Sherwood Park's Millennium Place pool and amenities are shut down for annual maintenance.
"There's a lot to do with the maintenance of all the pools mechanical systems, like the filtration system, boilers and all the other stuff that makes the pool tick," said Ben Gibas, the facility supervisor at Millennium Place.
Some of the other work going on includes light replacements, tile repair work and a thorough pool cleaning that covers the hallways, sauna, change rooms and steam room.
The pool will be reopened at regular hours on September 24.
