Water. Build a simple cisterna which is a water reservoir fed from the roof of your property or from a natural slope on the land. This will give you all you need for showers, baths, washing machines, toilets and the garden – and for free from rain water. It may be necessary to top up with “bought” water occasionally in the summer but water is cheap! Alternatively, sink a borehole and you can even sell some water to the neighbours.

How to make your water safe to drink:

Make well water, irrigation or river water safe and pure enough to drink. …

Poor quality water can also result in serious life threatening illnesses and also cause ear and eye infections and aggravate skin problems like eczema so why not bathe and shower in pure clean water instead. … Mains water suppliers use chemicals to kill the bacteria so this is left in your drinking water making it unpleasant to drink. … Water from a well or delivered by truck could contain a multitude of unpleasant and possibly lethal elements. This may not always be present and can vary at any time due to other pollutants. … When reservoirs are low more pollutants are confined too a smaller quantity of water so either greater quantities of chemicals are used to combat this or there is not enough used to deal with the contamination. … The solutions to all these problems have been solved by the unique matrix system developed by General Ecology and supplied By PurewaterSpain.
