Panel Discussion

Marlon Bridge

Head of Strategy, National Transition Unit, Three Waters Transition Unit, Department of Internal Affairs

Marlon Bridge is currently working for the Government on the Three Waters Reform Programme within the National Transition Unit, which has responsibility for delivery of the programme.  He is currently on secondment from Watercare, Auckland’s water and wastewater supplier, where he holds the position of Deputy Chief Executive.  Watercare is New Zealand’s largest water and wastewater provider with revenues in excess of $750m per annum on an asset base of $12 Billion. Marlon has been in the Water industry for 16 years in various Executive roles including as Chief Financial Officer and Chief Customer Officer.  He was involved in the 2010 ‘super city’ integration where he was one of three people that led the delivery of the amalgamation of the 6 Councils into the Watercare we know today.  His role in the Three Waters reform programme is as Head of Strategy, responsible for delivery of 4 water service entities by 1 July 2024. There are currently over 70 entities providing three waters services for New Zealand.  The Government’s proposal to reduce this to 4 water service entities is based on scale and what that will provide in terms of efficiencies and affordability into the future.  Ultimately, the objective is to improve the health and wellbeing of New Zealanders.

Operations Lead, National Transition Unit, Three Waters Transition Unit, Department of Internal Affairs

Tim is the Operations Lead in the 3 Waters National Transition Unit (NTU) in the Department of Internal Affairs (DIA). He has worked in and around the water sector for a number of years and was the CEO of Metrowater, the former Auckland City Council water utility, and led that organisation through the super city merger of the Auckland Councils in 2010. For a large part of his career Tim worked in the oil industry, involved in oil refining, supply chain and trading activities across NZ, Australia, the UK and USA for a number of years. Since Metrowater, Tim has been involved in a variety of business consulting and civil contracting work across both the private and public sector. This work includes setting up and then running InfraCore, a contracting CCO business, established by Rotorua Lakes Council, providing operations and maintenance services in the three waters, parks and refuse sectors. Tim’s role in the NTU is focused on transitioning the existing 3 waters operational activities of Councils into the new water entities being formed by the 3 waters reforms. This includes responsibility for leading the work to transition current trade waste arrangements into the new entities. 

Starting afresh with Trade Waste

A time to discuss and present ideas on how the operation and regulation of Trade Waste could develop under the 4 Entities of the 3 Waters Reforms. This is a once in a lifetime opportunity to be involved in a process that will change how water is managed for the future of all New Zealander’s and the environment we live in.


Keynote Speakers

Tom Bamford

Fonterra

Tom is a Principal Environmental Engineer with Fonterra’s Environmental Technical Team.  He has been with Fonterra for 29 years working on loss reduction, water minimisation and water reuse in manufacturing plants and treatment of wastewater from the companies 27 manufacturing sites.  Recent projects have focussed on two areas

  1. Technical support for wastewater treatment and discharge reconsenting at Hautapu and Reporoa, including leading the development of water use and wastewater treatment strategies and assessment of alternative wastewater treatment technologies.

  2. Providing a technical overview to support the design and construction of new and upgraded wastewater treatment plants as the sites wastewater discharge resource consents are renewed.

Tom leads the technology strategy for future capital investment for wastewater treatment at Fonterra’s NZ manufacturing sites.

& Vanessa Mitchell

Wastewater Programme Manager, Fonterra

Vanessa is a Programme Manager in Fonterra’s Portfolio Management Office, for the Wastewater Programme which includes consenting through to delivery.

With a chemical engineering background and having worked in Fonterra from product development and commissioning through to project management and capital projects, the last 10 years focus has been on major capital investments for Fonterra. This included programme management for the Wastewater and Stormwater upgrade at Edgecumbe.

Since that time, Vanessa has led the strategy development for the approach to capital investment and long-term planning for wastewater treatment at Fonterra’s NZ manufacturing sites

Addressing the Challenge of Wastewater Treatment for Fonterra

Fonterra has 27 manufacturing sites, with 23 of the sites managing the treatment and discharge of  wastewater. The treatment systems range from irrigation to Fonterra or 3rd party owned farms to biological treatment before river discharge, utilising several other technologies and combinations to meet individual site requirements. 

Many of these sites are in the reconsenting process. Fonterra is committed to the significant capital investment required to upgrade existing treatment plants or to build new treatment systems that will improve existing wastewater management and operational robustness in order to reduce environmental effects and meet environmental regulatory requirements.

The adopted approach ensures that the most appropriate treatment systems, treating the optimum wastewater volume and load, are consented and built to meet the sites manufacturing requirements.   

This approach starts during the consent renewal phase with development of a water and wastewater strategy that includes a robust assessment of alternative wastewater treatment technologies.  This includes an optimisation phase and an assessment of technologies during the design and construction phase.

Talk: The public health case for Three Waters reforms 

Public discourse on the Three Waters reforms has been dominated by anti-co-governance rhetoric and concerns around privatisation. This debate has drowned out the fundamental problem statement justifying the reforms. Primarily that the management of drinking water resources is currently inadequate to protect public health and promote health equity. The talk covers the current burden of water-borne disease in Aotearoa, potential public health issues associated with emerging threats and highlight weaknesses in drinking water management.

Breakout Session Speakers

Caitlin Egan

Environmental Compliance Officer, Napier City Council

Caitlin (or Caity) has been working as an Environmental Compliance Officer at Napier City Council for nearly 4 years. Originally from the UK with a background in Chemistry, Caitlin worked in the energy industry in Australia before moving to Napier to enjoy the easy life in Hawke’s Bay. She is passionate about what she does mostly because of how much time she spends submerged in the Ocean, so has good reasons to want it clean, and believes education is the most important tool to initiate positive change.

Topic: The role of Science Communication in Three Waters and Environmental Management

There appears to be a gap in simple and effective science communication in Three Waters, which all industry players could have a role in filling, to enable a good knowledge base amongst the general public and key stakeholders. Understanding the science behind the Three Waters industry; what it is, why it’s important, what issues it faces and how it could be improved, leads to more effective decision-making and ability to initiate positive change. It can provide tools to prevent misinformation from spreading and becoming a threat to the action that is needed, as well as increase compliance with better understanding of the reasons for rules or restrictions.

To be most effective, science communication should come from the subject matter experts directly, and focus on the science behind key concepts, or the ‘why’ behind the ‘what’. It can be creative and inclusive, relevant to individual areas across Aoteoroa with unique environments, and incorporate kaupapa of the mana whenua. Material should be in a format that is easy to digest, interesting, and shared through a variety of channels to achieve maximum engagement.


Jared Hansen

Trade Waste Consultant and Sampling Technician, BPO

Born and raised within the Waikato, his childhood obsession with dinosaurs might have led you to think he would become a palaeontologist; Jared always had an interest in the natural world.  This would lead him to obtaining a BSc.(Biology) from the University of Waikato and a sense for all manner of things considered nerdy and slightly esoteric, from the tiny to the immense. Jared has spent 20ish years in the water and wastewater industry, with beginnings in the Hamilton WWTP laboratory, water and waste-water treatment operations and then trade waste officer for Waipa DC before joining BPO. With varied work in field monitoring, trade waste sampling and reporting as well as consulting on trade waste applications and improvements, he is also happily found in gumboots, gloves and overalls assisting peers in BPO group projects, H&S permits for confined space, and avoiding the unimaginable cosmic horrors lurking within the unending tunnels which lie unfathomably beneath our feet. And occasionally, when the stars align, he enjoys work on TV and film sets as a background extra (such as Epic NPC Man, Ash vs Evil dead, Letter for the King, and a Bud Knight superbowl commercial).

Topic: Inside the wretched scribblings from the lab: A beginner’s guide to interpreting trade waste results 

Have you ever got a trade waste monitoring report without sufficient context and all you can see is a bunch of numbers with some arcane looking headings and units? Was this scribed in a tongue so indescribably alien you are left wondering if what you’re looking at was even dreamed of in this reality? pH, TSS, cBOD5, COD, TKN, TP and OAG. (And all the rest.)  These all mean something beyond plugging them into the formula for trade waste charges and without sufficient detail their real value can be overlooked. This summary, this mere snapshot is twisting tale of a process or processes and what impact that might have on your waste-water network and treatment plant assets and tell you the whispered secrets of its source. In this discussion, I will attempt to prepare you to delve into the maddening realm of results interpretation, to untangle a skein of information and weave a mantle of understanding from the data before you. 


Stephan Heubeck

Senior Process Engineer, BPO

Stephan Heubeck is a Senior Process Engineer with BPO, based in Hamilton. He has an Agricultural Science degree from the University of Applied Science Weihenstephan – Triesdorf in Germany as well as a Masters in Environmental Engineering from Massey University / Palmerston North. Stephan has 20 years practical and theoretical experience in researching, planning, building, operating and optimizing industrial and municipal wastewater treatment systems, as well as anaerobic digestion systems for agricultural and industrial wastes. Stephan’s work scope has been broad, encompassing a wide range of high-tech and low-tech waste treatment configurations, as well as associated areas and processes, ranging from AD substrate logistics to biogas purification and from wastewater nutrient recycling to optimising the Greenhouse Gas impact of waste treatment systems. Beyond a range of scientific publications, Stephan has over the years contributed to and co-authored numerous guidelines and regulatory documents pertaining to waste management and GHG emissions in New Zealand and Australia. Stephan is a member of the Bioenergy Association of NZ (BANZ), the BANZ Biogas Interest Group (BIG), the Sustainable Energy Forum (SEF) Inc. and Methanet/NZOnet - the MPI scientific advisory group for the agricultural sections of the NZ GHG inventory. Stephan’s overarching goal is to help establish fit-for-purpose and future-proof waste and wastewater management systems throughout New Zealand, that follow closed loop recycling principles, maximise co-benefits, help to reduced fossil fuel use and contribute to the sustainability goals of municipalities, industry, agricultural and the whole country. 


Topic:
 
Overlooked GHG emissions from waste treatment 

This will be part review of which GHG emission we are capturing in the NZ inventory, where there are idiosyncrasies and what could be done better to accurately tally up these emissions, and most importantly how the waste sector may have to deal with these emissions going forward, for example could we capture N2O from denitrification? Will sludge composting increase emissions vs landfilling, and would everything have to be anaerobically digested to really make progress on the GHG emission front?


Joint Presentation Indran Pillay & Mike Sahayam

Topic: Mitigating Stormwater from Tradewaste Sites into the Sewer Network

Stormwater Ingress occurs much too often without consideration from Industrial sites into its impact on the sewer network and the final receiving waters in flood conditions.  A robust management plan on site would lead to reduced, recycled or reused stormwater in process applications rather than being discharged into sewer networks as contaminated stormwater.

Tauranga City Council Tradewaste team is working with Tradewaste industries in the city to mitigate stormwater ingress and this paper discusses the proposals it has taken to industries. We will look at few case studies of how these initiatives have resulted in improved management of stormwater onsite.


Indran Pillay

Trade Waste Specialist, Tauranga City Council 

Indran has been with TCC for the past 3 years, employed as a Trade Waste Specialist.  Originally from South Africa, Indran and his family emigrated to Aotearoa 3.5 years ago. He has 20 some odd years’ experience in the industry, having worked as a WWTP operator, Sampling Officer, Trade Effluent Technician and presently a Trade Waste Specialist. Work experience in the industry included operating extended aeration and biological nutrient removal WWTP’s, sampling and monitoring potable water, wastewater, rivers, dams, boreholes, and landfill leachate. Industrial trade waste experience included working with and monitoring Aluminium smelter/processing plant, Leather tanneries, Vegetable oil refineries, Paper and Pulp industries, electroplating and Food & beverage manufacturing industry. He has a postgraduate diploma in Environmental Engineering from the University of KwaZulu Natal. Interests are wide and varied and include lots of sport, tinkering with cars and motorbikes, woodworking, worm farms, plant growth towers.

Mike has been with TCC for the past 1 year, in the middle of covid-19 he left the safety of Palmerston North where he had been a Trade Waste Officer for over 18 years. Moving to Tauranga has been to enjoy the beaches and leave the wind behind.  Prior to working for PNCC Mike worked for Massey University for 16 years as a Technician and Tutor in the Institute of Technology and Engineering. Mike’ teaching and research interest has been on meat science and making and drinking wine for health. Interests are sports especially football in particular Liverpool FC and a student of theology.


Steve Shaw

General Manager, MacTrap Ltd

Steve trained in Industrial Instrumentation and Process Control which resulted in a broad engineering background including electronic, pneumatic, and software controlled processes. He worked in Pulp and Paper and Petrochemical industries before becoming involved in the associated technologies of Information Technology and Telecommunications. More recently Steve was resident in the USA and was responsible for the International Business Development of a NZ developed SaaS product. After returning from the USA Steve found his way back into an engineering aligned field with the purchase of Mactrap in 2020.

Topic: From Telecommunications to Grease Traps 

It’s been two years since Steve and Kay Shaw embarked upon their Mactrap journey. They left the world of IT&T and the sunny Silicon Valley of San Jose, California, and returned to the sleepy town of Katikati in the Bay of Plenty to manufacture wastewater separation systems. They’ve learnt an awful lot in that time. This session describes those learnings: • There is a lot more to the industry than they thought • Council wastewater networks are not created equal • End users are (mostly) unwillingly ignorant • Customer success is everyone’s success • Listening leads to innovation • Revealed : the potential of a low/no touch, under-bench passive trap with smarts Mactrap specialises in the design, manufacture, and distribution of wastewater separation systems and associated pumping solutions. 


Gary Soper

Trade Waste Officer, New Plymouth City Council


I have been involved in the Waste Water industry for 36 years. Over that period I had gained a vast knowledge of pumping stations, waste water treatment and trade waste. I have worked in several locations of the South Island and in New Plymouth.  The past 21 years have been with New Plymouth District Council and the last 13 years have been as the Trade Waste Officer. During that period the number of consents has increased from 47 to the current 118 consented companies. This excludes most premises which have grease traps. We do monitor grease trap clean outs in Taranaki and for the worst managed systems we do take enforcement steps.

The position is satisfying as it involves the complete spectrum from consenting and managing, sampling, investigation and the financial management. My strength is working with customers to find solutions which are to the advantage of both the Council and the Customer. 

Topic: Random Foaming Events Investigated in New Plymouth 

Working within the constraints of supply issues, a company which blends and sells liquid fertiliser throughout NZ found itself with escalating costs associated with buying IBC’s. Their solution to the constraint was to purchase less desirable IBC’s. The company did not have good internal processes in place. Added to this issue, a staff member modified equipment which had serious ramifications.

This paper deals with:

1. The investigation related to foaming within the sewerage system

2. The collaboration with the Taranaki Regional Council

3. Failure of the business to consider the implication of their action on the environment and the
    sewerage system

4. Discharging a product into the sewerage system which was likely to foam

5. Enforcement action and penalties associated with discharging a product to the sewer and into
    the environment which was likely to foam


Fiona Sutton

Water Services Manager, CoLab Water Services

Fiona Sutton is the Co-Lab Water Services Manager.  She is a qualified lawyer and has worked in local government for over 17 years in various regulatory based roles including resource management, animal control and more recently three waters.  She currently leads a team of 28 staff delivering sampling & analysis, trade waste and drinking water education services to 9 Councils across the Waikato.

Topic: Trade Waste Across Boundaries 

Fiona with the support of some of her Co-Lab Trade Waste team will talk to you about the successes and learnings of commencing service delivery for 7 new Councils with 7 different bylaws.  We will talk about the similarities and the differences and how we are able to effectively share our learnings.  We have found that while each Council approaches trade waste slightly differently because we all have the same outcome in common, the differences are not insurmountable.  From changing templates and processes to educating new trade waste customers the Co-Lab Trade Waste team have done it all in the past 12 months.
