Hong Kong Systematically Expands Resource Recovery Capacity, Invests in Integrated Reuse Infrastructure

Jun 05, 2020

Hong Kong is improving resource efficiency, meeting resource recovery targets, while optimizing infrastructure lifecycle opportunities. The Drainage Services Department (DSD) of the Government of the Hong Kong Special Administrative Region has selected Black & Veatch to conduct a three-year investigation into upgrading the Tai Po Sewage Treatment Works (STW).

“Black & Veatch is committed to support our clients, like DSD, through infrastructure lifecycle opportunities. Black & Veatch specializes in the design of integrated wastewater treatment and resource recovery facilities. These facilities effectively achieve environmental protection goals through sustainable treatment, optimum biosolids use and economic value. Our professionals have worked on many advanced STW projects worldwide which required innovative approaches to overcome constraints that are similar to those in Tai Po STW,” says Andy Kwok, Managing Director, Black & Veatch Asia North.

One objective of the Tai Po STW upgrade is to increase the capacity of sewage treatment, biosolids management, energy recovery and sewage discharge disposal to support the housing and economic needs of the Tai Po District.

Another objective is to provide facilities to receive and digest sludge from the sewage treatment works in eastern New Territories for co-digestion with pre-treated food waste. Featuring a compact design, the upgraded STW is anticipated to accommodate the new regional sludge treatment facilities and future expansion.

Black & Veatch is tasked to provide review, site investigation, impact assessments and preliminary design for the upgrading of Tai Po STW. Core innovations that will be assessed for the Tai Po STW upgrade include:

  • Uncertainty-based dynamic process modelling, which enables the use of statistical techniques in combination with process models to evaluate solutions. It provides the ability to right-size process systems and equipment.

  • Low-energy solutions, for example biological nutrient removal incorporating sustainable nitrogen removal strategies.

  • High solids digestion, a compact solution that offers more effective management of high strength feedstocks.

Black & Veatch is a world leader in the design, construction, testing, start up, commissioning, and operation of advanced sewage treatment facilities. It is a pioneer in practical and economical water reclamation and reuse solutions for all types of water quality, with award-winning projects such as Singapore National Water Agency PUB’s Changi NEWater II plant.
