水源

Our main water sources\r\n

All water comes from the environment and flows through the natural water cycle. People manage this to make sure we have a safe and reliable water supply. Managing water in this way creates the urban water cycle. The urban water cycle takes water from many sources.

我们的主要水源

所有水都来自环境,流过自然水循环。人们对此进行管理,以确保我们有安全可靠的供水。以这种方式管理水城市水周期。城市水上周期从许多来源吸收水。


Catchments
\r\n\r\n

A catchment is an area of land, usually surrounded by mountains or hills, where all rainfall that runs off the land flows to a common point.

\r\n

When rain falls in a catchment, it flows by gravity downhill – either over the surface or under the ground towards the ocean.

\r\n

If the water flows on top of the ground, it's called surface water. If it soaks into the ground by infiltration, it collects in aquifers and becomes groundwater. Surface water and groundwater flow into waterways like creeks and rivers, or can be stored in water bodies like lakes, lagoons and wetlands. This freshwater eventually flows into the ocean where most of the Earth's water is found.

集水区

集水区是一块土地,通常被山脉或山丘所包围,在土地上流出的所有降雨都流向公共点。

当雨水落入集水区时,它会下坡流动 - 无论是在地面还是地面下方朝着海洋。

如果水流在地面顶部,则称为地表水。如果它通过渗透吸收到地面,它将收集含水层并成为地下水。地表水和地下水流入小溪和河流等水道,也可以存放在湖泊,泻湖和湿地等水体中。这种淡水最终流入了地球大部分水的海洋中。

悉尼的大部分饮用水都来自蓝山和南部高地。

The Hawkesbury–Nepean River system is the source of the largest volume of Sydney’s drinking water. This river system includes the Hawkesbury–Nepean River and all the smaller rivers that flow into it. They make up an area called the Hawkesbury–Nepean catchment. This large valley of over 22,000 square kilometres is larger than the whole of Greater Sydney.

\r\n

The land use within a catchment affects the quality and amount of water in a river. It's important that all land use is managed carefully to make sure rivers remain healthy. Managing the impacts of all the activities around a river and its catchment is called total catchment management.

\r\n

WaterNSW protects the health of our drinking water catchments. This ensures a reliable source of quality, fresh water is available for us to filter and supply to the people of Sydney, the Illawarra and the Blue Mountains. Find out more about managing catchments.

Hawkesbury -Nepean River系统是悉尼饮用水中最大量的来源。这条河系统包括霍克斯伯里 - 尼普河和所有流入其中的较小河流。他们组成了一个名为Hawkesbury -Nepean集水区的区域。这个超过22,000平方公里的大山谷比整个大悉尼大。

集水区内的土地利用会影响河流中水的质量和数量。重要的是要仔细管理所有土地利用,以确保河流保持健康。管理河流周围所有活动及其集水区的影响称为全部集水管理。

Dams\r\n

Rain falling in river catchments is currently the main source of Sydney’s drinking water.

\r\n

Dams are built across rivers to catch and store water to give us a more permanent and reliable water supply. Dams store water in an area behind the dam wall. This is often called a storage reservoir.

\r\n

WaterNSW manages and protects drinking water catchments in NSW. Five of these catchments provide the source water for 11 major dams that supply water for Sydney, the Illawarra and the Blue Mountains. 

\r\n

Sydney's dam water is filtered at one of our 9 water filtration plants to make sure it’s of excellent quality, clean and safe to drink.

\r\n

Warragamba Dam is Sydney’s largest dam. It provides about 80% of Greater Sydney's water supply. The dam collects water from the Wollondilly and Coxs river systems and forms Lake Burragorang behind the dam wall.

\r\n

Warragamba Dam is 65 kilometres west of Sydney in a narrow gorge on the Warragamba River. It's the largest urban water supply in Australia and one of the largest domestic water supply dams in the world. It holds 4 times more water than Sydney Harbour when it's full.

\r\n

Some water also comes from smaller dams to the south of Sydney or in the Blue Mountains. These include CataractCordeauxAvon and Nepean dams.

大坝

目前,河流流域降雨是悉尼饮用水的主要来源。

大坝遍布河流以捕捞和储存水,以使我们提供更永久和可靠的供水。大坝将水存储在大坝墙后面的区域。这通常称为存储库。

Waternsw管理并保护新南威尔士州的饮用水集水区。这些集水区中有五个为11个主要水坝提供了源水,这些水坝为悉尼,伊拉瓦拉和蓝山提供了水。

悉尼的大坝水在我们的9个中被过滤水过滤植物以确保其质量优质,干净且安全饮用。

沃拉甘巴大坝是悉尼最大的水坝。它提供了大悉尼供水的约80%。大坝从Wollondilly和Coxs River Systems收集水,并在大坝墙后面形成了Burragorang湖。

沃拉甘巴大坝(Warragamba Dam)在悉尼以西65公里处,位于沃拉甘巴河(Warragamba River)的狭窄峡谷中。它是澳大利亚最大的城市供水,也是世界上最大的国内供水大坝之一。它的水比悉尼港口多4倍。

一些水也来自较小的水坝,到悉尼南部或蓝山。这些包括白内障,,,,山脉,,,,雅芳Nepean大坝。

Dam levels\r\n

Warragamba Dam’s water level rises and falls depending on the amount of:

\r\n
    \r\n
  • rainfall in its catchment
  • \r\n
  • water used by people in Sydney.
  • \r\n
\r\n

Since Warragamba was built in 1960, its lowest dam level was 32.4% on 10 February 2007. This occurred during a drought known as the Millennium Drought, which lasted from 1996 to mid-2010. In 2019–20, we experienced the effects of the worst drought on record.

大坝水平

Warragamba大坝的水位上升并跌落,具体取决于:

  • 流域降雨
  • 悉尼人使用的水。

自Warragamba于1960年建造以来,其最低水坝水平在2007年2月10日为32.4%。千年干旱,从1996年到2010年中期。在2019 - 20年度,我们经历了最严重的干旱对记录的影响。

在干旱期间(2020年1月中旬),沃拉甘巴大坝的容量下降到约42%。


Oceans\r\n

The ocean can be used as a source of drinking water. Unlike rivers and dams, the amount of seawater in oceans is not affected by changing rainfall.

\r\n

Desalination is the process of removing the salt from seawater to produce drinking water. It is a way to make sure people have enough water when:

\r\n
    \r\n
  • countries do not have rivers that are easy to get to
  • \r\n
  • countries are affected by drought
  • \r\n
  • rainfall isn't adequate
  • \r\n
  • populations grow faster than existing water supplies.
  • \r\n
\r\n

In response to the Millennium Drought, the NSW Government commissioned the Sydney Desalination Plant on the coast at Kurnell, between Botany Bay and the Tasman Sea. It can produce 250 million litres a day, which is about 15% of Greater Sydney's drinking water needs. It operates as outlined in the Metropolitan Water Plan.

\r\n

Desalination has provided an extra source of water for Sydney that doesn't rely on rain. It's an important part of the NSW Government's plan to make sure we have enough water for the future.

\r\n

Water from the desalination plant must meet the Australian Drinking Water Guidelines and Sydney Water’s standards.

海洋

海洋可以用作饮用水的来源。与河流和大坝不同,海洋中的海水数量不受变化的影响。

淡化是从海水中除去盐以生产饮用水的过程。这是确保人们在以下情况下有足够的水的一种方法:

  • 国家没有容易到达的河流
  • 国家受到干旱的影响
  • 降雨不足
  • 种群增长的速度比现有的水供应快。

为了回应千年的干旱,新南威尔士州政府委托悉尼淡化厂在植物湾和塔斯曼海之间的库尔内尔海岸。它每天可以生产2.5亿升,约占大悉尼饮用水需求的15%。它按照在大都市水计划

淡化为悉尼提供了额外的水源,不依赖雨水。这是新南威尔士州政府计划的重要组成部分,以确保我们有足够的水为未来。

淡化厂的水必须符合澳大利亚饮用水指南和悉尼水的标准。

Recycled water\r\n

Recycled water is water that's been used before. Recycled water is also another reliable source of water. We take wastewater or stormwater and clean it to a high standard so it can be returned to homes and businesses and safely used again.

\r\n

There are many cities around the world that use recycled water as part of their drinking water supply. Some places you might like to learn more about are PerthSan Diego and Singapore.

Other sources\r\n

In Australia and in many other countries, water is scarce. People have developed many ways to collect and store water. These include groundwater and rainwater tanks.

\r\n

Groundwater

\r\n

Groundwater is water located beneath the Earth's surface. Some rain falling in catchments infiltrates into the ground and is called groundwater.

\r\n

Groundwater collects in aquifers that are the spaces in rocks and between grains of sand and gravel. Groundwater slowly moves through these aquifers and flows into rivers, streams, lakes and wetlands. The top of the groundwater is called the water table.

\r\n

Aquifers can store large quantities of water and can be the main source of water, particularly in dry areas. This groundwater can be used by people who build wells or bores to reach the water under the ground.

\r\n

If groundwater is used in a sustainable way, it can be an important part of a city's water supply system.

其他来源

在澳大利亚和许多其他国家,水很少。人们已经开发了许多收集和存储水的方法。这些包括地下水和雨水罐。

地下水

地下水是位于地球表面下方的水。一些雨水流向地面,被称为地下水。

地下水在含水层中收集,这些含水层是岩石中的空间以及沙子和砾石的颗粒之间。地下水慢慢地穿过这些含水层,然后流入河流,溪流,湖泊和湿地。地下水的顶部称为地下水位。

含水层可以存储大量水,可以是主要水源,尤其是在干燥区域。该地下水可以由建造井或孔的人使用以到达地下的水。

如果以可持续的方式使用地下水,则可能是城市供水系统的重要组成部分。

Rainwater tanks\r\n

Rainwater tanks collect water that you can use in your garden.

\r\n

Rainwater tanks can be a water source for drinking, flushing toilets, washing clothes or watering gardens. However, in urban areas it's usually unsafe to drink tank water.

\r\n

This is due to higher levels of pollution in the atmosphere, which could pollute the tank water. NSW Health recommends that people use their public water supply for drinking and cooking because it's filtered, disinfected and generally fluoridated.

\r\n

After long periods of drought, many people in Greater Sydney installed rainwater tanks. This water is used to water gardens, flush toilets, and helps conserve our drinking water resources. 

\r\n

雨水坦克

雨水罐收集您可以在花园中使用的水。

雨水坦克可以是饮用,冲洗厕所,洗衣服或浇水花园的水源。但是,在城市地区,喝水罐水通常是不安全的。

这是由于大气中污染的水平较高,这可能会污染坦克水。新南威尔士州的Health建议人们将其公共供水用于饮酒和烹饪,因为它已被过滤,消毒和普遍氟化。

经过长时间的干旱,大悉尼的许多人安装了雨水坦克。这种水用于水花园,冲洗厕所,并有助于节省我们的饮用水资源。
