Planning and Designing Stormwater infrastructure Towards a Zero Carbon Future – James Reddish, WSP
NZ’s progress against the Paris agreement targets has been slow. NZ’s plan to reduce emissions is based on the advice from the Climate Change Commission and the Government-developed National Emissions Reduction Plan, published in May 2022. Included in the plan, is an overview of the legislation, strategies and plans that 21 government agencies have written to influence reducing our emissions as a nation. Every geography, organisation and individual is on their own journey to understand what this means for them.
Practitioners involved in the planning and design of stormwater infrastructure have an opportunity to lead by example in developing and delivering on Government and organisational carbon commitments, towards zero carbon, particularly through nature-based or water sensitive design solutions. Our best chance of achieving this, in the timeframes our planet requires, is as an industry working together, sharing knowledge, and breaking down organisational and jurisdictional silos.
This workshop will facilitate the sharing of knowledge and give you the opportunity to work in small groups with other stormwater practitioners to apply best practice and discuss and develop ideas for lower carbon solutions to our stormwater challenges. Out of this workshop you will leave with tangible, lower carbon ideas for common stormwater problems, and the potential to apply a new way of thinking about your local infrastructure challenges.
National Urban Stormwater Modelling Guidelines – Rathika Jebamony, AWA (National Stormwater Modelling Guide Project Director) & Michael Arthur, Metis Consulting (Project Manager and Lead Author)
Aim: A collaborative approach to ensure the stormwater modelling guide developed is formed, owned and understood by industry
Objectives: To ensure we have collated and understood:
• Existing urban flood modelling approaches each region of New Zealand to determine:
o Where common approaches apply across New Zealand
o Where discrepancies exist
o Strengths and weaknesses of the various approaches in use
o Identification of the gape to overcome to arrive at a consistent national approach
• Potential future work packages to harmonise existing approaches
Te Ao Māori – Partnerships and Te Mana o te Wai
Aim: To present case studies of iwi partnership programmes by Mana Whenua representatives. It will include a workshopping element to encourage participants to look at their own mahi and how they can meaningfully give effect to Te Mana o te Wai.
Objectives:
- Examples/case studies by iwi/hapū kaitkai are given on projects with stormwater outcomes (both urban and rural examples).
- Attendees have workshopped Te Mana o te Wai in context to their own mahi and are left with a greater operational understanding.
- The significance and benefits of partnering with Tangata Whenua is understood as a necessity, ‘not a nice to have’.

Manufactured Treatment Device Maintenance Workshop – Stormwater360
Effective maintenance remains a barrier to effective functioning of many manufactured treatment devices. With over 20,000 of their treatment devices in the ground, Stormwater360 bring their knowledge and expertise in this workshop on the key techniques and checks required for effective and efficient treatment performance. SW360 have been developing a series of O&M training modules for common devices, based around their products but more widely applicable to other manufactured treatment devices. In this workshop, they will cover some key examples in an hour of learning, followed by an interactive Q&A and quiz session.
Stormwater Asset Transfer Workshop – DIA
Facilitator(s): Phillip Eyles, DIA and Helen Shaw, Beca
The 3 Waters NTU Stormwater workstream has developed a way of categorizing stormwater network assets to help identify those transferring to the Water Services Entities and those staying with Territorial Authorities. We have applied the methodology to available digital asset data across New Zealand, to enable us to quickly identify the core assets for transfer, while flagging those that need discussion between the WSE’s, the Tas, and other agencies.
This session will talk through the current programme for the transfer of stormwater assets and functions, the methodology development and application, and share some preliminary results. Challenges around consistency and assumptions relating to various asset types will be discussed.
This session is designed to be informative and will be of interest to those keen to hear how the reform is progressing, and to understand how the current legislative framework may play out to practical terms.
