Work is set to begin today on the North Sewer System upgrades just outside of Yorkton on Highway 9 North. Delays are to be expected, and detours will also be set up. While motorists are asked to be patient and slow down in the construction zone. Mayor Bob Maloney says these upgrades will improve the way rain water is handled during a storm. He also says the  project will take some time and there will be delays, but the time line depends on weather.
