Some Aspects of Roof
Water Collection in a Subtropical Region
Nanyang Technological Institute, Singapore
The ever-increasing demand for water is making man look towards different means
of conservation and new methods of abstracting water. The concept of collecting
and storing rain water, an age-old practice, could prove to be an encouraging
additional source that could very well enhance the limited and apparently dwindling
supply of water.
In a city-state like Singapore, there are competing demands for use of limited
land area and, with the added rapid economic grow and industrial development,
there is an even greater demand for water. Singapore lies 8° north of the
equator, has an average ambient temperature of 26°C and a population of 2.3
million. With the twin assets of 70% of the population living in high-rise flats
and an average annual rainfall of 2 230mm , it would appear to augur well for
the harnessing of roof water as a supplementary source of water.
