What Do I Do to My Swimming Pool After a Flood?

As Alexander Graham Bell said, “Preparation is the key to success.” So, to help you be prepared to handle a flooded pool should the need ever arise, we’ve put together a list of the key issues you might encounter in that situation, and how to manage them.

Electrical Dangers

One of the biggest dangers when flooding occurs is from electrical hazards. In fact, according to the Association of Pool and Spa Professionals®, electrocution is responsible for many deaths after a storm. Your very first step, before even evaluating what clean up efforts will be required, is to disconnect the power to your pool at the circuit breaker. This includes the power to all pool and spa equipment, outdoor outlets, lighting fixtures, and appliances. Ensure you don’t touch the circuit breaker with wet hands or while standing in water. For safety, use a plastic or rubber tool to flip the switch, and use only one hand. If the fuse box is damaged, contact an electrician to inspect it before you handle it.

Even if wires and electrical equipment have dried out, they still present a fire hazard. You can anticipate that you’ll need to have all electrical components replaced by a professional electrician.

Contaminated Water

If flooding occurs, you’ll almost certainly see murky or cloudy water in your pool; however, even if it appears pretty clear, don’t use the water or let your pets swim in it. A catastrophic flood will contaminate your water with hazardous chemicals like fertilizer, and other dangerous contaminants like sewage. While the water can be rehabilitated in some instances of flooding, in the case of storm surge or catastrophic flooding, the water can’t be salvaged. It will need to be drained, the pool and all hardscaping cleaned, and the plumbing lines purged before the pool can be refilled.

It is important the contaminated pool water is disposed of according to the guidelines of local water and sewage regulations. Additionally, if groundwater levels are high, it isn’t safe to drain your pool. Believe it or not, doing so in that case can cause an inground pool to “pop” out of place and cause major structural damage. If you have any questions about whether it’s safe to drain your pool, contact us to verify or to let us handle draining the pool for you.


For our Florida friends, a flood can mean discovering alligators and poisonous snakes enjoying your pool when you return. Which, makes it good to live in Connecticut! While we don’t have to worry about alligators, mosquitoes love stagnant water and not only are the little buzzers annoying, they can carry infectious diseases. So, the sooner you can deal with a flooded pool and rid it of mosquitoes the better. If you’re unable to rehabilitate the pool immediately, you can use a larvicide or pesticide in the water, which would then make it a requirement to drain the pool completely.
