The sports world uses tons of water every day. Irrigation, public restrooms for spectators, cooling towers, etc. They are also doing a number of things to do their part in conserving water by:
2 - Designing water efficient landscapes around stadiums or property. This is done by eliminating plants that need frequent watering.
3 - Recycling used water. In many cases, the recycled water is used to water playing fields, just one of many possible uses.
4 - Installing more efficient dehumidifiers to reduce ice melting at ice rinks.
5 - Switching to high efficiency fixtures in restrooms:
a. High efficiency toilets use about 1.28 gallons per flush, a much better alternative to the 3 to 5 gallons per flush of older toilet models.
On another note, many question whether water bottles conserve water. In all reality, water bottles are wasteful and detrimental to the environment. It actually takes about a full bottle of water to produce one empty bottle. Then it is filled.
1994 was the year that federally mandated low-flow showerheads, faucets, and toilets began to appear on the scene in significant numbers.
