Pipe Renewals Guidelines

The Evidence Based Investment Decision Making for 3 Water Pipe Network Programme (Pipe Renewals Guidelines Programme) initiated by Quake Centre, IPWEA and Water New Zealand (Water NZ) will develop guidance documents and tools to assist New Zealand’s water organisations to make nationally consistent, evidenced-based decisions relating to the management and renewal of their 3 Water Pipe Networks. The programme covers inspection, maintenance and renewal strategies for pipework in potable water, wastewater and stormwater systems. The tools and guidance documents developed through these initiatives will form a framework that can be used in conjunction with the International Infrastructure Management Manual (IIMM) and the New Zealand Asset Metadata Standards project to implement advanced asset management processes to produce investment strategies that optimise cost, risk and level of service. They will enable organisations to assess the implications of adopting alternative investment strategies and select the strategy that best suits the needs of their community.

This programme of work has been broken down 47 separate projects which will be staged over the coming years as resources allow.
