CPG Consultants was appointed by PUB, Singapore's national water agency, to provide complete engineering consultancy services, as well as Project Management, Quantity Surveying and Contract Management for the Punggol-Serangoon Reservoir Scheme.

We managed this project from design to construction, developing and implementing the Environmental Monitoring and Management Plan for the construction of Punggol and Serangoon reservoirs.

A feasibility study of the Reservoir Scheme and a yield study were carried out, and a flood management study was conducted to assess flood implications. Thereafter, the Punggol and Serangoon Rivers were dammed up to create two new freshwater reservoirs that would provide reliable long-term water supply for Singapore.

In addition, water quality modelling and contaminant source assessment were carried out to predict water quality in the reservoirs.
