避免废水溢出
Though we do our best to stop wastewater overflows before they happen, we can’t always prevent them. Please stay clear of the area and keep yourself safe. Until the wastewater blockage is cleared and the area cleaned up, any overflow poses a risk to the community and the environment. So, if you see a wastewater overflow, please report it.
\r\n"}}" id="text-ea81a6a756" class="cmp-text">你需要知道的安全知识
尽管我们尽最大努力在废水溢出发生之前阻止它，但我们不能总是阻止它。请远离该区域，并注意自身安全。在污水淤塞和清理地区之前，任何污水溢出都会对社区和环境构成威胁。所以，如果你看到废水溢出，请报告．
当你看到这样的标志时，避开这个区域。
Stay clear of wastewater overflows by obeying our warning signs. It's the most important thing you can do to stay safe.
\r\n- \r\n
- Stay away from areas that are obviously affected by wastewater overflow. \r\n
- Don’t swim or go fishing in an affected waterway. \r\n
- Don’t drink the water from an affected waterway. \r\n
- Pay special attention to children and pets. \r\n
- Keep away from machinery, hosing and other equipment we’re using to clean up. \r\n
- Keep away from overflowing access chambers or maintenance holes. \r\n
按照我们的警告信号做吗
遵守我们的警告标志，远离污水溢出。为了安全，这是你能做的最重要的事。
- 远离明显受废水溢出影响的区域。
- 不要在受影响的水道游泳或钓鱼。
- 不要饮用受污染水道的水。
- 要特别注意孩子和宠物。
- 远离机器，软管和其他我们用来清洁的设备。
- 远离溢出的检修室或检修孔。
Wastewater, or sewage, comes from our sinks, showers and toilets. It is transported through our sewerage pipes for treatment. Wastewater overflows happen when something is in the pipe to cause wastewater blockages. There are 3 common causes:
\r\n- \r\n
- tree roots that find their way into the pipes \r\n
- foreign matter like wet wipes, facial tissues and hygiene products flushed in toilets (anything other than pee, poo and paper), and fats, oils and grease poured into sinks \r\n
- stormwater that overloads the wastewater network during heavy rain. \r\n
The blockage prevents the flow of wastewater, which backs up and can overflow out of a maintenance hole. This can occur anywhere there are wastewater pipes: in bushland, in waterways, in a park, on the street or in your own backyard.
\r\n"}}" id="ID02" class="cmp-text">理解为什么会发生溢出
废水或污水来自我们的水槽、淋浴和厕所。污水经我们的污水管道输送处理。当管道中有什么东西导致废水溢出时就会发生废水堵塞．有3种常见的原因:
- 树根它们会进入管道
- 异物比如湿巾，面巾纸和卫生用品在厕所冲水(除了尿、便便和纸以外的任何东西)，以及倒进水槽的脂肪、油和油脂
- 雨水这会在大雨期间使污水管网超载。
堵塞物阻止了废水的流动，使其倒流并从维护孔溢出。这可能发生在任何有污水管道的地方:在灌木丛中，在水道中，在公园里，在街道上或在你自己的后院。
暴雨是污水溢出的常见原因。
待在路障外，远离溢流物、车辆和重型设备。
It’s important to avoid areas impacted by a sewage overflow and to keep children and pets away from them. Here's why:
\r\n- \r\n
- Sewage contains harmful microorganisms such as bacteria, viruses and protozoa. These can cause illnesses like gastroenteritis if you have direct contact with sewage or surfaces contaminated by sewage. \r\n
- There may be additional danger from heavy equipment and moving vehicles while we do essential repairs. \r\n
Sewage that overflows to the environment can also harm sensitive species of flora and fauna.
\r\n"}}" id="ID03" class="cmp-text">要意识到风险
重要的是要避开污水溢出影响的区域，并让孩子和宠物远离它们。原因如下:
- 污水中含有有害微生物，如细菌，病毒而且原生动物．如果你直接接触污水或被污水污染的表面，就会导致胃肠炎等疾病。
- 可能会有额外的危险重型设备而且行驶车辆在我们做基本维修的时候。
污水溢出到环境中也会伤害敏感的动植物物种。
You can be sure the area is safe when we remove our signs and barricades.
\r\nWe use NATA-accredited labs to sample and test waterways. We test throughout the clean-up, and we continue cleaning until the lab results prove that the site has been effectively cleaned. This can take longer in bushland or natural areas. Our clean-up efforts are regulated by the NSW Environmental Protection Authority (EPA) and NSW Health.
\r\nOnce we’ve physically cleaned the site, and contaminated surfaces are dry and exposed to sunlight, dangerous levels of microorganisms will be gone. The area will be safe to enjoy again.
\r\n"}}" id="ID04" class="cmp-text">安全了我们会通知你的
当我们拆除我们的标志和路障时，你可以确定这个地区是安全的。
我们使用NATA-accredited实验室对水道进行取样和测试我们在整个清理过程中进行测试，并继续清洁，直到实验室结果证明现场已被有效清洁。在丛林或自然地区，这可能需要更长时间。我们的清理工作受到新南威尔士州的监管环境保护署(环保署)而且新南威尔士州卫生．
一旦我们对现场进行了物理清洗，污染的表面变得干燥并暴露在阳光下，危险水平的微生物就会消失。该地区将是安全的，再次享受。
当我们的警告信号消失时，你就会知道它是安全的。
The process we follow to manage wastewater overflow incidents is agreed by regulators:
\r\n"}}" id="ID05" class="cmp-text">我们处理废水溢出的过程
我们处理污水溢出事故的程序已获监管机构同意:
\r\n\r\n
2 A technician goes to the site to verify sewage overflow and assess the impact on both community safety and the environment.
\r\n3 We install containment immediately to stop the overflow from travelling further. We also put up signs and barricades to keep the community informed and safe.
\r\n4 The choke crew clears the blockage in the pipe using a high-pressure water jetter.
\r\n
5 The clean-up crew removes all sewage solids and liquids. It then cleans up the impacted area.
\r\n6 Signs and barricades won't be removed until we've completed important checks. The clean-up leader walks the site to verify the clean-up is complete. Then an environmental specialist takes water samples for laboratory assessment – their lab sample confirms the site is back to its pre-overflow condition.
\r\n7 The wastewater overflow is resolved and the site is back to normal.

2一名技术人员前往现场核实污水溢出情况，并评估其对社区安全和环境的影响。
3.我们立即安装密封装置以阻止溢出物进一步扩散。我们还设置了标志和路障，让社区了解信息和安全。
4扼流阀工作人员使用高压喷水器清除管道中的堵塞。
5清洁人员清除所有固体和液体污水。然后它会清理感染区域。
6在我们完成重要检查之前，标识和路障不会被移除。清理负责人在现场巡视，以确认清理工作已经完成。然后，环境专家采集水样进行实验室评估——他们的实验室样本确认该地点已恢复到溢流前的状态。
7废水溢出问题得到解决，现场恢复正常。
