Our water distribution system is designed and operated to deliver a minimum acceptable pressure delivered to each Lethbridge service connection of no less than 300 kilopascals (45 psi) during peak hour demand, and 350 kilopascals (50 psi) at maximum day demand. The maximum pressure should not exceed 625 kilopascals (90 psi).
If there is a water main flush in your area, the water pressure will seem low, but will return to normal once the water main flushing is complete.
If there is another reason, contact 311 (403-320-3111) and they will assist you in finding out the cause.

This occurs most often during the winter months. Water can entrap tiny air bubbles, particularly if the water is extremely cold, or if it passes through a tiny screen, like those found in some faucets. As oxygen is a gas, it dissipates with time and the water clears up.
Yes. It is added as a dental health measure to prevent tooth decay. Its application is authorized under City Bylaw 3236 and has been added to the water in Lethbridge since 1974. The dosage of fluoride added to the water is 0.5mg/L to 0.7mg/L. The resulting concentration of fluoride in the treated water is 0.7mg/L to 0.9mg/L. The use of this chemical is not necessary to produce potable water.
The water inside building’s plumbing that may have been just sitting there for an extended period of time, with little or no use, could have become stagnant. Prolonged building water stagnation can lead to low chlorine levels, colour, or taste and odour issues inside your building. It could also result in elevated lead, copper, and Legionella levels at the tap. If your building has been empty for more than two or three weeks, the plumbing should be flushed to each fixture to provide them with fresh water from the water distribution system.
