Foreword

Water is a precious resource and necessity sustaining life on earth. Yet, as a valuable resource, only 2.5% of the Earth’s water is freshwater, among which only 1% out of the 2.5% is easily accessible. With melting of glaciers induced by climate change and contamination caused by human activities, our freshwater resources are being severely jeopardized. The growing population and economic activities also lead to an increased demand on freshwater. At the same time, climate change will result in more frequent occurrence of extreme drought.

Hong Kong is a small city with dense population. In the absence of natural lakes, rivers, or groundwater, Hong Kong has limited water resource. Even though the impoundment of rainwater in local reservoirs, water imported from Dongjiang and seawater flushing system have ensured a reliable supply of freshwater in Hong Kong, water conservation and proper water resource management are crucial to ensure sustainable water supply in Hong Kong.

Water Supplies Department has set priority in educating the young generation about water conservation. A variety of activities including school roadshow, school‐based water audits, water conservation ambassador competitions, visits to Water Resources Education Centre and Water Treatment Works are being organized. “Cherish Water Campus” Integrated Education Programme was first launched in the 2015/16 school year for primary

schools. To further our effort, we have extended the programme to the pre‐primary level.

“Water does not come free from a tap”, every drop of water we consume requires a series of hard work. As a result, water conservation is not just a virtue but a civic responsibility of our society. The concerted effort of the government, schools, teachers, parents and their children, as well as other stakeholders are required to build Hong Kong a water smart city. We hope this programme can instil the importance of water conservation amongst pre‐school students, as well as strengthening the knowledge about cherishing water amongst teachers and parents. Let everyone become an environmental water conservation expert like Water Save Dave.

Introduction

Programme Background

Water Supplies Department (WSD) has been promoting water conservation to the public through various channels. WSD launched the “Cherish Water Campus” Integrated Education

Programme (IEP) to primary schools in the 2015/16 school year. It aims to enhance students’ knowledge of the protection of water resources and the global problem of water resources, to encourage them to adopt water conservation practices at school and at home, and to spread the water‐saving message to their peers, family and the community.

To further extend IEP to pre‐primary levels, WSD launched the “Cherish Water Campus” Integrated Education Programme – Kindergarten. It is hoped that kindergarten teachers can enhance children’s understanding of water and cultivate water‐saving habits among them

with the help of the teaching kits including the Storybook, the Activity Book and the Teacher

Resource Book.

Objectives

To educate and help children develop water‐saving habits in daily life and to improve children’s basic understanding of water related concepts

To encourage children to share their water‐saving tips with their family and friends

To enhance kindergarten teachers’ knowledge about water resources and water conservation so that kindergartens can promote water education continuously and actively

To facilitate a smooth transition to IEP for primary schools

To introduce WSD’s mascot “Water Save Dave” to children and build a connection between them

Targets

Children aged between 5 and 6, their teachers and parents.

Principles of the Teaching Kit

This teaching kit is designed for children aged between 5 and 6. It aims at explaining water‐saving habits and simple concepts about water to children in the form of a story, spreading the message of water conservation. Children can also acquire the knowledge about water, through class activities, in order to introduce the idea of water conservation culture to pre‐primary levels.

Content and Features

The teaching kit is based on the storybook “The Adventure of Water Save Dave and the Kingdom of Cando”, which follows Water Save Dave’s adventure in the Kingdom of Cando. The way Water Save Dave teaches the animals to conserve water can show children that water is a shared but limited resource and should be conserved in our daily life.

The teaching kit also includes the Activity Book that suggests a variety of activities and accords with the six learning areas of the “Kindergarten Education Curriculum Guide” (2017). Teachers can promote the awareness of water‐saving among children through activities on topics like the use of water, properties of water and water conservation.

The Teacher Resource Book aims at enhancing teachers’ knowledge about water resources and supporting teachers in inculcating such knowledge in children.

Teacher’s Manual

It is suggested that teachers introduce the preciousness of water and proper water use with the story of “The Adventure of Water Save Dave and the Kingdom of Cando” which arouses children’s motivation and curiosity. Teachers can then move on to a more in‐depth discussion from different angles. According to the needs and the classroom setting, teachers can organize appropriate activities with reference to the Activity Book so as to lead the children to share, discuss or conduct the experiments, and to think about water conservation and the properties of water from different perspectives. With the information on different topics in the Teacher Resource Book, teachers can enhance children’s knowledge of water resources and encourage them to share the water‐saving habits with their family members and friends.

Humans and Water

Relationship between Humans and Water

All living things depend on water for survival. In nature, water moves in a cycle around the Earth by the physical processes of evaporation, condensation and precipitation, supplying living things with freshwater and lowering the temperature of the Earth’s surface.

Besides, about 70% of the mass of the human body is made up of water, which is involved in many reactions like blood circulation, digestion and excretion. Without water, humans cannot survive. Water also plays an important part in urban development that all of the four ancient civilizations grew up along large river valleys.

Uses of Water

Humans have been making use of water for many purposes since ancient times. Apart from drinking, we use water to cook, to clean our houses and to take a shower in our daily lives. In production processes, water is used in agriculture, aquaculture, animal husbandry, textile industry, heavy industry, sewage treatment and electricity generation. In nature, water can regulate the Earth’s temperature, clean the atmosphere as raindrops, change the landscape as rivers and protect marine life from UV radiation.

Water, Food and Energy

Water, food and energy are interconnected. It takes water to produce food and energy, while treating and distributing water also require energy. As responsible citizens of the global village, we should do what we can to ensure sustainable use of water resources. We can reduce water consumption by making smart choices in purchase and wisely consuming food/products that require less water for production.

Tips from Water Save Dave:

You can save energy by saving water and also save water by saving energy. Apart from these,

be food wise to be water wise!

Daily Water Consumption

The United Nations reckons that “between 50 and 100 litres of water per person per day are

needed to ensure most basic needs”. However, the domestic per capita water consumption of Hong Kong is 130 litres per day (flushing water excluded), which is higher than the world average of 110 litres. The average domestic freshwater consumption per person per day in nearby cities:

Macau 157 Litres

Shanghai 118 Litres

Singapore 148 Litres

Virtual Water

We need water for cleansing and cooking in our daily life. However, the amount of water we consume is far more than that we see because a large quantity of water is hidden. The amount of water that is embedded in food or other products needed for their production is known as virtual water.

For example, to produce 1 kilogram of wheat, we need about 1,000 litres of water, i.e. the virtual water consumption for the production of this kilogram of wheat is 1,000 litres.

How much water does it take to produce 1 kilogram of beef?

1. Water for grains (about 6.5 kg of grains, e.g.

oats)

Producing this volume of feed requires about 15,300 litres of water on average 2. Water for roughages

(about 36 kg of roughages,

e.g. pasture, dry hay)

3. Water for drinking Drinking and servicing require about 155 litres of water on average

4. Water for servicing

The amount of virtual water required for producing 1 kilogram of beef is about 15,455 litres

of water.

How much water have you consumed in your lunch?

Take “rice with tomatoes and pork” as an example:

Ingredients Virtual Water Consumption (litres)

Rice (75g) 181

2 Tomatoes (200g) 57

Pork (100g) 610

Eggs (100g) 327

Onion (75g) 20

Cheese (20g) 101

Tomato Sauce (30g) 16

Take 1 cup of lemon tea as an example:

Ingredients Virtual Water Consumption (litres)

Lemon (17.5g) 11

Tea (6.5g) 58

Total Virtual Water Consumption: 1,381 L

Properties of Water

The Three States of Water

Water is colourless, tasteless and nontoxic. It exists in three different states, namely, solid, liquid and gas. It changes between these three forms based upon the surrounding temperature. Water freezes into ice, its solid form, at temperatures lower than 0℃; it evaporates into steam, its gas form, at temperatures higher than 100℃.

Water Cycle

In Hong Kong, it is simple to turn on the tap and fill a glass with clean potable water. However, do you know that the glass of water has travelled a long way before it reaches you and myriads of things have to be done to make this happen? Water does not come free from a tap, it does not come easily:

1. Heat from the sun drives water out of the sea, lakes, rivers, trees and all other living things, which then evaporates as water vapour.

2. Water vapour rises into the air where cooler temperatures cause it to condense into clouds.

3. The water falls from the sky in the form of rain.

4. Rainwater falls into the rivers or onto catchment areas and then flows into reservoirs.

5. Water in the reservoirs is delivered to water treatment works and the treated water will be sent to the service reservoirs.

6. Water stored in the service reservoirs is transported to the taps of our homes in every part of Hong Kong through the distribution network.

7. Used water is sent to sewage treatment works for treatment before being discharged into the sea or recycled.

8. Heat from the sun drives water out of the sea again...This is how the water cycle works.

Water Resources on Earth

Precious Freshwater

Freshwater is a precious and scarce natural resource. Freshwater accounts for only 2.5% of the Earth’s water, 70% of which is in the form of glaciers and snow caps in the poles and mountainous regions. The rest is salt water which is not potable. In a nutshell, suppose Earth’s water is represented by 100 cups, only 2.5 cups are freshwater. Therefore, freshwater is very precious.

Global Distribution of Water Resources

More than half of the world’s freshwater resources are contained in 9 countries: Canada, the United States, Colombia, Brazil, Russia, China, India, Indonesia and the Democratic Republic of Congo. It is not difficult to imagine the scarcity of freshwater resources in other countries. Even in more water‐ abundant countries, water resources may not be evenly distributed among different regions. For instance, some regions in the United States are still facing serious problems of water scarcity.

Water Resources in Hong Kong

Three‐Pronged Water Supply System

Currently, Hong Kong has a 3‐pronged water supply system, comprising rainwater from local catchments, imported water from Dongjiang in Guangdong and seawater for toilet flushing.

With these three water sources, Hong Kong has been enjoying reliable water supply over the years.

1. Local Yield

About one third of Hong Kong’s land is designated as water gathering grounds and most of them overlap with Country Parks. The local yield accounts for only 20% to 30% of Hong Kong’s total consumption. The amount of local yield is affected by the fluctuations in yearly rainfall totals.

2. Dongjiang Water

Dongjiang water, which now provides about 70% to 80% of our total consumption, filling the gap arising from our inadequate local yield. Hong Kong people are actually consuming the water sources of nearby regions. The supply of Dongjiang water is not inexhaustible and it is transported to Hong Kong with strenuous efforts. Therefore, water conservation does not only protect the water resources of nearby regions, but also saves the energy and cost of transporting water.

3. Seawater for Flushing

Surrounded by sea on three sides, Hong Kong has been using seawater for flushing since the late 1950’s.

Up till now, Hong Kong is one of the few places extensively applying seawater for flushing, effectively reducing the freshwater consumption by as much as 20%. We will continue to extend the use of seawater for flushing to reduce freshwater demand. In 2015, the WSD

successfully expanded Hong Kong’s seawater supply coverage to 85% of the population. At present, seawater is available to buildings in Northwest New Territories and Pok Fu Lam for flushing. When the seawater supply system is fully implemented in the expanded zones, a total amount of 20 million cubic metres of freshwater will be conserved every year.

The seawater is firstly screened by strainers to remove sizeable particles, and then disinfected with chlorine or hypochlorite before being pumped to service reservoirs and for distribution to consumers. The sea water supply system is completely separated from the potable water supply system.

Water Treatment Process

Raw (untreated) water is treated before being supplied to the public:

Raw water is pre‐treated by dosing with chemicals, e.g. alum. Mixing and flocculation

allow suspended solids to come together to form bigger particles and settle to the bottom of the clarifiers as sludge.

The sludge settled to the bottom of the clarifiers is collected and pressed into sludge cakes before being disposed.

The clarified water then flows through filters of sand overlaid with anthracite to remove more fine suspended particles.

Three useful substances are added to the filtered water:

Hydrated lime: to neutralize the acidity of alum and adjust the alkalinity Chlorine: to disinfect the filtered water

Fluoride: to provide dental protection

The treated water finally passes to the clear water tank. It is sent through the pumping station for storage in service reservoirs and then flows to the consumers via the distribution network.


Why does the tap water contain a smell of chlorine?

As the majority of Hong Kong people live in high‐rise buildings, it may take a long time for the final water from treatment works to go through the roof tanks before supplying to the consumers. A small amount of residual chlorine is maintained in the water to keep it free from bacterial infection during its journey in the distribution system. This minimal amount of chlorine will disappear if the water is boiled.

Preparing for Challenges Ahead

Challenges for Water Supply in Hong Kong

Inadequate yield collected from local catchment and Dongjiang water supply due to climate change

Increasing demand for freshwater due to rapid population and economic growth

Competition for water resources in the Pearl River Delta region


The Hong Kong Observatory has forecast that climate change will intensify, with more frequent occurrences of extreme weather and a higher chance of long‐lasting droughts or heavy rain. An increase in dry weather would inevitably affect our local yield and also the Dongjiang water resources. Extreme rainfall is not desirable either. High levels of rainfall in a short period of time resemble pouring a large amount of water into a cup in a short time and causing water to overflow. Coupled with our increasing demand for water, these factors pose a number of challenges for water resource management.

Total Water Management Strategy

The Total Water Management Strategy was promulgated by the WSD in 2008 putting an emphasis on containing the growth of water demand and exploiting new water resources so that Hong Kong can be better equipped to deal with future water challenges. On water demand management, we have been actively strengthening the public’s awareness of water conservation through promotion and public education, as well as promoting the use of water‐saving devices.

From 3 to 6 Taps

On the other hand, to better prepare for future uncertainties resulting from climate change, we are striving to exploit alternative water sources which are less susceptible to climate change. We aim to increase our water sources from 3 to 6 which will support Hong Kong’s enhanced water security, reliability and resilience.

Desalination

Reclaimed Water

Grey Water Recycling / Rainwater Harvesting

Desalination

Desalination removes dissolved salts and impurities from seawater and turns it into fresh, drinking quality water. Desalination is practised in 150 countries around the world. Two major types of technologies for desalination are membrane desalination and thermal desalination. With the advance in membrane technology such as development in high‐performance equipment and energy recovery devices, there has been breakthrough in solving the energy problem of desalination technology in the past two decades.

Desalination

To provide a water resource which is resilient to climate change

To safeguard Hong Kong’s freshwater supply against droughts and population growth

To ensure that the quality of treated water complies fully with the World Health Organization’s Guidelines for Drinking‐water Quality

Membrane Desalination ‐ Principle of Reverse Osmosis

Natural Osmosis: A natural phenomenon where freshwater migrates from higher water potential (the freshwater side) to lower water potential (the seawater side) through the semi permeable membrane.

Reverse Osmosis: A process of applying excessive pressure to force water from the seawater through a semi‐permeable membrane to the freshwater side (desalination).


We plan to construct a seawater desalination plant adopting reverse osmosis technology at Tseung Kwan O Area 137. Watch the video “The Amazing Journey of Water Desalination” to know more about seawater desalination:

https://youtu.be/xwZbMI1ecBg


Reclaimed Water

Most sewage is treated to a certain standard before discharging into receiving water body – usually a river or the sea. In contrast, reclaimed water goes through additional process and is more highly treated to make it clear in appearance, odourless and safe for reuse, and it forms part of the water supply for non‐potable uses.

Pilot schemes involving the use of reclaimed water began in Hong Kong in 2006. The

Government has commissioned the first pilot scheme at Ngong Ping to provide reclaimed water, by converting the treated effluent from sewage treatment works, for non‐potable uses. The use of reclaimed water for non‐potable purposes can save freshwater and reduce

the amount of treated effluent discharge. It can be regarded as a water‐saving and environmentally friendly water resource.

The Water Supplies Department continues to supply reclaimed water, converted from tertiary treated sewage effluent at the Shek Wu Hui Sewage Treatment Works, to the north‐eastern part of the New Territories for non‐potable uses starting with Sheung Shui and Fanling from 2022 onwards. The supply of reclaimed water is estimated to save Hong Kong about 21 million cubic metres of freshwater each year.

Grey Water Recycling / Rainwater Harvesting

Water collected from baths, showers, wash basins, kitchen sinks and laundry machines etc. is known as grey water. Along with harvested rainwater, the grey water can be treated and reused for non‐potable purposes such as toilet flushing.

We have formulated guidelines on the implementation of rainwater harvesting and grey water recycling systems so that new government buildings with the potential of reducing their freshwater demand for non‐potable applications through rainwater harvesting or grey water recycling system can install on‐site treatment and recycling facilities. The guidelines have been incorporated in the joint Development Bureau and Environment Bureau Technical Circular on Green Government Buildings issued in April 2015.

On the other hand, the WSD is planning to construct a centralized grey water recycling system treating grey water collected from inhabitants at the Anderson Road Quarry development site for flushing use. The system will comprise a grey water treatment plant with associated pumping system, a service reservoir, pipes for grey water collection and the distribution of the treated grey water to consumers.

Saving Every Drop

Water Conservation Initiatives by the WSD

Water Supplies Department has been promoting water conservation through collaboration with stakeholders, combination of promotional and education efforts, and adopting “a voluntary first, and then mandatory” approach to promote the use of water‐saving devices.

“Let’s Save 10L Water” Campaign

The Water Supplies Department (WSD) launched the “Let’s Save 10L Water” Campaign on the World Water Day on 22 March 2014 with the aim of encouraging the public to actively reduce their daily domestic water consumption by 10 litres or more and to establish good habits of conserving water.

“Cherish Water Campus” Integrated Education Programme

This programme was launched for primary schools in the 2015/16 school year with the aim of enhancing primary students’ knowledge of global water resources and raising their awareness of water conservation; encouraging them to put water conservation into practice in school and at home, as well as conveying the message to their peers, family members and further to the community. To facilitate an effective implementation of this programme, the WSD will provide schools with teacher training workshops and teaching kits to enhance teachers’ understanding towards the programme as well as knowledge of water resources.

Water Resources Education Centre

The Water Resources Education Centre was established to enhance the younger generation’s knowledge of water resources. It aims to introduce students to the importance of water conservation in detail via exhibits, live demonstrations and interactive games through their experiencing “The Hong Kong Water Resource Discovery Journey”.

The Water Resources Education Centre at Mongkok Office of the Water Supplies Department has stopped operation since June 2018. The new Water Resources Education Centre, located at Tin Shiu Wai, is expected to be opened in 2019. It will introduce new initiatives and in‐depth materials covering various aspects and information of water resources.

Facebook Fanpage of “Water Save Dave”, Water Supplies Department’s Mascot

The fanpage provides the latest news about WSD and tips about “Water Conservation” and “Cherishing of Water Resources”.

The Water Efficiency Labelling Scheme

The Voluntary Water Efficiency Labelling Scheme (WELS) was launched by the WSD in 2009

to promote water conservation. Products participating in WELS will incorporate a water efficiency label that will tell consumers the level of water consumption and water efficiency to help consumers choose water efficient products for water conservation.

To promote the use of water‐saving devices, the WSD has mandated the use of designated water‐efficient devices registered under WELS in the proposed plumbing works for kitchens of domestic premises as well as for bathrooms and toilets of all premises since 1 February 2018. We are exploring, through legislation, mandating water efficient labels for designated water using devices on sale in the retail market to facilitate consumers in choosing water‐efficient products to further achieve water conservation purposes.

Water‐Saving Tips

Kitchen

Do not thaw food under running water. Let it defrost overnight inside the refrigerator instead.

Do not wash dishes and vegetables under a running tap. Wash them in a sink or container filled with water.

Water plants with the same water used for washing vegetables and fruits.

Install flow controller on water tap.

Bathroom

Take shorter shower instead of bath.

Use water‐saving devices, e.g. water‐efficient showerhead, tap, washing machine and dual flush toilet cistern, and pay attention to water efficiency labels.

Turn off the tap while brushing teeth, soaping hands or shaving.

For dual flushing cistern, use reduced flush for liquid waste and avoid flushing

unnecessarily.

Install flow controller on water tap.

Laundry and other areas

Only run washing machines or dishwashers with a full load.

Wash cars with the water bucket and towel, instead of a running hose.

Teach children that water is not for games.

Check your water bill and monitor your family’s water consumption. If your consumption is more than average, review your family’s water usage habits.

Fix dripping taps and water mains promptly.
