Water tanks from stabilised soil blocks

There are inspiring examples that can guide the future. For example, Makerere University’s Faculty of Appropriate Technology operates a rainwater harvesting project that uses water tanks made out of stabilised soil blocks. The university has transferred the technology to a number of organisations in Uganda. In one district, for example, over 700 water tanks have been built for individual homes.^[1]

Key design points

• Screened inlet to prevent the entry of mosquitoes and debris.
• A first-flush device to minimize the entry of dust and pollutants which have built up in the atmosphere and on the roof.
• Cost is an important consideration. Currently rainwater tanks are being promoted and subsidized in places such as NSW, Australia. However, it is also claimed^{[verification needed]} that this is not a cost-effective use of funds, and water recycling (stormwater recycling or sewage recycling) may be more effective.
• Environmental impact should also be considered. The financial cost mentioned above partly reflects use of resources in building and installing the tanks. What are the most cost-effective options? Can adobe water tanks be made effectively without excessive leakage?^{[expansion needed]}
