The company that supplies water to northern China's Shijiazhuang City, capital of Hebei Province, on Wednesday apologized for disrupted services in the city.

While issuing a statement to apologize for the inconvenience to citizens of the city, the company said last week's flood washed mud and sand into a reservoir, leading to a disruption of its regular production.

The incident has caused a water shortage and the company has made an emergency switch to using Yangtze River water, but the supply has not fully resumed.
