Rain's too valuable to go down the drain\r\n

Managed properly, stormwater is a valuable resource that can enhance cities' liveability, sustainability and resilience. We do it by working with local government authorities (LGAs) to improve the health of our waterways, provide opportunities for stormwater reuse and protect people and properties from flooding. So how do we manage stormwater, and how do we redirect it?

雨水太宝贵了,不能流走

如果管理得当,雨水是一种宝贵的资源,可以增强城市的宜居性、可持续性和复原力。为此,我们与当地政府部门(LGAs)合作,改善我们水道的健康状况,为雨水再利用提供机会保护人员和财产免受洪水侵袭。那么,我们如何管理雨水,如何改变它的方向呢?


Our stormwater system
\r\n\r\n

Urban environments are packed with hard surfaces such as roofs, roads and footpaths that prevent rain from soaking into the ground. Stormwater is the water that flows on those surfaces after rain. Often it flows from property drains to street gutters operated by local councils, and these may connect to our large channels, pipes and creeks. This is what forms the stormwater drainage system.

\r\n

Our stormwater network provides services to about 634,530 properties. It consists of:
\r\n

\r\n
    \r\n
  • 73 catchments
  • \r\n
  • 457 kilometres of channels and pipes
  • \r\n
  • over 70 stormwater quality improvement devices.
  • \r\n

我们的雨水系统

城市环境中充斥着坚硬的表面,如屋顶、道路和人行道,这些表面可以防止雨水渗入地面。雨水是雨后流过这些表面的水。通常,水从物业的排水沟流入由地方议会管理的街道排水沟,这些排水沟可能与我们的大型渠道、管道和小溪相连。这就是形成雨水排水系统

我们的雨水网络为约634,530个物业提供服务。它包括:

  • 73年集雨
  • 457公里的水道和管道
  • 超过70个雨水水质改善装置。

Stormwater safety\r\n

Only authorised maintenance crews can safely enter our stormwater system, which includes open channels, drains and underground tunnels. These are dangerous because:

\r\n
    \r\n
  • water can rise quickly and unexpectedly, even when it’s not raining in the immediate area
  • \r\n
  • flowing water is powerful and can knock people over, even when it's shallow
  • \r\n
  • stormwater contains pollutants, including dangerous chemicals and disease-causing bacteria. 
  • \r\n
\r\n"}}" id="ID03" class="cmp-text">

雨水安全

只有获授权的维修人员才能安全进入我们的雨水系统,包括明渠、排水渠和地下隧道。这些是危险的,因为:

  • 即使附近地区没有下雨,水也会出乎意料地迅速上涨
  • 流动的水是强大的,可以把人撞倒,即使它是浅的
  • 雨水含有污染物,包括危险的化学物质和致病细菌。

报告未经授权进入雨水系统的情况
如果你看到任何人进入雨水渠、通道、隧道或维修洞,请通知我们13 20 90, 24/7。我们会对你的联系方式保密,你可能会避免意外或死亡。我们会调查所有关于进入我们雨水系统的报告,并将它们提交给警方或其他当局。


Flooding in Greater Sydney\r\n

Heavy or prolonged rain can cause creeks and coastal rivers to rise quickly. It can take only minutes for waterways to pose a major flood hazard. Fast-moving floodwaters in populated areas are a serious risk to life and property.

\r\n

Flash floods are the most dangerous type of flood, and result from short, extremely intense bursts of rain. They often occur in heavily populated areas with little or no warning. In contrast, rivers in western NSW generally flood slowly, usually taking weeks and months to fully develop. This can lead to major property damage and isolation of entire communities. Floods are Australia’s most costly and predictable natural disaster.

\r\n

This difference in speed and duration of flooding is caused by:

\r\n
    \r\n
  • soil type
  • \r\n
  • storm length and intensity
  • \r\n
  • topography (or landscape)
  • \r\n
  • land use and development (hard surfaces increase run-off speed in urban areas).
  • \r\n
\r\n

We help prevent flooding in many ways.

大悉尼洪水泛滥

大雨或长时间的降雨会导致小溪和沿海河流迅速上涨。只要几分钟,水路就会构成重大洪水威胁。在人口密集地区快速移动的洪水对生命和财产构成严重威胁。

洪水是最危险的洪水类型,是由短暂的、强度极高的暴雨引起的。它们经常发生在人口密集地区,几乎没有预警。相比之下,新南威尔士州西部的河流通常洪水缓慢,通常需要数周或数月才能完全发展。这可能导致重大财产损失和整个社区的孤立。洪水是澳大利亚最昂贵和最可预测的自然灾害。

水浸速度和持续时间的差异是由以下原因造成的:

  • 土壤类型
  • 风暴长度和强度
  • 地形(或景观)
  • 土地利用和开发(坚硬的地表增加了城市地区的径流速度)。

我们在许多方面帮助防止洪水。

Our stormwater assets are located across 23 LGAs in Greater Sydney, and we work closely with these LGAs to reduce the impact of flooding on the community. We also offer our expertise in stormwater catchments outside our areas of responsibility.
\r\n

\r\n

Protecting stormwater assets

\r\n

We protect our stormwater assets so they work as intended. We regularly check the structure and operation of our assets and maintain or renew them. This is a key part of how we manage flooding.

\r\n

Assessing development applications

\r\n

Sydney Water assesses all development applications near our stormwater assets. Sometimes proposed developments can be impacted by flooding or make flood risk worse for others. If this happens, the developer needs to propose alternative designs and consult with LGAs and Sydney Water.

\r\n

Participating in Floodplain Risk Management Committees

\r\n

We participate in Floodplain Risk Management Committees with local councils, communities and other agencies, outlined in the NSW Government Floodplain Development Manual. These committees oversee the preparation of:

\r\n
    \r\n
  • flood study to identify and quantify local flooding
  • \r\n
  • floodplain risk management study to assess the options to address flooding
  • \r\n
  • floodplain risk management plan to prioritise measures that will reduce flooding.
  • \r\n
\r\n

Collaborating with LGAs in Greater Sydney

\r\n

We play an active role in the stormwater industry, and participate in many council and community events to address flooding. We contribute by sharing our knowledge, offering advice and discussing proposed modifications to the stormwater system.

我们的雨水资产分布在大悉尼的23个地区,我们与这些地区密切合作,以减少洪水对社区的影响。我们也提供我们的专业知识,在我们的责任范围以外的雨水集水区。

保护雨水资产

我们保护我们的雨水资产,让它们正常工作。我们定期检查资产的结构和运作,并对其进行维护或更新。这是我们应对洪水的关键部分。

评估开发应用程序

悉尼水务公司评估了我们雨水资产附近的所有开发应用。有时拟议的开发项目可能会受到洪水的影响,或使其他地区的洪水风险更大。如果发生这种情况,开发人员需要提出替代设计,并与LGAs和Sydney Water协商。

参与河漫滩风险管理委员会

我们与地方议会、社区和新南威尔士州政府概述的其他机构一起参加河漫滩风险管理委员会泛洪滩发展手册.这些委员会负责监督:

  • 确定和量化局部洪水的洪水研究
  • 泛洪滩风险管理研究,以评估处理泛洪的方案
  • 漫滩风险管理计划优先采取减少洪水的措施。

与大悉尼地区的lga合作

我们在雨水行业中扮演着积极的角色,并参与了许多委员会和社区活动来解决洪水问题。我们通过分享我们的知识、提供建议和讨论拟议的雨水系统修改来做出贡献。


Stormwater quality\r\n

Stormwater can carry pollution like litter, sediment, grease, oil and metals that are picked up from roads and properties. This pollution affects the quality of our local waterways. We've installed over 70 stormwater quality improvement devices (SQIDs) to help clean stormwater. These include trash racks, sediment traps and litter booms.
\r\n

\r\n

If you're connecting to our stormwater pipes or developing your property, you must meet our stormwater quality targets.

雨水质量

雨水会携带垃圾、沉淀物、油脂、油和金属等污染物,这些都是从道路和物业中收集的。这种污染影响了我们当地水道的质量。我们安装了超过70个雨水水质改善装置,以帮助清洁雨水。这些包括垃圾架、沉淀物陷阱和垃圾栏。

如果您要连接我们的雨水管道或开发您的物业,您必须满足我们的雨水水质指标


Stormwater harvesting\r\n

Stormwater harvesting is the practice of collecting, storing and treating stormwater from urban areas. It's collected from stormwater drains or creeks, rather than roofs, and treated so it’s safe to use as recycled water. Then, it's commonly used to water public parks, gardens, sports fields and golf courses.

\r\n

Benefits of stormwater harvesting are that it:

\r\n
    \r\n
  • reduces the demand for drinking water by replacing it with recycled water produced from stormwater harvesting
  • \r\n
  • reduces stress on urban streams and rivers by capturing some of the pollutants and nutrients that would otherwise enter waterways from stormwater flows
  • \r\n
  • enables users to access an alternative source of water for non-drinking use
  • \r\n
  • increases opportunities for sustainable water management, which is an important consideration in water-sensitive urban design (WSUD) (553KB).
  • \r\n

雨水收集

雨水收集是从城市地区收集、储存和处理雨水的实践。它是从雨水排水沟或小溪中收集的,而不是屋顶,经过处理后可以安全地作为循环水使用。然后,它通常用于水公园花园体育领域而且高尔夫球场

雨水收集的好处是:

  • 用收集雨水产生的循环水取代饮用水,减少对饮用水的需求
  • 通过捕获一些原本会从雨水流进入水道的污染物和营养物质,减少城市溪流和河流的压力
  • 使使用者能够获得非饮用用水的替代水源
  • 增加可持续水资源管理的机会,这是在对水敏感的城市设计(53kb)

你可能想要研究建立你自己的雨水收集计划。

We work with local councils and other agencies to manage stormwater and investigate opportunities for stormwater's collection and reuse. It's one of the many ways the NSW Government is securing Sydney’s water supply for a growing population.

\r\n

There's a lot of advice and assistance available if you want to set up your stormwater harvesting scheme from our stormwater system. Find out more about what you need to do from our fact sheet, Stormwater harvesting (1.5MB). You can also review our Stormwater Harvesting and Re-use Agreement (357KB).
