Every year swimming pools are wasting billions of gallons of water that can be saved. This paper addresses the problems with the current use of full pool covers and how half covers are the solution to pool water conservation.
It is known that pool cover can reduce water evaporation by up to 95%, but less than 30% of ponds use cover. The current limits imposed by the full closure mostly come down to two problems.
There are various types of automatic pool covers & pool cover reel/roller for inground pools.
First, full cover is difficult to store. The full cover is thick and must be filled in 50 or more sizes which require floor space large enough to have a cover for a myriad of pond sizes.
If a size runs out of stock, the customer must wait until the warehouse rearranges the load of the other truck. This distribution and inventory problem severely limits available stock at one time and prevents customers from being able to buy on demand.
Second, the full cover for the most part only fits a rectangular pool. The cover originally came from the production line as sheets in the form of rectangles and heat put together for various widths.
They can be cut further into oval or rounded sizes; however, most of the ponds built today are free-form irregular shapes and special designs.
To accommodate the shape of the free-form pool, customers must repeatedly exaggerate the cover which means ordering an even larger than needed cover and cutting the closing cookie into the free-form pool using the inside of the pooling container as a guide. But this can produce a lot of waste.
