I thank the member for some notice
of the question. On behalf of the Minister for Housing, I provide the following
response —
(1) On Tuesday 17
May 2016, the Water Corporation isolated a large water distribution pipeline in
Mt Lawley as part of an annual pipeline inspection program. This changed the
direction that water flows through smaller pipes, stirring up naturally
occurring sediment, which is the cause of this temporary discoloured water.
(2) The water has returned to
normal.
(3) Perth's
integrated water supply scheme is tested on a regular basis. As the suspended
particles that cause discoloured water are harmless to health, additional
testing is not required.
(4) Yes, through
advertisements in The Perth Voice and
the Guardian Express .
(5) The Water
Corporation inspects pipelines as part of its proactive program of annual
maintenance and inspection. In most cases the isolations do not cause
discoloured water.
