A major leak in Whitehorse's sewage system was repaired mid last week, but the extent of the procedure's environmental impacts are still unknown. The Marwell Lift Station, which acts as a conduit for the majority of the city's wastewater and sewage, was recently closed for a week to allow crews to investigate and fix the leaking pipe. During that time, the city opted to temporarily include bypass valves to dump a large volume of raw sewage into the Yukon River.
