Meet our design team and VSplash

Our Role as Designers


Our project managers are registered landscape architects with extensive experience in the splash park industry. The project manager will be the key contact throughout the development process and will lead all design and construction administration.


The civil engineering department prepares the site grading and drainage. They work with the project managers to provide a splash park that fits into the overall park plan. Our engineers also review existing site infrastructure and prepare all piping plans.


Our mechanical team works to develop the distribution system for the water to the selected splash park components. Our staff includes technicians who are adept at re-circulation system design and can guide each project from concept to commissioning.
