A response to the challenge
of universal sanitation
available for download: developed in partnership between Prof. Jose Carlos Melo and The World Bank (December 2008)

2. DRIVING REASONS BEHIND THE MODEL
Developed over the past 30 years to address unmet demand, and motivated by:
Sanitation as a basic need
Large scope of unmet demand
2 billion people worldwide without access to sanitation services
100 million in Brasil
Lack of an appropriate model for cities to address large unmet demand in a flexible manner, with reduced investment ability, and various urban contexts

3. The condominial model is not restricted to urbanized or planned areas
It aims at starting from different existing realities of urban occupation: suburban or favelas, neighborhoods without access to services

4. What does “Condominial” mean?
An agglomeration of houses or lots located in close proximity forming an “island surrounded by streets”
In practical terms, usually characterized by homogeneity in structures and urban services, as well as socio-economic conditions of families
Can describe both poor and wealthy areas

5. Network of sewers that service a condominial settlement
Condominial sewers
Network of sewers that service a condominial settlement
Strives to be the most appropriate and efficient network given different topographical conditions or settlement patterns
Includes innovative condominial arterials
Do not follow traditional layout
Location of arterials decided by users
Connected to trunk sewers

6. …in planned neighborhoods

8. …in un-planned neighborhoods

9. Traditional vs. Condominial systems
Condominial sewerage systems represent approx 50% savings in terms of:
materials
extension of networks
installation
Condominial water systems represent approx 20% savings

10. The Brazilian Experience...
Many cities have incorporated condominial sewerage and water systems
Rio Grande do Norte
Pernambuco
Bahia
Rio de Janeiro
Brasília
Pará
...these systems provide service to all sectors of the population
