Conserving Water in California
The Problem with Water Evaporation
between Hollywood Hills and San Pedro, “from pools shaded by leaf-covered pergolas in Santa
Monica to ones surrounded by chain-link fences in Alhambra”. The same researcher identified
that the average size pool in California is about 430 sq ft; at an average depth of 5.5 ft, the total
average volume equates to 18,000 gallons of pool water. Using these numbers it is estimated that in the swimming pools in Los Angeles alone there is over 775 million gallons of water being stored in those swimming pools.
In similar findings, the California Spa and Pool Industry Education Council estimates that a pool
evaporates a 1/2 inch to 2 inches of water per week. By those calculations, the average swimming pool in California is losing around 19,500 gallons of water per year to evaporation alone.

Calculating Pool Volume
Square or Rectangular Pool
Length x Width x Average Depth x 7.5 = Volume in Gallons
3.14 x Radius squared x Average Depth x 7.5 = Volume in Gallons
The Solution to Pool Water Evaporation
from swimming pools, very effectively conserving water. This one simple addition to every
swimming pool in the state has the potential to save millions of gallons of water that is currently being needlessly wasted. As an added benefit, pool owners can save themselves much of the time and energy committed to maintaining adequate water levels required to ensure safe and effective pool equipment operation.
The US Department of Energy shows that savings of 50% - 70% of evaporation can be achieved by using a pool cover. There are three main varieties currently available: plastic or bubble blankets, safety covers and liquid solar covers. Traditional plastic blankets can be difficult and time-consuming to apply, and safety covers are often considerable financial investments to properly customize to each swimming pool. Liquid pool covers were developed by Flexible Solutions over 20 years ago and offer a safe, inexpensive and convenient alternative. Their products are offered under the brands of HeatsavrTM and EcosavrTM – the original liquid solar pool covers.
Liquid pool covers have been proven to reduce water evaporation by 30% - 50%6. Based on the
previously noted studies, swimming pools lose the equivalent to their entire volume in water
evaporation each year. To estimate the potential for water savings on any pool, use the following formula:
30% Annual Water Conservation
Pool Volume x 0.30 = Average Water Conserved
Annually in Gallons
50% Annual Water Conservation
Pool Volume x 0.50 = Average Water Conserved Annually in Gallons
If we base our estimations on the projections noted within the studies, the average 18,000
gallon pool in California has the potential to save up to 9,000 gallons of water annually simply by using a liquid pool cover.
Using a Liquid Pool Cover
The products only require either a simple weekly dose from a bottle of HeatsavrTM, or the addition of 1 Ecosavr fish per month. EcosavrTM is a patented delivery device for dispensing the HeatsavrTM.
If every pool in Los Angeles began using a HeatsavrTM or EcosavrTM in their pool right now,
the annual savings could be as high as 375 million gallons of water in the L.A. Basin alone.
Just imagine the savings potential across all of California.
California has been having issues with its water crisis for so many years now. These tips are great; they can help pool owners in California enjoy their pool without the guilt. The temperatures are just at too high levels, and cooling in a pool will help lessen heatstroke incidences. Liquid pool covers are great as it can still make your pool easy to use without having to worry about evaporation. Hope a lot of pool owners will realize the potential it will give them for cost savings as well as water conservation.
