Wong added that the team also submits annual reports to its holding company, Suez, to ensure the BCP is updated and implemented as planned.

These plans help Macao Water to better cope with emergency and better comply with Suez's BCP guidelines, said Lam. Suez released guideline 18 months ago detailing five different levels of BCP strategy. With the recent plans and implementations, Macao Water is now close to Level Two, Lam added.

'The strategy is based on ISO 17799,' he said. 'It's quite a complicated and demanding strategy, which covers policies, IT infrastructure and physical infrastructure.'
