The pool at the Robert Hartley Sports Complex in Hawkesbury will be closed all summer for major work estimated at $3.5 million. The renovations will focus on the roof, corroded joists and dehumidifiers. Work should begin at the end of June, in order to meet the commitments to the Orca Swim Club. A comprehensive assessment of the complex, built in 1979, will also be conducted to plan further future renovations.
