Pukekohe East reservoirs

Providing resilience to Auckland's drinking water supply.​

Start-finish: October 2018 - 2020 
Location: 108 Runciman Road – corner of Runciman and Rutherford Roads, Pukekohe East
Status: Construction of reservoir 1: late 2018-2020

What’s happening?



In October 2018, we started building a new water reservoir at 108 Runciman Road, Pukekohe East. Reservoirs are built to store water, to ensure there is enough for Aucklanders to consume. In order to meet population growth and to make sure there is enough water, we will build the first of two reservoirs during the next two years. The second reservoir will be built when needed to meet demand. To ensure the reservoirs blend into the natural environment, advance planting has been done and we will do further landscaping and planting following the construction.

Runciman Road traffic management

To enable the commissioning of the reservoir, we will be doing some work outside 57 Runciman Road to allow access for the project construction. The work will start the week of 10 June 2019, subject to weather, and will take approximately one week to complete. There will be stop-go traffic management in place to allow these works to be carried out safely. Please follow all traffic management and construction signs. Working hours will be Monday to Friday, 7.30am to 5pm. We will need to undertake further works to complete pipe connections at two locations along Runciman Road at a later date. Updates will be provided in advance of this.

  • Completed GAP65 fill of the reservoir 2 foundation
  • Begun reservoir 1 settlement monitoring
  • Reduced the amount of traffic management signage outside the school area
  • Placed an overlay of clean rock on the site haul road to minimise tracking
  • Stabilised  landscape bunds not being currently worked on
  • Completed site office area
  • Settlement  monitoring report accepted  
  • Levelled out trial preload and building up 1m raft for reservoir 1
  • Complete raft foundation for first and second slab pours
  • Excavated for central valve chamber and outlet pipework underneath central valve chamber
  • Poured concrete reservoir floor slab quarter A
  • Finished fixing formwork reservoir floor slab quarter B
  • Installed outlet pipework underneath the central valve chamber and concrete encased
  • Poured concrete central valve chamber floor slab
  • Install precast walls central valve chamber
  • Begun fixing reinforcing central valve chamber wall stitches
  • Finished fixing reinforcing for reservoir floor slab quarter B

In the next 2 weeks, we will:

  •  Pour concrete for reservoir slab quarter B
  •  Finished central valve chamber walls
  •  Place inlet, outlet and transfer pipework underneath the reservoir 
  •  Complete concrete encasement inlet, outlet and transfer pipework

Noisy operations or night works will be:

  • Next night pour is scheduled for the 20 June, weather dependent. Backup concrete pour scheduled for 22 June. During these night works the main bulk of the concrete deliveries will be to site between 2am to 8am
Upcoming milestones - we plan to:
  • Finishing construction central valve chamber
  • Install pipework underneath reservoir 1
  • Pouring floor slab reservoir 1
  • Begin installing precast panels reservoir 
Enabling works

We have completed the initial works which included the installation of traffic management, roadside tree trimming and the construction of a private access way.  

The next phase is scheduled to start on the 1 July 2019 (weather dependent) with the location of services and the reconnection to the existing watermain. There will be traffic management in place, similar to the initial works and these works will involve noise, vibration and dust, however we will endeavour to keep disruption to a minimum, using best practice techniques. For those residents within the working site, your driveway access will be maintained.  

These works are expected to take 12 weeks and we appreciate your patience during this time. Letters have been dropped to those in the vicinity of the works, and VMS digital notice boards will be used to inform road users closer to the time.

What are the benefits?

The new reservoirs will:

  • Cater for increased water demand as the region’s population grows
  • Help us maintain a secure supply of water
  • Allow us to continue maintaining other parts of the water network.
