Water is recycled in nature by the water cycle.
The number of people on earth is increasing rapidly, so we need more and more fresh water. If people pollute the world’s drinkable (potable) water, we will have less and less to drink. We have to find ways of using water more than once, meaning re-using it. Used or dirty water is cleaned at a waste water treatment plant.
Waste Water Treatment Plant
Treated water is re-used by many industries, like factories. They use water to cool their machinery when it gets very hot from working for a long time. Sometimes, municipalities use the water from the waste water treatment plant to irrigate sports fields. Recycled water may be used to flush toilets and to irrigate lawns. Farmers may use recycled water for watering their crops (irrigation) depending on the type of recycled water. Recycled water is also pumped into temporary storage areas (recharge basins) before it goes back underground.
“Thousands have lived without love, not one without water.” — W.H. Auden
When we talk of flood control, we usually think of dams and deeper river channels, to impound the waters or hurry their run-off. Yet neither is the ultimate solution, simply because floods are caused by the flow of water downhill. If the hills are wooded, that flow is checked. If there is a wetland at the foot of the hills, the wetland sponges up most of the excess water, restores some of it to the underground water supply and feeds the remainder slowly into the streams. Strip the hills, drain the wetlands, and you create flood conditions. Yet that is what we have been doing for years.Hal Borland
