Whether your project requires flood control, irrigation regulation, hydropower optimization, or environmental water management, HTE delivers robust solutions that help clients achieve their operational goals with confidence.
A rubber dam is a flexible, inflatable bladder anchored across a waterway, designed for dynamic water level management. When water needs to be held back—for irrigation or power generation—the bladder is inflated with air or water, creating a barrier. This raises the upstream water level, effectively forming a reservoir.
Conversely, for flood control or to allow unobstructed flow, the bladder is rapidly deflated. It flattens against the riverbed, allowing water to pass freely over it. This flexibility and quick operation make rubber dams a cost-effective and adaptable alternative to rigid gates, suitable for various water management applications.
