Denver Water brings back iconic conservation campaign

As water shortages intensify across Colorado, Denver Water has once again turned to creativity to encourage conservation, relaunching its iconic ‘Use Only What You Need’ campaign through a series of minimalist out-of-home installations. 

The latest campaign, titled ‘Water Is Missing’, arrives at a critical moment. Around 80% of Colorado’s water supply comes from snowmelt, but this year’s snowpack has fallen to its lowest level since records began in 1987. In response, residents have been urged to reduce their water consumption by 20%. 

Rather than relying on fear-driven messaging or guilt-based appeals, the campaign takes a subtler route, reminding people of water’s importance by visually removing it from everyday language. 

Billboards across Denver feature familiar phrases such as Pool Party, Car Wash, Wet T-shirt, Waterfall, Snow Cone and Watering Hole. In each execution, the water-related word is struck through with a simple orange line, leaving behind Party, Wash, T-shirt, Fall, Cone and Hole. 

The result is a striking visual metaphor that highlights what everyday experiences would look like without water. 

Each billboard signs off with the campaign’s enduring message: ‘Use Only What You Need.’ 

The campaign revives one of Denver Water’s most successful public awareness initiatives. The original Use Only What You Need programme helped reduce per-person water consumption by 21% in just three months and ultimately contributed to a 35% decline in water use over the following decade. 

By leveraging the scale and immediacy of outdoor advertising, the latest iteration demonstrates how OOH can communicate complex environmental issues through simplicity and restraint. There are no alarming visuals or lengthy explanations—just a few missing words that make the consequences of water scarcity instantly tangible. 

At a time when sustainability messaging often competes for attention, Denver Water’s campaign proves that some of the most impactful ideas are also the simplest, turning absence itself into the message.
