Hydraulic & Mechanical Engineering
Detailed pipe sizing, pump curve selection, water turnover rates, and pressure drop analysis tailored to complex, multi-tiered waterfall displays.
Landmark Architecture & Restoration
Government Hill & Kerth Fountain
Perched majestically below the historic World's Fair Pavilion in Forest Park (St. Louis, USA), Government Hill features one of the most iconic civic water features in North America: the Kerth Fountain and its cascading reflecting pool. Originally constructed in 1930 following the historic 1904 World's Fair era, this landmark fountain system underwent a multi-million-dollar modernization project to preserve its heritage while upgrading its hydraulic and electrical infrastructures to modern municipal engineering standards.
As premier engineering consultants and equipment suppliers for commercial architectural water features, Hydro Dramatics partnered with lead design firm HOK to deliver full hydraulic design, electrical engineering, custom equipment fabrication, and control technology. Our team successfully modernized the system to handle heavy continuous operation while adding vibrant RGB LED lighting effects to highlight civic events.
