Wa­ter work in Len­noxville

Stanstead Journal - - NEWS - Vic­to­ria Vanier

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.
