Public Pools and Spas

Dedicated to the protection of public health and safety at public recreational facilities.

Pool regulations and codes are developed to make sure that treated recreational water facilities (for example, pools, hot tubs, and water parks) provide a clean, healthy, and safe environment for the public. These regulations set minimum standards (such as the amount of chlorine that should be in the pool) to decrease the public’s risk of illness and injury.

To ensure that these regulations are followed, the NHDES Pools and Spas Program regularly inspects treated recreational water venues. Private residential pools are exempt from this program. The state currently monitors conditions at more than 1,300 bathing facilities.

Standards of design have been established by NHDES to ensure that water quality is regularly sampled and analyzed, that construction designs provide for safe use, and that scheduled maintenance is regularly performed and recorded by the operator. If any of these standards are violated, a pool, spa or water slide may be closed by NHDES or the local health officer until corrective measures have been completed.

Safe and sanitary operating conditions at pools and spas can often be restored to acceptable standards by working with NHDES staff to make changes to the filtration or disinfection processes.

Legislative Changes for Public Pools and Spas

The NHDES Public Pool and Spa Program (RSA 485-A:26-27) was revised significantly by the state legislature in 2019 for the express purpose of increasing the public’s health and safety. At last count, the program has over 1,300 active public bathing facilities scattered across the state that are operated by towns, campgrounds, recreational camps, hotels and condominium complexes.

The revised program is designed to ensure that existing and future facilities are properly designed, constructed, operated and maintained by expanding the state’s ability to provide support to their owners and the public. Changes to the Public Pool and Spa Program will be part of a phased implementation, which is scheduled to occur from 2020 to 2022.

Major changes to the program include:

The approved training programs provided by Association of Pool and Spa Professionals and National Swimming Pool Foundation are available through a cooperative education group called the Pool and Hot Tub Alliance. This is a NEW requirement of the program.
