A precautionary boil water advisory has been lifted for parts of Moose Jaw, including the 15 Wing air force base, following a water main break.

The city issued the advisory for 15 Wing and the entire South Hill neighbourhood after crews responded to a water main break near a reservoir in the area Friday night.

Officials say city crews worked long hours through the weekend to fix the break.

The advisory was lifted Monday after water samples sent to the provincial lab tested negative for bacteria.
