Project Description

The project comprised design and construction supervision for major sanitary sewers and stormwater drains in an existing highly developed urban area. Works were intended to increase capacity, remove pollution from the stormwater system due to illegal connections of foul sewers, prevent stormwater infiltration to the foul sewers, and improve overall stormwater drainage system hydraulic performance to lessen flooding. The planning inputs consisted of population forecasting and development scenario building to input to drainage/sewerage system capacity modelling.
