The Future of STEM: Empowering Women

During Engineers Week (February 16-22), a celebration of the diverse and innovative field of engineering, it’s important to reflect on not only how far we’ve come, but the journey still ahead, particularly when it comes to empowering women in science, technology, engineering, and mathematics (STEM). The theme this year, which aligns perfectly with our values at Tata & Howard (T&H), encourages innovation, leadership, and equality. Women in STEM are not just breaking barriers; they’re rewriting the rules. And at T&H, we’re proud to be part of that journey, especially when it comes to water systems engineering.

In a profession that has traditionally been male-dominated, our emphasis on employee ownership, particularly through our Employee Stock Ownership Plan (ESOP), has further helped level the playing field. By offering employees a stake in the company, we empower individuals (particularly women engineers) to shape the future of the firm and the industries we serve. This sense of ownership is essential for innovation and reflects the values of equality and collaboration that define our company culture.

A Legacy of Supporting Women in Engineering Leadership

Over the years, T&H has consistently been at the forefront of promoting gender equality in the workplace, especially within the engineering sector. The leadership team is composed of accomplished women who are shaping the future of water system engineering while also fostering an environment where the next generation of female engineers can grow. These trailblazers not only bring years of technical expertise to the table but also serve as mentors and role models for young engineers aspiring to follow in their footsteps.

At the heart of our engineering teams are women who bring extensive experience, cutting-edge technical skills, and a passion for innovation. These women are not only integral to the success of the company, but are also key players in transforming the water systems of the future, working tirelessly to ensure that the communities we serve have access to safe, reliable water systems.

Women Who Are Driving Change at Tata & Howard

With Girl Day on February 20 during Engineers Week, it’s the perfect moment to highlight some of the incredible women leading the charge here at T&H. These women are not only tackling complex engineering challenges, they’re also inspiring the next generation of engineers, especially young women who are considering their future careers.

Our team is fortunate to have several outstanding women engineers who are leading by example and pushing the boundaries of what’s possible in the water engineering field.

Karen Gracey, serves as our Co-President with over 27 years of experience. Karen is a standout leader at T&H, specializing in water system design and hydraulic modeling. She is experienced in WaterGems and InfoWater software and her work on the Capital Efficiency Plan methodology has been integral to the development of water systems across New England. As a member of Tata & Howard’s Board of Directors and the NEWWA program committee, Karen is not only an influential figure within T&H but also a respected leader in the broader engineering community. Her ability to balance technical expertise with mentorship and leadership is an inspiration to the entire team.

Jenna Rzasa, our other Co-President, brings over 28 years of engineering experience and a wealth of knowledge in water system design, new water source development, and conducting water audits. As a board member and a leader in her field, Jenna has become a trusted advisor on complex water system projects and is a key driver of our Capital Efficiency Plan initiatives. Her contributions have helped municipalities across New England optimize their water infrastructure, ensuring that communities are served by sustainable and resilient water systems.

Justine Carroll’s expertise in water system hydraulic modeling, design, and construction has been invaluable to T&H’s projects over the last 19 years. With certifications in WaterGEMS and InfoWater modeling software, and her position as Vice President, Justine has also contributed to the development of cutting-edge environmental solutions. Her educational background, including both a BS and MS from Tufts University, has prepared her to tackle complex engineering challenges with both precision and innovation.

Allison Shivers is a standout Project Manager specializing in wastewater engineering who brings over 15 years of experience to our team. Her work evaluating wastewater collection systems and improving wastewater treatment facilities has had a significant impact on the infrastructure of many of our local communities. In addition to her engineering expertise, Allison — like most of our female engineers — is a mother who prioritizes work-life balance, modeling for younger women in the field that it is possible to pursue a fulfilling career while also nurturing a family.

Molly Caruso, with 11 years of engineering experience, brings a unique perspective to the team as a Project Manager. Specializing in water distribution, Molly’s passion for environmental sustainability and her technical expertise help shape T&H’s approach to solving water infrastructure challenges. As a working mother, she exemplifies the flexibility and support that the company provides to ensure women can thrive both professionally and personally.

Kathryn (Katie) Carreira is a Project Manager with laser-level focus on hydraulic modeling, water infrastructure design, and water treatment. Her contributions over the last nine years to our water infrastructure projects have been invaluable, particularly in ensuring the design and safety of critical water systems. As a young engineer, Katie is part of a new wave of female
professionals who are shaping the future of water engineering.

Empowering the Next Generation of Female Engineers

Tata & Howard’s commitment to women in STEM is not just about supporting the women who are already leaders in the field but also about inspiring the next generation of engineers. Initiatives like Girl Day offer young girls the opportunity to explore engineering careers and see firsthand the impact that engineers—especially women—can have on the world. Through programs like these, we aim to break down the barriers that may deter young women from pursuing careers in STEM, showing them that there is a place for them at the table.

Our company’s focus on employee ownership through the ESOP program plays a significant role in encouraging women to step into leadership positions. Employee ownership fosters an environment where everyone — regardless of gender, race, religion, or sexual preference — has a voice and an opportunity to shape the direction of the company. This sense of ownership helps cultivate not only confidence, but also collaboration and a sense of responsibility for not
just the company’s success but also for shaping the future of the industries we serve.

The Road Ahead

As we celebrate Engineers Week and Girl Day, it’s clear that the future of STEM is bright, particularly for women. At Tata & Howard, we are proud of the progress we have made in fostering an inclusive and empowering environment for women in engineering, but we know that there is still more work to be done. We remain committed to ensuring that the future of STEM is one where women’s voices are heard, their contributions are valued, and their leadership is celebrated. Together, we can continue to break down barriers and inspire the next generation of women engineers to achieve their full potential.

International Women’s Day 2019

Women in Engineering


For the last 108 years, International Women’s Day (IWD) has taken place on March 8 all around the world. IWD is a global day of recognition celebrating the social, political, economic, and cultural achievements of women.
While the personal meaning of this day may vary, the global theme of equality and celebration resonates with a powerful force. From big cities and sprawling country sides, to tiny villages and corporate organizations, women and men alike are showing their support for all the women who make a difference each and every day.

The Women of Tata & Howard

At Tata & Howard, we feel particularly lucky to work alongside such talented and fantastic women. Of the 60 individuals who make up our firm across seven locations, 22 (or 37 percent) are women. On top of that, our two co-presidents are also women. Karen L. Gracey and Jenna W. Rzaza have more than 43 years in combined engineering experience, and go above and beyond to lead our team to its fullest potential. In an industry that has been predominantly dominated by men for the last several centuries, it prides us to see the strides and achievements being made within our company and others like us around the world.
