Water Systems

Water is essential, and so is the infrastructure that delivers it. At SEMA, we build water infrastructure that lasts, from supply networks and wastewater treatment facilities to storm drainage systems and flood control solutions. With decades of experience, we take a direct, problem-solving approach, combining engineering know-how, innovative construction methods, and real-world expertise to deliver efficient, cost-effective, and dependable water systems.

From deep excavations and intricate piping to massive reservoirs and pump stations, we self-perform key work to keep quality high and timelines on track. By working side by side with engineers, municipalities, and environmental experts, we make sure every system is built to perform—safely, precisely, and with long-term resilience in mind.
