Southern Nevada Water Authority General Manager Pat Mulroy has called it the most complicated construction project in the country. It claimed its first victim yesterday when 44-year-old Thomas Turner was killed by a stream of grout and rock under high pressure. Workers have to descend an access shaft for more than 500 feet before getting to the work site. So is the job impossible? Can a tunnel be built through rock that is seeping water? What more should be done to ensure the safe completion of the third straw?
Judging from the vast and grand history of insanely difficult yet successful engineering projects this world has seen, I'd guess that a large part of the Water District's problem are the crap engineers that are graduated from the crap universities that are fed crap students by the crap K-12 schools these days. Truly, as any old-timer in the business would attest, most engineers of decades ago were far better than most engineers these days.Tim Hunt –Jun 13, 2012 13:22:19 PM
Why must the third intake be a tunnel? Why couldn't the "third straw" have been just that, a large concrete pipeline that runs down from the shore deep into the lake? The tunnel has already experienced several major geological failures. It is more vulnerable to failure than a pipeline, and more expensive and dangerous to construct or repair. Robert L.
