As the end of swimming season approaches, residents in Prince William County are being reminded to follow proper procedures when draining their pools. The county has issued guidance to prevent environmental harm and ensure compliance with stormwater regulations.
Pool water can contain chemicals such as chlorine, algaecides, and salts. If this water is released directly into storm drains, it flows untreated into local streams, rivers, and ultimately the Chesapeake Bay. Even small amounts of these chemicals can be harmful to aquatic life.
The county recommends several steps for safe pool draining. Residents should stop adding chlorine or other sanitizers at least ten days before draining and test the water to confirm that chlorine levels are at zero. Draining should be done slowly over grass or landscaped areas so that the water is absorbed by the ground and filtered naturally. Direct discharge into storm drains, ditches, or streets should be avoided because these channels lead straight to streams without any treatment. For saltwater pools, the water should be drained into the sanitary sewer system rather than onto the ground or into storm drains.
“By taking a few extra steps, you can help protect Prince William County’s waterways, wildlife, and overall water quality. Proper pool draining is not just good practice, it’s part of being a responsible neighbor and environmental steward.”
Residents who witness improper pool draining or suspect an illicit discharge are encouraged to contact the Environmental Management Division by email at [email protected] or by calling 703-792-7070.
