Current water shortages in parts of the nation, especially as mentioned in the western US areas like Las Vegas, are requiring communities to be on year round water restrictions and will increase the need for a more efficient distribution method for pool covers so that more people will use covers and more water can be saved.

Studies have also shown its not enough to just cover your pool, you need a way to manage the cover. Builders can provide a free cover with the pool but if its hard to manage people will not use them. So I as an inventor have devoted the last 20 years of my life to help solve this problem.

Programs such as Water Smart in the Las Vegas area, and Water Sense sponsored by the EPA are dedicated to conservation. Additional programs by agencies offer pool cover REBATES at participating dealers tinyurl.com/ydc5ns4.

THE HALF COVER SOLUTION

To do our part in the fight for water conservation nationwide, I am advocating the innovative "half pool cover" distribution model to greatly assist in supplying stores everywhere with stock on hand. I don't make covers, just advocate increasing cover usage in a more efficient manner, and provide an invention to help home owners remove the covers otherwise they will not use a cover.

Again, studies have shown builders can give a free cover with the pool but if its a hassle to remove they won't use the covers. See more at solarfactory.com and our White Paper at solarfactory.com/dealers-welcome/white-paper.html

QUESTION: Why advocate 1/2 pool covers?

ANSWER: It's just a better way to distribute covers so more people begin to cover their pools to conserve water. Half pool covers cover pools IN SECTIONS LIKE PIECES OF A PUZZLE. No one has ever thought of this before. It's easier to handle too.

For more efficient distribution to stores, 1/2 pool covers in "4 sizes" can accommodate almost any size pool up to L-shape pools and are more compact to stock and distribute (ship) not incurring oversize shipping charges, so distribution is practical in contrast to full size covers in +50 sizes that are large and bulky.

A better distribution model will be helping to save BILLIONS of gallons of wasted water nationwide, by facilitating more covers being in stock directly at the stores rather than having to be special ordered and stocked in warehouses which takes considerable storage and costly overhead. And inventory planning will be much easier for the warehouses.

The benefit is it only takes 200 pools using a cover to save an entire 3.5 million gallon city tank of water because a pool left unchecked for a year can completely evaporate... and that's a lot of water wasted! Just fly over any city and count the pools.

WATER LOSS CALCULATIONS

In THEORY based on 2 MILLION POOLS

Here is the formula:

Length * Width * Average Depth * Multiplier = Gallons
Determine the Multiplier:
Rectangle, square, or free-form pool:multiplier = 7.5.
Round or Oval pool: multiplier = 5.9

So if in theory there were 2 million pools in CA and we average the aboveground and inground multiplier to 6.5; then average the pool size to say 12x26 and a depth of 5 feet (just a guess but probably realistic); then using the FORMULA: 12x26x5x6.5 = ~ 10,000 gallons of water per pool rounded down for easy calculation.

Now 2 million pools times 10 thousand gallons completely evaporating each year as a rate of pool water evaporation equals:

20,000,000,000 gallons of water is evaporating in CA alone...that's 20 BILLION GALLONS of preventable waste!

If a city water tank capacity is 3.5 million gallons then there are ~5,715 city water tanks being wasted in CA each and every year by uncovered swimming pools.

Now then, water savings via the use of inexpensive buoyant pool covers is easy to calculate given the evaporation rates in inches published by the National Weather Bureau. (grow.arizona.edu/Grow--GrowResources.php?ResourceId=208).

Once the problem with removal and handling these inexpensive covers has been solve (i.e. managing the covers in sections like pieces of a puzzle for odd-shaped pools) it is not equitable to neighbors without pools to watch their lawns dry up while neighbors with pools continue to waste water that could be prevented through use of pool covers.

Taxing those pools with a $50/year tax however provides some equity and those pool owners can recoup their costs via lower water and chemical costs, and the tax revenues can be used to hold down water rate hikes on the average user without pools.
