Lawn Rails For Trams

Water conservation
Maintaining a green lawn sometimes requires large amounts of water. This was not a problem in temperate England where the concept of the lawn originated, as natural rainfall was sufficient to maintain a lawn's health. However the exporting of the lawn ideal to more arid regions of the world, such as the U.S. Southwest and Australia, has crimped already scarce water resources in such areas, requiring larger, more environmentally invasive water supply systems. Grass typically goes dormant during cold, winter months, and turns brown during hot, dry summer months, thereby reducing its demand for water. Many property owners consider this "dead" appearance unacceptable and therefore increase watering during the summer months. Grass can also recover quite well from a drought.
In the United States, ~50-70% of residential water is used for landscaping, most of it to water lawns.A 2005 NASA study showed that there are over 30 million acres of irrigated lawn in the US (128,000 km2 or 12,800,000 hectares), three times the area of irrigated corn.
“That means about 200 gallons of fresh, usually drinking-quality water per person per day would be required to keep up our nation's lawn surface area.”
