Sewage systems of residential units were constructed as a single system in the past. Tribal sewers of most cities are now congested. A new built-up area is situated to a greater distance from the historic centre. Reconstruction investments of tribal sewers are expensive. Consequently, there are strong pressures to limit the runoff of rain water from the newly constructed buildings at the edges of cities. Therefore the sophisticated use of alternative supplies of water, such as the purified waste water from households and capture rain water is essential, to help reduce water consumption. Reasonable rain water management leads to maintain or recover a sound and sustainable water cycle. This involves retentions, infiltrations, vegetation strips, paving and design techniques, and so on. Changes in the amount of hard (impervious) surfaces in urban areas have significantly altered the way rain water moves over, and infiltrates into, the land.
