Important information regarding the discharge of pool water, hot tubs and spas:
Water from pools, hot tubs and spas is filled with chemicals such as chlorine/bromine, salt, copper-based algaecides and more. These chemicals are harmful to the fish and organisms that live in water systems.

Depending on local municipalities, owners of pools, hot tubs and spas might need to lower chlorine/bromine levels prior to releasing water into the storm sewer system. Since these chemicals dissipate on their own, leaving the pool uncovered for two weeks is usually enough time to reduce the levels. A neutralizer can also be used to reduce the levels of chlorine/bromine to an acceptable level.

The water from salt water pools has high levels of chlorides might need to discharge into the sanitary as it cannot be discharge into the storm sewer system in some places.

Check with local municipalities to find out what types of bylaws are in effect when closing pools, spas and hot tubs.
