Water Use

1. How can we Encourage People to use Water Wisely and Reduce Wastage?

Education is the most important way to encourage people to be Water Wise. If people are informed and aware of a situation, they have the power to make the correct choice. Rand Water’s six meanings of being water wise are very important in outlining why and how people need to save water and look after it.

The 3Rs.

  • Reduce your daily water use. It is easy to do;
  • Reuse water where possible. Most tap water can be used at least twice;
  • Repair leaking pipes, toilet cisterns and taps. Inspect your water metre and carry out a water audit to identify water that may be leaking without you knowing it.

As individuals there are many simple measures to use water wisely on a daily basis and not just in times of drought. These include reducing water wastage; reusing water where possible; identifying and repairing leaks; avoiding water pollution; protecting our wetlands; planting indigenous plants in our gardens and reducing our carbon footprint. Although each individuals water saving is small, when added together the amount of water we can save is significant.

The following are some tips on how to be water wise:


  • Monitor your water bill for unusually high use. Your bill and water meter are tools that can help you discover leaks.
  • We're more likely to notice leaks indoors, but don't forget to check outdoor faucets, sprinklers and hoses for leaks.
  • If you have an automatic refilling device, check your pool periodically for leaks.
  • When buying new appliances, consider those that offer cycle and load size adjustments. They're more water and energy efficient.
  • When you save water, you save money on your utility bills too. Saving water is easy for everyone to do.
  • Insulate hot water pipes for more immediate hot water at the faucet and for energy savings.
  • Make suggestions to your employer about ways to save water and money at work
  • Support projects that use reclaimed wastewater for irrigation and industrial uses.
  • Washing dark clothes in cold water saves both on water and energy while it helps your clothes to keep their colours.
  • Report broken pipes, open hydrants and errant sprinklers to the property owner or your water provider.
  • Share water conservation tips with friends and neighbours.
  • Setting cooling systems and water softeners for a minimum number of refills saves both water and chemicals, plus more on utility bills.
  • While staying in a hotel or even at home, consider reusing your towels.
  • Have your plumber re-route your grey water to trees and gardens rather than letting it run into the sewer line.
  • When you have ice left in your cup from a take-out restaurant, don't throw it in the trash, dump it on a plant.

Garden and outdoors:

  • Adjust sprinklers so only your lawn is watered and not the house, sidewalk, or street.
  • Choose shrubs and groundcovers instead of turf for hard-to-water areas such as steep slopes and isolated strips.
  • Plant in the fall when conditions are cooler and rainfall is more plentiful.
  • Water your lawn and garden in the morning or evening when temperatures are cooler to minimise evaporation.
  • Spreading a layer of organic mulch around plants retains moisture and saves water, time and money.
  • Use a broom instead of a hose to clean your driveway and sidewalk and save water every time.
  • If water runs off your lawn easily, split your watering time into shorter periods to allow for better absorption.
  • Check the root zone of your lawn or garden for moisture before watering using a spade or trowel. If it's still moist two inches under the soil surface, you still have enough water.
  • Adjust your lawn mower to a higher setting. A taller lawn shades roots and holds soil moisture better than if it is closely clipped.
  • When cleaning out fish tanks, give the nutrient-rich water to your plants.
  • Use sprinklers for large areas of grass. Water small patches by hand to avoid waste.
  • Walkways and patios provide space that doesn't ever need to be watered. These useful "rooms" can also add value to your property.
  • Collect water from your roof to water your garden.
  • Rather than following a set watering schedule, check for soil moisture two to three inches below the surface before watering.
  • Install a rain sensor on your irrigation controller so your system won't run when it's raining.
  • Don't use running water to thaw food. Defrost food in the refrigerator for water efficiency and food safety.
  • Use drip irrigation for shrubs and trees to apply water directly to the roots where it's needed.
  • Grab a wrench and fix that leaky faucet. It's simple, inexpensive, and you can save 550 litres a week.
  • Reduce the amount of lawn in your yard by planting shrubs and ground covers appropriate to your site and region.
  • Remember to check your sprinkler system valves periodically for leaks and keep the sprinkler heads in good shape.
  • Don't water your lawn on windy days when most of the water blows away or evaporates.
  • Water your plants deeply but less frequently to encourage deep root growth and drought tolerance.
  • Know where your master water shut-off valve is located. This could save water and prevent damage to your home.
  • To decrease water from being wasted on sloping lawns, apply water for five minutes and then repeat two to three times.
  • Group plants with the same watering needs together to avoid over watering some while under watering others.
  • Use a layer of organic material on the surface of your planting beds to minimise weed growth that competes for water.
  • Use a minimum amount of organic or slow release fertiliser to promote a healthy and drought tolerant landscape.
  • Trickling or cascading fountains lose less water to evaporation than those spraying water into the air.
  • Use a commercial car wash that recycles water.
  • Avoid recreational water toys that require a constant flow of water.
  • Use a rain gauge, to track rainfall on your lawn. Then reduce your watering accordingly.
  • Encourage your school system and local government to develop and promote water conservation among children and adults.
  • Learn how to shut off your automatic watering system in case it malfunctions or you get an unexpected rain.
  • Next time you add or replace a flower or shrub, choose a low water use plant for year-round landscape color and save up to 2000 litres each year.
  • Use a grease pencil to mark the water level of your pool at the skimmer. Check the mark 24 hours later to see if you have a leak.
  • If your dishwasher is new, cut back on rinsing. Newer models clean more thoroughly than older ones.
  • Use a trowel, shovel, or soil probe to examine soil moisture depth. If the top two to three inches of soil are dry it's time to water.
  • If installing a lawn, select a turf mix or blend that matches your climate and site conditions.
  • When the kids want to cool off, use the sprinkler in an area where your lawn needs it the most.
  • Make sure your swimming pools, fountains, and ponds are equipped with re-circulating pumps.
  • Consult with your local nursery for information on plant selection and placement for optimum outdoor water savings.
  • Wash your car on the lawn, and you'll water your lawn at the same time.
  • Leave lower branches on trees and shrubs and allow leaf litter to accumulate on the soil. This keeps the soil cooler and reduces evaporation.
  • Use a hose nozzle or turn off the water while you wash your car. You'll save up to 4000 litres every time.
  • Let your lawn go dormant during the summer. Dormant grass only needs to be watered every three weeks or less if it rains.
  • Plant with finished compost to add water-holding and nutrient-rich organic matter to the soil.
  • Use sprinklers that deliver big drops of water close to the ground. Smaller water drops and mist often evaporate before they hit the ground.
  • Water only when necessary. More plants die from over-watering than from under-watering.
  • Adjust your watering schedule each month to match seasonal weather conditions and landscape requirements.
  • Apply water only as fast as the soil can absorb it.
  • Aerate your lawn at least once a year so water can reach the roots rather than run off the surface.
  • When backwashing your pool, consider using the water on your landscaping.
  • For hanging baskets, planters and pots, place ice cubes under the moss or dirt to give your plants a cool drink of water and help eliminate water overflow.
  • Throw trimmings and peelings from fruits and vegetables into your compost.
  • Wash your pets outdoors in an area of your lawn that needs water.
  • When washing dishes by hand, fill the sink basin or a large container and rinse when all of the dishes have been soaped and scrubbed.
  • When you give your pet fresh water, don't throw the old water down the drain. Use it to water your trees or shrubs.
  • If you accidentally drop ice cubes when filling your glass from the freezer, don't throw them in the sink. Drop them in a house plant instead.


  • If your shower fills a 5 litre bucket in less than 20 seconds, replace the showerhead with a water-efficient model.
  • Shorten your shower by a minute or two and you'll save up to 600 litres per month.
  • Upgrade older toilets with water efficient models.
  • Put food colouring in your toilet tank. If it seeps into the toilet bowl without flushing, you have a leak. Fixing it can save up to 4000 litres a month.
  • When running a bath, plug the tub before turning the water on, then adjust the temperature as the tub fills up.
  • When doing laundry, match the water level to the size of the load.
  • Teach your children to turn off faucets tightly after each use.
  • Use a water-efficient showerhead. They're inexpensive, easy to install, and can save you up to 3000 litres a month.
  • Before you lather up, trade up your current shower head to a water-efficient shower head which helps reduce water consumption by up to 40%. Water-conserving shower heads are inexpensive, easy to install, and can save a family of four up to 66000 litres of water a year.
  • Turn off the water while brushing your teeth and save 1000 litres a month.
  • Bathe your young children together.
  • Drop your tissue in the trash instead of flushing it and save water every time.
  • If your toilet was installed before 1992, reduce the amount of water used for each flush by inserting a displacement device in the tank.
  • Listen for dripping faucets and running toilets. Fixing a leak can save 1200 litres a month or more.
  • Turn off the water while you wash your hair to save up to 600 litres a month.
  • Turn off the water while you shave and save up to 1200 litres a month.
  • To save water and time, consider washing your face or brushing your teeth while in the shower
  • Keep a bucket in the shower to catch water as it warms up or runs. Use this water to flush toilets or water plants.
  • When you are washing your hands, don't let the water run while you lather.


  • When washing dishes by hand, don't let the water run while rinsing. Fill one sink with wash water and the other with rinse water.
  • Some refrigerators, air conditioners and ice-makers are cooled with wasted flows of water. Consider upgrading with air-cooled appliances for significant water savings.
  • Run your clothes washer and dishwasher only when they are full. You can save up to 3900 litres a month.
  • Install covers on pools and spas and check for leaks around your pumps.
  • Use the garbage disposal sparingly. Compost vegetable food waste instead and save litres every time.
  • For cold drinks keep a jug of water in the refrigerator instead of running the tap. This way, every drop goes down you and not the drain.
  • Wash your fruits and vegetables in a pan of water instead of running water from the tap.
  • Collect the water you use for rinsing fruits and vegetables, then reuse it to water houseplants.
  • Designate one glass for your drinking water each day or refill a water bottle. This will cut down on the number of glasses to wash
  • Soak pots and pans instead of letting the water run while you scrape them clean.
  • Set a kitchen timer when watering your lawn or garden to remind you when to stop. A running hose can discharge up to 40 litres a minute.
  • Make sure there are water-saving aerators on all of your faucets.
  • Install an instant water heater near your kitchen sink so you don't have to run the water while it heats up. This also reduces energy costs.
  • Insulate hot water pipes for more immediate hot water at the faucet and for energy savings.
  • One more way to get eight glasses of water a day is to re-use the water left over from cooked or steamed foods to start a scrumptious and nutritious soup.

5. How can the problem of leaking taps be combated?

Leaks can account for, on average, 41639.53 litres of water wasted in the home every year, which is enough to fill a backyard swimming pool. 

Ten percent of homes have leaks that waste 340.69 litres or more per day.
Common types of leaks found in the home include leaking toilet flappers, dripping faucets, and other leaking valves. All are easily correctable. Fixing easily corrected household water leaks can save homeowners more than 10 percent on their water bills.

Keep your home leak-free by repairing dripping faucets, toilet valves, and showerheads. In most cases, fixture replacement parts don't require a major investment and can be installed by do-it-yourselfers.

The vast majority of leaks can be eliminated after retrofitting a household with new WaterSense labeled fixtures and other high-efficiency appliances.

Leak Detection:

A good method to check for leaks is to examine your winter water usage. It’s likely that a family of four has a serious leak problem if its winter water use exceeds 45424.94 litres per month.

Check your water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, you probably have a leak. One way to find out if you have a toilet leak is to place a drop of food coloring in the toilet tank. If the color shows up in the bowl without flushing, you have a leak. Make sure to flush immediately after this experiment to avoid staining the tank.

Faucets and Showerheads:

A leaky faucet that drips at the rate of one drip per second can waste more than 11356.24 litres per year. Leaky faucets can be reduced by checking faucet washers and gaskets for wear and replacing them if necessary.

A showerhead leaking at 10 drips per minute wastes more than 18792.71 litres per year. That's enough water to wash 60 loads of dishes in your dishwasher.

Most leaky showerheads can be fixed by ensuring a tight connection using pipe tape and a wrench.


If your toilet is running constantly, you could be wasting 757.08 litres of water or more every day.
If your toilet is leaking, the cause is most often an old, faulty toilet flapper. Over time, this inexpensive rubber part decays, or minerals build up on it. It's usually best to replace the whole rubber flapper—a relatively easy, inexpensive do-it-yourself project that pays for itself in no time.


An irrigation system should be checked each spring before use to make sure it was not damaged by frost or freezing. Check your garden hose for leaks at its connection to the spigot. If it leaks while you run your hose, replace the nylon or rubber hose washer and ensure a tight connection to the tap using pipe tape and a wrench.


6. How do you change a washer in a tap?

In most cases a dripping/leaking tap is caused by the failure of its washer. All it takes to stop a leaking tap is about R1 for a new washer and a little bit of D-I-Y plumbing. 

1. Switch off you main water supply. Open the tap fully and allow water to run out completely. Plug the basin to prevent loose screws from falling down the drain. Unscrew the tap handle. 

2. Unscrew the bell-shaped cover and remove. Lay the parts down in the same order you remove them to simplify reassembly. 

3. Unscrew the head part with a water pump plier, or similar tool, and remove. 

4. Unscrew the washer retaining nut and remove the faulty tap washer. 

5. Replace with a new washer of the same size and type. 

6. Replace the nut. 

7. Re-install the spindle and screw down the cover. 

8. Close the tap. 

9. Restore the water supply and check for leaks. 

7. When is the Best time to Water the Garden?

In the early morning before 9am, or in the evening after 4pm. It is not good to water after 4pm in winter as the water that stays on the plants could freeze overnight and damage the plants. In winter the best time to water is mid-morning.


8. How can I use Water Wisely in the Garden?

  • Don’t over water your garden:
    • Summer = 25 mm per week.
    • Spring/Autumn = 15 mm per week.
    • Winter = 8 mm per week.
  • Attach a water tank to your drainpipe to collect rainwater.
  • Apply water directly to the root zone, using micro-irrigation. Drip irrigation is the most water efficient irrigation system.
  • Use a low pressure, water efficient dripper system that keeps the soil loose and friable, and retains its essential elements.
  • Avoid high pressure watering systems as they waste water, compact the soil and wash away both soil and the essential elements.
  • Use a sprinkler system with a large droplet size and low spray angle.
  • Switch off all automatic irrigation during rainy weather, or install a rain sensor.
  • Select sprinklers that match the water pressure.
  • Water your plants at the roots and water as deep as possible.
  • Make sure that the irrigation sprays target the plants and not your patio, driveway or the road.
  • Check for leaks in the irrigation system.
  • Use mulch (i.e. grass, leaves, bark, wood chips, pebbles, etc.) to keep the ground moist around the plants. Mulch reduces evaporation, run-off and weeds.
  • Group the plants into high, medium and low water use zones, so that they can be watered separately.
  • Grow plants that need less water. Exotic plants often require more water than indigenous ones.
  • Keep your lawn a minimum of 2cm long. This encourages healthier roots and protects the soil better from the hot sun. Less water is needed to keep the lawn growing.
  • Create water basins around trees & shrubs.
  • Make large square or rectangular beds so that most of the water goes to the plants, and not to the paths in between.
  • Avoid walking in the beds as this compacts the soil – rather use pathways.
  • Add water-retaining granules into the soil.
  • Aerate your lawn and around tress at least once a year to ensure good water penetration. Earthworms help aerate and fertilise the soil.
  • Turn soil and add compost when planting. This helps the soil hold moisture and produces healthier plants that require less water.
  • Herbs need less water than vegetables, so plant them in their own bed and water them less frequently.
  • In hot climates, put up shade cloth made from orange or green net vegetable bags.
  • Use berms, swales and channels to direct stormwater and runoff onto lawns or beds.
  • Maintain your garden by mowing, weeding, pruning and irrigating as needed. A well-maintained yard requires less water.

Outdoor Washing:

  • Sweep the paving with a broom instead of washing it with water.
  • Clean your car by filling a bucket with water rather than using a running hose.
  • Wash your car at home.
  • If you use a car wash make sure that the water is recycled in their system.

9. How can I use Water Wisely when Using the Toilet?

  • You can take a 1 litre plastic bottle and fill it up with water. When you flush the toilet, it will use 1 litre less. Be careful not to put a bottle in that is too big because the toilet needs a certain amount of water to flush down solid waste.
  • Remember only to flush when necessary, for example, if you blow your nose on a tissue and put it in the toilet, it is a waste to flush it down, rather throw it in the bin.

10. How can I use Water Wisely in the Kitchen?

  • Repair dripping taps.
  • Install water aerators or low flow restrictors in the taps.
  • Soak and scrape dishes and pots into the dustbin before washing them.
  • Don’t rinse glasses, fruit and vegetables under running water. Plug the sink and reuse the water in the garden.
  • Thaw frozen food in a refrigerator or a bowl of water, instead of under running water.
  • Reuse ice for watering plants and for drinking or cooking.
  • Don’t wait for a tap to run cold. Keep a bottle of water in the fridge.
  • When waiting for water out of the tap, place a bucket under the tap so that the cold water can be used later.
  • Only put as much water into your kettle as you need.
  • When boiling water on the stove cover the pot with a lid.
  • Buy a water (and energy) efficient dishwasher.
  • Fully load the dishwasher before use. Use an economy cycle.
  • When rinsing dishes before loading the machine place a small amount of water in the sink and rinse the dishes in that water instead of under running water.
  • If you have pre-rinsed your dishes then run the load on a shorter cycle. 

11. How can I use Water Wisely in the Bathroom?


  • Flush only when necessary.
  • Place a closed, flat-based 0.5 litre bottle filled with water in your toilet cistern, away from any moving parts, to reduce the amount of water used per flush.
  • Fit a dual-flush toilet cistern, i.e. a button for liquid waste (4 litres) and a button for solid waste (9 litres).
  • Don’t use the toilet as a rubbish bin.
  • Install a low-volume toilet, i.e. 9 litres.
  • Check if your toilet has a silent leak by putting a little food colouring in your cistern. If the colouring begins to appear in the bowl without flushing, there may be a leak.
  • If you have a flush handle toilet, pick up the handle once it's flushed, or bend the float arm downwards, so less water is allowed to refill the cistern.
  • Ensure that the washer in the cistern is fitted correctly to stop leaks.
  • Replace a tray urinal with a demand urinal valve, i.e. the valve needs to be pushed when water is needed to wash away the waste.


  • Turn off the tap while brushing your teeth.
  • Fix dripping taps.
  • Don’t turn the tap on full. Turn it off after use.
  • Don’t leave then tap running while rinsing hair or shaving.
  • Wash your hands with the plug in place.
  • Install aerators or low flow restrictors in your taps.
  • Use cold water to wash your hands instead of hot water.


  • Avoid filling the bath to a depth greater than 20 cm.
  • Keep the water pressure as low as possible.
  • Fix dripping taps.
  • Install aerators or low flow restrictors in your taps.
  • Reuse bath water for heavy cleaning jobs like floors and carpets.


  • Take 5 minute showers.
  • Install a water efficient showerhead (6-10 litres a minute).
  • Switch off the water between soaping and rinsing your body and your hair.
  • Place a bucket in your shower to collect the used water which you can reuse on lawns, shrubs and trees.

12. How can I use Water Wisely in the Laundry?

  • Wash your clothes in cold or warm water.
  • Ensure that you have a full load of washing when using the washing machine this saves water and electricity.
  • If your washing isn't very dirty then you don't use the pre-rinse cycle.
  • Buy a washing machine that is water (and energy) efficient.
  • Buy a washing machine that has different cycle options. This lets you choose a cycle that is more water (and energy) efficient when heavy duty cleaning is not needed.
  • Front loaders are more water (and energy) efficient than top loaders or twin tubs.
  • Select a machine that offers load detection. If there isn't enough washing to do a full load, the machine will only use the amount of water needed.

13. What can I do to my Geyser to Help Save Water and Electricity

  • Insulate water pipes and geyser.
  • Install geysers close to the draw-off points to avoid heat loss from piping water over long distances and this will also prevent large volumes of water being lost while the cold water is flushed out when the tap is opened
  • Install a solar panel for your energy needs in the house.

14. If I Waste Water, am I also Wasting Electricity? Why?

Purified water is a very special and expensive commodity. We are paying a very reasonable price for water in Gauteng if one considers the costs involved in getting purified water to our homes. One of the biggest costs is that of electricity, as every step of Rand Water’s purification, from the pumping of water to the maintenance of equipment requires large amounts of energy.

The less water we waste, the less electricity will be wasted in order to get more water to your home.

In addition, it is estimated that around three quarters of a household’s energy use relates to heating and hot water use, for example, in baths or showers or for washing clothes or dishes. By taking simple steps to avoid wasting water, (especially hot water) families should see a reduction in their energy bill, and those who are charged for their water by meter should see a reduction in their water bill as well.

The following are a few tips on how to save water and energy at the same time:

  • Replace worn washers on leaky taps. A dripping hot water tap wastes energy and over a year could unnecessarily add over R200 to your annual water bill.
  • Shorten your shower. For every minute you cut off your daily shower you could save between R70 and R100 off your energy bills over the year, or go one step further and install a water saving shower head, which can cut the amount of water used by about 30 per cent.
  • When putting the kettle on to boil, only fill it with as much water as necessary. Two-thirds of us waste energy by boiling more water than we need.
  • Make sure that the dishwasher or washing machine is completely full before turning it on, and avoid using the half load setting. Half-load cycles use much more than half the energy and water of a full load.
  • Washing machines use huge amounts of energy, 90 per cent of which is through heating water. By reducing the temperature from 40 to 30 degrees, energy consumption will be reduced by 40 per cent.
  • The hot water cylinder thermostat should be set at 60°C or 140°F. Any higher is a waste of energy and could lead to scalding.
  • Insulate the hot water cistern to avoid wasting energy to keep it hot. Fitting a jacket that is at least 75mm thick could save around R500 each year.

15. What can Consumers do to Reduce Demand for Water?

Fast fixes for households on water saving:

  • Fix any leaks: A dripping tap losing one drop a second will waste 15 litres of water a day.
  • Save water when washing: take a shower rather than a bath, don't leave the tap on when brushing your teeth and use the plug in the washbasin when shaving.
  • Save water in the kitchen: Use a bowl instead of leaving the tap on when washing up, boil only the amount of water you need in the kettle, and keep cool water in the fridge rather than running the tap to get a cold drink. And don't use dishwashers or washing machines half full.
  • Save water in the garden: Collect rainwater from the roof in a water butt, and give your plants a soaking once a week rather than watering daily. Water your plants in the early mornings or evenings, reducing the amount lost through evaporation.

Fast fixes for businesses:

  • Take regular metre readings: The majority of businesses are metered. By taking regular meter readings, you can monitor your water consumption. Meter readings can reveal if the amount of water used is too high.
  • Trace and repair leaks: Any leaks occurring in the pipes on a property will waste water and money. Leaks may be difficult to trace, but you can check if there is a leak on your premises by taking meter readings at night or at weekends when water is not normally used. Some water companies will also help business customers to check for leaks.
  • Water efficient taps: Dripping taps can waste a large amount of water over time. You could consider installing self-closing press taps that cut off the  supply after a short period.
  • Water efficient toilets: Some workplace toilets are programmed to flush allthe time, even when there is no-one in the building. Reduce waste by changing the settings, or by installing a sensor-controlled flushing system.
  • Appoint a water monitor: Assign a member of staff to walk regularly around the site, checking for any obvious waste or excessive water use.

16. Why must we use Water Wisely if water cannot be made or destroyed and it moves around the planet in the Water Cycle?

It is correct that water cannot be made or destroyed and the amount of water on this planet remains constant. Many people then ask why we should save water, as it will never run out and will return to us eventually in the water cycle. There are a number of reasons why it is very important that we as human beings look after our water resources and do not waste water or abuse it.

One reason is that it is expensive and time consuming to purify water and deliver it to homes. If water is wasted in a particular household, then it means more money must be spent to get more water to that household. We must also remember that it does not only cost money and time, but also many other of the earth’s precious resources. It takes a large amount of electricity to purify and pump water to our homes, and this has many impacts including coal mining and the water pollution associated with that industry; loss of bio-diversity and useful land where the coal is mined; air pollution and associated greenhouse gases and poverty associated with poorly paid mine workers. So if you waste water, you are not only having an impact on the economy of the country, but all of these aspects, social, economic and ecological, are negatively affected.

Another reason is that the very problem of global warming that we are causing through our increasing and unending energy requirements, is leading to climate change all over the planet. Melting ice caps caused by global warming can cause ocean currents to change, and therefore can affect climate on adjacent continents. We may be facing a much drier future in many parts of our country with changing rainfall patterns. This will affect our rivers and dams and put severe stress on our cities and overall economy. The price of water may increase drastically and it may not be possible to supply water to many people. There also may be many people that will not have access to water of any kind, let alone clean, purified water. This situation can lead to severe conflict situations not only between countries, but also within countries.
