The average Dutch person uses 118 litres of drinking water per day. Over 40 percent disappears in the shower. At the same time, the population is growing, demand is rising and drinking water sources are under pressure from drought and pollution. Supply and demand are diverging, and that gap will only widen.
The National Action Plan for Drinking Water Conservation sets a concrete target: 100 litres per person per day. Not a symbolic figure, but the threshold below which the system remains viable in the long run.
"'There is a whole world behind it of extracting many litres of water, large purification plants and more than 120,000 kilometres of pipes to get it to people's homes. This drinking water is under pressure. I think it is good if people become more aware of the value of drinking water and handle it more carefully."
The communication problem behind the transition
Governments and water companies are investing in new sources, better protection of existing ones and technical innovation. But infrastructure does not resolve the problem if behaviour does not change. And behaviour change at national scale demands more than public information.
That is the real challenge. Drinking water conservation concerns everyone but feels urgent to no one. The tap works. The water is cheap. The consequences of excessive use are diffuse and distant. Under those conditions, a rational message about litres and statistics has little effect.
The campaign 'Word geen Douchebag. Fris in 5 minuten' opts not for guilt but for recognition. Dutch people see their own behaviour reflected, not a problem attributed to them.
From awareness to norm
The strategic challenge here is the same as any long-term behaviour change programme: isolated reach does not shift behaviour at scale. What does is the normalisation of a new standard, until five minutes in the shower feels self-evident rather than a sacrifice.
That requires coordinated action across government, water companies and the wider public. A national campaign is one instrument. The harder work is institutional: embedding water conservation into policy, building standards and the way utilities communicate with customers over years, not weeks.
For organisations navigating long-term transitions in energy, in climate, in public health, this is a familiar challenge. The facts are not in dispute. The infrastructure exists. What is absent is the shift in collective behaviour that makes the system sustainable. At that point, communication strategy is not a support function. It is part of the transition itself.
