Never discharge pool or spa water to a street, alley, or stormdrain.
When emptying a pool or spa, let chlorine dissipate for 5 to 7 days. Then recycle the water by gradually draining it onto a landscaped area.
Chlorinated water may be discharged into the sanitary sewer system by running a hose to a utility sink or to a sewer pipe cleanout junction.
DO NOT use copper-based algaecides. Control algae with chlorine or other alternatives to copper-based chemicals. Copper is harmful to aquatic life and cannot be completely removed by the sewage treatment plant.
