Safeguarding the environment with technology and training
In celebration of International Women in Engineering Day on June 23, we are sharing how our women engineers #MakeSafetySeen by demonstrating strong safety principles in their work and committing to deliver a safer world through their engineering expertise.

As chief resident engineer from our Water business line in Hong Kong, Cherry Yau shares one of her most impactful Water projects: the transformation of a traditional sewage treatment plant into a safe and green ecological campus for all.
The project started end of 2019 and involved upgrading the capacity and treatment levels of an existing Shek Wu Hui Sewage Treatment Plant to become Shek Wu Hui Effluent Polishing Plant (SWHEPP), for which we continue to provide design, project management and construction supervision services. Our primary goal for the project in conjunction with our client, the Drainage Services Department (DSD) of Hong Kong SAR, is to deliver the facility in a safe, cost-effective and collaborative manner while building strong relationships with different stakeholders and the surrounding local communities. Upon completion, SWHEPP will become the largest tertiary sewage treatment plant in Hong Kong and will meet the needs of the new development areas in the region.
I am the chief resident engineer for the project and lead a team of 130 staff overseeing four construction contracts. Given the multidisciplinary nature of the project, I’m also involved in the implementation of digital technologies such as Blockchain, BIM, CDE and electronic site supervision systems. Safeguard is one of our core values at AECOM. Due to the nature of the project and the potential hazards involved, safety is of paramount importance, especially when it comes to protecting the workers on-site.
The construction of SWHEPP is a complex project that involves various risky construction activities such as deep excavation, construction of large reinforced concrete tanks in special shape, working within running sewage, and installation of hefty mechanical and electrical systems. Safety measures are in place to prevent accidents and injuries and minimize various risks such as confined space, work at heights, heavy lifting and electrical hazards.
Together with the project team, we have implemented a comprehensive safety program that includes training on safety protocols, providing appropriate personal protective equipment, deriving alternative construction method to avoid risky construction operations, conducting regular safety inspections, and promoting a culture of safety on the job site.
These safety measures have ensured that the project is completed with minimal incidents. They’ve also received wide acclaim. SWHEPP has won the Best Construction Sites Safety and Housekeeping Award (E&M Works Contracts Category) from DSD’s Construction Sites Safety and Housekeeping Award Scheme 2021, and Merits in 27th and 28th Considerate Contractors Site Award Scheme by the Development Bureau.
Additionally, the project team conglomerated a unified BIM execution plan covering the four contracts under this project and adopts BIM360 as a Common Data Environment (CDE) to serve as the project’s centralized design information and data exchange platform. The CDE allows each discipline and each interfacing contractors to gather synchronized information with up-to-date models, based on which project team members can carry out cross discipline discussions to identify interface issues which require coordination, as well as to visualize construction methodologies and future operation modes with animations to identify potential safety concerns prior to implementation.
With advanced technologies such as the Membrane Bioreactor, the plant will be able to treat effluents efficiently and meets the tertiary standards to avoid extra pollution to the nearby Deep Bay which has high ecological value for the neighboring community. Through improved water quality in the area, the project will create a positive impact on the general public and will help preserve the local marine environment.
We were also able to increase the treatment capacity of the plant two-fold within its existing footprint. This upgrade allows the plant to treat more sewage and meet the needs of a growing population in the New Territories. The project ensures that there is sufficient capacity to treat sewage, reducing the pollutants and improving the overall quality of life for the local community.
This project was selected as Winner of Water Project (2021), Winner of Contract Innovation (2022), and Runner-up of Consultant (2023) of the Year under the Martin Barnes Awards, which recognizes excellence in project delivery and showcase examples of good practice through collaboration from across the world.
