Water Management
Water management is a critical component of our
business, and we continue to work with stakeholders
to improve our performance, while also reducing
consumption by:
also to the refining operations, as water is needed for
cooling, heating and processing.
• Taking a risk-based approach to water management
and integrating water strategy and water security
into our long-term planning and business processes,
under the supervision of management.
• At our Wilmington refinery, we are installing facilities
to use treated municipal wastewater to supplement
our cooling tower makeup water. Upon project
completion, we will save up to 420 million gallons
of potable water per year, equivalent to roughly the
annual amount consumed by 3,800 U.S. households. 23
• Engaging with local governments, industry
associations, suppliers and regulatory agencies to
develop innovative solutions in water management
and conservation in water-stressed areas.
• Assessing and managing regional water risks
through updated sustainability assessments.
• Ensuring compliance with water management laws
and regulations.
• Reporting on risks posed by water scarcity on each
facility, as applicable.
• Protecting existing water resources through sound
water management policies.
• Recycling and reusing water to improve efficiency.
Most of our water consumption takes place in our
refining operations. Based on the World Resources
Institute’s (WRI) Water Risk Atlas tool, Aqueduct, we
determined that only two of our 15 refineries are located
in regions with high baseline water stress. Reduction
and mitigation initiatives include the evaluation
of reused municipal wastewater for cooling tower
purposes and acquisition of secured water rights. Water
scarcity can be a risk not only to communities but
We have taken several steps we believe are necessary
to secure our operations in conditions of water scarcity.
• Our Three Rivers refinery recycles treated
wastewater for use in irrigation for hay production.
• Our Corpus Christi refineries pay into a broad
industry fund that provides water-supply security
and supports research and plans for the construction
of a desalination facility to serve industrial users.
• Our Welcome ethanol plant was one of the industry’s
first operators to achieve “zero discharge” of
wastewater by recovering and recycling process
water and stormwater.
• Process water and stormwater are treated as
necessary before discharging or reusing. Our
wastewater treatment plants are generally
comparable to and as effective as those operated by
most cities.
Water risk management is integrated into our
operational and long-term planning to mitigate
and reduce water risks.
