Cockburn Sound to benefit from BP tie-in to Water Recycling Plant.

Release date: 04 November 2009
Minister for Water, Hon. Dr Graham Jacobs will officially launch the BP Kwinana Refinery’s $13 million tie-in to the Kwinana Water Recycling Plant, on Tuesday November 3 2009.

The tie-in is significant because, for the first time in the BP refinery’s 54 year history, there will be no process industrial waste water discharged from the refinery into Cockburn Sound.

Instead, the treated waste water will now be piped through the Water Corporation’s waste water infrastructure to the Sepia Depression, 4.1 kilometres offshore from Point Peron.

While all BP’s process water undergoes rigorous treatment prior to discharge, it is, however, preferable to have this water returned further out to sea, beyond the relatively low-flushed waters of Cockburn Sound.

Today’s tie-in launch is the completion of a two stage process. As part of phase one, BP began piping high grade industrial water from the KWRP plant to the refinery, through glass-reinforced epoxy pipes, for industrial processes such as steam generation and cooling.
BP’s switch to reclaimed water have freed up nearly 2 gigalitres – or 800 Olympic size swimming pools - of potable water each year, for public use.

A future proposal to extend the use of KWRP water for firefighting and other industrial purposes could see this increase by another 1.3 megalitres per day.

BP Refinery Managing Director Thys Heyns said that the refinery had focused on reducing its dependency on pure scheme water for industrial purposes.

“In the mid 1990s BP drew 7ML a day from town scheme water resources for industrial uses. Through a series of water reduction programs that amount was reduced by 70 per cent by 2006. The introduction of KWRP further reduces our scheme water dependency to about 10 per cent of our mid 1990’s requirements,” Mr Heyns said.

“BP is committed to sustainable business. Projects such as KWRP embody our company’s core value of responsibility”
