Wa­ter sys­tem clean-out

The Glengarry News - - News -

If you see wa­ter run­ning down your street over the next few weeks, rest as­sured that it is merely a sign that North Glen­garry is con­duct­ing a cleanup.

“De­liv­er­ing high qual­ity drink­ing wa­ter to our res­i­dents re­mains a pri­or­ity for the Town­ship of North Glen­garry. This means that we need to carry out a va­ri­ety of main­te­nance jobs de­signed to keep our wa­ter works sys­tem in top shape,” the mu­nic­i­pal­ity says.

“Reg­u­lar main­te­nance also helps us to iden­tify any prob­lems that might need to be re­solved dur­ing our sum­mer con­struc­tion projects. One of th­ese jobs is to pe­ri­od­i­cally flush some of our wa­ter mains, par­tic­u­larly if we be­lieve that nat­u­ral sed­i­ments may have built up in­side of the pipes.”

The wa­ter­works de­part­ment has started a com­pre­hen­sive flush of wa­ter mains in Alexan­dria and Glen Robert­son. Crews be­gan by flush­ing wa­ter near the wa­ter treat­ment plant, at 22 Gernish St., Alexan­dria.

“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 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 at 613-525-3087.

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 which are flushed in the spring and fall.


SEA­SONAL OP­ER­A­TION: Flush­ing is part of reg­u­lar wa­ter­works main­te­nance.
