hi guys..

just curious for those that stay on landed property..

do you guys install or used a rainwater harvesting system ?

i'm currently looking into this, as currently the hot weather and "ever-increasing" water bills..

thought of using the waters for garden/wash car/toilet flush....

any comments on this topic ?

Most terrace/link houses don't have space to put big water storage or "tong air".

If you got space, all you need to do is just using the modify your gutter so that the water from your roof goes into the "tong".

Occasionally, you need to empty the storage and clean it up because the dirt will be collected at the bottom of the storage too..

Probably not wise to use it for flushing toilet or washing car, rainwater here is slightly acidic. Watering your garden and washing your porch is probably fine.

i've tried that, good 4 washing car porch, but not car wash, car tyre is exception.

space is still a constraint, coz of large volume of water.

and 2 other problems, dirt from the roof accumulating it gets dirty, (u may use some kind of filter)

and mosquito larvae, might get penalty for rearing them as pet and also spreading aedes

Harvesting rain water is a good idea because it is eco friendly. The black Balinese pot would be just nice.

My friend relates this to wealth accumulation. Believe it or not.

there is something call a first flush system , where by the first set of rain water isn't stored in to the tank..

the most acidic/dirtiest, see the site below for different kind of first flush system

well dirt and mosquito can be solve by installing this

and you pipe directly into an ENCLOSED TANK with a netted overflow pipe.. not an open air tank...

if you put it outside @ the backyard, the sunny day sun will mostly heat the tank and cook the stuff that is inside lol....

fengshui ?, but those pot can only store so much...


tank can be like those, so far the size/dimension and the amount of storage is quite nice/good

this is good, now i wonder whats the price, is it available @peninsula?

actually if you do a search on google there are quite a few documents for rainwater collection in malaysia and also some

paper by local uni professors and IR engineers..

another supplier,
bacfree

well i wonder if the topic starter had installed the system because im also dreaming to install it to my future home..

Grundfos also has rain water harvesting system.

nope.. no budget... if want then really install a 10k liter underground tank.. piped to all toilet and the garden for watering plants...

they make the pump or a whole complete system ???

If I am not mistaken, complete system but exclude those normal items like tank, piping, etc.

The later phases of Denai Alam by Sime Darby has rainwater harvesting system built-in by the developer.

Can read the owners' feedback on that thread.

Also thinking of doing it in my new house.

I've actually been asking around about a rainwater harvesting system. This is a reasonably new corner house. My main objective is not to save money but to have backup water supply when the mains go out, planned or unplanned.

It looks like there are two issues that usually come up. First is obviously cost, the people doing it out there will happily sell you at inflated prices, insisting you buy a pump for example when you don't even want one.

Second is the design of the house itself. My house for example has rain gutters coming down from all four corners of the roof, making it a bit more complex to reroute the water. The location of the tank itself is also a question, it's physically large (750l) and it's unclear how I can put the tank on the upper floor of my house when fully filled, the tank will weigh close to 800kg!

So as of now I'm not sure what I want to do yet. Will have to go visit the different showrooms to find out what I can get for my money first...

By 2014, all new house require to have Rainwater Harvesting System. New rule.

Rain water cannot be use for drink and cooking.

My neighbour setup a construction structure and put the tank ontop. At the car porch. The rain gutter flow in. And use the rain water to wash car porch.

I would said quite ugly.

I know rainwater cannot be used for drinking or cooking. I can buy drinking/cooking water in bulk, however I cannot (or would not) buy the same for flushing toilets or washing bathrooms for example which is equally important.

I'm quite worried about the ugly structure as well, which is why I'm still unsure about this setup now....

Just install an extra tank for backup. Make it auto backup system.

Unless you want to save ome water. But you still have to invest cheap to justify.
