Our education collaborators are working on programs to implement the app in STEM classrooms and clubs for kids and teens nationally and around the world to learn about how engineering shapes our every day lives. Kids and teens in these programs will be invited to connect with engineers through the app so they can meet and interact with professionals in their fields of interest. Please contact us to learn more about the program and how you can participate.

Our Commitments

We give back to our community

Alan Plummer supports the community in many ways, including partnering with the Texas American Water Works Association for an Environmental scholarship for students studying Civil or Environmental Engineering within a ABET accredited engineering program or Scientist degree in Environmental Life, Water, Biology or related field and attending a Texas University.

In addition, Since 2009, APAI employee donations and company match funds have paid for five new water wells located in rural Guatemalan, Ghana, and Nicaragua communities that previously had no access to clean water. APAI employees have traveled to Guatemala and Nicaragua to participate in completing the new community water wells

This is Our Story...

Alan Plummer Associates, Inc., began in Arlington, Texas. Using the living area as an office and setting up a drafting table in a bedroom, the firm began its operations. Within six years, the firm transitioned its service as primarily a study firm to a study and design firm, with an emphasis on water and wastewater treatment.
