NBN adds 300,000 premises to fibre footprint, releases details of full coverage

what I don't get is this:

why is the NBN in most parts not being installed via the sewerage system?

seems Brisbane Council is thinking of doing it that way. should save them heaps.

You want to make dirty phone calls do you?

Possibly a great idea for ancient cities with many overlays, but almost totally useless here. Useless method in your street. Have a look at the cabling method shown on their web pages. Now imagine your current system which is likely to go crumble with heavy rain and imagine that stuffed down the sewer; 100% aggressive chemically laden water attacking any copper and variably refracting any light paths.

It might, just might be okay for some runs of NBN trunk cables in the short term.

Unfortunately, sewage systems are not just places of water and soft objects, but also get abused as a general toxic waste and anything we can flush down the dunny or fit down the pipe rubbish dump. Apart from the toxic environment, any hard object driven by storm waters can do a fair bit of damage.

1. Brisbane Brisbane Council is not responsible for the NBN.
2. Does Brisbane council manage the sewage system in Brisbane?
3. Any piece of fibre optic cable is not the NBN. Optic fibre in networks has been around for over 15 years and my SOHO has had it for over 10 years.

because of security, not to mention that maintenance would be a s*1t of a job

Note, given our cityscapes are still largely clean soil, under boring is probably a reasonable only installation method.

I always wondered how they would avoid potential problems with blockages with having cables wires in the pipes. Also if you have seen old sewer or stormwater pipes, they tend to wear away at the bottom. Wouldn't this also happen to cables submerged in constantly moving contaminated water (ie - the foreign objects in the water such as s*it dirt, paper etc would have an abrasive action ?)

Also how do they plan to mount the cables, just pull them through and leave them sitting in the bottom of the pipe, (I would think unlikely) or get installers to go into the pipe & fasten the cable to the roof of the pipe, (this would only work in really large pipes that you could get into to do this work, and would be very labour intensive and therefore costly - not to mention the OHS requirements.)

Brisbane have an old sewerage system beneath the city.

I think some readers of this thread may be misreading what Brisbane Council has said.

It appears to be based a on google joke:

Because it makes a lot more sense to do it on the power poles or by punching it thru the nature strip.

More fool BrizVegas Council.

Nope, it actually costs a lot more except in the CBD itself.

That isnt even possible with sewers in suburban areas, they arent anything like that big.

And there are none of those in suburban areas.

OHS requirements.)

And there is the tiny matter of getting out of the sewer at each house in spades.
