Did you know that all storm drains in Southlake drain directly into a pond, lake, creek or river? Inappropriate discharge could affect wetlands, wildlife and our community, which is why proper discharge is important. When draining your pool, it’s best to take safety measures to aid proper drainage and help the environment. Before you start the process, make sure you use a pool test kit and ensure the water is free of algaecides, the pH falls between 6 and 8 and that the pool is free of chlorine. Avoid draining your pool if you have recently treated your lawn with pesticides or fertilizers.
