Lawrence Indoor Aquatic Center soon will close for nearly a month while city crews perform maintenance work.

The pool, 4706 Overland Drive, will close Sunday and not reopen until Aug. 21. Crews will rebuild pool pumps, work on heating and ventilation systems, repaint, and do general cleaning.

When the center reopens in late August, it also will begin its fall hours. The new hours for the center will be 5:15 a.m. to 7:45 p.m. Monday through Friday, 9 a.m. to 7:45 p.m. on Saturdays and 1 p.m. to 5:45 p.m. on Sundays.
