Updated at 7.12pm: An underground fresh water pipe at Wellington Street in Central burst on Thursday morning affecting over 100 restaurants, local news media reported on Friday. Towngas started replacing a gas pipe two days ago at Wellington Street. The construction continued on Thursday at 9am. A worker broke a water pipe, 10 centimetres in diameter, when he attempted to dig a tunnel, Apple Daily reported. Water four-storeys high was gushing from the pipe. There was subsequently no water in Wellington Street and Lan Kwai Fong. The leakage also weakened water pressure in D'Aguilar Street and Wo On Lane. The Water Supplies Department first switched off the water pipe. It then opened two public standpipes and dispatched two water trucks at 11.30am to supply water temporarily, the Oriental Daily reported. Some restaurants had to get water from restaurants on other streets. Others, like Yung Kee Restaurant, still operated normally because they had preserved fresh water in a tank. Water supplies resumed at 1.30pm after four hours of repairs. Some restaurants complained the water truck arrived late and the Water Supplies Department's reaction had been slow, Ming Pao Daily reported. The Lan Kwai Fong Association said over 100 restaurants in Lan Kwai Fong were affected by the leakage. The tenants plan to meet to discuss whether they will try to claim compensation. Kam Nai Wai, Central and Western district councilor, said the worker should have known the location of water pipes beforehand. He said that there was a fresh water pipe next to the broken pipe.
