Rainwater
Rainwater management has become a major challenge for urban and industrial areas, which are increasingly exposed to more intense and frequent rainfall events. Across Europe, data shows that cities must adapt their infrastructures to manage flow rates, discharge quality and the potential reuse of rainwater. Combined systems and low-impact infiltration solutions are gaining importance.
Rainwater collection and treatment networks must be designed to absorb very large volumes of water, reduce flood risks, limit pollutant loads entering natural environments, and enable the recovery or reuse of these waters.
Technical solutions and performance requirements
Equipment used in this field such as control valves, infiltration systems or storage units must meet specific requirements:
- ability to handle peak flows and high volumes during heavy rainfall events
- tightness and long-term durability, even under aggressive conditions (polluted runoff, mixed rainwater and industrial water)
- compatibility with retention or reuse solutions to reduce pressure on wastewater systems. For example, “sponge city” designs or green roofs can reduce runoff by up to 75% on some buildings.
With its strong expertise, BAYARD provides tailored solutions for rainwater applications, including control valves, non-return valves, diversion systems and monitoring equipment. Our products ensure safe, high-performance water management that meets both infrastructure protection needs and rainwater valorisation objectives.
