About Public Pools

A public pool means any swimming pool, spa, spray ground, or special purpose pool operated for the use of the general public with or without charge, or for the use of the members and guests of a private club, including any swimming pool located on the grounds of a hotel, motel, inn, an apartment complex, or any residential setting other than a single-family home.

Public health protections can help prevent illnesses, accidents, and drownings. Properly maintained and regulated public pools greatly minimize these risks.

There are many diseases that can be transmitted in pool water, especially if they are not properly maintained. People can carry bacteria, viruses and parasites within their bodies and on their skin.  Some of these organisms can be released into the pool water to infect other swimmers. Organisms may enter the body through the mouth, nose, ears, and eyes.
