As the #1 Water firm ranked by Engineering News-Record, Tetra Tech provides innovative solutions for our clients’ water supply
and wastewater challenges. We work to capture, treat, and recycle water and extend the life of our freshwater resources.
Managing water supplies
through innovation
Tetra Tech designed a stormwater capture
project to improve water quality in the Los
Cerritos Channel in Lakewood, California. The
system uses smart, real-time controls to optimize
system capacity to avoid flooding and maximize
water quality, infiltration, and opportunities
for irrigation use. An air-inflated rubber dam
diversion system will direct runoff to a pretreatment system to remove sediment and
pollutants. Water will be conveyed into a storage
and infiltration facility. The water in storage will
be used to meet the 9.5-million-gallon annual
irrigation demand at the city’s Bolivar Park. Watch
the project video at tetratech.com/bolivarpark.

Capturing stormwater
to improve beach water quality
Tetra Tech used advanced water quality modeling
tools to design a stormwater capture system
to improve beach water quality and increase
drought resiliency in Santa Monica, California.
At the Santa Monica Pier Storm Drain, a flow
diversion structure will redirect stormwater and
urban runoff from the 106-acre pier watershed―
that would otherwise flow into the ocean―into a
subsurface facility with a storage capacity of 1.6
million gallons. Water diverted from the Santa
Monica Pier and Pico-Kenter Drainage Basins will
be treated and reused for other purposes such
as irrigation or toilet flushing. Watch the project

Supporting EWB to provide clean water around the world
“Tetra Tech—through its
financial support and
the volunteerism of its
employees—is a crucial part
of the Engineers Without
Borders global movement
that is creating change
through education and
the implementation of
sustainable engineering
projects.”
Cathy Leslie, EWB-USA Executive
Director and EWB International
Executive Committee Member
As part of Tetra Tech’s longstanding support to
EWB, the company’s 50th Anniversary Global
Clean Water Fund grant program supported EWB
organizations worldwide to help communities in
need obtain safe, clean water supplies.
Tetra Tech reviewed dozens of submissions for
worthy water-related projects from 10 countries
around the world, from Mexico to Malawi. Tetra
Tech selected six projects to fund, each of which
meets an identified need of the local community,
involves community members in the project,
and ensures long-term
sustainability of the project
or technology.

“Tetra Tech created the
Global Clean Water Fund
to commemorate its 50th
Anniversary, building on
its legacy of leading with
science,” said Dan Batrack,
Tetra Tech Chairman
and CEO. “We were very
impressed with the quality
of applications we received
and the dedication of the
project teams to identify
innovative approaches to
solving community water
challenges.”
The grants will help bring
safe water supplies to
communities in poor and
18
underserved areas of Brazil, Cameroon, India,
Malawi, Mexico, and Timor Leste. Projects include
supply infrastructure such as cased water wells
and rainwater harvesting, filtration systems, and
training programs. Dedicated teams from EWB
organizations in Australia, Brazil, Cameroon,
Canada, India, and the United Kingdom lead the
projects in conjunction with local community
members and organizations.

Last year, Tetra Tech made significant progress toward achieving our sustainability goals set in 2010. Our revenue increased by 12 percent and our headcount
increased by 19 percent from the previous year, and we reduced our GHG emissions an additional 3 percent, resulting in a 40 percent reduction since we
initiated our Sustainability Program. To set new 2020 goals, Tetra Tech’s Chief Sustainability Officer, in partnership with our Corporate Sustainability Council,
identified and recommended updated metrics and targets for our Sustainability Program, consistent with our focus on projects, business practices, and
community engagement. Tetra Tech’s 2020 plan includes overarching goals that emphasize and recognize our focus on growth in revenue and headcount and
continued reduction of our GHG emissions to achieve a 50 percent reduction since program inception.
These resulting goals for 2020 are included in the tables on the following pages.
