Menor costo con mayor beneficio: servicios de agua y alcantarillado para familias de bajos ingresos
Fedderke, Johannes W. | Bogetic; Zeljko
This field note reports lessons from a recently concluded pilot project in the city of El Alto, Bolivia. The project aimed to find innovative ways of reducing the cost of providing water and sewerage connections to poor households, while at the same time ensuring that they reap the full benefits of these services. The results are encouraging. First, costs of both water and sewerage connections were reduced by around 40%. This was achieved by adopting a condominal network design (that connects groups of houses to the main supply rather than each individual home) and using volunteers from the community to carry out construction. Second, hygiene education resulted in an increase in the number of people installing bathrooms. The percentage of households who put in bathrooms (at75 percent) was twice that among people who did not receive training (35 percent). Water consumption also rose among these households by 30 percent, compared to what they used prior to education. Micro credits had a small effect in encouraging people to install bathrooms but did not succeed in reaching the poorest households and were thus eventually discontinued.
