J.S. LEE Legislative Council Hallett Cove Pipeline In reply to the Hon. J.S. LEE (22 June 2016). The Hon. I.K. HUNTER Legislative Council Minister for Sustainability, Environment and Conservation, Minister for Water and the River Murray, Minister for Climate Change Hallett Cove Pipeline The Hon. I.K. HUNTER (Minister for Sustainability, Environment and Conservation, Minister for Water and the River Murray, Minister for Climate Change): As Minister for Water and the River Murray, I have been provided with the following advice: 1.	I am advised that SA Water has no records on why this location was chosen in 1977. 2.	In 1991, the 200mm main was damaged by excessive flooding within Waterfall Creek. As a result the main was cut and capped by SA Water and disconnected from the system. In the late 1990s, The City of Marion rectified the embankment and upgraded the stormwater drainage. As a result of the stormwater system improvements, SA Water reconnected the main to the potable water system in 2001. 3.	I am advised SA Water had to cut and cap the northern end of the 200mm main at Sandison Road. This allowed for the damaged section of main to be isolated from the rest of the network and enable water to be supplied to customers at a lower pressure. 4.	SA Water is currently in discussions with the City of Marion around their future maintenance strategy for the stormwater main.
