Water & Waste Management

The St. Clair River provides an abundant supply of cooling and process water for industrial users in the Sarnia Lambton Complex. Several brownfield and greenfield industrial opportunities exist on land that is serviced by existing cooling and process water infrastructure and capacity. For many of these industrial lands a Permit to Take Water (PTTW) is already in place. Many residences and businesses in Sarnia-Lambton are provided with potable water via the Lambton Area Water Supply System (LAWSS) which has a maximum rated capacity of 182,000 m3/day.

Many current chemical facilities operate their own wastewater treatment facilities. To accommodate new development, there are opportunities for process wastewater to be treated at the ARLANXEO biological wastewater treatment plant. The facility is a Ministry of the Environment, Conservation and Parks approved industrial wastewater facility, with a capacity of 24,000 m3/day.
