Reference Group Meeting 5 5 February 2019
Reference Group Agenda New member introductions Sharing Opportunity (What I have learnt, and plan to contribute) Recap – Solution Reminder/ BPOS Alignment Survey Results Presentation Wastewater Strategy Land Use Discussion Combining and Staging What does affordability look like Criteria v Option – Concept to Solution
New members Etu Araipu (Grey Power) Simon White (Otane Farmer) *Maybe* Marge Hape (Taiwhenua) JB Smith (Hapu) *Maybe* Ricky Carnie (Business/ Trade Waste – Triple NNZ Casings)
What we know and what we have learnt What I know • What is in wastewater • River discharge • Land discharge • How do we balance other views • What is the process to select an option • What are the most important considerations for me What don’t I know and want to know • What are the most important considerations for my community How do we make sure what we are doing is what the community wants
What are we trying to determine Are we looking for an option? Are we looking for a solution that has options? How do we balance what we want with what the community wants? How do we balance affordability?
Our Vision Our effluent is treated in a sustainable way that creates a resource, protects our environment and continues to do so for generations to come

Wastewater Strategy What’s a strategy? How does it differ from what we have done? What is its benefit?
