In the quest for more efficient water management, Grundfos has emerged as a key player, particularly in its partnership with waterworks companies like Essbio-Nuevosur in Talca, Chile. This collaboration has led to remarkable improvements in water supply and energy efficiency, showcasing the potential of advanced pumping technology.
The Challenge in Talca
Talca, a city with a growing population of over 300,000, faced significant challenges in its water distribution system. As the suburb of Tejas Verdes expanded—now home to around 10,000 residents—demand for water surged. The existing system struggled with inconsistent pressure, leading to pipe breaks, water loss, and inadequate supply at times. Recognizing the need for a solution, Essbio-Nuevosur set ambitious targets to reduce energy consumption and cut down on non-revenue water.
The Grundfos Solution
In response to these challenges, Essbio-Nuevosur turned to Grundfos and its innovative Demand-Driven Distribution (DDD) system. This technology allows for real-time adjustments to water pressure based on actual demand rather than relying on fixed schedules. By implementing the DDD system, the company aimed to enhance service during peak hours while simultaneously reducing operational costs.
The installation involved a sophisticated setup, including four CRE90 vertical multistage centrifugal pumps managed by a CU352 controller. This configuration ensures efficient pressurization and reliable water supply across the network.
Impressive Outcomes
The results of the DDD system have been transformative. After 18 months, Essbio-Nuevosur reported a 32% reduction in energy consumption and a 3.3% decrease in non-revenue water. The system's ability to respond to sudden spikes in demand—such as during events like the World Cup—has proven invaluable. Real-time monitoring allows for immediate adjustments, maintaining stable pressure and consistent service for residents.
Moreover, the DDD system has led to a notable decrease in pipeline breakdowns, with operators reporting no major issues since its implementation. This reliability not only reduces maintenance costs but also allows staff to focus on other essential tasks, enhancing overall operational efficiency.
Advantages of the DDD System
The implementation of the Grundfos DDD system has provided several key benefits:
- Energy Reduction: Achieved a significant 32% decrease in energy consumption.
- Lower Non-Revenue Water: Reduced losses by 3.3% in the first six months.
- Stable Pressure: Maintained consistent pressure across the water distribution network.
- Fewer Breakdowns: Eliminated pipeline issues, leading to lower maintenance needs.
- Immediate Responsiveness: Adapted to unexpected demand peaks seamlessly.
Looking Ahead
Given the success of the pilot project in Tejas Verdes, Essbio-Nuevosur is now considering the expansion of the DDD system to 51 additional plants, potentially benefiting over a million households. This initiative not only reflects the confidence in Grundfos technology but also highlights the growing trend of adopting smart water management solutions.
