The objective of the Project is to augment existing water resources within Sg Johor basin by an estimated 400 Mld in addition to controlling salinity intrusion to ensure the existing water intakes are not affected adversely by high saline content in the raw water.

The Feasibility Study includes River and Coastal Modelling (Rainfall-Runoff modelling, River Hydraulic Modelling involving hydrodynamic and advection dispersion to model salinity intrusion due to tidal effects of seawater), Environmental Study (physico-chemical assessment, habitat assessment and biological assessment of selected sections located upstream and downstream of the proposed barrage), conceptual design and application for planning permission.

The Project requires close liaison with various stakeholders including the Johor State Economic Planning Unit, Badan Kawal Selia Air Negeri Johor (BAKAJ), Syarikat Air Johor, Jabatan Bekalan Air, Jabatan Pengairan dan Saliran (JPS), Public Utilities Board of Singapore, aquaculture operators, Department of Fisheries and local communities.

Various value management workshops are held at concept and detail design stages attended by key project members from the firm. In addition, Risk management profile and reporting is also required by the Client.

The detail design and construction for the Project involves multi-disciplinary teams of professionals and considers the needs of JPS/PUB Singapore in the operation and maintenance of the barrage.
