Spring flush

The Glengarry News - - The Opinion Page -

De­liv­er­ing high qual­ity drink­ing wa­ter to res­i­dents re­mains a pri­or­ity for the Town­ship of North Glen­garry, the mu­nic­i­pal­ity says.

“This means that we need to carry out a va­ri­ety of main­te­nance jobs de­signed to keep our wa­ter works sys­tem in top shape. Reg­u­lar main­te­nance also helps us to iden­tify any prob­lems that might need to be re­solved dur­ing our Sum­mer con­struc­tion projects,” the town­ship says in a press re­lease.”

One of these jobs is to pe­ri­od­i­cally flush some wa­ter mains, par­tic­u­larly if nat­u­ral sed­i­ments have built up in pipes.

The waterworks De­part­ment has com­menced a com­pre­hen­sive flush of the wa­ter mains in Alexan­dria and Glen Robertson. Crews will be­gin by flush­ing the wa­ter near the Alexan­dria wa­ter treat­ment plant, at 22 Gernish St.

“We al­ways start from where the wa­ter is clean­est and we push the wa­ter out­wards. We are flush­ing out the sys­tem. Our team will be work­ing in a very sys­tem­atic or­der to get this done as quickly as pos­si­ble,” said waterworks man­ager Dean McDon­ald.

Flush­ing of the wa­ter sys­tem is ex­pected to take be­tween four and six weeks to com­plete. A crew of two wa­ter spe­cial­ists will be tasked with per­form­ing main­te­nance on more than 140 hy­drants and close to 500 wa­ter valves.

Dur­ing this process, res­i­dents can ex­pect to see wa­ter run­ning down af­fected streets. There may also be pe­ri­odic dips in wa­ter pres­sure. In some cases, af­fected home­own­ers may find that their tap wa­ter is cloudy, or yel­low in colour.

If your wa­ter clar­ity is af­fected, you are ad­vised to turn on all of the taps in your res­i­dence and to al­low your wa­ter to run for five to ten min­utes. This will help to re­move the sed­i­ment from your pipes. If after 20 min­utes you do not see an im­prove­ment in your wa­ter clar­ity, no­tify the waterworks de­part­ment.

A new multi-pur­pose unit was pur­chased in 2015 to in­crease the ef­fi­ciency of valve main­te­nance and re­place­ment. This unit in­cludes a ma­chine that is cal­i­brated to op­er­ate and turn the wa­ter valves. It is ca­pa­ble of count­ing the turns, and mea­sur­ing the torque on each in­di­vid­ual valve. This cuts down on dam­age to the valves and it saves on the over­all cost of sea­sonal main­te­nance.

In ad­di­tion to im­prov­ing the qual­ity of the wa­ter by flush­ing out sed­i­ments, the bi- an­nual flush­ing of the sys­tem helps to iden­tify which valves and hy­drants need to be re­placed, due to age or dam­age. The town­ship in­vests ap­prox­i­mately $30,000 in up­grad­ing these sys­tems each year. The sys­tem is flushed at least twice each year, in Spring and Fall. How will you be af­fected? Your tap wa­ter will be safe to drink, but dur­ing the flush­ing process tak­ing place in your area, your wa­ter may be­come cloudy or dis­coloured, your wa­ter sup­ply may be in­ter­rupted for short pe­ri­ods of time or you may ex­pe­ri­ence lower than nor­mal wa­ter pres­sure.

Con­tact the waterworks de­part­ment (613-525-3087) if your wa­ter re­mains dis­coloured after run­ning your taps for more than 20 min­utes.

Sys­tem cleanouts are meant to en­sure high qual­ity of wa­ter is main­tained
