Background

Formed in 1966 as a membership-owned cooperative, Iredell Water provides essential services to over 10,000 customers, 94% residential. After decades of reliable operation, their aging AMR system was beginning to falter. Leaks went unnoticed as meter readings grew erratic. Crews wasted precious hours crisscrossing rural roads chasing false alarms. It became clear that a new solution was needed to restore reliability across Iredell's sweeping service area.

Iredell’s General Manager and CEO, Danny Sloan wanted to find a solution that was not only durable but also capable of mastering challenging rural topography. Their infrastructure was scattered, but a robust metering network could unify it into a singular nervous system.

The challenge

With water districts that cover vast rural areas, Iredell Water Corporation faced distinct challenges in monitoring its water infrastructure. Detecting and maintaining leaks was complex, with meters scattered over miles. They needed a solution that was not only durable but would future-proof its water treatment system.

To transform their system, some key questions had to be addressed: How could they get real-time insights into water usage? How could they quickly detect leaks and effectively handle water-related maintenance issues? Would it be possible to manage and monitor the far-reaching distances between water meters more efficiently?

Answering these questions and putting the right solutions into action will not only turn things around for Iredell Water but could also pave the way for other rural water districts wrestling with similar dilemmas.

The solution

Water districts that cover vast rural areas face distinct challenges when it comes to monitoring and managing infrastructure. Detecting and maintaining leaks becomes complex, with meters scattered over miles of isolated backroads and varied terrain. Iredell Water Corporation, a nonprofit organization that caters to the rural foothills of North Carolina's Piedmont region, is no stranger to these obstacles.

To tackle it’s infrastructure challenges, Fortiline presented Kamstrup’s robust AMI system. This would allow them to remotely read water meters every three hours, significantly reducing the time, effort, cost, and energy previously spent on manual meter readings.

Fortiline introduced Iredell to the Kamstrup solution at a rural water conference in North Carolina and facilitated discussions on their robust AMI system would handle Iredell's vast 450-mile service area, skillfully navigating across valleys, forests, and farmlands.

In the early stages, surprised by the range and capability of the system, Danny pushed the limits by reading a meter from 12 to 14 miles away, right at his kitchen table. The system's resilience was further tested when an F1 tornado passed about 100 feet from a collector tower. Yet, the system continued to function smoothly, showcasing the durability and quality of the product and as well as installations.

Key results

The newly implemented AMI system allowed Iredell to read water meters every three hours, significantly reducing the time, effort, cost, and energy previously spent on manual meter readings. Coincidentally, the project was completed five months ahead of schedule and 5% under budget, with only 12 collectors installed instead of the initially planned 18.

Iredell Water recognized the numerous benefits of AMI meters and decided to expand their use beyond the original project scope. The collaboration between Iredell Water, Fortiline and Kamstrup was very successful, demonstrating a great combination of durability, technical expertise, effective time management, and overall effectiveness in providing water management services in rural areas.
