One the major prerequisites we need to build the houses we need to combat our housing crisis is infrastructure, without it, the development can’t happen. This post is about a highly but often forgotten element of infrastructure Three Waters – Water Supply, Wastewater & Stormwater. In part 1 I focused on Wastewater, part 2 focused on Water Supply, part 3 will focus on Traditional Stormwater Systems or Grey Infrastructure compared to Green Infrastructure.
The stormwater system is public pipes, manholes, catchpits and other assets which assist in collecting water from rain & safely managing it. The stormwater system in Auckland is managed directly by Auckland Council as opposed to Wastewater & Water Supply which is managed by Watercare.
The recent LTP has the following Stormwater infrastructure as needed
- Freeman’s Bay stormwater upgrades ($21m) Due to frequent flooding in Daldy Street, Fanshawe Street, parts of Victoria Street and Victoria Park upgrades are needed to address – 2017 – 2020
- Artillery Tunnel ($22m) Due to be completed this year this one-kilometre long tunnel from McLennan Park to Pahurehure Inlet will serve Takanini growth areas – 2015 – 2017.
- Takanini Conveyance Cascades ($22) New open channel incorporating cascading weirs and associated green space to convey the 100-year flood in Takanini growth areas – 2015 – 2019.
- Ports of Auckland Outfall ($22m) A new stormwater pipe to replace the existing pipe in poor condition on Quay Street – 2015 – 2019
- Oakley Creek Conveyance ($30m) Upgrading culverts and widening of Oakley Creek through Walmsley Park to convey flood flow to allow growth in South Auckland – 2015 – 2019
These projects are also integral if we are to provide for the growth to tackle this housing crisis, however, it is key that an integrated approach is taken to infrastructure where AC/AT/NZTA/Watercare/Panuku/Crown work together on each area as a complete package of Three Waters, Transport, Planning & Community/Social Services to make work & not in isolation of each other.
