Why Emptying Your Pool Could Cost You Big

Emptying your pool might seem like a quick fix, especially when it’s looking worse for wear during winter. But as our pool expert Will explains in this post, it’s not the best move for a few reasons. “Water isn’t just there for swimming—it’s what holds your pool together” Will states. “Draining it can mess with the structure, causing walls to weaken, crack, or even collapse”. Additionally, Will highlights the danger posed by groundwater pressure, which can lead to uneven stress on the pool’s walls or even cause the pool to rise out of the ground.

And let’s not forget about the environment. Pool water often has chemicals that can harm ecosystems if they’re let loose.

Then there’s the money side of things. Fixing structural damage and dealing with environmental issues can cost a lot. So, it’s smarter to look into other options, like regular maintenance or getting professional help. Will says, “Only think about draining your pool if it’s absolutely necessary, like for an acid wash”. And even then, take precautions to avoid damage. So, before you start emptying your pool, consider the long-term effects and go for sustainable pool care methods instead.

Consequences of Emptying a Swimming Pool

Structural Damage

One of the primary concerns when emptying a swimming pool is the potential for structural damage. The water in a pool provides essential support to its walls and floor. When the pool is emptied, the absence of this support can lead to structural instability. Without the counterpressure from the water, the pool’s walls may experience excessive stress, increasing the risk of cracking or even collapse. This structural damage can be costly to repair and may compromise the safety of the pool.

Groundwater Pressure

Another critical factor to consider is the influence of groundwater (or hydrostatic) pressure. Swimming pools are typically built with measures to counteract the pressure exerted by groundwater. When a pool is emptied, the balance between the water inside the pool and the surrounding groundwater is disrupted. This can result in uneven pressure distribution, causing the soil around the pool to shift. In extreme cases, it may lead to ground subsidence, where the ground sinks or collapses due to the changes in pressure or the pool can rise up out of the ground!

Environmental Impact

Emptying a swimming pool can have adverse effects on the environment. Will stresses the importance of responsible water management. “Pool water contains various chemicals used for sanitation and maintenance and these can harm ecosystems if they’re let loose” he explains. When released into the environment, these chemicals can pollute natural water sources and harm aquatic life. Additionally, the sudden influx of water into the surrounding ecosystem can disrupt the balance of local ecosystems, affecting plants, animals, and microorganisms.

Cost Considerations

Repair and maintenance expenses

The structural and environmental consequences of emptying a swimming pool can result in significant expenses. Repairing structural damage caused by pool drainage requires professional intervention and may involve extensive reconstruction work. Similarly, addressing the environmental impact of chemical discharge entails costly cleanup efforts and restoration projects. These expenses can quickly add up, making pool drainage a financially burdensome option.

Environmental remediation costs

In addition to repair and maintenance expenses, pool owners must consider the costs of environmental remediation. Cleaning up chemical discharge and restoring affected ecosystems can be complex and time-consuming processes. Hiring environmental specialists and acquiring the necessary permits for remediation efforts further contribute to the overall costs. Considering these financial implications, avoiding pool drainage whenever possible is a prudent choice.

Cost to rebalance 

Costs associated with rebalancing your pool after draining can add up quickly Will says: “Not only do you need to invest in a submersible pump to remove the water, but you’ll also incur expenses for refilling the pool with tens of thousands of litres of water, typically at a rate of approximately $5 per thousand litres”. Additionally, once the pool is filled, you’ll need to invest in rebalancing chemicals to maintain water clarity and sanitation, which can cost up to $1,000 depending on your system. And if you’re considering additional work like an acid wash or resurfacing, be prepared for significantly higher costs.

Alternatives to Emptying a Swimming Pool

Proper maintenance practices

To minimise the need for pool drainage, implementing proper maintenance practices is essential. Regular cleaning and monitoring of chemical balance can help prevent the accumulation of debris and algae, reducing the likelihood of drainage requirements. Additionally, proactive measures such as inspecting and repairing leaks promptly can preserve the integrity of the pool structure, eliminating the need for drastic measures like emptying the pool.

Professional assistance

When faced with issues that may seem to warrant pool drainage, seeking professional assistance is advisable. Pool specialists possess the expertise to assess the situation accurately and recommend appropriate solutions. From addressing structural concerns to implementing alternative drainage methods, consulting with professionals can help pool owners navigate challenges effectively. By leveraging expert guidance, pool owners can avoid the pitfalls associated with emptying their swimming pools unnecessarily.

When It’s Okay to Empty Your Pool

The only time it would be a good idea to empty your pool would be when performing an acid wash or resurfacing. An acid wash involves draining the pool to apply an acid wash solution to remove stains and discoloration. Resurfacing is having a new pebblecrete, vinyl liner etc laid; however, even in these scenarios, it’s crucial to take precautions to prevent structural damage and ensure the safety of your pool. “Always consult with a professional before undertaking any major maintenance task to avoid costly mistakes” Will advises.

Think Again Before Emptying Your Pool.

Emptying a swimming pool should not be taken lightly, as it can have far-reaching consequences for both the pool and the surrounding environment. Understanding the structural, environmental, and financial implications of pool drainage underscores the importance of exploring alternative solutions whenever possible. By adopting proper maintenance practices and seeking professional assistance when needed, pool owners can ensure the longevity and sustainability of their pools while minimising negative impacts on the environment.
