Alternative infrastructure options can make commercially unviable land viable
Waterlea Estate is a greenfield residential community located on the fringe of the Ipswich City urban footprint, with the closest trunk wastewater infrastructure approximately 6km to the west. To service the proposed development by traditional conveyance methods significant trunk wastewater infrastructure would be required upfront. To delay construction of connecting infrastructure and reduce CAPEX & OPEX an interim servicing strategy is being implemented.
Investigations were undertaken to compare interim servicing solutions which were capable of supporting the
initial stages of development whilst remaining sustainable and feasible for both the developer and Queensland
Urban Utilities (QUU). These investigations determined that on site wastewater treatment and disposal could
meet the required criteria and provide flexibility for further development beyond the intial stages.
Stage 1 of the planned Sewage Treatment Plan (STP) will be capable of servicing a maximum daily wastewater
load of 250kL or 1,250 Equivalent Persons (EP) and has the potential for its capacity to be doubled. Initial
feasibility studies indicated that this interim strategy would have lower whole of life costs, while offering QUU
an opportunity to pilot a new approach for servicing fringe developments and providing crop irrigation for local
farmers to assist with drought resilience.
