Projects


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.

CURRENT PROJECTS

RAINFALL AND RUNOFF GUIDELINES

This project aims to develop a consistent set of guidelines to direct rainfall runoff and flow modelling across New Zealand catchments. The need for consistent rainfall and runoff guidance has been raised by individual members, the Modelling Special Interest Group and the Rivers Group.

HEALTH AND SAFETY GUIDELINES

This project is developing an online framework to ensure that water industry personnel have access to contemporary resources for managing Health and Safety.

WIPES BLOCKAGE REDUCTION

Water New Zealand has an advisory group coordinating initiatives to reduce wipe blockages in the sewer network. Work overseen by the advisory group includes standards development, co-ordination of communication messages and studies to the understand the origin of wipes in the sewage network.

ORGANIC MATERIALS GUIDELINE DEVELOPMENT

Guidelines for dealing with organic wastes are under development. The guidelines will supersede 2003 Guidelines for the Safe Application of Biosolids to Land and include other organic material such as animal manures, which also contain pathogens and contamninants Water New Zealand, WasteMINZ, the Centre for Integrated Biowaste Research (CIBR) and the New Zealand Land Treatment Collective (NZLTC) are collaborating on their delivery. A draft manual will be available for targeted consultation and public comment shortly.

ASBESTOS CEMENT(AC) WATER MAINS DATABASE, MANUAL AND LIFE PREDICATION MODEL

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.

WASTE STABILISATION POND GUIDELINES

Previous work and contemporary New Zealand and International expertise is being collated to develop guidance on operations and maintenance, desludging, decommissioning and advanced microbial digestion in waste stabilisation ponds (oxidation ponds).

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: lesley.smith@waternz.org.nz

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 and swimming pools. BECA is leading the development of the guidelines.

RESOURCE CONSENT CONSISTENCY FOR WASTEWATER TREATMENT

Opportunities for greater consistency in discharge consent compliance practices were reviewed at two 2014 workshops. Outcomes are listed in workshop proceedings and outputs. Water New Zealand are in discussion with a range of government departments to advance these outcomes.

Hygiene Guide

This project will provide guidance material outlining codes of practice to prevent water supply contamination by providing water and wastewater operators and managers with reference material on hygiene good practice.

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


Code of Practice for Water Metering Updates

Water New Zealand technical staff will draw on the experiences of a WSMG advisory group to complete the updates to the existing water meter code of practice and disseminate outcomes.


SUPPORTED PROJECTS

META DATA STANDARDS

National metadata standards are being developed to provide a consistent approach to the way data on 3 waters is captured, described and stored. LINZ is leading the project in collaboration with a large number of stakeholders.

PIPE RENEWAL PROJECT

Water New Zealand the Quake Centre and IPWEA are pleased to announce the release of Evidence Based Investment Decision Making for 3 Water Pipe Network Programme (Pipe Renewals Guidelines Programme). The three organisations have agreed to work co-operatively to develop guidance documents and tools to assist New Zealand’s water organisations to make nationally consistent, evidenced-based decisions relating to the management and renewal of their 3 Water Pipe Networks. The programme covers inspection, maintenance and renewal strategies for pipework in potable water, wastewater and stormwater systems.

UPDATING TP58 - ON-SITE WASTEWATER SYSTEMS: DESIGN AND MANAGEMENT MANUAL 2004

Auckland Council are updating this document as part of a complete series review to create a practical, user-friendly document that is up to date with the current technologies and practices in the industry. Water New Zealand is on an advisory group and will record and use the project information to later create a national use guide on this topic. For progress on the Auckland design guides see: http://www.aucklanddesignmanual.co.nz/about-the-adm#/about-the-adm/what-is-adm

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.


Project Proposals

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.
