Access
to clean, reliable water services is not a guarantee for
all U.S. communities. The challenges related to such service failures
have inequitable impacts on low-income neighborhoods and communities
of color. How equity is defined and operationalized in water-sector
infrastructure is inconsistent across the literature and in practice.
This inconsistency can make it challenging to hold utilities accountable
for unequal distributions of burden (e.g., lack of affordability and
poor water quality). As such, this study seeks (1) to determine how
equity is currently defined and used in the water sector, (2) to develop
a definition that can be used to incorporate equity into water-sector
infrastructure, and (3) to understand attitudes toward equity of water-sector
professionals. We conduct a qualitative analysis of relevant media
articles, survey responses, and semi-structured interviews with water-sector
professionals. We propose a definition of equity in water that is
informed by the results of this analysis. Categories emerge that can
be leveraged to create vertical equity solutions, such as addressing
intermittent supply and water-quality issues in vulnerable communities.
The definition may be used to operationalize, metricize, and benchmark
equitable water policy and practices at all levels of decision making
(e.g., federal, state, and local) to ensure an equitable water future.
