A precautionary boil water advisory was issued late Friday morning for the Clearview Ridge and Garden Heights subdivisions in Red Deer.

The city has opened a call centre for anyone who has questions about the advisory. It will be open until 9 p.m. Friday and the number is 403-342-8750.

About 600 homes and multi-family complexes have been asked to boil their water until further notice after water flow and pressure were disrupted at about 9:15 a.m. by construction in the Timberlands area.

Water flow and pressure was restored after 45 minutes but the boil water advisory was issued as a precautionary measure after the pressure in the system decreased. The boil water advisory will be lifted when suitable flushing has taken place, and the City of Red Deer confirms there is no contamination.

Areas affected by the boil water advisory include both residential and commercial areas in Garden Heights and Clearview Ridge.

City staff are going door-to-door to all affected homes to advise of the situation and provide an information package from the city and Alberta Health Services.
