Outline solution development involved extensive investigation to confirm ground conditions and verify the location of existing services with each discrete project solution verified under the holistic drainage area catchment model to ensure mutual compatible & interdependency.
Typically each discrete project comprised upgrading & upsizing of the existing sewer and the construction of a large attenuation chamber with screened overflow outfall pipeline to the nearby watercourse.
