Wastewater systems provide a critical service to society, and their vulnerability to the impacts of climate change. places the health and sanitation of many communities at risk. The impacts of climate change on wastewater systems are numerous and can lead to wide ranging implications over changing timescales. This paper considers the significance of the impacts and implications, how they will be distributed across different groups, how they will manifest in different contexts and locations, and conclude by proposing a range of guiding principles for local government decision makers.

The research firstly considered direct climate-related impacts on a range of wastewater system elements (including reticulated wastewater systems, on-site wastewater systems and treatment plants), in both urban and peri-urban settings in New Zealand. The impacts identified for each aspect of the wastewater network were found to fit within three broad impact themes; nuisance flooding spills and odour, water quality deterioration due to increased uncontrolled discharges and damage to infrastructure.

The research shows that the immediate and long-term implications resulting from these impacts are likely to be experienced widely across the social, cultural, environmental and economic domains. Examples include loss and damage to assets - leading to disruption to communities, water quality deterioration with consequential social, environmental, economic and cultural effects, public health risks, and economic costs related to damages, foregone production and insurance. Cultural implications are of particular importance in a New Zealand context, given the strong connection of Māori to the environment and water.

废水系统为社会及其对气候变化的影响的脆弱性提供了关键服务。使许多社区的健康和卫生处于危险之中。气候变化对废水系统的影响是多种多样的，并且可以随着时间尺度的变化而产生广泛的影响。本文考虑了影响和含义的重要性，如何将其分布在不同的群体中，如何在不同的背景和位置体现出来，并通过为地方政府决策者提出了一系列指导原则进行了总结。

该研究首先考虑了在新西兰的城市和郊区环境中，与气候有关的一系列废水系统要素（包括网状废水系统，现场废水系统和处理厂）的直接影响。发现针对废水网络各个方面确定的影响符合三个广泛的影响主题：令人讨厌的洪水溢出物和异味，由于无法控制的排放量增加和基础设施损坏而导致水质恶化。

研究表明，这些影响所带来的直接和长期影响很可能在社会，文化，环境和经济领域得到广泛体验。这样的例子包括资产的损失和破坏-导致社区破坏，水质恶化以及随之而来的社会，环境，经济和文化影响，公共卫生风险以及与破坏，放弃生产和保险有关的经济成本。鉴于毛利人与环境和水的紧密联系，在新西兰背景下，文化影响尤为重要。
