If you live in the Southwest United States and own a swimming pool one of the biggest issues you are going to deal with is calcium hardness. This issue isn’t something that most people are aware of because anytime you have a large body of water and are subjected to evaporation especially in warm climates, calcium levels will rise in swimming pools. This happens because as water evaporates, the hardness minerals remain in solution and increase over time. As hardness levels rise, it’s highly recommended to change out the water in your swimming pool. What people don’t realize is there are major risks and dangers anytime you remove water from inground swimming pools. Some of those risks are summarized below…

  • In-ground vinyl liner swimming pools are the most dangerous to drain because the older pools may not have been built structurally to hold back the weight of the dirt against it when the pool is drained. When the pool is drained it can cause the walls to collapse or groundwater can cause the liner to float; neither of which are good for swimming pools!
  • In-ground, concrete pools are built structurally to withstand the weight of the water pushing outward on the shell, and that water weight helps keep the shell in the ground. However, if the groundwater is high enough, it can actually push the entire pool out of the ground.  Once a pool has popped out of the ground it will not go back down!

  • In-ground, concrete swimming pools can also crack when the temperature is above 70-75 degrees and the surface of the swimming pool doesn’t remain wet.

With that said, there’s always going to be a risk when you empty out a swimming pool. In the Southwest United States, where drought conditions are on the rise, the simple and easy answer is to not drain your pool but recycle it instead.

At Pure Water Industries, we invented the “Puripool Process” which is an alternative to draining a swimming pool by using mobile Reverse Osmosis (RO) Filtration to lower calcium hardness, total dissolved solids, and other issues without draining the swimming pool. By using this technology the water level in the swimming pool never changes, it takes all the risks out of draining a swimming pool and provides you with a much better end product than a typical drain and refill.
