I thank the member for some notice of the question.
(1) The Water
Corporation assumes that the assets in question are located between Ellenbrook
and Alexander Drive. The sewer assets within this vicinity are primarily PVC
and vitreous clay. The oldest asset is a VC pipe laid in 1977 and the youngest
asset is a PVC pipe laid in 2011. These assets do not have a history of failure
and are currently not scheduled for replacement within the next 20 years.
(2) The Water
Corporation will be responsible for potential future renewal or upgrade. The
theoretical replacement value of the sewer pipes within Gnangara Road equates
to $1.4 million.
(3) The pipeline is not scheduled for renewal.
