Murrumbidgee Local Health District senior environmental officer, Tony Burns, said if pools weren't maintained properly they could become a source of infection.

"As the weather heats up so does the opportunity for bugs and infections to grow at a rapid rate," Mr Burns said.

"Swimming pools provide the perfect environment for this to happen so it's important to be vigilant in keeping the pool sparkling clean and healthy.  Diseases such as cryptosporidiosis are highly contagious and are easily spread simply by swallowing contaminated pool water.

"Many bacteria can be killed simply by using chlorine and through normal pool filtration. However, diseases such as Giardia and cryptosporidium are not eliminated so easily. Therefore we encourage people to take care not to introduce these bugs to the pool in the first place," Mr Burns said.

Here are some summer pool tips to keep you healthy:

- Clean pool and filter regularly

- Operate your pool filter between 8 and 12 hours per day depending on pool use

- Don't allow pets in the pool.

- Stay out of the pool if you have been feeling unwell

- If you have experienced gastroenteritis, wait until you have been symptom free for at least one week before returning to the pool

- Avoid swallowing pool water

- Use disposable swimming nappies for infants

- Avoid swimmers itch by keeping pools below 26 degrees and well disinfected (chlorinated)

- Keep pool gates closed and make sure a resuscitation chart is clearly displayed nearby.

- Avoid using a heated spa bath after consuming alcohol. Alcohol causes blood vessels dilate and venous pooling can occur resulting in fainting and possible drowning.
