I have also started to cut down usage of water and to recycle water in our household through:
1) Always have a small pail / basin in our sink to collect 'not so dirty' water after we wash our hands and rinse cups, plates and cutlery with the clean water from the tap. The recycled water will be transferred to another bigger pail in the bathroom, to be used for flushing the toilets and washing the bathrooms.
2) Filtered dirty water flowed out from the second outlet of our Panasonic Alkaline Water Purifier is now stored in a pail, for washing dishes and flushing toilets. In the past, the filtered dirty water will just flow onto the sink and into the drains.
3) Place a small pail inside the shower area. I have taught my girls to put the pail next to them and to rinse their body and hair as close as possible to the pail, so that the shower water can be collected in the pail. The recycled water from the pail can be used to flush the toilet.
4) Instead of a 1.5-hour washing machine cycle, I have since 2 weeks ago changed the mode to a 30-minute cycle, so that lesser water is used and electricity can be saved too.
5) No more washing of the balcony until there is no more water rationing. We just have to bear with the dust and dirt. We can always sweep instead of wash. Just have to close 2 eyes to dirt and imagine we are living in the 'kampung' !
6) Instead of flushing the toilet after every pee, I make my 3 girls pee one after another, followed by me and then I dump the pail of recycled water into the throne! Half a pail of water for 4 pees LOL!! Pressing on the flush button is now only reserved for big business!
7) Cut down on rinsing the cup with water before each use. How dirty can the cup be right?
8) In the event of a water rationing, I will have to resort to using disposable paper plates for meals. I know that this is not environmental friendly but heck, when there is not a trickle of water from the tap, you need to find alternatives and measures that will not add more stress to your bag of stress. And this is only temporary until God decides to let the skies shower.
9) I can only exercise on the days when there is water flowing from the tap. There will be no luxury to bathe twice a day on the days when the taps are dry. So I can only take a shower at night, just before bed. Again, think kampung-style living! LOL!
10) Use wet wipes to replace water for cleaning.
Please add to my list of measures to cut down on water usage if you have any good ones. It will be good for everyone who reads this post.
Pray tell that the water rationing exercise will be cancelled and that some better alternatives for the Rakyat will be in place by the government. Water is a necessity and cutting its supply will cause severe inconvenience to families with kids.

Filtered dirty water from the water purifier second outlet is now collected in a small pail, the water of which will be used to flush toilets.
