The paper plant’s management says that, while it is willing to collect the data requested, the new focus report could jeopardize its ability to meet the government’s timeline to complete construction of a new waste management facility by January 31, 2020. The government passed the Boat Harbour Act in 2015, launching a five-year countdown to the closure of the mill's current treatment site.
SASKATCHEWAN GETTING WATER, WASTEWATER AND FLOOD RESILIENCY FUNDING
The government of Saskatchewans recently announced funding for upgrades to Meadow Lake's water and wastewater management systems. Due to geography and climate change, Infrastructure Canada said residents on the east side of Meadow Lake face increasingly serious flooding issues. Especially during spring thaws, large volumes of stormwater create a high risk of ruptures in the 50-year old sewer pipes that run alongside drinking water mains. This can leak contaminated water into the drinking water system. Under this project, all of the community’s common trench sewer and water pipes will be replaced. The city will also relocate its existing sewage lagoon to outside the city limits to protect Backwater Creek, which sits behind the existing lagoon, from raw sewage overflows. Backwater Creek runs into Meadow Lake, which is the raw water source for the city’s drinking water treatment plant. Ralph Goodale, federal Minister of Public Safety and Emergency Preparedness, has announced funding for eight new water and wastewater projects in Saskatchewan.
