CONDOMINIAL SYSTEMSA response to the challenge
of universal sanitation

(December 2008)
DRIVING REASONS BEHIND THE MODEL
Developed over the past 30 years to address unmet demand, and motivated by:
1. Sanitation as a basic need
2. Large scope of unmet demand– 2 billion people worldwide without access to sanitation services– 100 million in Brasil
3. Lack of an appropriate model for cities to address large unmet demand in a flexible manner, with reduced investment ability, and various urban contexts
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
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
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
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
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
