Results of an investigation into the scandal involving the procurement of bottled water for certain government offices are "expected to be ready next month", authorities announced on Tuesday.

The Financial Services and the Treasury Bureau, which set up a task force to look into the incident, said both the review on the existing government procurement regime and a disciplinary investigation have concluded.

"The government is studying the investigation report and consulting the Department of Justice to determine suitable disciplinary actions to be taken," the bureau's statement said.

"Relevant results will be announced as soon as possible and are expected to be ready next month. The results will then be announced together with the task force report to conclude the incident."

The bureau also said the Government Logistics Department, which was at the centre of the incident, followed new guidelines issued in October as it launched an open tender for a contract on supplying bottled drinking water to government offices on Hong Kong Island and some outlying islands.

"This tender exercise has strengthened relevant requirements at various stages, including preparation of tender documents, tender evaluation and contract management, to help procurement officers guard against fraudulent acts more effectively and to select a supplier competent to ensure a stable supply of bottled drinking water in accordance with contract terms," the statement said.

The incident came to light in August, when Xin Ding Xin -- a company that was awarded a HK$52 million contract to provide bottled drinking water to certain government offices -- was accused of lying about how it sourced the water from the mainland.

A company director has been charged with fraud for allegedly providing false documents to win the water contract.
