Policies
To ensure that all of our members can enjoy our facilities we ask that you understand and adhere to the following policies. Additionally, all members and their guests using the the pool do so at their own risk. Belmont Day and its personnel are not responsible for accident, injury, or loss or damage of personal property.
General policies for members and guests
- Members must check in upon arrival at the pool with the lifeguard on duty.

- Audio devices may only be used with earphones or played at low volume. Earphones may not be worn in the pool area.
- Members and guests under 16 years old must be accompanied at all times by a parent/guardian or nanny/babysitter.
Failure to follow these policies can result in a revocation of membership without a refund.
Our two pools are a wonderful way to cool off and enjoy the summer. We invite you to take a dip and beat the summer heat. To ensure everyone’s safety in the pools, we have the following policies regarding pool use.
