Resilient Water Infrastructure Claire Mortimer Manaaki Whenua Landcare Research
CSC Research findings Councils asked for; • ‘More specific information on the effect of stormwater run-off from impervious surfaces’ • ‘Whole-of-life costs and benefits for swales and stormwater collection ponds’
C-CALM CATCHMENT CONTAMINANT ANNUAL LOADS MODEL Existing Research/tools • Body of research on impacts of stormwater run off (Landcare Research, NIWA) • CostNZ; compares relative life-time costs of various stormwater management devices • C-CALM; sub-catchment based stormwater treatment planning model
Existing research cont. • Low Impact Urban Design and Development (LIUDD) • Working with natural systems and minimizing environmental impacts • Integral to broader urban planning • Social, institutional barriers and enablers to technology adoption
Emerging LIUDD Research • Life Cycle Assessment:What are the lifetime costs of green roofs, walls & street trees? • Multiple Ecosystem Service BenefitsWhat are the full suite of benefits (e.g., water supply, public health, biodiversity, amenity values) delivered under various LIUDD options? • OptimisationWhat are the best device designs to achieve different benefits & outcomes? • Scaling up Cost benefits when we scale up? • MonitoringTo what extent is LIUDD cumulatively being taken up in NZ settlements
Hard & soft research needed for new technologies Technical Quantifying impacts of problem Quantifying benefits of technology; Optimizing design for different benefits Policy Assessing relative life cycle costs of new v conventional technology Alignment to plans, regulations Social Community acceptance; social practices, identity Implementation Common construction mistakes Who maintains decentralized infrastructure? Capacity building of planners, engineers, construction companies LIUDD adoption
Research principles for infrastructure • Integrate physical and social science – design performance and uptake • Research and Council staff working in teams • Resilience/adaptability as a design principle for 21st Century infrastructure • Frame infrastructure within broader dynamic urban system and pursue multiple benefits
