According to media reports, local government in Cape Town, South Africa, has passed a law to say that houses being sold need a certificate from a plumber.
The certificate will verify that the property has no plumbing problems. If there are problems - even as simple as dripping taps – they need to be fixed before the property can be sold.
The law is aimed at cutting water waste as there is a real shortage of water in the Western Cape area of South Africa. Other cities are expected to pass similar laws, according to the local media.
As the UK begins to feel the effect of climate change, could we see similar laws enacted here? It does not seem likely. Not yet.
