Age of sewer pipeline not a factor in Beaconsfield spill as park prepares to reopen
Water Corporation expects to hand the reserve back to the City of Fremantle on July 21, after the re-turfing of the grass is complete.
'Once handed back to the City, the park will be safe for public use,' a Water Corp spokesperson told The West Australian.
However, questions have been raised about WA's water and sewerage infrastructure system as investigations continue into the cause of the sewage pipe failure.
Asked by Nationals deputy leader Peter Rundle if a similar incident was likely to happen again, Water Corporation boss Pat Donovan told State Parliament that the pipe that burst was still well within its expected service life, so there is no clear explanation for the failure yet.
'This was a unique event, in that it was a pipeline that was well within its asset lifespan; it was a 1966 pipeline,' Mr Donovan told State Parliament during estimates on Thursday.
'The pipeline itself has an asset life of about 80 years, so we are still working through exactly what occurred in terms of the root cause of the incident.'
Less than two weeks after the incident, the State Budget was released, which included an additional $35 million for the Water Corporation's asset maintenance budget.
It's believed the burst in Beaconsfield occurred after sewage was diverted to the area, to relieve pressure following another sewage burst in Spearwood.
It took the Water Corp several days to repair the burst pipe, causing considerable disruption to neighbouring residents.
Mr Donovan thanked all those affected by the incident for their patience during the fix of what was 'undoubtedly a very unpleasant situation,' and said the corporation would learn from the incident.
'As we do with all such pipeline failures, we will be making sure that we learn from it and that it informs our asset management system going forward in terms of where we need to do proactive maintenance, further inspections or, indeed, asset replacement', he said.
'We will continue to ensure that we understand exactly what happened and make sure that we feed that back into our asset management system.'

Age of sewer pipeline not a factor in Beaconsfield spill as park prepares to reopen
Bruce Lee Oval in Beaconsfield is set to reopen this month, weeks after a burst sewage pipeline left the park contaminated and flooded neighbouring streets. Water Corporation expects to hand the reserve back to the City of Fremantle on July 21, after the re-turfing of the grass is complete. 'Once handed back to the City, the park will be safe for public use,' a Water Corp spokesperson told The West Australian. However, questions have been raised about WA's water and sewerage infrastructure system as investigations continue into the cause of the sewage pipe failure.

Anti-Israeli graffiti attack on Parliament sparks camera upgrade and push case for ‘Post and Boast' laws
An anti-Israel graffiti attack has sparked a review of State Parliament's security cameras, after the incident revealed a gap in coverage. Senior staff told a Budget estimates hearing on Thursday that the night-time attack was only partly captured on CCTV. 'The area is actually under CCTV surveillance. However, it was at night time, and the cameras aren't the night vision type of cameras,' Parliamentary Services Executive Manager Rob Hunter said. 'So there is a need to upgrade our cameras across the whole precinct. They go into over 100 cameras, so that one there did capture some things, including the offender coming down Harvest Terrace.' Mapping has started but funding is yet to be allocated to upgrade cameras, six weeks after a door of State Parliament and the footpath in West Perth were spray-painted. 'We expect that this year we will see some upgrades in our cameras across the precinct,' Mr Hunter said. It was also revealed that the 22-year-old charged over the damage has since paid 'restitution' of $2200 for the clean-up. It was also revealed he had posted video of the crime on social media, but proposed 'post and boast' laws set to carry a maximum penalty of three years jail are yet to pass Parliament and did not apply.

Basil Zempilas 10 Things: Budget estimates show that some ministers are making guesstimates
1. It's called estimates, but after having sat through it front and centre this week, I reckon for some ministers it's more like guesstimates. Budget estimates is the brief political window which opens for three days every year in State Parliament following the Budget. Members of the Opposition have the opportunity to quiz ministers and senior public servants on the government's spending. With just a day to run, it's very clear which ministers know their stuff, and which ones have skimmed the briefing notes in the car on the way to work. 2. The other great curiosity of Estimates is which minister is responsible for answering which questions. Sometimes they don't even know. Like on Tuesday when I tried to ask about Roger's rugby team and was told by Tourism Minister Reece Whitby I'd need to ask Sport and Recreation Minister Rita Saffioti, who later in the day told me I'd need to ask the Tourism Minister. Yes minister. 3. The Deputy Premier was more forthcoming on questions about the racetrack at Burswood Park. I suppose when everyone calls it Rita's racetrack, it's hard not to own it. We learned the $217.5 million dollars the State Government has told everyone the racetrack will cost is only an estimate based on a draft assessment, not the final cost. The other revelation: no land needs to be acquired from neighbouring Crown Resorts to complete the racetrack. 4. That last point is particularly interesting, because it's not what community members were told at recent Optus Stadium consultation sessions. 5. Estimates also helped us better understand that the solar batteries households are signing up for under the $5000 State-Federal rebate scheme will actually be used to keep the lights on — for everyone. Energy Minister Amber-Jade Sanderson confirmed the power you store in your solar battery will be accessible by the Government to put back into the grid 30 times per year to help make up any peak demand shortfalls. 6. Here's something else I learned: to make the expansion of the ferry service possible east of the Causeway, the bridge may need to have some of its under carriage scraped away so the boats can fit underneath. 7. Remember the debt monster of 2017? It feels like he's warming up for a grand return. 8. My guess is most parents think two weeks of school holidays in the middle of the year is more than enough. 9. It's a footy moment most West Australians will never forget. Dom Sheed's match winner in the 2018 grand final was as good as it gets. Congrats Dom, enjoy the next chapter. 10. Huge congratulations to my old teammate Paul Sanzone on steering West Perth to a win in his first game as senior coach. The circumstances of him taking over may not have been ideal, but what a way to get the club back on track.
