Analysing the ECOasis fronting Singapore Polytechnic’s FoodCourt 2
In Singapore, a Typical Plaza usually have its landscape and hydrology as a separate system. They often have water features however, they are seldom natural elements. The pools are typically tiled concrete with minimum to no landscaping and plants are also often for aesthetic purposes planted in separate pots and planters. Their water features are seldom for storm water management and often replenished with fresh tap- water.

In contrast, the ECOasis fronting the Foodcourt 2 is an integrated ABC Plaza Design. As it is designed to adopt the Active, Beautiful and Clean waters, ABC Waters programme by PUB.
Firstly, this ECOasis is constructed with up to 50% of recycled materials such as sustainable composite timber and recycled concrete slabs. The plants and flowers affected by renovation within the campus are relocated to this ECOasis instead to being discarded.
Secondly, rainwater that is collected at the roof of the linkway bridges and buildings which are incorporated in the design is then diverted to the collection tank through rainwater downpipes. The collected rainwater will then go through a natural filtration process through terraces with plants before being discharged into the pond. When the capacity of the pond has reach its maximum, the excess water is stored in an underground storage tank and used recycled to be used as irrigation for the plants and to replenish the mini waterfall instead of using fresh water or discharging the excess water. This can help to reduce the consumption of fresh potable water.

Thirdly, the plants and water features are incorporated as part of the ECOasis instead of being separated. Other than begin an aesthetic water feature to beautify the environment, the plants also act as a cleaning agent by cleansing the water naturally by trapping particles, taking in nutrients and other pollutants hence, improving the water quality.
Fourthly, the design of this ECOasis incorporates the linked bridge and platform instead of being separated. This design allows the linked bridge and platform to act as a collection point for rainwater and at the same time the beautifying the area and providing a conducive outdoor environment for learning and working.

Lastly, the ECOasis also uses solar panels to generate power for use at ECOasis and surrounding.

In conclusion, this ECOasis is designed as an integrated plaza with ABC waters design features such as plants acting as a natural filtration system, excess water used as irrigation, incorporated landscape features, underground storage tank and solar panels which simulates water collection, filtration, retention and recycling. These features help to keep the ECOasis self-sustainable which requires low maintenance, a dynamic yet conducive environment. Therefore, the ECOasis at food court 2 is an integrated Plaza with ABC waters design features.
