Public Swimming Pools

The Watertown Health Department is charged with the enforcement of the Massachusetts Swimming Pool Regulation, 105 CMR 435 (PDF). We routinely inspect and issue operating permits to all public and semi-public swimming pools.

New Swimming Pool Applications

If you wish to construct a public or semi-public swimming pool in Watertown, please submit plans and the Swimming Pool Plan Review Application to our department and the Watertown Building Department. Once the construction plan is approved and the building permit is issued, you may start construction of the pool.

Swimming Pool Permit Renewal

To renew a swimming pool permit the applicant must complete this Swimming Pool Permit Application (PDF) and submit the required documentation.


To file a complaint against a public or semi-public swimming pool, please contact the Health Department.
