Some Aspects of Roof Water Collection in a Subtropical Region

Adhityan Appan
Nanyang Technological Institute, Singapore

Introduction

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.
