ABC Design Features @ Sungei Ulu Pandan

ABC Water Design Features are systems that help to minimize the hydrological impact of urbanized catchments and to help safeguard the water quality going into our reservoirs and waterways. They also beautify the surroundings, while also improving biodiversity around the developments.

Sedimentation Basins

Sedimentation basins are ponds that are installed to allow stormwater to be stored and will allow coarse to medium sized sediments to settle. The cleaner water in the upper part is then transferred to a downstream treatment feature to be further cleaned, used for irrigation or conveyed to a receiving waterbody.

Vegetated Swales

Vegetated swales are a more natural drainage system compared to concrete drains. They are used to convey stormwater at a slower speed to allow settlement of coarse to medium sized sediments and to reduce erosion downstream.

Floating Wetlands

Floating wetlands are a category of constructed wetlands where plants are grown on a floating mat on the surface of the water. Specific plants are chosen and the roots of these plants take up pollutants from the water and serve as a natural environment for microorganisms that break down organic pollutants in the water.

Rain Gardens

Rain gardens, also known as bioretention basins which are depressions that are designed to detain and treat stormwater runoff. The runoff is first filtered through dense vegetation before percolating through a filter media (soil layers) to remove fine sediments and soluble pollutants before being transported out of the bioretention basin.

Cleansing Biotopes

Cleansing biotopes are a form of constructed vertical flow wetlands with plants that are specifically chosen based on each species ability to remove a certain pollutant prevalent in the water. The degradation of pollutants by microorganisms also occur in the layers of substrate. The substrate also filters out particulates and have mineral composites that bind and remove phosphates.
