Harnessing Nature's Bounty: Rainwater Reclamation System Powers Sustainability at Wilo USA

2.14.2024

In an era where environmental consciousness is paramount, businesses are increasingly adopting sustainable practices to reduce their ecological footprint. At Wilo North America’s headquarters located in Cedarburg, WI we have taken a significant step towards eco-friendliness with the implementation of a cutting-edge Rainwater Reclamation System as part of our broader sustainability initiatives.

The Initiative

In 2023, we embarked on a journey to enhance the sustainability of our operations, and one notable project stands out — the Rainwater Reclamation System. This innovative system is strategically designed to provide makeup water for our water pump test lab (Shown in Figure 1), showcasing a commitment to efficiency, resource conservation, and environmental responsibility.

How it Works

The Rainwater Reclamation System (Shown in Figure 2) ingeniously collects rainwater from 10,000 sq. ft. of roof surface area, channeling it into a carefully engineered filtration process. Before entering the system, the rainwater undergoes a thorough debris removal process, ensuring that it meets the highest standards of purity. The filtered rainwater is then stored in a substantial 4400-gallon holding tank situated within the test area.

The core functionality of the system comes into play when a sensor in the test pit detects a drop in water levels to a predefined minimum. This triggers our state-of-the-art QuantumFlo rainwater harvesting system to kick into action, pumping the stored rainwater into the test pit. This process not only ensures a consistent water supply for our test lab but also showcases the seamless integration of technology with sustainability goals.

Advanced Filtration and Disinfection

Once in the test pit, the reclaimed rainwater undergoes an additional purification process to meet the stringent quality requirements of our operations. A combination of cartridge filters and UV light disinfecting units (shown in Figure 3) ensures that the rainwater is free from impurities and pathogens. This dual-filtration approach not only guarantees the safety of the water but also maximizes the lifespan of our equipment.

Smart Control System

The entire Rainwater Reclamation System is orchestrated by a cutting-edge control panel featuring a user-friendly touchscreen interface. This intelligent system allows for real-time monitoring and control, ensuring that the rainwater reclamation process operates seamlessly. The touch screen also provides insights into water levels, and system status, and facilitates easy adjustments to meet the dynamic needs of our test lab operations.
