GHD was commissioned by Manila Water Company, Inc. (MWCI) to analyse the effects of their proposed 165 MLD Ilugin Sewerage Treatment Plant (STP) effluent flow system on the floods in the heavily populated neighbouring areas in Metro Manila. GHD’s team formulated rainfall-runoff models and hydraulic models, which allowed for the development and testing of flood mitigation measures and upgrades and the existing flood management systems.
