27|2|2018 – CAPE TOWN DROUGHT UPDATE
Cape Town’s tough water-saving regime has seen Day Zero be pushed back once again, to 9 July from an earlier date of 4 June. This announcement came off the back of a 10 billion litre water donation from the Groenland Farmers Association. Residents of Cape Town have collectively cut consumption by more than half in the last 3 years. Last week water consumption averaged 523ML per day, falling far short of the target of 450ML per day.
Cape Town water crisis snapshot:
- Cape Town’s cumulative dam levels are sitting at 24.1%, down 0.5% from last week
- The City’s main water source, Theewaterskloof Dam is at just 10.9% capacity, down 0.7% since last week.
- The City claims its progress in securing alternative water sources through desalination, recycling and groundwater is at 62%.
Water scarcity affects more than 40% of the global population, underlining the urgent need for large-scale solutions to ensure long-term water security. Cape Town requires around 500ML of water per day to supply its citizens with 100L per person per day. Cape Town has begun down the road of desalination- the process by which salt and other impurities are removed from seawater to produce potable water.
We looked at Israel as an example of where desalination is being utilised in a cost-effective way.
Much like Cape Town, Israel is faced with limited rainfall and a gruelling climate. In order to secure water sources, Israel has increasingly relied on desalination since the 1960s when the world’s first plant was built.
