Overview
Retentech develops autonomous urban retention management systems that control distributed retention and flows in sewer networks to reduce runoff during heavy rainfall. The systems use remotely controlled actuators, gates and overflow edges that do not require a connection to the power grid, along with software for integration with customers’ monitoring systems. The company provides hydraulic analyses, urban catchment management system design and infrastructure supervision.
