UNICEF sells restaurant tap water for $1 — 40 days of clean water per dollar
Droga5's 2007 Tap Project turns free tap water into a donation: diners pay $1 during World Water Week and UNICEF buys a child 40 days of clean water.

What it had to solve
UNICEF wanted a simple, mass fundraising mechanism for its clean-water programs. Tap water is free and taken for granted, so the challenge was to turn that invisible luxury into a donation moment at the dinner table.
How it works
In March 2007, on World Water Day, New York City diners were asked to pay $1 for the tap water their restaurants normally served free. The Tap Project, created by agency Droga5 with UNICEF and the City of New York, directed the money to UNICEF's clean-water programs, and every dollar was described as providing a child with 40 days of clean drinking water.
The idea worked by making an invisible luxury visible. Most diners never thought about the free water on the table; the campaign pointed at it and said this exact thing is scarce elsewhere. The ask was small, the exchange was immediate, and the moment of drinking water became the moment of giving.
It scaled quickly because it added a line to an existing transaction instead of building new machinery. About 300 New York restaurants took part in 2007; by 2008 more than 2,300 restaurants nationwide had joined, with agencies including Publicis, Saatchi & Saatchi, TBWA\Chiat\Day and Wieden+Kennedy donating creative services.
By 2009 the project had reached all 50 states and spread to other countries, and UNICEF kept returning every March for World Water Week. The campaign turned a restaurant habit into a national fundraising ritual for clean water.
Why it lands
- It monetized something diners already received free, so the donation felt effortless and landed exactly when they were enjoying the water.
- It made the cause tangible: one dollar mapped to 40 days of clean water for a child, an exchange anyone could understand immediately.
- It turned restaurants into fundraising channels with no new infrastructure, which is why it could jump from 300 outlets to 2,300 in a year.
- World Water Day gave it a built-in ritual and deadline, so the campaign had a natural annual rhythm instead of fading away.
What it did
The 2007 pilot started with about 300 restaurants; within two years the project reached all 50 U.S. states and spread internationally, with more than 2,300 restaurants participating in 2008. UNICEF repeated the campaign every March during World Water Week, and each dollar was described as giving a child 40 days of clean drinking water.
What you can take
Put the ask where the value is felt: the donation happened when diners drank free water, so the cause felt concrete and the ritual scaled without new infrastructure.
Since then
UNICEF repeated the Tap Project every March through World Water Week, adding celebrity promotions, campaign films such as 'Water Balloons' (2010), and later a mobile app that let people donate time away from their phones. The restaurant ritual became a template that spread internationally, and tap water — long an invisible freebie — became a recognized fundraising channel for clean water programs.
