Welcome, TerraSite Design, to the Interstate Engineering Team!

Pools & Aquatics Planning, Design, and Construction

Building Community, Engineering Fun.

At Interstate Engineering, we believe aquatic spaces are more than just water; they’re where communities come together. From splash pads to multiuse water parks, we work with cities, park districts, and facilities to design and deliver aquatic environments tailored to your financial, operational, and community needs.

With decades of experience and numerous successful projects across the Upper Great Plains, our team understands the environmental and logistical factors unique to this region and your community. Many facilities are aging, difficult to maintain, or no longer meet the needs of the people who use them. We help municipalities overcome these hurdles by guiding them through the planning and design process, identifying practical, low-maintenance solutions that work long-term.

By staying current on the latest design trends, technologies, and equipment options, we strive to meet the unique requirements of each project. We deliver custom, future-ready systems that streamline operations and reduce strain on local staff and budgets.

We are committed to aquatic facilities from concept through construction as well as maintenance planning and operational support. Our reputation as a trusted partner makes us a go-to choice for aquatic facility development.

Let’s Bring Your Aquatic Vision to Life.

Whether you’re updating an aging facility or dreaming up a new one, we’re ready to help.

We're Proud of What We Do

Work With Us

1

Evaluate & Plan

We start by assessing your existing facility or site, identifying issues, and defining your goals. This includes evaluating mechanical systems, safety needs, and community priorities, then developing realistic budgets and funding strategies.

2

Design & Visualize

Our team creates tailored designs focused on safety, accessibility, and operational efficiency. Using CAD, 3D modeling, and virtual reality walk-throughs, we can help you see your facility before construction so you make confident decisions.

3

Build & Support

We provide guidance, answer technical questions, and work closely with contractors to ensure the project is built to specification, code, and safety standards. After completion, we continue to support communities through inspections, system training, and long-term maintenance planning, ensuring each facility operates smoothly for years to come
