Current Projects are the projects Water New Zealand is currently leading.
Supported Projects are the projects Water New Zealand is contributing to but are lead by another organsiation.
Project Proposals provides information related to submissions for new projects stakeholders feel Water New Zealand should be involved in or lead.
The sector currently has an aging workforce and limited succession planning. We need to attract people into the sector and retain them but, in general, the sector is not as attractive or competitive as other sectors that compete for similar skill sets. The sector’s capability needs are also changing in response to tougher environmental standards, greater assurances being required around public health and safety, as well as efforts to lift the bar on asset management practices across the country. Some organisations are tackling these issues and there is an opportunity to share these learnings through greater industry collaboration. Vocational education and training will need to evolve in response.
A project to explore these challenges and develop a strategy and plan of action for resolving them is being kicked off in 2018. The timing and details for the project are currently being worked out.
Water NZ wants to see members get actively involved in this important initiative.

There is widespread support within the 3 waters sector for developing national rainfall and runoff guidelines. For over seven years, groups such as the Engineering NZ/Water NZ Rivers Group and the Water NZ Modelling and Stormwater Special Interest Groups have consistently identified this as a priority sector need.
National guidelines would support improved decision-making and cost efficiencies on matters such as natural hazard risk assessment (especially for floods) and right-sizing infrastructure investment in the face of climate change; including flood protection schemes, stormwater systems, wastewater systems and transport infrastructure. The work would also benefit wider freshwater management such as decisions about how to best improve water quality or address water quantity pressures.
A Steering Group has now been established to drive the work forward. There is no funding for the work yet. The current approach is to break the work into manageable chunks and prioritise effort on some priority sub-projects. A screening survey has been completed and four projects are now underway.
It is important to note that this project is not a Water New Zealand led project. The Steering Group is providing overall leadership as there are multiple interests in this initiative. Water New Zealand is providing project management support.
The International Water Services Flushability Group (IWSFG) is a group of water associations, utilities, and professionals seeking to provide clear guidance on what should and should not be flushed down the toilet to protect customers, wastewater systems, their workers, and the environment.
On behalf of the New Zealand wastewater sector, Water New Zealand has signed a MoU with the IWSFG.
This objective is supported by Publicly Available Standards (PAS) documents setting out the test protocols and other information supporting and referenced in the standard.
This group are creating an international PAS to determine the requirements of what is flushable. Some of the current actions are:
- Finalise the 3 draft test methods, the final test methods are expected to be published early January 2018.
- Confirm logo
- Industry consultation
Guidelines for beneficially reusing organic materials on productive land are under development. The guidelines will supersede 2003 Guidelines for the Safe Application of Biosolids to Land and include additional organic material such as animal manures, and other agricultural wastes, which also contain pathogens and contaminants. Water New Zealand, WasteMINZ, the Centre for Integrated Biowaste Research (CIBR) and the New Zealand Land Treatment Collective (NZLTC) together with the ministries of Environment, Health and primary Industries are collaborating on their delivery.
Nick Walmsley ran five regional meetings to discuss a draft during February 2017, which over 100 people attended. Meeting notes are available here. Twenty-three submissions from 36 individuals and organisations were subsequently received. The project Steering Group held a meeting to consider these submissions on 27 April 2017 and formulated a programme to update the draft . The Steering Group meeting notes and full copies of the submissions can be viewed here.
The updated draft documents are now available for further public comment here. Submissions on this second draft will close at 5pm Friday, 9 March 2018. It is intended that the guidelines will be published by mid 2018. There will be no regional meetings to cover the second draft guidelines. Submissions should be emailed to firstname.lastname@example.org
The database contains test data on AC pipes around New Zealand and is used as the basis of lifetime prediction and analysis curves. The accompanying manual provides specifications for sampling, testing and condition grading. Information in the manual and database is being updated and expanded to include contemporary information and improve usability.
The contents of the manual have been finalised. Workshops to assist users of the model implement their contents are under development. To register your interest in attending contact email@example.com.
Water New Zealand is happy to provide the long awaited Good Practise Guide for Waste Stabilisation Ponds: Design and Operation, We believe this guideline will be of great value to the industry and likely to be a long serving legacy document referred back to by members for many years to come. This is a document the authors can be proud of and Water New Zealand would like to acknowledge the many hours of dedicated effort the authors put in to creating this document.
This document is an update of the Ministry of Works Guidelines for Oxidation Ponds 1974. It follows the NZ Water and Wastes Association (NZWWA) 2007 draft Waste Stabilisation Pond Guidelines which were published as a 2nd draft but never finalised and it draws on recent research and practices. It is primarily written for those involved in wastewater treatment pond management and operations: local authorities, regional councils, and wastewater systems operations personnel. As well as management and operations, these guidelines include basic aspects of pond design, planning, cultural acceptance, and regulations. It is assumed that the reader has an understanding of basic wastewater terminology.
It is Water New Zealand’s intention to hold a number of provincial workshops in the first quarter of 2018 explaining the content and thinking behind this guideline.

CHLORINE EMERGENCY MANAGEMENT PLANS AND GUIDE
This project will provide good practice guidance on the development of Chlorine Emergency Response Plans for water treatment plants, wastewater treatment plants.
Additional modelling has been carried out to calculate the theoretical release rates from chlorine drums and bottles while they are in use.
This project has been parked while a number of issues have been worked through; this includes the Chlorine Institute recent suspension of Pamphlet 74, Guidance On Estimating the Area Affected By A Chlorine Release.
GOOD PRACTICE GUIDES FOR THE SUPPLY OF WATER TREATMENT CHEMICALS
In 2016 revisions where incorporated into good practice guidelines for the supply of chlorine, Aluminium Sulphate, Hydrated Lime, and Polyelectrolyte. These can be found in Water New Zealand's Library. Ministry of Health is undertaking further work to determine chlorate levels in Drinking Water Supplies. This work will be completed and incorporated into chlorine guidance document in 2018. The chlorine guideline has been provided as provisional advice until this amendment.
The guidelines provide purchasers, manufacturers, and suppliers with the minimum physical, chemical and testing requirements for drinking water chemicals to meet safe limits. To ensure limits are met all operators should request a certificate of compliance when purchasing chemicals for use in drinking water, in accordance with processes outlined in the guide. Water New Zealand has an interest in the effective implementation of these guidelines. To assist us monitor this, we would appreciate copies of your certificate of compliance and associated lab results. Please send these to: email@example.com
Opportunities for greater consistency in discharge consent compliance practices were explored at two workshops held in 2013 ( click here for presentations and notes from the workshops). The project is being reinvigorated in 2018 after a hiatus due to resourcing challenges. Water New Zealand is developing an issues and options paper that will build on the issues raised at the earlier workshops and consider what has changed since 2013. A set of discussion questions will be identified and the intent is to workshop these with interested parties.
If you would like to get involved in the project please contact: firstname.lastname@example.org
Good Practice Guide for Developing Pressure Sewer Systems
This project will provide industry guidelines to assist local authorities’ decision making on pressure sewer systems. As there is currently no guidance or standard specification for pressure sewer systems in New Zealand the purpose of the guide is to address this gap in order to;
- reduce up front cost in the development of policies and standards
- reduce the inconsistency in equipment specifications to reduce cost and complexity for suppliers
- facilitate the sharing of existing knowledge to improve the effectiveness of pressure sewer systems
- Provide a tool to assist in the selection of pressure, vacuum and gravity sewer reticulation.
This project is expected to be completed in the first quarter of 2018.
UPDATING TP58 - ON-SITE WASTEWATER SYSTEMS: DESIGN AND MANAGEMENT MANUAL 2004
Auckland Council has given Water New Zealand approval to use GD06 (the old AC TP58) to convert to a national Water New Zealand guidance document. Water New Zealand will be establishing an industry advisory group to agree the scope of the rewrite. We anticipate the work starting in June and being completed by year end.
The objective of the national metadata standards are to enable the sharing of evidence based decision making practises for national infrastructure assets across New Zealand, this will aid in providing a consistent approach to the way data on 3 waters is captured, described and stored.
The ownership of the 3 water standards has transferred from LINZ to Water New Zealand
The project has now progressed to a practical application by willing entities that are prepared to implement the standards. The first quarter of 2018 should see a gap analysis completed of the differences in attributes collected by the willing entities, the following workshops discussing these differences will lead to what is considered the core set of attributes required.
There will be additional workshops on implementation of the volume 2 to follow.
Currently there are 5 willing entities supporting 53% of New Zealanders that are prepared to implement the Metadata standards. If your entity would like to join the willing, please contact email@example.com

RESIDENTIAL END USE STUDY
Water New Zealand is supporting a BRANZ research investigation to improve the understanding of residential water use in New Zealand. The building research levee has approved $290,000 to be delivered over two years to fund the project. Council participation in the project is currently being sought.
The Deep South Science Challenge, hosted by NIWA, is a research collaboration between a number of Crown Research Institutes, universities and research providers. The challenges mission is to enable New Zealanders to adapt, manage risk, and thrive in a changing climate. Water New Zealand’s technical team is providing input into a Representative User Group to inform and disseminate relevant research on the impacts and implications of climate change on urban water systems. The science challenge has also provided $7,000 to support an interactive climate change session in this year’s modelling symposium.
Water New Zealand’s technical team are part of the Advisory Group for the “Distributed Infrastructure” work stream of the Resilience Challenge. This is one of the government funded National Science Challenges that aims to develop and apply new scientific solutions to transform our preparedness, response, recovery and “bounce-back” from our wide diversity of natural hazards. This is a collaborative project across a wide range of research institutions, and a key part of this process is the development of outcomes shaped by stakeholder or ‘co-creation’.
The aim of the Distributed Infrastructure work stream is to develop an improved understanding of the resilience of spatially-distributed infrastructure networks to extreme natural hazards, with a focus on incorporating network functionality modelling into this work. More information on the wider challenge can be found at https://resiliencechallenge.nz/ .
Water New Zealand collaborates with a range of stakeholders to deliver projects that pool the collective knowledge of our membership. Projects are funded through; Water New Zealand finances, government funding, project participant fees, or grants.
Most projects are driven by Work Plans of our Special Interest Groups and Water Service Managers Group. Members may also propose projects, where support of the broader membership and outputs benefiting the New Zealand Water industry can be demonstrated.
