What will happen if you drain an inground pool?

Draining an inground pool without taking proper precautions can have several negative consequences, including:

Structural Damage: Underground pools are not designed to withstand the pressure of the surrounding soil when empty, and draining them can lead to structural damage. The weight of the soil pushing against the pool walls can cause them to collapse or crack, resulting in costly repairs.

Foundation Issues: Draining an inground pool can also impact the foundation of the pool deck or surrounding structures like the patio or house. The shifting soil due to the lack of water pressure can cause the foundation to settle or sink, leading to uneven surfaces, cracks, and further damage.

Groundwater Issues: Draining large volumes of water from an inground pool can disrupt the local groundwater balance, especially in areas with limited water resources or specific regulations regarding water discharge. This can potentially impact nearby wells, aquifers, and the overall water ecosystem.

Environmental Concerns: Emptying an inground pool can release various chemicals, such as chlorine, pH balancers, and stabilizers, into the surrounding environment. These chemicals can harm aquatic life and pollute local waterways if they enter streams or groundwater systems without proper treatment.

Erosion and Sinkholes: Draining the pool can cause the soil around the pool to become unstable and susceptible to erosion, leading to the development of sinkholes or depressions in the ground.

Damage to Pool Liner and Equipment: Draining the pool can expose the pool liner and equipment, such as pumps and filters, to drying out and cracking or damage from the elements. This can lead to costly repairs or replacements.

Local Regulations: In some areas, there may be local regulations or restrictions regarding draining swimming pools, especially during droughts or water shortages. Violating these regulations can result in fines or penalties.

To ensure the safety of your pool, surrounding structures, and the environment, it is always advisable to consult with a qualified pool professional before draining an inground pool. They can assess the specific conditions and take appropriate measures to mitigate potential risks associated with the process.
