避免废水溢出

What you need to know to stay safe\r\n

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.

您需要知道的要保持安全

尽管我们会尽力阻止废水在发生之前溢出,但我们不能总是阻止它们。请远离该地区并确保自己的安全。在清除废水阻塞并清理区域之前,任何溢出都会给社区和环境带来风险。因此,如果您看到废水溢出,请报告它


当您看到这样的标志时,请避开该区域。

Do what our warning signs say\r\n

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

做我们的警告信号

通过遵守我们的警告信号,请避免废水溢出。这是保持安全的最重要的事情。

  • 远离显然受废水溢出影响的区域。
  • 不要在受影响的水道上游泳或去钓鱼。
  • 不要从受影响的水道上喝水。
  • 特别注意儿童和宠物。
  • 远离我们用来清理的机械,毛绒和其他设备。
  • 避免溢出的访问室或维护孔。

Understand why overflows happen \r\n

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
\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.

了解为什么溢出发生

废水或污水来自我们的水槽,淋浴和厕所。它通过我们的下水道管运输进行治疗。当管道中有东西引起的东西时,废水溢出就会发生废水阻塞。有3个常见原因:

  • 树根那是他们进入管道的路
  • 异物像湿湿巾,面部组织和卫生产品冲洗厕所(除了小便,便便和纸)以及脂肪,油脂和油脂倒入水槽中
  • 雨水这使大雨期间的废水网络超载。

阻塞阻止了废水的流动,​​该废水会向后备份并可以从维护孔中溢出。这可能发生在有废水管道的任何地方:在丛林,在水道,公园,街道上或您自己的后院。

大雨是污水溢出的常见原因。

一名悉尼居民报告说,一项16,000美元的管道账单可以修理其家中的下水道。阻塞是由冲洗湿湿巾引起的。


远离路障,远离溢出,车辆和重型设备。

Be aware of the risks\r\n

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
\r\n

Sewage that overflows to the environment can also harm sensitive species of flora and fauna.

注意风险

重要的是要避免受到污水溢出影响的区域,并使儿童和宠物远离它们。为什么:

  • 污水包含有害的微生物,例如细菌,,,,病毒原生动物。如果您与污水或被污水污染的表面直接接触,这些疾病可能会引起诸如胃肠炎之类的疾病。
  • 可能还有其他危险重型设备移动车辆虽然我们进行基本的维修。

溢出环境的污水也会损害动植物的敏感物种。


We'll let you know when it's safe\r\n

You can be sure the area is safe when we remove our signs and barricades.

\r\n

We 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\n

Once 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.

我们会在安全的时候通知您

当我们删除标志和路障时,您可以确定该区域是安全的。

我们用NATA认可的实验室采样和测试水道。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该站点已有效清洁。这可能需要更长的时间在丛林或自然地区。我们的清理工作受新南威尔士州的监管环境保护局(EPA)新南威尔士州健康

一旦我们对现场进行了物理清洁,并且被污染的表面干燥并暴露于阳光下,危险的微生物将消失。该区域将是安全的。

当我们的警告信号消失时,您会知道它是安全的。


Our process to manage wastewater overflows\r\n

The process we follow to manage wastewater overflow incidents is agreed by regulators:

\r\n"}}" id="ID05" class="cmp-text">

我们管理废水溢出的过程

监管机构同意管理废水溢流事件的过程:

1  The sewage overflow is reported to Sydney Water.
\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\n

3  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\n

4  The choke crew clears the blockage in the pipe using a high-pressure water jetter.
\r\n

\r\n

5  The clean-up crew removes all sewage solids and liquids. It then cleans up the impacted area.

\r\n

6  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\n

7  The wastewater overflow is resolved and the site is back to normal.

1据报道,污水溢流到悉尼水。

2一名技术人员前往现场以验证污水溢出并评估对社区安全和环境的影响。

3我们立即安装遏制,以阻止溢出进一步旅行。我们还提出了标志和路障,以保持社区知情和安全。

4窒息人员使用高压水上喷气机清除管道中的阻塞。

5清理工作人员清除了所有污水和液体。然后,它清理了受影响区域。

6在我们完成重要的检查之前,不会删除标志和路障。清理领导者沿着网站验证清理工作已完成。然后,环境专家将水样品进行实验室评估 - 他们的实验室样本确认该地点又回到了遍布溢流状态。

7废水溢出已解决,该地点恢复正常。
