IDS Wai (Water) - Pipe Renewal & Replacement Model
Let us help your council work smarter not harder when it comes to planning around Three Waters.
We can guide you through the Three Waters transition using scientific and sound information to determine your replacement profile for your Three Waters National Transition Unit (NTU) capital programme submissions and beyond.
What is IDS-Wai?
IDS-Wai (Pipe Renewal & Replacement Model) is a risk-based forecasting model for potable (drinking) water and wastewater & stormwater piped networks.
By utilising your existing water pipe data (irrespective of its condition) including inventory, condition, performance and financial records, the IDS-Wai modelling outcomes (reports) can help you understand your network's future maintenance and investment needs.
We can provide the evidence you need for not only the 3Waters regulatory requirements (in March and August 2023), but also assurance that you are spending the right money in the right places at the right time long-term.
Benefits of IDS-Wai modelling for you and your community
-
Valuable analytics and solid evidence you need for the Three Waters regulatory framework
-
Evaluate and understand your water asset network’s maintenance and investment needs in more depth
-
Confidently provide the best economic return for your ratepayers and wider stakeholders
-
Provide safe, affordable, and reliable drinking water, and wastewater and stormwater networks/services that meet external regulations, and environmental and cultural expectations.
-
Have confidence in your replacement profile for the next 10, 20 years and beyond
-
Explore the ratio between affordability and cost implications for different risk or service level scenarios
-
Explore the ratio between required investment levels to retain a network’s current value versus how this will impact the pockets of your ratepayers.
Data condition
IDS realise that no council has perfect data - the model can run on existing data and in the process, provide strategic guidance on where to focus future data collection and data improvements.
Our experienced team can work through this with you.
Who has used IDS-Wai?
The modelling tool has been used at several councils to date: Dunedin City Council, testing of Hastings District Council’s network, and more recently, Central Otago District Council and Selwyn District Council.
