Nice PE water tank cost around RM 1500 for 200 gallon or you can get cheap poly tank for about RM200 but not very nice.
You also need a diverter and pump (optional). I am also looking around for rain harvesting and total cost is about RM2000. Dunno is it really worth it or not. |

I think that should be the first question. What do you want to harvest the water for, only then we know the cost and its value.

I think before that you will need a rain gutter system to harvest the rain. Which mean the amount of harvest will be depends on the amount of rain fall on your roof. Rain gutter system cost is depend on the length of the rain gutter and the type of rain gutter. G.I rain gutter RM12/ft & Stainless Steel RM25/ft, UPVC pipe 3" RM4/ft,4" RM5/ft. If you want a water pump system I think will cost around RM2000 - 3000 or more, else you only need to harvest the rain to your water tank and take it out manually with buckets for use..?

My friend did a DIY for his rain water harvesting solution, but it was all done at his backyard. Basically he asked the contractor to divert the water from the roof into 2 large 100 gallon tank at the back. The tank he converted it by adding a pipe between the two tanks so that it shares the water and it becomes 200 gallons in total and an external pipe. Mainly uses the water to either water the plants behind and clean the back porch area. He has a large space at the back of the house, almost 20 feet.

every once in a while, you need to clean up the tank.. because all dirts will accumulate in the tank.. and if there's any leaves or tree branch that land on your roof, it will go into the tank too.. So, it needs maintenance..

QUOTE(eclipse-space @ Sep 13 2011, 01:09 AM) Harvest for WC, below something need to look into. 01) Filtering the rain water 02) Where you want to store the water? 03) Redirect pipe for WC, in case your harvest tank is empty 04) Pump, for pumping water to first floor WC. |

Its possible if our locals have the adequate expertise. But we are too theory like we cant do a real thing. Architecture body have not really emphasize on it..
Its like they dont rectify the design need of sustainability; prefer hype it like the world now. |

I believe individual residential unit doing water harvesting is not viable.
Construction site and factory lot might look more feasible to do it. |

Maybe specify the budget and see if is doable. Can cost up to many thousand for proper system. I know new building in Singapore collect A/C condensate water for plant and w/c and many non drinking purpose.

The government is planning to impose this condition on new development.
Read here Most developer selling high end properties are using this as their selling point. |

I thought you just need to do this
Get a tank, Install pipes from to roof to the tank. Add some Denggi/Aedes mosquito poison to the tank water once in a while. Wash the tank regularly. Get Mangkuk type baldi to get at the water. Ta daaa..... rainwater harvested. Cheap and Simple |
