Behind the scenes work continues in advance of construction of a new Lake Huron intake pipeline to the Petrolia Water Treatment Plant in Bright's Grove.
CIMA Canada Project Manager Adam Moore told Petrolia council, at a recent meeting, they're still working to obtain some permits and approvals.
"We are in the process of handling some comments from the various ministries involved," said Moore. "We have issued our notice of completion for the environmental assessment, the enabling studies have been completed, we just have a couple outstanding comments from the ministries to handle to satisfy our consultation requirements."
He said the new intake will extend 400 meters into the lake from the shoreline.
"This will run parallel to the existing intake. Concrete pressure pipe, HTP (hose pipe), are a couple of the options we're looking at for the new intake and it will be serviced as well from an onshore low-lift pump station," Moore said.
He said they're in the process of laying out the trajectory of the new intake and determining how it will be bridged into the new low-lift pump station.
"This is a below grade, concrete, submersible pump station. This will be located within the water treatment plant site. This will service incoming water from the intake and then pump that through our new pre-treatment system, ultimately into the water treatment plant," Moore said.
The new low-lift pump station is needed to keep the existing low-lift pump station and water treatment plant in service during construction.
It will include three duty pumps, one standby pump and have the capacity of 22 million litres per day.
Moore said they plan to submit the full detailed design for the intake contract this August and open the project for tenders in September.
It's hoped construction will start this October and finish by June 2025.
The original intake pipeline was installed in 1944.
