Water supply in Shijiazhuang, capital of north China's Hebei Province, has been disrupted after flooding was found to have contaminated the city's drinking water.

Shijiazhuang's water supply firm said on Friday that supply would be back to normal in about five days.

Torrential rain in Hebei since Wednesday morning has left 35 people dead and 77 missing, the provincial civil affairs department said on Friday. About 211,642 people have been evacuated over safety concerns.

The supply issue was caused by floods unsettling sediment in two reservoirs that supply water to six districts in Shijiazhuang.

The water company said it was limiting supply to industrial users, pumping out underground water and dispatching tankers to provide drinking water for residential use.

From Friday, water will be available to residents in three two-hour windows each day.

The city has been among the worst-hit in the province during the recent bad weather. Relief supplies including tents, quilts and clothing have been distributed to those in need.

Neighboring Shanxi Province has also been badly affected. The heavy rain has left seven people dead since Monday, according to the provincial civil affairs department.
