Recycling rainwater

With a rainwater harvesting system, we can all contribute towards a sustainable future.

WITH global warming and the recent change in global weather patterns, it is likely that rainfall patterns will continue to change, bringing shorter but heavier bursts of rain which causes flash floods and soil erosion.

In fact, rainfall recorded in some parts of Malaysia has shown a marked increase in the last five years. Commercial and household water consumption has been increasing steadily in the last century, and as the climate warms, other usages of water will increase.

New ways will have to be found to reduce, reuse and retain water. We can no longer assume that there is an endless supply of water even in a country with a high average rainfall per year like Malaysia. This is evident from the occasional water rationing as well as the price increase of the municipal water supply.

This is where rainwater harvesting and recycling comes into the picture. With water charges at the present level, the payback time on such a system is typically 10-20 years.

If you consider commercial properties with large roof areas and high consumption of non-potable water, the payback time can be much shorter. But the advantages go beyond the financial aspect as rainwater recycling benefits the environment as well.

Collected and filtered rainwater can be safely used to flush toilets, water plants in the garden, wash clothes, wash the car and general cleaning.

As the water is “soft” and chlorine-free, it is suitable for washing machines as it reduces the amount of detergent required. It can also be used to wash your skin. It also does not leave unsightly scales and stains.

Advantages of rainwater

With a rainwater harvesting system, we can all contribute towards a sustainable future. A rainwater harvesting system can provide water for non-potable purposes.

By substituting municipal water with rainwater for non-potable usage, we can halve the amount of municipal water used. Therefore, collected rainwater can make an important contribution to our dwindling municipal water supply.

Roof rainwater can be of good quality but it may require minimal treatment for non-potable usage. As rainwater may be contaminated with bacteria, it is often considered unsuitable for drinking without any prior treatment.

Rainwater harvesting also helps reduce your water bills. Besides, it can provide an alternative water supply during rationing or interruption.

A rainwater harvesting system also enhances the value of your property and can satisfy the water requirements of various levels of certifications for a sustainable home. It can form part of the rainwater management scheme, by reducing storm-water run-off, reducing or mitigating the possibility of flash floods.

Bacfree ventured into the rainwater harvesting industry in Malaysia in 2007. In 2009, it was appointed the Malaysian and Singapore partner of WISY AG of Germany, an industry leader in rainwater harvesting

Bacfree provides rainwater harvesting systems that are fully compliant with Malaysian and international best practice guidelines.

All its Rainwater Harvesting Systems are designed in compliance with the following Rain Water Harvesting System Design Guidelines: Department of Irrigation and Drainage (DID) Malaysia and British Standard BS 8515:2009 Rainwater Harvesting System – Code of Practice.
