The Town of Newmarket is asking some residents to not use their water for certain days between now and Aug. 16.

The town is conducting its annual water main cleaning program from 10 p.m. to 6 a.m. in Wards 2, 3 and 5.

York Region.com reports the water mains will be cleaned via swabbing — a process considered one of the most effective water distribution system maintenance procedures. It is completed by cleaning several of the water mains that, over time, have built up sediment. The annual procedure helps reduce the effects of water degradation.

A foam sponge, or ‘swab,’ will be inserted into the water main through a fire hydrant. The swab is slightly larger than the diameter of the water main, and as it is pushed through with water pressure, it will clear any sediment and push it up and out another fire hydrant.

Before the scheduled water main cleaning, residents are being asked to:

• Fill a large, clean container with tap water for drinking and cooking — it’s best to store it in the fridge;

• Complete all dishwashing, clothes washing and other water-use activities;

• Fill their bathtub with water for use around the house, including flushing the toilet; and

• Turn off their water valve, located next to the water meter to prevent water use.

Residents who have a medical condition requiring treatment with constant water service should contact the town immediately at 905-895-5193.

During the scheduled water main cleaning operation, residents should avoid using water for any purpose. The operation is expected to take approximately eight to 10 hours to complete.

Afterwards, residents may notice discolouration in their water due to the sediment that was swabbed and flushed from the water mains; run a cold water tap until the water is clear.

Affected households will be notified at least 48 hours in advance with door hangers. Businesses will be notified at least 72 hours in advance through a hand-delivered letter. Information will also be provided on what to do before, during and after the water main cleaning program is complete for their area and the scheduled time and date.
