Definition of a Public Pool, Spa, or Spray Grounds
If you run or own a public pool, Environmental Health Services helps make sure it's safe and healthy.
This page applies to operators and owners of public pools, spas, and spray grounds.
What is a public pool?
Any swimming pool, spa, or spray ground open to the general public — whether it’s free or not — is considered “public.”
What's a spray ground?
It's an outdoor play area designed for children that features water sprays and fountains.
The Environmental Health Division regulates all public pools and similar facilities. We perform inspections and make sure that new or renovated pools, spas, and spray parks are constructed safely.
Environmental Health Services does not regulate private pools or spas at a single-family residence.
