Can the rainwater used to wash car?

I would like to contribute a little to this topic. I hope the interest is still high among those who are environment conscious.

One of the most difficult thing with rain water harvesting implementation in Malaysia is the lack of industry players and lack of government support. Nonetheless, there are a few companies that do offer the product but due to the cost, many are deterred.

I have actually inquired from the 2 companies mention on this thread which are basically DD Techniche and MyHomePalm. Both are located at Subang Jaya and Puchong respectively.

For a homeowner like myself, the biggest turn off is the high price of installing a basic rain water harvesting setup. For a setup to be functional, 2 main part are required for RWH. The leaf eater and first flush diverter. Both these device unfortunately seem like a simple device and does not seems to cost a lot but are sold at a premium. The rest of the devices such as tanks are easily available on the market.

The pricing by the vendors below

DD Techniche  - 3P Technik Filter Collector is both a leaf eater and first flush system. The cost is RM450
MyHomePalm - Leaf Eater Rain Head. The cost RM799. No price on first flush. But looking at the price of leaf eater, the first flush will probably be more.

After a long search, I have manage to find a RWH vendor from Australia that sells a combo product as above. The price is AUD$70 leaf eater + first flush + AUD$50 for air freight. That is total AUD$122 or around RM380.

The vendor did mention if I do a bulk purchase, like 20-30 units, he would propose sea freight which should at least reduce cost of shipping by half.

Any takers?

count me in....   is it easy to install? anybody else..i think this is cheap...hope we can get more people and get more discounts

Count me in also....been looking for a rain harvesting system for my new home 

i am interested to get this RWH for my new house too.
Can someone share their setup? I will only be using the harvested water for my WCs.
My plan is to install the system on top of the roof - collect water coming down from the roof into a separate tank.
From the tank, there will be pipes going to each individual bathroom's wc.
Since it is only for WC, do I really need the first flush diverter? Heck .. who cares if the water is a little dirty, it is for flushing the toilet anyway.

I will have another tank for shower etc.

I also need to know how do I top up the water in the rainwater tank when it is down to certain level - I am trying to avoid using a pump here.
Possible or not?

I think it is possible if your tank is below the level of the rain gutter outlet level so the water can flow into the tank.
But I think you still to to use some sensors for the tank level detection.

My opinion for the leaf eater is that, since the leaf eater is install after the outlet of the gutter which is middle way of the piping.
How if the leafs stuck in the gutter..? :s

Err.. if water dirty, stain your toiler wor... 

Stain the toilet is not a big problem. It is the bacteria will infect your toilet is dangerous.

Pour a cup clorex every week into the tank.  ;-)

This RWH system is not cheap. Normal RWH for house cost rm5k+. I don't see it save in term of buying cost and running cost.

The system have rain water/leave separator, a tank and pump. The tank have a backup water from main pipe incase rain water running low. Just a normal ball valve were you see in most of the water tank.

Without a pump, how to flow the water to the WC? Unless your tank is above the ceiling and not higher than the gutter rain collector.

Here the example of the RWH I taken from some new house. This tank is locate at the 2nd floor. Without pump, water can't flow to the 2nd floor WC.

i think shit got more bacteria than rainwater ler. just make sure the toilet is clean.
i think it is ridiculous flushing the toilet with treated water. the whole idea of RWH is not to save money ...
i just thought i should do something to help the environment without costing me too much of course.

but i heard that JUSCO/AEON management have practised this RWH for toilet few years oredi and they save A LOT!

I plan to DIY a rain water harvesting storage. But first, i need a plastic container like this in the photo. Anyone can give some pointer where to get this and how much does it cost? preferably shop near Puchong or Klang Valley area.
