Why Should You Clean Your Pool After A Flood Or Storm

A dirty swimming pool can be unsightly and unhealthy. It can also attract insects and disease-causing organisms.

If you have a swimming pool, clean it at least once every week. Here’s why you need to do this.

Murky Water

Swimming pools become cloudy after a flood or storm because of debris and dirt. These particles block sunlight and keep oxygen from reaching the water’s surface.

This creates murky water that makes swimming difficult for swimmers. Swimming in murky water puts people at risk of drowning.

Bacteria And Germs

Bacteria and viruses can enter your pool through cracks in the concrete. When the water becomes contaminated with bacteria and viruses, they can spread easily throughout the pool.

These germs can infect your skin and eyes. They can even cause serious illnesses, including pneumonia and meningitis.

Clogged Pool Filters

When water flows into your pool, it carries debris and dirt. This debris clogs up your pool filters.

The buildup of debris causes your pool filtration system to work harder. As a result, your pool will require more frequent cleaning.

Water-borne Infections and Illnesses

Flooded swimming pools often contain stagnant water. Stagnant water encourages the growth of harmful microorganisms like E. coli and Giardia.

These germs are dangerous if swallowed by humans. They can cause diarrhea, stomach cramps, vomiting, and other gastrointestinal problems.

Disease-Causing Organisms

Flooded swimming pool water can carry disease-causing organisms like Cryptosporidium, giardia, and Vibrio cholera.

Cryptosporidium is an intestinal parasite that can cause severe diarrhea. People who swim in infected water may develop symptoms such as nausea, abdominal pain, and diarrhea.

Giardia is another parasite that can cause illness. Symptoms include bloating, gas, diarrhea, fatigue, weight loss, and nausea.

Vibrio cholera is a bacterium that can cause severe diarrhea and dehydration.

Ineffective Pool Chemicals

You might think adding chemicals to your pool would help prevent algae growth. However, many chemicals used to treat swimming pools encourage algae growth.

Algae thrive when there is too much light, so these chemicals encourage algae growth.

Some of them can also harm fish and other aquatic life.

Tips to Keep Your Swimming Pool Clean

You may not need to do all these steps if you have a small backyard pool. However, you will want to take extra precautions if your pool is large.

Remember the following tips when cleaning your swimming pool after a flood or storm.

Clean the pool daily

Cleaning your pool once a week is usually enough. But if you notice mold growing around the pool’s edges, or if you see sediment at the bottom of the pool, you should clean it more often.

Make sure the pool’s filtration system is working properly

The most important part of keeping your pool clean is ensuring its filtration system works properly. If this component fails, you could end up with cloudy water, making it difficult for swimmers to enjoy their time in the pool.

Change the filters regularly.

Regularly changing the filters helps keep your pool clean and healthy. You should change them every three months.

Avoid leaving children unattended near the pool.

Children who play near pools without adult supervision are at risk of drowning.

Protect yourself against sunburn

Sunscreen lotions help protect your skin from the harmful effects of ultraviolet (UV) rays. Apply sunscreen 30 minutes before going into the pool.

Maintain a safe temperature

Keeping the water cool is an easy way to prevent scalding injuries. This also prevents bacteria growth.

Keep the pool covered during winter.

Covering the pool keeps it cooler than open-air pools. It also protects the pool from rain damage.

Use a cover over the pool.

A cover can protect your pool from debris such as leaves and twigs. It also helps keep the pool cleaner by preventing insects from building nests inside the pool.

Have fun!

Swim safely and enjoy your pool.
