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 well known that automatic pool cover can reduce water evaporation by up to 95%, yet less than 30% of pools are using covers. The current limitations imposed by full covers for the most part boils down to two problems.

The Twofold Problem

First, full covers are difficult to stock. Full covers are bulky and must be stocked in 50 or more sizes requiring a sizable amount of floor space to have covers on hand for the myriad of pool sizes.

If a size goes out of stock, the customer has to wait until the warehouse reorders another truckload of covers. This distribution and stocking problem severely limits the available stock on hand at any one time and prevents the customer from being able to purchase on demand.

Second, full covers for the most part fit only rectangular shaped pools. Covers initially come off the production line as sheets in rectangular shapes and are heat seamed together for various widths.

They can be further cut into oval or round sizes, but nevertheless most of the pools built today are irregular free-form shapes and custom designs.
