Hydrant Flushing

Jacobs (OMI) will carry out hydrant flushing from mid-May through September. Residents may experience temporary low water pressure and/or cloudy but harmless discolouration of the water. Should discolouration occur, running a cold water tap for a short period will typically restore water conditions to normal.  Where practical, residents should avoid washing laundry during operational hours as to do so could result in discolouration of clothing.

Payment Options

We have many options for paying your water bills.

Water Meters

All homes and businesses are equipped with a water meter. Depending on the model of the water meter, it is read by an electronic reader or a remote on the outside of your home. You can confirm the reading on your meter by following these instructions to read your water meter.
