How will Watercare support intestification when their network is stretched already?

Watercare have now only got just over 10% capacity remaining in their existing network.

With Watercare stating that they have approx 435,000 connections and an estimated 45,000 connection capacity remaining they’ve basically signalled that their networks cannot service the city.

The booming population is affecting housing, traffic as well as something a little less noticeable – water.

Two future water pipelines are likely to be installed to cope with the massive population growth in west and north Auckland.

Watercare is lodging applications to secure the routes for the pipelines that will run across the Upper Harbour area.   

The pipelines will boost network capacity in stages, as it is need over 30 years, for future housing and commercial development.

So how the hell will Auckland Council’s compact city be achieved?

Auckland Council’s own reports state that replacing network pipes in existing suburbs is more expensive than connecting up greenfield suburbs.

Brilliant! That’s an own goal.

They’re basically stuffed it up and soon all the intensification they want will grind to a halt.

    Typo in headline: “intensification”

  • Red_NZ

    but through depreciation, don’t they already have the money in the bank to pay for the required infrastructure upgrades?

    • Raibert

      Should do as they have been collecting it! Also past councils seemed to be able to provide infrastructure for new development, but this council uses cost of new infrastructure as a reason for stalling green fields.

  • George Carter

    Certainly this was probably used as an excuse not to build out but to build up. Unfortunately it’s starting to backfire on the council. You can’t have it both ways guys!

  • Orca

    I can’t believe that there has been no real discussion about the effect of intensification on the infrastructure. Even watercare are only referring here to the north and west, what about central Auckland? And the infrastructure includes many things, roads, water, sewerage, power, telecommunications etc. Anyone remember not so many years ago when Auckland’s power supply failed, and the CBD was run off portable diesel generators and cables to nearby ships in the harbour?

    Yup, just double the population of the central area, she’ll be right, any minor problems like gridlock 24/7, no power, no water, no sewerage, your Council will, well it will……….ummm……well…actually….just sod off.

    • Raibert

      Yep, ask these questions of Penny Hulse in relation to the Unitary Plan process. Don’t think she has an answer.

    • Toby

      Your council will put your rates up and build a trainset

    How will they supply areas of intensification?

    This map shows how, note new watermains underway coming into isthmus and new trunk sewers coming out of isthmus. Plus future projects north and west

    • Raibert

      This link doesn’t work. Would also like to know timing of these proposed new mains.

  • MaryLou

    Geez you just need to see the massive works going on in Glen Innes right now to know 45,000 won’t take long to get through

    I’m always sceptical about numbers thrown about like this without any context.
    How about posing some further questions to watercare to really understand what 10% actually means.
    Is that number an average capacity across the whole network or is it the capacity left in the bottlenecks with the least capacity left.
    Is the limit in connections caused by an inability to supply more total volume or by bottlenecks in key sub systems.
    What is the maximum number of connections that could be supported at the supply end relative to the current number of connections (ie how much water does Auckland actually have).
    If limited by subsystems which key areas are under the most strain and what is their current utilisations.
