It takes only 200 pools using covers to save an entire tank of city water. So why aren't all pools required to be cover when so many areas are experiencing water shortages, and rationing?
The answer is that for the most part only traditional rectangular (ish) shaped pools can use a cover because "full covers" are so bulky they require a deck reel for handling.
But there's a better way, to use HALF COVERS rather than full covers. With half covers almost any pool can be covered up to L-shaped pools. Our site shows how half covers work. We are not trying to just sell a product, but a solution. If there is a better way of doing something that saves billions of gallons of water, shouldn't we all advocate the solution?
Water Loss Calculation
Let's calculate the number of wasted city tanks of drinking water through evaporation by swimming pools.
SACRAMENTO: If using an average evaporation rate of 17,500 gallons/pool annually, it takes only 200 pools to waste an entire city tank of water. If Sacramento has over 50,000 pools, then Sacramento alone wastes 250 tanks of city water every year (or) 2,125,000,000 (that's BILLION) gallons of water every year!
What's that make you think about when they start rationing water and your lawn's going brown, while your bill's going up? Our 17,500 gallon/annual evaporation figure is probably conservative (other reports site 1.5"/week - wiki.answers.com/Q/How_much_water_evaporates_from_a_pool). There are evaporation figures for Australia in a report by Sealed Air sealedair.com/ap/en/library/articles/pool-water-usage.pdf. Multiply liters by .264 to get gallons. One average states over 86,000 liters per year, or over 22,700 gallons annually evaporates from the pool.
NATIONWIDE: If the nation has around 8.5 million inground swimming pools, then nationally we waste 42,500 tanks of water every year. This amounts to 42,500(tanks) x 3,500,000(gals) = 148,750,000,000 gallons of water annually in the US alone. Again, that's BILLIONS!
ABOVEGROUND POOLS TOO! Now approximate an additional 30% for aboveground pools to add another 45 billion gallons of water wasted and we are looking at almost 200 Billions gallons of water annually in the US ... WASTED. If you say "so what" to water conservation, think about the cost of energy used to process and create drinking water!
WORLDWIDE: Now think worldwide and help advocate that 1/2 pool covers are the SOLUTION for WATER CONSERVATION because Half Covers work on almost ALL POOLS...
