to major improvements in the construction of the autonomous systems of drinking water. The third chapter discusses the various aspects and factors influencing the sustainability of water systems. The fourth chapter discusses the role of institutional actors involved directly or indirectly in the sustainability of building water systems. Finally, the fifth chapter presents conclusions and lessons. The document ends with three annexes: the first is information on costs and volume of sales of systems visited; the second is a summary of the information status of systems visited, and the third is a list of NGOs who have participated in the implementation of the project.

Fernandez, Diego
This study presents the evolution, present situation, and perspectives of the water supply and sanitation sector in Colombia. The sector is totally decentralized, given local administrators of the 1100 existing municipalities the responsibility of servicing their urban and rural populations. The government participates as a regulator and defies the sector policies. The development of the water sector in Colombia has been considerable in the last 10 years, mostly due to the new institutional and regulatory framework as defined in the Law 142 of 1994 (Ley de Servicios Publicos Domiciliares) and subsequent government decrees and resolutions by the Comision Reguladora del Agua (CRA). As for new tariffs and future of the sector, the CRA has not been able to define the new regulatory framework (nuevo marco regulatorio) which would bring a reduction in tariffs. Such reduction is unnecessary in a country where there is no regulation for the treatment of waste water disposal. This is a background document to the main report : Colombia - Recent economic developments in infrastructure (REDI) - balancing social and productive needs for infrastructure.
