WA's greatest engineering achievement - The Golden Pipeline
The Golden Pipeline, otherwise known as the Goldfields Water Supply Scheme, the Coolgardie Water Supple Scheme and lastly, the Goldfields and Agricultural Water Supple Scheme transports water from Mundaring Weir to Kalgoorlie.
It was badly needed once the gold rush began in the 1890s. There is little rain and no natural water sources in the goldfields. As such, diseases like Typhoid Fever were running rampant.
A solution was desperately needed and the premier at the time, John Forrest, enlisted an Irish engineer named C.Y O'Connor to devise a scheme. The freshwater pipeline would be nearly 600km long - an engineering feat yet to be achieved worldwide. This project drew large amounts of criticism from opposing politicians and the press. Its predicted cost was equal to the colonies entire annual budget.
This was all too much for O'Connor, and in one of the biggest loses the state would ever see - he took his own life after riding his horse into the ocean south of Fremantle.
The project was ultimately a success and it's a shame he couldn't see its completion. In this video, I will deep dive into the projects planning, construction and numerous upgrades and extensions over the decades. I'll also take you on a grand tour of the entire pipeline. This includes Mundaring Weir, Toorak Hill in Coolgardie, Mount Charlotte Reservoir in Kalgoorlie and the site of eight steam pumping stations. These are found in locations such as Cunderdin, Merredin, Yerbillon, Ghooli, Gilgai and Dedari.

SOUTH PERTH SWEPT OUT TO SEA
9th February 1902
https://trove.nla.gov.au/newspaper/article/32722146?searchTerm=C%20Y%20O%27Connor
Corruption by contract. The Sunday Times. Referred to the construction contract as a “swindle”. They claim O’Connor had flourished on palm grease. The article goes on with all sorts of personal attacks and accusations of corruption. It’s a very wild read in hindsight, knowing just how much of a success the pipeline is.
“We cannot escape the conclusion that O’Connor is a palm-greased humbug who has imposed on this state the first he entered upon his duties.”
28th February 1902
https://trove.nla.gov.au/newspaper/article/203480840?searchTerm=C%20Y%20O%27Connor
O’Connor himself replies stating the facts about the budget blowouts and corruption are incorrect, stating his figures. It should be noted how small this rebuttal is on a page… and is not even posted in the Sunday Times. Couldn’t find such a reply printed there
From my research, this reply was posted in the Western Mail, the West Australian, the Evening Star and the Coolgardie Miner – but not the Sunday Times.
1st March 1902
https://trove.nla.gov.au/newspaper/article/37795492?searchTerm=C%20Y%20O%27Connor
Same statement as above but easier to read. Addresses some inconsistencies but says “There are very many similarly erroneous statements in circulation at present, which I hope to have opportunity of replying to shortly : but this one is so important, and has been so often repeated, that I think it is desirable to reply to it without further delay."
Sadly, O’Connor would not have the opportunity to prove himself further.

His horse was found wandering around scrub by itself. A short search found his body in the water, but close to the shoreline and Robb Jetty. He was 58 years old.
He was involved in railway works in his native Ireland before immigrating to New Zealand
It appears the Sunday Times didn’t even report on his death, but they were quick to turn their attention to Hodgeson. Their comment, as per their own quote in the bellow 3rd of August article six days after his death “At the present we prefer to say nothing even in justification of our past attitude towards the man when living, beyond saying that towards him, as towards all others, we have always been actuated by the highest sense of public duty, which we cannot forget even in the presence of death itself. We are content to wait for the vindication of time.”
They use the commission as an excuse to say O’Connor was now instead lead on by Hodgeson. They referred to him as “Chief Robber”. The article goes on and on to accuse him of all manner of wrong doings, mostly relating to loans. You can find it in my sources if you’d like to read it, follow a link in the description

https://trove.nla.gov.au/newspaper/article/57217650?searchTerm=O%27Connor
They turn their attention to Hodgson, being so bold to claim he caused the death of O’Connor. They finally address his suicide, only to state “His untimely decease was a shock to the community, and there were people despicable enough not to trace his strain of mind and its sad unhinging to the fraudulent Knaves at Work on the pipe track, but to our exposure of them.”
They even admit that O’Connor had shown the newspaper article to Hoskin’s and had told him that it was more than he could bear.
