Materials and Technologies

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.

Our Approach:

CCI and the federation have explored some of the technological and materials options that are affordable especially for the urban poor. These are:

  • Interlocking Bricks

    Interlocking bricks use small amount of cement with large amount of dust. This addresses the issue of affordability for the urban poor

  • Simplified Sewer System

  • Trapezoidal blocks

    Trapezoidal blocks are cement sand kind of blocks which have a shape of trapezium used for toilets lining. They are using less cement hence reducing the cost of toilet construction.

  • Bottled walling technique

    Water bottle filled up with sand is an innovation aimed at providing low cost construction of toilets and housing, while contributing to environment management
