WONGAN HILLS TO MOORA
WATER PIPELINE
1117. Hon JIM CHOWN to the minister representing the Minister
for Water:
I refer to parliamentary question
without notice 1091.
(1) Why has it
become increasingly difficult to supply all customers, including those
connected to the Wongan Hills town water supply scheme, over the last five
years?
(2) What does the
maintenance program, as stated in parliamentary question without notice 1091,
entail, including the cost of increasing the performance of the pipeline?
(3) When was the maintenance program
initiated and what is the expected completion date?
Hon
ALANNAH MacTIERNAN replied:
I thank the member for the question.
The following information has been provided by the Minister for Water.
(1) Increased
demand on the system over the last five years has meant that properties with no
restrictors installed on their water meters were causing supply issues and
giving an inequitable supply to customers along the scheme. Flow restrictors
are an essential component of the scheme's design; this has been the
case since the scheme was installed in 1998.
(2) The
maintenance program ensures that appropriately sized restrictors are present on
all services on this scheme. The program does not change the capacity of the
pipeline; rather it manages the demand equitably for individual properties.
(3) Properties
have always required flow restrictors since the scheme was installed in 1998.
This program to install missing restrictors began in March 2018. The program of
works is now complete. Affected customers were provided with two months'
notice prior to the restrictors being installed.
