Introduction RWH
The direct collection of rainwater from roof and other purpose built catchment, the collection of sheet runoff from man-made ground or natural surface catchments and rock catchments for domestic, industry, agriculture and environment use. The system can be categorized as small, medium and large scale.

Why use RWH?

• Utilising an otherwise wasted resource would contribute towards
• sustainable water resources management especially in cities.
• Domestic/Industrial benefits
• Supplement water for industrial, commercial, agricultural, institutional and domestic use.
• Independent water supply for non potable use.
• Rainwater collection will reduce water bills.
• Additional water for fire protection/emergency use
• Environmental benefits
• Minimizing discharges into drainage systems.
• Reduce soil erosion.
• Improvement of river management.

Advantanges Using RWH

1. For Environmental:

• Can be attributed due escalating environmental and economic cost of providing water by centralized water system or by well drilling.
• To reduce the ultilization of portable water with using the collection rainwater for non-portable application such as toilet flushing and garden watering
• Reduce the land erosion and flooding caused by runoff from impervious cover such pavement and roof.

2. For Quality Control

• Capable of providing a clean, safe and reliable water source if the collection system are properly built and maintained and water is treated appropriately for intended uses.

3. For Quantity Control

• Provide the small storage constructed on individual residential, commercial and industrial lot to serve a minor storm event.
