To replace an existing, malodorous treatment pond, a new sewage-treatment plant was built underground and, atop it, a leisure and sports park to serve the community. The pond was drained, and sophisticated engineering was required for the boring and excavation to prevent seepage into the surrounding areas and to avoid damage to nearby residential constructions and rail-lines; the underground plant is built of poured-in-place concrete. The parks above are irrigated with treated water from the plant and provide sports facilities for football, futsal, basketball, tennis, and volleyball, and a children’s park and jogging track. A new, indoor community centre also forms part of the project. The car-park is fitted with solar panels that generate electricity for the sewage-treatment plant.
