Hi Ozak,

BP=Bandar Puteri or Bukit Puchong?

Bandar puteri

My house in Denai Alam comes with RWH unit. I got rid of it and connected my my tank outlet straight to the garden pipe.
The reason:
1. The tank provided is big and ugly. It also collects rain water (on top of the tank )and became a mosquito breeding ground.Also located near the exterior wall making it easy for theives to stand on while trying to break in.
2. Scared the pump which is located on the ground floor at the back of the house will be easily stolen.
3. It only services the garden tap which i hardly use.
4.Saving water by consuming electricity (pump) does not make environmental sense.


After a long hard thought got my contractor to dispose the tank and gave the pump and switch to my dad.

Mine no pump will be installed. I intend to do the manual and basic ones.

The Housing Ministry has actually issued guidelines to all the local authorities to implement the RWH system (SPAH) for all semi-detached houses,
detached houses and shops middle of 2012. The guideslines can be found here:

Most of the local authorities are still kelam kabut about it but are told to implement it anyway.

IMO, installing RWH system which involves pump which consumes electricity, require maintenance and installatiion cost does not make sense.
It defeats the purpose of 'going green', the objective being to conserve resources.

It is worthwhile only for double storey houses where you have the storage tank on the lst floor level to collect water from the roof and feed by gravity
to the wc's, garden taps, etc.

If you get acid rain in your area (industrial area especially), washing car with the acidic water would be harmful to the car body.

The enforcing is 2014.

But saw some new house deeloper already implement it. Those expensive house. Not sure the cheap house.

normally first 10 minutes of rain water is acidic..so need to drain it first, only then can collect it...rain water is "soft water"..

Rain water harvesting system normally come with a first flush device to drain off the first few minutes rain water.

Found this video.
Super-simple mechanism. The system only divert clean rainwater to storage tank after the "self timer" finished.

good info..i'm looking for a buttom to "like" it but this is not FB ...anyone building this system diy?

The system can be easily clone and DIY.
The only problem is to find the cone shaped PVC fitting.

Bill of materials:
● Cone shaped PVC fitting.
● PVC pipe, fitting & glue.
● Mesh filter.
● Hollow plastic ball.
● Dripper.

I still don't understand how it work. What the ball use for?

i think can get a big funnel, and cut it to fit a T joint.....

thing is to find a ball that can fit, n seal tight.....

How much roughly does it cost to install the above system?

this day, use 3d printer to design that simple stuff.

What do you mean by "that simple stuff"? Print??

I don't know, I'm not seller/installer.
The pictures captured from this video.

with understanding of 3d Printing, moulding and duplicate design getting more easier.

do google how 3d printer could help yr small design like this roof gutter filter.

Do you mean by using certain software to create the actual system out?
Kind of like tailor made the parts?

You can get the blue barrel (2nd hand) at

Less than rm40 (for 2nd hand unit). 210l. Not advisable for drinking water. Should be ok for gardening etc.
