How do you run a manufacturing plant in a city without electricity, usable water or natural gas?

"Our desalinization plant turns out fifteen thousand gallons of usable water on a good day," she said.

Where there are restrictions, recycle usable water especially from cooking and dehumidifiers.

It extracts any remaining usable water and then removes solid waste.

Humans are depleting the earth's store of usable water at a rate that will soon threaten our food supply.

It's built to make up for the loss of usable water.

At that rate, officials estimate, there will be no usable water left in 20 years.

And since tanks are generally not filled to capacity, the usable water in a holding tank usually ranges from 3,500 to 4,500 gallons.

It holds back 167 million m of usable water.

Part of the plan included turning grey water into usable water to encourage resorts to develop.
