1. What is the history behind the construction of Yishun Dam in Singapore?
Yishun Dam (formerly known as Lower Seletar Dam) was built in the early 1980s as part of the Public Utilities Board’s (PUB) Active, Beautiful, Clean Waters (ABC Waters) Programme. The dam serves to regulate the water levels in the Upper Seletar Reservoir and reduce flooding downstream in Yishun and Sembawang.
Before the construction of Yishun Dam, there were already two smaller dams – Thomson Road Dam and Kallang River Dam – upstream along the same waterway. However, these dams were not sufficient to manage flash floods that occurred frequently in Yishun and Sembawang during heavy rainfalls.
To address these issues, PUB started planning for a larger dam designed to better control water flow. In 1978, PUB announced plans to construct a new dam at a cost of $59 million and work began on its construction in 1984.
2. How was Yishun Dam built?
The construction of Yishun Dam involved building a concrete gravity structure across Lower Seletar Reservoir. This required diversion of the river while the dam was being built in order to keep water away from the construction site.
The first step was to excavate earth from the reservoir bed to make way for the concrete foundations and abutments of the dam. This involved blasting through rocks using controlled explosives.
Next, thick layers of concrete were laid down to form the base of the dam. This base acted as a foundation for the vertical columns and beams that formed its walls.
Large cranes were used to hoist huge steel frames into place before filling them with concrete. This process was repeated until both sides of the dam met in the middle, creating a single structure spanning 145 meters across and standing about 14 meters tall.
Finally, floodgates were installed on both ends of the dam to regulate water flow according to PUB’s requirements.
3. What were the challenges faced during the construction of Yishun Dam?
One of the main challenges faced during the construction of Yishun Dam was dealing with the large amounts of water in Lower Seletar Reservoir. Diverting and containing this water while building the dam was no easy task and required careful planning and engineering.
There were also concerns about noise pollution affecting nearby residents due to the use of heavy machinery and controlled explosives. To minimize these effects, work on the dam took place during daytime hours only.
The rocky terrain at the construction site also posed a challenge as it required special equipment and techniques to excavate through solid granite.
Environmental impact assessments were also carried out to ensure minimal disruption to local flora and fauna during construction. Measures were taken to protect existing trees, plants, and animal habitats in the area.
4. How has Yishun Dam benefitted Singapore?
Since its completion, Yishun Dam has provided numerous benefits for Singapore. It serves as a key component in PUB’s flood mitigation strategy for Yishun and Sembawang, reducing flood risks in these areas from heavy rainfall events.
The dam also helps to maintain a stable water supply for domestic and industrial use by regulating water levels in Upper Seletar Reservoir.
In addition to its functional purposes, Yishun Dam has become a popular recreational spot for locals and tourists alike. Its scenic views, surrounding parklands, and various water sports activities make it an attractive destination for outdoor enthusiasts.
Furthermore, with its incorporation into PUB’s ABC Waters Programme, Yishun Dam has helped to improve overall water quality in Lower Seletar Reservoir by promoting natural filtration processes through the introduction of aquatic plants and animals.
Overall, Yishun Dam continues to serve as an important piece of infrastructure that contributes towards Singapore’s sustainable development goals.
2. How did the local community benefit from the construction of Yishun Dam?
