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.

that's why the construction of this RWHS is so few...the issue of course with the physical architecture of the tank itself...i guess maybe the best solution is to put the tank to the underground

New ruling probably apply to high end houses only next year. If all houses have to fix one, die-loh. Pump is not cheap. House prices already high enough to kill.

I plan to fix one in the back, water from gutter, rough filter, use small pump to set up automatic watering system for plants. Still planning stage.

Hi, why exactly is rain water not suitable for drinking or cooking? If it can be routed through a filter, wouldn't it be consumable?

what kind of filter ?? do you know how dirty the air is ? that is why rainwater harvesting is not suitable for drinking..

unless u pipe it though multiple filters and what not.. to clean and purify it

You might have a point...but think about it, if that is the case, how has mankind survived before the advent of chlorine? How did man survive from drinking the rainwater before we started having bodies like SYABAS?

Back then the air was not so polluted. The rain these days is really acidic with all the pollution especially when we get the annual gift from our friendly neighbouring country.

Bought a 0-lot bunglow and the developer provides the RWHS. If not mistaken I saw the tank at the roof, haven't really explored yet. It will def help to water the garden and washing the car porch.

i've set-up a very simple RWH system.

- buy 210 litres second-hand barrel (make sure used to contain food stuff e.g. CPO etc).

- buy the plastic connectors between the gutter and and a simple L junction. Ensure you also get some pipes long enough to fit the L junction to your barrel.

- drill a hole in the barrel and attached a tap

- cut the gutter, and attach the L junction.

For my roof, it takes about 15 to 20 minutes to fill up the 210 litres barrel. i have a few of these barrels.

For now, i use it for gardening.

My next step is to get a filter system / first flush system. The vortex filters looks beautiful but it cost several hundred ringgit (for the cheap one!). WISY's vortex filter is RM1,400. too much.

i've googled and it seems that UK and Australia's equipment are cheaper (first flush, and leaf eater) so i've got to look for friends there !!

just some sharing to encourage all.

i'm also trying to learn so please let me know if any sifu has some good idea or cheap equipment to improve the system !!

I am just propose by the rainwater harvesting system. What i think it is not bad. Maybe will consider to install in my new house. It is fully automatic system (doesn't need to do maintenance ourself). Can close the system during hazy season and etc. Anywhere, below is the website. Further information just look for the sales person which call Jeffery.

Any updates on user experiences?

Is Rainwater Harvesting practical ? yes and no

Yes. I'm doing it for my house. 100,000L underground storage, planning to supply all the toilets and also to supply the washing machine. Filtered of course. Practical or not it depends, I built a new house so for me it was just digging a hole. If you have a house already, very hard to find a place to put your storage tank and for the plumbing too.

I guess you need to use water pump motor from the underground storage to feed water supply to all toilets and washing machine.

Yeah, that's true. Pumping it with the water pump.

Didn't see these videos until now

With all the current water shortages, I guess it will be a wise decision getting your own water supply, at least to flush the toilets.

You have to makesure the water is free from bacteria etc.

Not eye see clean water.

Run it through a filter just like you would do for the government piped water. That's what I did for mine.

How viable is this system for a local terrace house - is it worth the initial cost?

Any VODA customers here can share some reviews?
