Couldn't our bath water be cleaned after use then re-used, Same for sink water?

Question

Via a filter, NASA can clean even diseases and virus' from water, so why don't we do this to help waste of water?

Thanks.

Answer 1

Yes its possible but you need some filters, cleaners, and some chemicals to get that done...

Answer 2

Water is re-used, the plumbing system dumps it all out and then it is filtered and reused.

Answer 3

I use it on the garden and to flush the toilet

Answer 4

Depending on where you live......it is.

Answer 5

try this care fully open your freezer and breathe into it this is one way to show you how air born water can be condensed so imagine if you had a tank big enough you could take the water vapour cool it and have fresh water

the carbon footprint would be horrendous

Answer 6

A very wealthy man wanted to build his house on the top of a mountain with no water available.  At great cost, he haul water by truck to the top of the mountain.  All the water used for bathing, cooking, washing clothes, and similar activities is collected, purified and reused.  All human waste is deposited in a composting toilet so there is no waste of water flushing the f***s away.

By the time water is treated by the sewage treatment plant, the water coming out of the plant is typically cleaner than the water taken into the water treatment plant to produce drinking water!

So yes, with proper precautions there is no reason why water can't be reused.  One reason is the idea of drinking water that has been "used" to flush the toilet!  But if you think about all the major cities along the major rivers in the USA, people are undoubtedly drinking "used" water!

Answer 7

maintaning the filters and chemicals is much cheaper when it is centralized.

If you want to sanitize and reuse your water, feel free!

Answer 8

It can be, and is.

This is called a "Greywater Reclamation System". The simplest version is to use used bath and sink water to fill toilet cisterns, but more complex versions have also been developed which allow it to be used to irrigate gardens, etc.

A really effective chemical and physical filtration system, or distillation, might allows the water to be re-used as drinking water, but this is likely prohibitively expensive for everywhere except the most water-deprived of places.

Answer 9

It can be and is. Some houses have systems to filter this "grey water" for uses such as flushing toilets, which do not require potable water. Even when there is no such system, the used water, both grey and black, goes either through a septic system to the ground water or via a sewer to a treatment plant. After going thru the plant, the water is discharged to a stream where it travels to the intake of downstream drinking water plants and treated again to make it potable.

Answer 10

you would think that water is used once then just thrown away some how?

water is reused
