La Pinière Water Treatment Plant
That wastewater treatment plant is located on the La Pinière boulevard, in Terrebonne, north east of Montréal. It was built in 1994 and serves 58,121 citizens. Over the last 20 years, the City has noticed a high growth in its population, and the La Pinière water treatment had to be modified to treat wastewater of 49,600 new citizens, and an industrial park.
In 2014, the City received a report from the Beaudoin Hurens engineering firm, presenting five water treatment solutions for the upgrading of the actual water treatment plan with regard to its maximal population, charges and upcoming standards. Of those five scenarios, three were feasible.
That feasibility study was accepted by the city’s executive committee, who recommended to have to modify the wastewater plant by implementing an activated sludge reactor, with extended aeration.
The project was put to an halt in February 2016, due to its high costs. In June 2016, SMi engineering firm presented another study with five scenarios, and a scenario for a distinct plant of 5000 units only. The City mandated AXOR engineering for the design, drawings and specifications and project’s surveillance. The project is at the design phase, 30%.
