Water work in Lennoxville
Since the end of June, the Borough of Lennoxville has been having trouble meeting the daily potable water needs of its citizens. At the beginning of August, the City of Sherbrooke temporarily connected the Lennoxville water supply to the City’s main water supply to try to improve the situation.
An inhibiting, food-grade product had to be added to this new water supply system to prevent discolouration when the Lennoxville water, which contains iron, mixes with the chlorinated water from Sherbrooke. Work will be done in the fall to permanently connect the two systems.
More preparatory work will be done on Bowen South this week on a portion of the JM Jeanson aqueduct network. This work aims to replace a water pipe that is too small to provide enough water to the St. Francis sector in anticipation of the work to be done in the fall.
Once this work is completed, well no. 3 in Lennoxville will be shut because of its low capacity and its high mineral content, including iron and manganese which can discolour chlorinated water. To this effect, the City will begin injecting a solution of polyphosphate into the two other wells in operation. Despite these measures, a little discolouration of the water may still occur.
Furthermore, during the week of August 15th, the St. Francis sector will gradually be fed from the JM Jeanson network by the temporary installations. This will reduce the demand for potable water from the other two underground wells that serve the Borough’s population, not including the St. Francis sector. The water consumption of citizens in the Lennoxville Borough is, on average, 3,500 cubic metres of water per day, which is just equal to the amount the wells can produce. The City’s water experts expect consumption to increase to about 4,500 cubic metres a day in the next few weeks, especially at the beginning of September with the return to school.
