A new sewage system at the Sun Tin Covid-19 community isolation facility was built in just seven days, far shorter than the usual month such projects take, Hong Kong’s secretary for development has revealed.

Michael Wong Wai-lun said on his blog on Sunday that work on a sewage pump station and a 1.8km-long rising main was completed. Waste water would be sent to the sewage treatment facility at nearby Lok Ma Chau Control Point.

“Building the system is full of challenges, it requires a lot of manpower, preparation in materials, refining the location and design of the pumping station,” he said.

About 200 workers from three contractors were mobilised. Construction was carried out for 24 hours a day, shortening the duration of the project from a month to just seven days, Mic Ng Ting-hong, an engineer at the Drainage Services Department, revealed.

Workers even volunteered to shorten their dinner breaks on one night to finish a concreting process.

Ng said planning the route of the pipeline was one of the major challenges as its original path crossed beneath a main road, which would require road closures and digging, as well as resurfacing, but the team found an alternative to save time.
