How Cape Town can win support for the next round of water cuts
- David Olivier
Dams in South Africa’s Cape Town are half of what they were this time last year as the city continues to battle drought.
Last year’s shortage gave the city the driest summer in . Unless Cape Town has a miraculously wet spring, the summer of 2018 seems set to achieve some unfortunate new records.
Slowing down residential water use is obviously hugely important – of the city’s water. But to get residents to use less, the city’s management must get residents’ . This can only be achieved if and trust will only be developed when residents believe that the water authority is handling restrictions in a way that is necessary, effective and fair.
Australian researchers studying household water use found that people’s willingness to save water relates directly to the trust they feel in the local authority . The researchers also drew on a Mexican case study which found that residents who trusted the local authority in a town called Sonora during an eight-year drought were much more likely to .
These, and other studies, show that trust is built: when restrictions are equal to the ; when no one gets away with ; and when there is no favouritism towards .
Necessary, effective and fair
To build trust, the public needs to believe that restrictions are:
- Necessary: people must believe that the appropriate restrictions have been introduced at the correct time.
Queensland, Australia, for example, ran a campaign called “Target 140” during their . The aim of the campaign was to reduce water use to 140 litres per person per day. One of the greatest hindrances was that people had already endured two years of water restrictions. So they felt despondent that their best water saving efforts hadn’t been good enough and were reluctant to save .
But the campaign became a success after the Queensland water commission began showing residents how dam levels were dropping. It was able to convince customers that intensified water restrictions .

Effective: Residents can lose interest in conserving water if they believe that others are getting away with . A study on water restriction effectiveness in Los Angeles found that hardly any water was saved as long as water restrictions . People need to know that water restrictions are going to be .
-
Fair: Customers must trust that restrictions are applied appropriately to all water users. Case studies show that one of the most common complaints by residents is that others – particular groups or other residents – are the real . Queensland’s Target 140 Campaign managed to convince customers that severe restrictions on the residential sector, which used 70% of the water, . Reassuring residents of the is vital to sustain buy-in.
Is Cape Town building trust?
The City of Cape Town has done a good job in covering the bases when it comes to explaining water restrictions in terms of their necessity and their effectiveness. But it hasn’t done that well in explaining that water restrictions are being done fairly.
On the positive end of the scale, the city has done a good job in demonstrating that those who waste water are . This has been achieved through the naming and shaming of . And water management devices were installed on private properties that hadn’t curtailed .
But, on fairness, the city has only sporadically communicated the breakdown of water distribution from the 14 dams that supply its water, it’s rarely shown the breakdown of and scant mention has been made of restrictions placed on .
What can the city do differently?
Cape Town is emulating some of the best elements of a . Cape Town’s water saving target is close on half of Queensland’s, which was considered one of the most water-efficient communities in .
If Cape Town wants to beat Queensland’s target, it needs to spend the spring season convincing the public that restrictions are applied appropriately for all water users.
This means changing tack in its messaging. Up until now the dominant message has been aimed at convincing the public that restrictions are necessary and effective. Now it’s time to show that restrictions are fair.
This means showing exactly how water is allocated in the region, breaking down the distribution of water to various sectors and demonstrating that nonresidential sectors are also carrying their responsibility. This information is already in the public domain, but it needs greater emphasis.
A chain is as strong as its weakest link. Building trust, and getting the public to buy in to severely reduced water use over 2018, will be best achieved if the city can communicate the fairness of restrictions to fortify an otherwise robust campaign.
