Programme Overview

November and December 2018, has seen the 3 waters project team further continue to design

and tender for design partners and be well placed to start 2019 on the front foot to deliver our

large capital works programme.

Some key areas we have concentrated on in the last 2 months are;

- Building relationships with landowners, resulting in approval to construct a test bore, which

with positive flow and quality results may lead into our production bore for the Waipukurau

second water supply

- Working with Hawkes Bay Regional Council to finalise the resource consent extension for

the Otane Wastewater treatment plant upgrade

- Great progress with the Porritt place water renewal project (at 75% complete).

- Commission the new wastewater pump and complete all physical works at the Otane land

development site.

- Complete the 150mtr water pipe between the Otane land development and the new

Otane alternate supply

- Receive a 3 year extension for the Takapau wastewater treatment plant.

- Continue to develop relationships and understand what the community wants as we move

towards a best practicable option for the CHB wastewater project

Below are some photos that were taken at #thebigwaterstory launch on the 23rd August 2018.

PROGRESS 20%

BUDGET $1.7m

TOTAL PROJECT $67k

SPEND TO DATE

RISK LEVEL

SCOPE

To renew approx. 2200m of 375mm glazed earthenware pipe that is known to have poor leaking

joints and allows a great deal of infiltration into the pipework through tree root intrusion and cracks

20 Dec 2018, the recommended option is to pipe-burst with an upgraded 400mm PE, and small

pump station upgrade.

PLANNED

Update optioneering study with CHBDC feedback following workshop, finalise preferred option

and commence concept design drawings.

Undertake extensive stakeholder engagement with the stakeholders that may be affected by the

renewal works.

RISKS

Some early risk identified within this

project;

- Unknown current condition
