THE threat of sewege seeping into the Swan and Canning rivers has prompted stakeholders to demand the State Government take action.
Swan MHR Steve Irons said nutrient seepage from properties not connected to the infill sewerage network in the City of Belmont and Town of Victoria Park was a major concern for the future health of the rivers.
He said the seepage was affecting water quality and contributing to algal blooms.
Connecting properties to infill sewerage should be a priority as nitrogen and phosphorus levels in the river were too high, he said.
Belmont Mayor Glenys Godfrey said nutrient seepage from unconnected properties, mainly in Kewdale, was a problem.
“Most of our residential properties have the provision to connect with the sewerage network but the Kewdale industrial region does not and this needs to change as a matter of urgency,” she said.
Town of Victoria Park sustainable development director Rochelle Lavery said industrial land and a small piece of land at the end of Goodwood Parade, which could be developed into a high-density residential property, needed to be connected to infill sewerage.
Ms Lavery said the State Government had advised that it was limited by the Budget and the most sensitive areas were prioritised for infill sewerage.
According to the Water Corporation, there are no projects left to be completed in the City of Belmont and Town of Victoria Park under the State Government’s Infill Sewerage Program.
The Kewdale Industrial Area was not included in the Water Corporation’s projects that needed to be completed.
