FAQs About Rainwater Harvesting Malaysia
01
Is rainwater harvesting mandatory in Malaysia?
Yes, under the SPAH (Sistem Penuaian Air Hujan) guidelines, installing a rainwater harvesting system in Malaysia is mandatory for bungalows and large commercial buildings to prevent flash floods and save water.
02
How much does a commercial rainwater system cost?
The cost varies significantly based on tank capacity and filtration complexity, but businesses often recover the investment within 3-5 years through lower utility bills.
03
Can I use harvested rainwater for irrigation?
Yes, rainwater harvesting irrigation systems are ideal for landscaping and agriculture because rainwater is free of chlorine and salts, which promotes healthier plant growth compared to treated tap water.
04
Do you install systems for high-rise buildings?
Yes, BACFREE specializes in designing gravity-fed rainwater harvesting system for high rise buildings, allowing collected water to be distributed efficiently for toilet flushing and common area cleaning.
05
What is the main benefit for industrial factories?
An industrial rainwater harvesting system provides a massive backup water source for cooling towers and production cleaning, ensuring business continuity during municipal water cuts.
06
Is collected rainwater safe to drink?
Raw rainwater isn’t safe to drink immediately due to potential contaminants from the roof or air. However, if your rain water harvesting system is equipped with BACFREE’s post-filtration and UV sterilization modules, the water can be treated to meet safe drinking standards.
07
How complicated is the installation process?
A professional rainwater harvesting system installation involves connecting gutters, first-flush diverters, storage tanks, and pumps to your building’s plumbing. BACFREE manages this entire end-to-end process to ensure your system integrates seamlessly with the municipal backup supply.
08
Does the system require a lot of maintenance?
Modern setups like the BACFREE Vortex series utilize a self-cleaning rainwater harvesting filter system, which drastically reduces maintenance needs. We generally recommend a simple inspection every 3 to 6 months to ensure gutters remain free of leaves and debris.
09
How does this system help with Green Building certification?
Installing a building rainwater harvesting system significantly contributes points towards your Green Building Index (GBI) or GreenRE certification in Malaysia. It demonstrates a commitment to sustainable development and efficient resource management.
10
What components make up a complete system?
A complete rainwater harvesting tank system consists of the catchment area (roof), a filtration unit (to remove debris), a storage tank, and a pump distribution system. BACFREE customizes these components to fit your specific property layout, whether it’s a home or a factory.
