 In 2009, when Brisbane City Council still managed the sewerage catchment system, the Council published a need for a New Sewerage Transportation Infrastructure due to local population increases resulting in sewerage catchment growth.The Council's preferred augmentation works involve "developing a greenfield sewerage system in Moggill and Bellbowrie" with 10 pumping stations that connect to Wacol WWTP being switched off.The likelihood of a greenfield sewerage system in Moggill and Bellbowrie in the foreseeable future is slim when considering the capacity of the Wacol WWTP is 8.4 ML per day but it is only treating 4 ML per day.
