Expansion of Sha Tau Kok Sewage Treatment Works Phase 1

Expansion of Sha Tau Kok Sewage Treatment Works Phase 1

The Sha Tau Kok Sewage Treatment Works Phase 1 Expansion project stands as a testament to Hong Kong’s commitment to environmental sustainability and efficient wastewater management. It aims to increase the treatment capacity, ensuring that the city’s sewage is processed efficiently and in an environmentally responsible manner. A remarkable feature of this expansion is the use of Groutec S couplers to seamlessly link precast columns of the building.

Groutec is designed for the efficient and easy installation of precast concrete elements, reducing construction time and labor costs while providing full structural connection. For this project, Groutec S diameter 32mm precast couplers have been used to connect precast columns in vertical applications. The Groutec coupler is installed in the bottom element, and then grout is poured by gravity directly into the coupler cavity. This process ensures the structural integrity and longevity of the facility.
