Projects

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.

Current Projects

Organic Materials Guide

Guidelines for beneficially reusing organic materials on land are under development. A draft is available at this link. 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 waste materials, that 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 have been collaborating on the delivery of these Guidelines.

Urban Stormwater Modelling Guide

Guidance is being developed to provide a nationally consistent and robust urban stormwater modelling process. The guide will ensure a standard and consistent approach to urban flood hazard modelling which will give certainty to councils and other end users. It is being produced with significant sector input to ensure the guide is owned and understood by the industry. The project will be completed in two phases. The initial phase is focused on collation of existing approaches, and gap identification. The second phase will develop a national urban stormwater flood hazard modelling approach. Project advisory is being supported by Stormwater and Modelling special interest groups, with funding support from the Department of Internal Affairs.

Monitoring to inform management of wastewater process emissions

Water New Zealand Climate Change Special Interest Group are developing a technical guidance note to supplement the Carbon accounting Guidelines for Wastewater Treatment. Guidance is being developed to share existing knowledge on the direct measurement of wastewater emissions, rationale for undertaking measurement, and possible mitigation options. Quantification and management of wastewater process emissions is an emerging area of science internationally. These guidelines capture the experience of New Zealand subject matter experts working in this space who are volunteering their time to produce the guide.

Good practice guide to Reservoir Maintenance and Security

The maintenance and security of reservoirs for water quality is an essential component of water safety planning to safeguard human health.

There are multiple sources of contamination for water supplies and reservoirs are amongst those sources.

Good practices related to reservoir design, inspection, security, maintenance, and cleaning are needed to prevent potential contamination. This document is being prepared by Water New Zealand staff to compile existing literature and field experience.

This is a Water Services Managers Group funded project and is expected to be completed in January 2024.
