Drink Tap: A Multi-Sector Effort to Promote Water Access and Intake in San Francisco Parks to Improve Beverage Intake and Promote Health
Sugar-sweetened beverages (SSBs) are a major caloric source and the largest source of added
sugars in the American diet. While many cities around the country have adopted anti-SSB
policies such as soda taxes to reduce SSB intake, there has yet to be any studies to evaluate
if the effects of these taxes, coupled with increased water access and promotion effort can
lead to decreased sugar sweetened beverage consumption and increased water consumption. This
quasi-experimental study evaluates how implementation of SSB taxes, installation of new water
stations, and a multicultural water promotion campaign in parks impacts beverage intake in
these settings as compared to soda taxes alone.

Consumption of water, in place of sugar sweetened beverages (SSBs), can help prevent obesity
and dental carries. While drinking water is associated with these and many other positive
health outcomes, many do not meet the recommended dietary intake of water. This is more
profound in low income and minority communities that are more likely to drink less water and
drink more SSBs. School-based water promotion interventions have shown that improved access
to clean drinking water coupled with promotion leads to increases in water consumption and
improved health outcomes. No studies have studied the impact of similar strategies on
beverage intake and health in parks and public spaces. Parks are an inconspicuous and widely
utilized public space, with the majority of Americans going to a park in the last month. This
study's central hypothesis is that visitors in parks with SSB taxes coupled with increased
access to appealing drinking water and rigorous promotion of its consumption will be more
likely to drink water and less likely to drink SSBs, compared to visitors in parks with only
SSB taxes. This quasi-experimental study makes use of naturally-occurring policy changes in
the San Francisco (SF) Bay Area to disentangle the impacts of anti- SSB policies, water
station installation, and multicultural water promotion efforts, using control groups to
isolate the effects of anti-SSB policies alone or no intervention. This study will analyze
beverage consumption in 10 SF parks that received new water stations and a multicultural
water promotion campaign compared to 20 matched control parks (10 parks SF and 10 parks in
Oakland) with only SSB taxes.
