Recognizing that green landscape enhances the quality of life, DSD has been conscious to apply greening effort to soften sewage treatment works, sewage and flood pumping facilities which could be visually sensitive in their neighbourhood. The greening helps reduce visual monotony, enrich local biodiversity and improve microclimate such as providing shades, absorbing heat and reducing flying dust. Trees and flowers also provide a sense of seasonal change and increase aesthetic quality.

Landscape treatment of the periphery could range from placing flower bed at the perimeter wall, allowing for a planting strip along the boundary to serve as a landscape buffer, to building a podium garden that is accessible by the public.

Landscaping within the sewage treatment works and sewage pumping stations elevates the ratio of green cover in the district. It also harmonises the shapes, textures and colours of such utility service architecture. Greenery mediates concrete buildings, tanks, pump rooms, exhaust pipes, walls, and opens area. Notable examples can be found in Stonecutters Island Sewage Treatment Works , Shatin Sewage Treatment Works  and Cyberport Sewage Treatment Works .
