Rainwater centre

Rainwater centre

Rainwater centres take complete control of the system for a rainwater harvesting plant. The electronic control system controls and regulates the entire operation. The change-over valve opens with sensor control at low level in the cistern and ensures that mains water is fed into the utility water supply network.
