The Water Corporation proposes to construct a wastewater pressure main from Monash Boulevard Pump Station to Bunbury Wastewater Treatment Plant and has referred a small portion of the pipeline between Verschuer Place and Southwest Highway, Davenport, to the Environmental Protection Authority (EPA). In considering the proposal the EPA notes that the section of pipe alignment referred intersects the corner boundary of a wetland mapped under the Environmental Protection (Swan Coastal Plain Lakes) Policy 1992 (Swan Coastal Plain Lakes EPP), Eeddles Gully.
