"While rainwater harvesting can solve water crisis, you need an electric pump to harvest rain.

It didn't make sense to me to save water but use electricity.

That was what compelled me to create Voda."

- Sit Heng Yeen



Voda’s inventor and an architect by profession, Sit Heng Yeen, received his education at the prestigious Architectural Association of London.


Sit’s idea of a practical rainwater harvesting system came about when his architecture submissions which weren’t equipped with such systems were rejected by the state council. This was following the amendment made to the Malaysian’s Uniform Building By Law in 2012 requiring newly built detached buildings, bungalows and semi-detached bungalows be equipped with rainwater harvesting systems.


Given the lack of practical systems in the market coupled with Sit’s deep passion in problem solving, he undertook a challenge. After extensive research & development and design works, he invented and patented the Voda Rainwater Harvesting System as a solution for his clients’ new developments.


He later founded Green Master Harvest Sdn Bhd, alongside a few partners, to make his invention available to the masses. He leads research & development efforts, rainwater harvesting advisory and oversees manufacturing operations of Green Master Harvest.

Recycling Rain

"The quantum is scary. If an average person flushes 5 times a day,

and an average home has 4-5 person and each flush is 6-7 litres,

that's up to 175 litres of overqualified water

for flushing."
