Vacuum trucks are working non-stop to slurp water out of a sewer line after relentless rain caused sewer backups in more than 20 Griesbach-area homes.

Epcorpokeswoman Georgina De Cordova said on Saturday the company first received calls late Friday night of basements flooding in the north-central Edmonton neighbourhood.

Rain that fell in the area between Wednesday and Friday exceeded a sewer trunk line’s capacity, she said.

“The system is working. It’s just not able to keep up with the amount of volume that’s come through,” De Cordova said.

According to Environment Canada weather data online, a total of 78.7 millimetres of rain fell in Edmonton’s Blatchford area on Wednesday, Thursday and Friday. The largest deluge was on Thursday, when instruments measured 38.8 mm of precipitation.

Hydrovac trucks have been drawing water out of a Newson Road sewer line non-stop since Saturday morning, De Cordova said. Some of the homes with water in basements are near 153 Avenue and Castle Downs Road, she said.

She did not anticipate any other Edmonton neighbourhoods were at risk of similar floods.

De Cordova did not know how long it would take Epcor to clear the overtaxed sewer.

Epcor is advising property owners experiencing flooding to contact their insurance companies.
