7 INVEST CAPE TOWN WATER CRISIS DEBRIEF Presented by Lance Greyling Director: Enterprise & Investment

8 NEAR CAPACITY IN 2014

9 HOW DID WE GET HERE?

10 ANNUAL MAJOR DAM LEVELS All figures are for 25 September for each year

11 BETWEEN 2010 AND 2015, 130 MEGACITIES WERE HIT BY DROUGHT DISASTERS

12 Getting through it in 2018 requires that water use be greatly reduced by households, agriculture, commerce and industry alike.

13 THIS IS WHAT WE WANT TO AVOID

14 PHASES OF THE DISASTER PLAN We are currently in Phase 1 with Level 6b in effect from 1 February Day Zero is set for 12 April 2018, unless water use drastically reduces across the City PHASE 1 Preservation Restrictions (rationing) PHASE 2 Disaster Restrictions Day Zero PHASE 3 Full-scale disaster implementation We are currently in Phase 1 with Level 6b in effect from 1 February Day Zero is set for 16 April 2018, unless water use drastically reduces across the City.

15 DAY ZERO WHAT WILL HAPPEN ON DAY ZERO? From this point onwards most taps will be shut off so that the last available water in our dams can be preserved for basic use 200 sites have been confirmed and we will be erecting signage at these points within the coming weeks so that persons in these communities are aware of where their collection point will be situated. Water tankers will be used to deliver water to vulnerable groups such as old age homes and care facilities. We are also engaging retailers and the bottled water association to ramp up their distribution networks to increase bottled water supply, so that those who do not want to use the water collection points can purchase water. We will use the reticulation network to supply approximately 200 water collection sites with water. We are committed to working with industry to avoid day zero and to keep our economy functioning The water at the collection points will be fed through a core reticulation system that has been isolated from the rest of the network to supply critical infrastructure and the water collection points. Residents should be aware that the Day Zero phase is an extreme disaster scenario, and significant disruption of daily life is to be expected.

16 WATER DASHBOARD

17 WHAT ARE WE DOING TO ADDRESS IT?

18 PRESSURE MANAGEMENT More than 116 pressure management zones have been created Design underway for further 29 pressures management zones Throttling of bulk water valves is being done where benefits are identified These zones are being optimised during this current drought They are spread throughout the City and no specific areas are targeted High lying areas likely to experience most reduced pressure This will lead to outages in certain areas for approximately 10 hours a day

19 ONE OF THE LOWEST WATER LEAKAGE RATES IN THE WORLD Cape Town Municipality 16% National Average 36% DWS Strategic Overview of the Water Sector in South Africa 2017

20 ACTIVE DETECTION & REPAIRS Dedicated leak detection team (Includes EPWP and Rand Water graduates) Creation of 75 new positions to reduce response times to burst pipes and meter faults / leaks. Injection of R22m into this programme this year to improve response time Leak Detection in progress Vandalized hydrants and dumping in chambers

21 WATER MANAGEMENT DEVICES Up until end of 2016/ WMDs had been installed Approximately WMDs installed since mid-september 2017 focused on high water users Now being installed at rate of more than 2000 per week As of January all domestic properties using more than 10500kl/m to be fitted

22 TREATED EFFLUENT RE-USE FOR INDUSTRY More than 200 users have permanent connections More than 70 Industries are collecting treated effluent at WWTW and standpipe points Mostly used for irrigation and industrial purposes: - Golf courses - City Parks - Schools - Farmers - City Departments - Industries etc.

23 AUGMENTATION The City of Cape Town has been working towards a diversified supply for some time, but due to the expense of options other than surface water, the projects have progressed to pilot stage, rather than production. The full augmentation plan runs until June Short-term, temporary desalination (16 MLD) Groundwater abstraction (peak at 150 MLD) Springs Water re-use Water transfers Permanent desalination

29 WORLD BANK COMMENDATION The project management of Cape Town s new water supply is impressive. This was confirmed in November by World Bank consultants who spent time with the City to look at their plan. They agreed that the plan was excellent and one of the most detailed they had ever seen. The project management team has put in place a range of measures to speed up procurement time lines that are in line with private sector procurement, seldom seen within government. Gina Ziervogel, associate professor in the Department of Environmental and Geographical Science and Research Chair at the African Climate and Development Initiative, University of Cape Town.

30 LEVEL 6B WATER RESTRICTIONS: WHAT DOES IT MEAN FOR BUSINESS?

31 50 FOR 150 If we all use 50 litres for 150 days, we have a chance of making it to the next rainy season, without having to turn off the taps. Don t wait for Level 6b water restrictions, to reduce your use.

32 CITY WATER MAP The water map indicates water use for freestanding households only (no complexes, flats etc. are indicated) The data is for the previous month and might not correspond to your billing period. If there is no dot for your free-standing household, it means that your water use is more than litres per month. This could be due to: Undetected leaks High number of occupants Business run from the home Recently completed building work Etc. Full FAQs available online

33 RESTRICTIONS APPLICABLE TO NON-RESIDENTIAL CUSTOMERS All non-residential properties (e.g. commercial and industrial properties, schools, clubs and institutions) must ensure that their monthly consumption of municipal drinking water is reduced by 45% compared to the corresponding period in 2015 (pre-drought). All agricultural users must ensure that their monthly consumption of municipal drinking water is reduced by 60% compared to the corresponding period in 2015 (pre-drought). The operation of spray parks is prohibited. No new landscaping or sports fields may be established, except if irrigated only with nondrinking water. For users supplied with water in terms of special contracts (notarial deeds, water service intermediaries or water service providers), the contract conditions shall apply.

34 RESTRICTIONS APPLICABLE TO NON-RESIDENTIAL CUSTOMERS Failure to comply will constitute an offence in terms of the City s Water By-law, 2010 (or as amended). The accused will be liable to an admission of guilt fine and, in accordance with section 36(4), an installation of a water management device(s) at premises where the noncompliance occurs. The cost thereof will be billed to the relevant account holder. Customers with good reason for higher consumption need to provide the City with motivation to justify their higher consumption.

35 WHAT CAN INDUSTRY DO?

36 INNOVATE More than 70 Industries are collecting treated effluent at WWTW and standpipe points.

37 INDUSTRY DOING ITS BIT THESE COMPANIES ARE LOOKING AT ALTERNATIVE SOLUTIONS, IMPLEMENTING WATER SAVING MEASURES, GOING OFF THE GRID: Old Mutual Rabie Vineyard Hotel WWF EVENTS

60 Water use (kl) Saving from 2011 (%) Our Story... Importance of baseline data % % % 40% 20% % Consumption (kl) Saving (%)

61 How to reduce. 1. Low-flow showerheads choose carefully! 2. Low-flow tap aerators which application? 3. Hold-flush toilets easy to retrofit 4. Waterless urinals increases maintenance 5. Turned off irrigation only during drought 6. Awareness/behaviour input and feedback

62 Water use (kl) Saving from 2011 (%) Our Story saving 2017 saving Payback: 9 months! Waterless Urinals; Irrigation turned down 60% Irrigation turned back on Irrigation turned off due - drought Hold-flush toilets, lowflow taps, lowflow showers 100% 80% % % 40% % % 0% Consumption (kl) Saving (%)

63 Our story Gaining acceptance can take time ideas presented in 2016 only approved in Nov 2017 We experiment before recommendation to clients various fixtures trialled and mistakes were made Iterative process not one size fits all, trial and error Business continuity is a major incentive bottom line is usually primary concern Let s make the most of this crisis

64 JG Afrika, Cape Town Office Reduce Reuse Alternative Sources

65 Rainwater harvesting

66 Rainwater harvesting Rainwater tanks can look good! Business continuity saves millions pays back the system many times over

67 Water Masterplan Stellenbosch Campus

68 Understating water use is important no one size fits all

69 Stellenbosch Campus Water Plan Reduce Principles stay the same regardless of project scale Interventions change Reuse Alternative Sources

70 Stellenbosch Campus Water Plan Select carefully: 35% of buildings save 90% of usage No. Phase Cumulative Saving (%) Payback (yr) - Current Reduce use 45% Greywater 55% Rainwater 65% Borehole 85% River and Dam 100% 2-5

71 Key findings Phase 1: REDUCE Good baseline data is critical No one size fits all subtle complexities Easier to save 50% than to find 50% more new water Business continuity priceless Biggest savings - Reduce phase Not all water fixtures are equal. Behavior change is critical Phase 2 and 3: RE-USE Fit for purpose use drinking water flushing toilets
