For a long time now actors and investors have been using a lot of resources to implement housing, water and sanitation infrastructures. This is because many implementers including government agencies and utilities rely on conventional technologies only which are quite expensive and does not address the challenge of affordability.
Such investments remain an important part of an overall approach to urban sanitation for instance, but should be viewed as an instrument for service delivery, rather than as a solution in their own right. For example there is a risk considering sewerage as the only “proper” form of urban sanitation, where municipal or government officials tend to choose this option even when it is neither technically nor financially viable.
CCI and the federation have explored some of the technological and materials options that are affordable especially for the urban poor. These are:
Simplified Sewer System
Simplified sewer system is a low cost piped system used to collects all household wastewaters (WC wastes and sullage) in small-diameter pipes laid at fairly flat gradients. It is suitable for existing unplanned low-income areas and new housing estates with a more regular layout. Simplified sewer system offers the best solution of collecting and transporting all the waste waters from informal settlements where the sewer trunks have passed nearby or there is a nearby waste water treatment plant.
