Download Case Study



Project Overview
Margate, Florida, is part of the Miami-Fort Lauderdale-Pompano Beach Metropolitan Statistical Area and home to nearly 60,000 residents. The city is known within the metro for offering exceptional quality of life and municipal services. This includes their Advanced Metering Infrastructure (AMI) for enhanced utility billing accuracy, as well as utility technical support.
Unfortunately, the existing AMI system aged, and consequently, billing accuracy waned. As a result, customer satisfaction decreased. Seeking a solution to restore their residents’ faith in their utility authority, the City of Margate consulted the Ferguson Waterworks Meter & Automation Group.
Challenge
The city was facing catastrophic AMI meter/MIU failure throughout its service area. Consequently, they sought an infrastructure-free AMI distributor and integration partner to help them optimize the utility system’s accuracy and also restore their customer’s satisfaction.
Products Utilized
– T-10® 5/8″ x 3/4″ – 2″ meters
– MACH 10® 3″ – 8″ ultrasonic water meters
– FirstNet Cellular AMI endpoint
– Neptune 360™ Smart Meter Data Management Software
Method
After reviewing the service area challenges and previous solution/partner issues, the Meter & Automation Group recommended deploying the Neptune FirstNet AT&T AMI Cellular solution for the entire service area. This solution relies on FirstNet, a nationwide communications network with always-on priority across all AT&T spectrum bands for first responders and public safety applications.
Installation contractor National Metering Service deployed 17,000 Neptune T-10 meters and MACH 10 ultrasonic meters with the FirstNet Cellular AMI endpoint. This meter network feeds information into the Neptune 360 meter data management platform to minimize the IT load on the municipal team.
Solution
The City of Margate chose Ferguson Waterworks and Neptune as their trusted partners because of our Meter & Automation Group’s extensive expertise, team resources, strong supplier/manufacturer partnerships, and product reliability.

In order to revitalize and meet stormwater codes, the abandoned parking area at the Shoppes at Fashion Square in Orlando, FL, required updates. With a permeable paving system and machine technology, we helped the client achieve their goals, save $1 million, and complete the project in just 10 days.
With solar panels in place and operational, an immediate and effective erosion control solution was imperative. Especially considering the panels were positioned next to channels, drip lines, and spillways.
After failed attempts to stabilize the earth at the Mt. Jackson Solar Farm, they required an immediate, cost-effective erosion control solution. Ferguson Waterworks was brought on board to address their ongoing concerns.
