How Cape Town compares to other international and African cities in the water sector

• Approx 80% of customers have reticulated water and sewerage services.
• If Cape Town were in the USA, it would be in the top 10% water utilities by size.
• Big challenges do exist:
• A large number of informal settlements who have the inconvenience and inadequate supply.
• Water quality issues in rivers and sewer spills.
• In Africa demand for water is increasing, almost tripling over 25 years.
• Supply is deteriorating due to climate change and water quality.

Key takeaways from beating the water crisis of 2018

• 4 major drought events over the past 100 years.
• 2014 - 2018 drought was 1 in 590-year rainfall event.
• City gets 98% of the water from surface water (dams that rely on rainfall).
• Reduced water demand from city from around 1000 million litres per day to 500 million litres per day.
• The partnership between the City and their customers.
• City used leak detection, improved metering, pressure management, higher tariffs, major communications campaign.
• Each citisen played their part. Using the smallest amounts they could. Flushed their toilets less.
• Agriculture played their part, wine farming reduced their demand by approx 60%.
• City of Cape Town won an award from the International Water Association for the number one water saving city in the world: Reduced 55% of demand over 3 years.

In hindsight, what the City would have done differently to avert the water crisis of 2018

• Over-reliance on surface water is their biggest vulnerability.
• Over the next 20-30 years predicting 30% reduction in surface water supply due to climate change.
• Perth example: 85% reduction of rainfall in their dams over past 50 years.
• Keep demand down: Target 130l per capita per day.
• Alternative water supply: Groundwater, reused water, desalinated water, and efficient use of water.
  

5 commitments of the City of Cape Town water strategy

• Safe access to water and sanitation for all.
• Wise water use.

How these commitments will be met and against what indicators and schedule

• R40 billion capital programme over next 10 years. Main focus on bulk water, wastewater and reticulation
• Focus currently is on building capacity within the department to build on these measures.
• Goal of water resilience by 2030. Mike explains how.
• Goal by 2040 to revitalise whole supply and clean river systems. Mike explains how.

Progress made to date (June 2021)

• Development of this water strategy together with implementation p
• The implementation plan has 8 transversal programmes spanning the whole department
• 4 new directors hired
• Restructured water and sanitation department. From 11 to 13 branches.
• Added customer service branch and capital & contracts management branch.
• Started the new water programme for alternative water supply, Mike explains.
• Temporary desalination and reuse plants.
• Extended groundwater exploration in Cape Flats aquifer, Table Mountain group aquifer and Atlantis aquifer. Drilled over 100 boreholes.
• Started clearing alien invasive species.
• Progress toward wastewater treatment works.
• Progress on sewer spills.
• Progress on maintenance.
  

Key technologies that can help achieve the Water Strategy’s vision

• Desalination
• Groundwater
• Reuse
• Wastewater
• Bulkwater
• Automated meter readings.
• IT systems to support their operations.
• Mike expands in more detail on above points.

Advice, opportunities and challenges for private sector to collaborate with the department

• R40 billion capital programme over next 10 years will mostly be contracted through private sector.
• Mike expands on the challenges and importance of collaboration.

Advice for cities grappling with water management

• Climate change is real.
• Build resilience: diversity sources, systems, staff.
• Build sustainability: Water quality impacted by sewage system and waster water treatment plants. Requires long term investment and collaboration with public and other stakeholders.
• Build inclusion: Informal settlements currently don’t feel part of the system. It creates unrest.
• Customer orientation: Trust is everything. Need a clear strategy, clear priorities, delivery and communication.
• Partnerships are key: Shared water strategy. Mike explains.
