Vaal River
Focus 10

11. Background
Rand supplies metropolitan municipalities, local municipalities, mines and industries
Rand Water’s distribution network includes over ,056 kilometres of large diameter pipeline, feeding 58 strategically located service reservoirs.
Rand Water abstracts water from the Integrated Vaal River
Its supplies, on average, 3,653 million litres of water to these customers daily.
EMM is the second largest RW customer abstracting 1,000 million litres daily (27.4% of RW supplies)

12. VAAL RIVER SYSTEM ALLOCATIONS

13. EKURHULENI WATER DEMAND
Average daily demand(ADD)(15/16) : 1,000Ml/day;
Dry Weather Flow(ERWAT) : Ml/day
Rand Water abstraction licence : 4,383Ml/day
Current Rand Water demand : 4,400 Ml/day

14. Water restrictions & Water by-laws

15. Water Restrictions Problem Statement
All combined Vaal River System customers annual water demand is capped at 3,000 million cubic metres per annum
Current annual demand is 3,200 million cubic metres per annum
Current combined VRS capacity is 55% (Aug 2016)
In terms of the VRS operating rules as agreed by all stakeholders at 1% risk or 99% assurance ( i.e in 100 years you allow for 1 year of “no water” situation) as soon as the system reaches 60% capacity as the case now , water restrictions have to be implemented
Except for EMM during 2015/16 all other customers recorded average 2% water demand growth
EMM recorded 0.5% deep in water demand growth
Therefore water restrictions have to be instituted
Situation can only be reviewed if the VRS has more than 60% capacity possibly during the rain season

16. Reconciliation Scenario
High with target WC/WDM
Desalination of Mine Water
Unlawful removed
Re-use 80% of surplus yield in the Crocodile West River System
High Water Requirement Scenario with
Water Conservation and Demand Management & Re-use
Polihali Dam Yield
AMD reuse
Yield increases due to
removal of dilution releases
System
Yield
A third reconciliation scenario was recently considered to indicate the water balance situation if excess return flows in the Crocodile West River system are re-used to offset abstractions from the Vaal River System (this is by reducing supply through the Rand Water bulk supply system).
This scenario was formulated in response to the results presented at the November 2013 Strategy Steering Committee of the Crocodile West River System where it was shown excess water will be available for re-use after all the water needs in the Crocodile West River System and the transfers to the Lephalale area has been satisfied. This will also then be able to assist the shortfalls resulting from the late implementation of LHWP II as well as the fact that the treatment of AMD will not be on time.
The implication of implementing re-use implies Phase 2 of the LHWP can be postponed until 2023 as reflected on the graph, but the risk of shortfalls before the AMD can be treated is also indicated in red.
Desalinate AMD
First transfer from LHWP Phase II 16

17. Vaal System Strategies
Eradicate large unlawful irrigation use by 2016
Implement WCWDM programme to save 15% by 2016
Treat and use mine effluent by 2015?
Prepare for implementation of LHWP 2 to deliver water by 2024
Investigate re-use of urban return flows
Implement WQ management measures

18. Is RSA sliding into a water crisis situation?
NO if :
Water Conservation/ Water Demand Management,
effluent reuse,
curbing of unlawful use
promotion of groundwater use
curbing of deteriorating water quality
timely decisions on appropriate investments

19. Water Restrictions Framework
DWA through RW have directed Level 1 , 15% reduction in water demand for domestic & 20% industrial use reduction for irrigation
This may be escalated to Level 2 constituting 50% of current demand should the situation deteriorate
The Minister of Water Affairs published the Government Gazette on the 12th of Aug 2016 in terms of Item 6 of schedule 3 of the NWA of 1998
Section 12 of the EMM Water By Law provides for water restrictions
Section 16 of the 2015/16 Water and Sanitation Tariff Schedule also provides for imposition of water restriction tariffs upon pronouncement of water restrictions.

20. Council Approved Water Restrictions
That restrictions and prohibitions on water use according to the water supply by-laws will be implemented and enforced.
That a 10% price increase be imposed on all water consumption above 25 kiloliters per month for all household/domestic users. 
3. That the applicable water restriction tariffs, according to the 2016/17 tariff policy, be imposed on all other user categories who fail to reduce their average daily consumption by 15%.  
4. That the situation be reviewed in May 2017 or earlier as the case maybe as directed by the Minister of Water and Sanitation and Rand Water.

34. Water Resources Options And Priority For EMM
Water loss Eradication
Rainwater and stormwater harvesting
Treated Effluent Reuse
Ground Water use
Acid Mine Drainage –use of neutralised water & acid mine drainage -potable use of desalinated water

35. Rainwater Harvesting

36. Legal Context
The National Water Act (NWA) (Act No. 36 of 1998) is the overarching legal instrument of water resources management in South Africa.
The Water Services Act (WSA) (Act No. 108 of 1997) provides a regulatory framework for the provision of water supply and sanitation services to which people are entitled.
Also subject to the specific requirements of the National Environmental Management Act (NEMA) (Act No. 107 of 1998)

37. Assuming 100,000 properties amenable to RWH in EMM
Technical Context
Assuming 100,000 properties amenable to RWH in EMM
Each with roof area of 100m2
Each receiving 700mm precipitation annually
The volume of water that could be potentially harvested is :
100,000 x 100m2 x 0.7m = 7,000 Ml (1 week supply to EMM)
That would translate to R35 million rands saving

38. Legal Context - NWA
Recognizes the right to use water for purposes such as reasonable domestic use, domestic gardening, and animal watering.
It excludes any commercial activity.
RWH can be categorized as land‐based activities which reduce stream flow, and therefore require regulation by the Minister of Water and Environmental Affairs under Chapter 4, Part 4, Section 36 (2).
Some RWH systems require works that bear semblance to water works and their use might be restricted under section 27 (1) (a) to (d) of the NWA.

39. Legal Context - WSA
Section 3 of Chapter 1 of the WSA states that rainwater can be harvested from a dwelling’s roof to provide water for basic needs
Section 6 (1) requires users of rooftop RWH systems to get the approval of their water services providers.

40. Legal Context - The National Environmental Management Act Dilemma
RWH does not fall under the list of activities listed in section 24(5) of the NEMA (published in Government Notice No. R. 385‐387 of 2006) that require an Environmental Impact Assessment.

Wash laundry & dishes with full loads
Always turn off running water
Take shorter showers
Eliminate any and all leaks
Reduce the flow of toilets & showerheads
Today we will talk about 5 easy ways you can reduce the amount of water you use in your home. By reducing your water consumption you also save money on your water bill.

45. Water Saving Tips
Install automatic low-flow faucets in all major buildings,
Install low-flow toilets, urinals, and faucets in restrooms ,
Used non-potable water to water flowers
Turn off any unnecessary flows and equipment when not in use.
Ensure water pressures and flows are set at minimum required settings.
Water used in general cleaning can be as much as 10% of all water used in some work places.
Devise measures to reduce the excessive use.

Water Saver or Water Waster?
Here is an example of one consumer’s water use over one day. This consumer took 1 shower, flushed the toilet four times, brushed his teeth twice, shaved once and did a load of laundry and one of dishes. To get a good estimate you need to know how much water your shower, faucets, toilet, washing machine and dishwasher use. Include all family members to get a household estimate then divide by the number of people in your house. For example, if two people lived in this house and used a total of their water use would be 64 gallons per person (for a total of 128 gallons).
In this example of a single consumer household, is he or she a water saver or water waster?
ANSWER: water waster

48. Wash a full load of laundry
Average water use
Older washing machine litres
New washing machine < 106 litres
For small loads of laundry, adjust the water setting to a lower level.
The first tip is to always Wash full loads of laundry and dishes.
A washing machine uses a lot of water, so if you are in the market to buy a new machine look for a model that uses less water. The newer horizontal axis, or front loading machines, use less than half the amount of water of the older top-loading machines. If you don’t want to buy a new machine, just make sure that you only do laundry when you have a full load. You can save 300 to 800 gallons of water a month by washing only full loads of laundry.

49. Wash a full load of dishes
Average water use:
Older machine to 57 litres
Newer machine to 27 litres
Don’t pre-rinse, just scrape the dishes
Just a few dishes?
Wash in the sink or a dish pan
Rinse with sprayer or in a pan
The same thing is true for washing full loads of dishes in the dishwasher and the newer machines use about half the amount of water as the older models.
One of the greatest water wasters with dishes is pre-rinsing or washing dishes prior to putting them in the dishwasher. A dishwasher is designed to clean dirty dishes. The appliance manufacturers recommend scraping dishes rather than pre-rinsing prior to putting them in the dishwasher. Most dishwashers will clean the dishes without pre-rinsing. The only time you may need to do that is when the dishes are washed only once a week or so. In this case, it may make sense to wash the dishes in a sink filled with water.

50. Always turn off running water
Average faucet water flow:
Older 7.2 to 11.4 litres per minute
New ≤ 4.5 litres per minute
Turn the water on and off when:
Brushing your teeth
Shaving
Keep drinking water in refrigerator
The second tip is to ALWAYS turn off running water. A major water waster in many homes is a running faucet. People brush their teeth and shave while letting the water run down the drain. You can save several gallons every day just by turning the water on and off while brushing your teeth and shaving. You could also try shaving or brushing your teeth in the shower.
Other ways to save water are to keep chilled water in the refrigerator for drinking. This can reduce running water and you can reduce or eliminate the use of ice to cool the water. It is also better to defrost food in the refrigerator instead of under running water. If you can compost that is much better than using a garbage disposal.

51. Always save clean running water
Collect water in buckets while waiting for shower water to warm
Use it for:
Watering indoor plants
Mopping the floor
Household chores
As you are warming the shower water, put a bucket in to collect the clean water. This water can be used for several things in your home, such as watering plants, mopping the floor and a variety of household chores.

52. Take shorter showers Reduce your 10 minute shower to 5 minutes
Save up to 304 litres of water
Take a “navy shower”
Turn the water off while you lather up and shampoo
Install a toggle switch to maintain a consistent temperature
Lower your bath water
The third tip is to Take shorter showers. Many people spend 10 minutes in the shower at least once if not twice a day. A good way to save water is to cut your shower time in half or take what is often called a “navy shower.” A navy shower is when you wet down, turn the water off, lather up and then turn the water back on to rinse off. To control the temperature you can install a toggle switch that cuts the flow of water at the nozzle. Depending on the flow rate of your showerhead, you can save up to 80 gallons. Most showerheads use 2.5 gallons of water per minute.
If you like to take a bath, you should fill the tub about 1/3 full or with 5 inches of water.

53. Eliminate any and all leaks
LEAKY FAUCET
One drop per second = 36.1 litres a day
LEAKY TOILET
57 litres of water a day lost
FINDING TOILET LEAKS
Remove the toilet tank cover and put in 5 to 10 drops of food coloring.
Wait 30 minutes.
If any color leaks into toilet bowl then you have a leak and you should fix it immediately.
The fourth tip is Eliminate the leaks in your house. The average consumer loses 9.5 gallons a day through leaking faucets and toilets. Just one dripping faucet wastes 9.5 gallons in a day. If you also have toilet leak, you are wasting even more water.
Be sure to turn faucets off to reduce leak problems, but don’t turn the handles too tight because you can damage the hardware. It is easy to see if your toilet is leaking. Put a few drops of food coloring or instant coffee in the toilet tank. Leave it for 30 minutes. If you see any color in the toilet bowl then there is a leak. You may just need to replace the flushing mechanism. This is a quick low cost fix to what can be a very costly problem.

54. Reduce the flow of toilets
Almost half of the water used in a home is for toilets & showers.
Replace old toilets with new models using 6 litres per flush or less
Reduce the water used per flush
Place a 2 liter bottle filled with pebbles or sand in the toilet tank. Saves about 2 litres per flush
The fifth and final tip is to Reduce the flow of water from your toilets and showers. Toilets and showers account for close to half of the water used in your home, so these are great places to start when trying to reduce your water use.
The best option with toilets is to replace old high water use models with low-flow models. A low-flow can reduce the water used per flush down to 1.3 or 1.5 gallons per flush. A quick fix that will reduce your water use by ½ gallon, is to place a 2 liter bottle filled with pebbles or sand in the back of the toilet tank. Be careful that you don’t interfere with the flushing mechanism.
NOTE: It isn’t a good idea to put bricks in the toilet tank. Over time a brick will disintegrate and could damage your toilet or plumbing.

55. Reduce the flow of showerheads
Measure water flow
Hold a bucket under the showerhead.
Turn the water on full blast for thirty seconds.
Measure the number of 5 litres containers to get number of litres per minute.
Replace showerhead if over 10 litres per minute
Older showerheads use 8 to 38 litres per minute
You should also reduce the flow of water from your showerhead. The average showerhead uses 2.5 gallons of water a minute. A low-flow showerhead can easily reduce the flow to 1.5 gallons per minute.
If you don’t know how much water your shower uses, you can measure the flow rate per minute with a bucket. You could hold the bucket under the showerhead for one minute, but it is easier to check the flow for 30 seconds and multiply by two to get the per minute flow.

56. Low-Cost Ways to Save Water
Toilet
Flush less often
Don’t use it for a trash can
Shower
Cut your shower time in half
Bathing (tub)
Reduce water level to 1/3 full
Keeping the 5 easy water saving tips in mind, here are some easy low-cost and no-cost ways you can start saving water today.
1. Stop using the toilet as a trash can. Remember that every time you flush you use from 2 to 8 gallons of water. Just toss it in the trash can.
2. Cut your shower time in half.
3. If you like to take a bath, consider a 5 minute shower instead or reduce the water level in the tub.

57. Low-Cost Ways to Save Water
Install aerators on faucets
Reduce the flow from 7.6 to 11.4 litres per minute to 5.7 litres per minute
Wash full loads of laundry & dishes
Stop washing one dish at a time
Save up to 57 litres by washing & rinsing in the sink or a dish pan
Go through your house and install low-flow faucet aerators on your bathroom and kitchen faucets. Aerators work by reducing the water flow and increasing pressure, then mixing air with the water as it comes from the tap. Even though you're using less water, it will seem like the flow is stronger. Aerators are fairly inexpensive.
Never wash a partial load of laundry without at least adjusting the water level. Don’t run your dishwasher unless you have a full load and don’t pre-rinse your dishes. If you prefer to wash dishes by hand, always fill the sink or a basin with water. Never wash dishes one at a time under a stream of running water! Use a sprayer or pan of water to rinse the dishes.

58. Long-Term Water Conservation
Hot Water
Insulate water pipes to get hot water faster and avoid wasting water while it reaches the correct temperature
Install an on-demand or tankless hot water heater
You can reduce your hot water use by investing in an on-demand or tank less hot water heater. This type of hot water heater heats the water as you need it rather than storing water in a tank.
