Pool Evaporation

Pool Evaporation

Postby Chris&Maggie » Sat Oct 12, 2019 4:47 pm

We have a new pool, but it seems to lose about 2 inches a week at this time of year, pool is south facing so gets the sun. Size is 8 meters by 4 meters. Would very much appreciate your kind comments. Thanks

2 inches x 8m x 4m = 1600 L divide by 168 hours = 10L water an hour.

confimed by gs = Θ A (xs - x) / 3600

POSSIBLE SOLUTIONS:
  • reducing the air velocity above the water surface - limited effect
  • reducing the size of the pool - not really practical
  • reducing the water temperature - not a comfort solution
  • reducing the air temperature - not a comfort solution
  • increase the moisture content in the air - may increase the condensation and damage of the building constructions for indoor pools
  • remove the wet surface - possible with plastic blankets on the water surface outside operation time. Very effective and commonly used

you need a white pool cover......or a very large gazebo

Interesting that you went from imperial to metric in your wonderful calculations, to come up with 10 liters an hour. Where you a statistician for the Government by any chance. Thanks for your kind help

Sounds like a leak somewhere to me, either in the pipework or the pool structure itself ...
You say its new, so I'd get the builders back to check it over ...

Definitely get them back to check it out, 2 inches water loss is not normal at any time of the year for a pool that size.

Put a bucket on the top step level with water level in pool. Fill it with water. If the pool goes down more than the level of water in the bucket you may have a leak.

First responder was almost right with his sum, if it is 2 inch (5cm) drop in a week, it does equates to approx just under 10L an hour, 1600L in a week.

Even though the answer is only approx, and assuming the pool is not full of swimmers taking water out on their bodies and splashing it over the sides? it certainly sounds a heck of a lot just for evaporation.

The cost of any repair will become a saving against all cost of the water you are losing each week until it’s done.
