There is so much one could write concerning water conservation. Everyone uses water. We all need it to survive and yet it's one of those things that we don't take a lot of notice of until we have to. As you know, we harvest and store as much water as we can on our property. It is used outside on the animals, chickens and garden. Inside, we use our town water supply but we are extremely frugal with every drop. Water is easy to use and waste. I found this list that shows just how much common household activities use. That is a lot of water running down the drain.
| Brushing teeth with tap running | 5 litres | 1.1 gallons |
| Flushing toilet on a dual single flush | 5 litres | 1.1 gallons |
| Flushing toilet on a dual full flush | 10 litres | 2.2 gallons |
| A load in the dishwasher | 50 litres | 10.9 gallons |
| A 5 minute shower | 100 litres | 21.9 gallons |
| Hosing the driveway | 100 litres | 21.9 gallons |
| A load in the washing machine | 150 litres | 32.9 gallons |
| Washing car with hose | 200 litres | 43.9 gallons |
| Garden sprinkler per hour | 1000 litres | 210 gallons |
There is another list of water usage here. There are level 5 water restriction in our capital city of Brisbane. People are required to use less than 140 litres per person. We use much less than that and we have found it quite easy to do it.
I think there are three ways you can go on this:
If you are living in an area with high air pollution or there are a lot of birds or wildlife that can get on your roof, you may be able to install a first flush diverter that will run-off the first flush of water from your roof, then divert the flow after that to your tank. This will help you with water purity if you intend to drink the water you harvest. Here is a guide to maintaining a healthy water tank.
General maintenance requires that you check for leaks and make sure your mosquito screens are in place and not blocked with leaves or other debris. You'll also need to keep your roof guttering clear of debris. If you own a plastic tank, every few years, whenever your tank is empty, or close to it, you should tip the tank over, hose it out and reconnect it. There is information about desludging and cleaning your tank here.
Size of various types of Australian water tanks are here, check the Slimline and Transport types too. The links are on the right. Mrs T, although these might not be available in Israel, it will give you and Mr T an idea of what is in common use here. There are space saving water tanks here.

You should cover your water tank as algae will grow in water that is allowed to sit in the sun. All openings should be protected from mosquitoes with fine screening.
How many of you are monitoring your water usage now? Can you read your meter? Although water meters are on most Australian homes I am aware that this is not the case in all homes. Do you have access to your meter? This is an important part of every simple life and I'd be very interested knowing how you intend cutting back your water usage.
I think there are three ways you can go on this:
- If you don't have a garden and only use water indoors, then the obvious thing to do is to work out a good way to cut down on your water usage inside your home.
- Like us, you could harvest your rainwater, store it in tanks and use it for all your outdoor needs and team this with a water conservation program inside.
- You could harvest rainwater and have your tank water plumbed into your home to flush toilets, or if you have enough water, for all your indoor needs. You would probably also team this with frugal water usage.

How can I make sure that my water is safe to drink? from here.
The following simple precautionary measures can significantly reduce the likelihood of harmful
microorganisms or chemicals being a problem in your water supply.- Collect and store your water so that contamination from human, chemical or animal sources is minimised. If possible, store drinking water in an above ground tank rather than in an underground tank.
- Ensure that surface runoff, channel water, irrigation water, leakage from sewer pipes, sullage drainage or shallow underground seepage cannot enter your drinking water supply.
- Make sure that any deep bore used as a source of drinking water is properly encased, with an above ground wellhead. A deep bore should ideally be located at least 250 metres away from any sources of pollution likely to affect groundwater quality.
- Do not collect water for drinking from recently painted roofs, timber roofs preserved with chemicals, roofs coated with lead-based paints or tar-based coatings, or parts of roofs near flues from solid wood heaters. Most other roof types will normally be safe for water collection, provided they are kept clean.
- Regularly clean your roof and gutter to remove leaves, animal or bird remains, dust and other debris. Install simple screens between your roof and the water tank.
- The first rainfall after a dry period usually collects most of the contaminants on your roof.
- Installing a ‘first flush’ or other diversion system will prevent this water from entering your water tank. This ‘first flush’ water can be stored separately and used for yard washing, garden watering or fire fighting.
- If your house is in an agricultural area where there is a risk of being oversprayed by aerial chemical spraying, divert the collection pipe from your rainwater tank to prevent any pesticides from entering the tank. Clean the roof or wait until after the next rainfall before reconnecting your drinking water tank to your roof.
- Maintain screens on the inlet and overflow openings of your water tank so that insects, small animals, birds and sunlight can not enter (this will also help to minimise the growth of algae).
- Regularly maintain your water tank and clean out accumulated sludge from the floor.
- Ensure that your domestic drinking water plumbing is completely separate from all other plumbing or pipe systems on your property. Use approved safe plumbing materials and ensure that all pipe joints are properly sealed.
- Disinfect your water supply to kill any harmful microorganisms.
You should cover your water tank as algae will grow in water that is allowed to sit in the sun. All openings should be protected from mosquitoes with fine screening.
