Application of “Single Site, Multiple Use” in a sewerage project - a breakthrough trial in Kwun Tong Sewage Pumping Station

Abstract

Hong Kong’s land resources are undoubtedly precious. At the same time, sewerage facilities are of paramount importance to ensure public hygiene and preserve the receiving water quality. Due to the limited land resources, it is inevitable to locate these facilities in close proximity to residential areas. Consequently, objections from neighbouring residents, stemming from the “Not-In-My-Backyard” effect, are frequently received as there are concerns regarding the potential impacts in respect of visual pleasantness and odours. To address this challenge, a breakthrough project, Enhancement Works for Kwun Tong Sewage Pumping Station, was implemented, applying an innovative design strategy, known as the “Single Site, Multiple Use” concept. This project involved constructing a landscaped deck to cover the sewerage facilities, effectively reducing the visual and odour impacts in the surrounding area. Data forecasting and analysis techniques were used to design the capacity of the Balancing Tank. This project not only enhanced the appearance of the otherwise dull sewerage infrastructure, but also improved the quality of life for local residents, as evidenced by the overwhelmingly positive feedback. The successful implementation of this project inspires engineers to build better infrastructure, and provides valuable insights for future sewerage projects aiming to balance the environmental, social, and spatial considerations in compact cities.
