Boil Water Advisory lifted

The precautionary Boil Water Advisory that went into effect for the communities of Silverado, Belmont and Yorkville has been fully lifted by Alberta Health Services. The advisory for the community of Silverado was lifted on June 3, with the remaining communities of Belmont and Yorkville lifted on June 4.

This follows testing that confirmed that water in the three communities meets all water quality guidelines and standards and is safe for normal consumption.

What to do after a boil water advisory ends

Residents of, businesses in and visitors to Silverado, Belmont and Yorkville can resume normal consumption of water, following the completion of these important steps:

·         Household faucets: Turn on all taps and flush water lines for at least 20 minutes. Wash tap aerators and screens in hot soapy water then disinfect them for ten minutes in a solution of one part bleach to nine parts water.  

·         Refrigerators with water and ice dispensers, water coolers, filters and automatic ice makers: Read and follow the manufacturer’s instructions for flushing, cleaning, and sanitizing. Run water for five minutes before using the water.

·         Hot water tank: Drain and refill hot-water tanks that are set below 45ºC (normal setting is 60ºC).

·         Water softener: Run water softeners through a regeneration cycle. Follow the instructions from the manufacturer.

The City of Calgary thanks affected residents and businesses for their patience and cooperation during this time.
