An engineering report on replacing an aging Dartmouth culvert appears to challenge claims by Halifax Water and the municipality that unearthing the buried Sawmill River is too costly and complicated. The CBCL Ltd. report, obtained by The Chronicle Herald under a freedom of information request, examines options for replacing a half-kilometre long storm sewer that runs from Sullivans Pond to Dartmouth Cove. The 2.7-metre corrugated steel pipe was installed in the 1970s to bury the Sawmill River, the watershed of four Dartmouth lakes, after torrential rains caused the river to breach its banks and flood a large swath of the city. With the rusting underground tunnel in need of replacement, calls for “daylighting” the river — uncovering the underground river — have grown louder.
