At the ABC Waters Learning Trail@ Kallang River @ Bishan - Ang Mo Kio Park:
Nestled among the heartlands of Singapore, Bishan Park was a popular heartland park built in 1988 and had Kallang River running in a canal along the park's edge. In 2002, under the ABC Waters Programme, the park underwent a rejuvenation to integrate Kallang River into Bishan Park based on a flood plain concept. The river park was created by transforming the once concrete canal into a natural picturesque waterway. Through the use of soil bioengineering techniques, the Kallang River now meanders through Bishan Park. The project was officially completed in 2012.
Soil bioengineering techniques is a combination of vegetation, natural materials such as rocks and civil engineering techniques to stabilise the river banks and protect them from erosion. These techniques also create natural habitats that encourage wildlife species to thrive.
Kallang River, which passes through Bishan – Ang Mo Kio Park functions as a conduit for water from Lower Peirce Reservoir (upstream of Kallang River) to Marina Reservoir (mouth of the river). During heavy storms, water in the reservoir may reach its top water level and spill into Kallang River. Besides spillage, PUB would at times discharge excess water from the reservoir to prevent excessive pressure acting on the dam; this is called scouring. When scouring is taking place, the water in the park would rise and the warning lights will start flashing. This increase in water flow would cause the stepping stones to be covered with water. Though the water level may seem low, the public is advised not to use the stepping stones when they see the warning lights flashing.
The park holds plenty of educational opportunities simply take a stroll along the river bank or wade in its shallow waters to learn more about the flora and fauna that have made Kallang River@Bishan - Ang Mo Kio Park their home.
The cleansing biotope in the park offers effective water treatment while maintaining a natural and beautiful environment. The root systems of the specially selected plants in the biotope help to filter pollutants in the water before it feeds to the ponds in the park.
|Raffles Institution's Science and Geography Departments came to the site initially to do water quality testing and was excited by the idea of doing an interdisciplinary ABC Waters Learning Trail resource package for Kallang River@ Bishan- Ang Mo Kio Park, targeted at secondary school students. After almost a year, the trail was ready! The school's student facilitators also took the lead in bringing other school students within the vicinity on a trail during World Water Day 2012 and Singapore International Water Week Water Showcases 2012.|
|Bishan Park Secondary School's Humanities Department has initiated and developed a Geography Trail for their Lower Secondary students in 2012. This project is currently being tested out in the school.|
|An interest group called Friends of Kallang River @ Bishan Park has been set up by Mr. Francis Ooi, PUB's Volunteer of Water to facilitate the education, outreach and engagement of the park's surrounding stakeholders. They regularly conduct patrols and outreach programmes for residents around Bishan Park.|
|Anderson Junior College has initiated and developed an interdisciplinary ABC Waters Learning Trail package targeted Pre-University students. The trail covers mainly Science, Geography and History topics. The student facilitators from Anderson Junior College also played their part as water advocates by leading other students on the trail during World Water Day 2013.|
