VLT® AQUA Drive FC 202

Canneberges Drummond Inc. recently completed a major modernization of their pumping system, transitioning from diesel to an eco-friendly, automated solution—thanks to the collaboration of Kopers and 6MGB. By integrating Danfoss VLT® AQUA Drive FC 202, MCT 31 Harmonic Calculation Software, and the VLT® Advanced Harmonic Filter, the cranberry producer achieved: reduced CO2 emissions, improved system reliability, lower operational costs. 

In early 2023, the Warren County Utility District (WCUD) in middle Tennessee was faced with a dilemma. The water tank in their Short Mountain (SM) pressure zone required cleaning and repairs as part of federal compliance regulations, but with only one tank in the pressure zone, as is the case with many rural municipalities, they had few options to maintain water service to customers while the tank was out of service during the washout process and while repairs were completed. WCUD maintains a 4.0 MGD Water Treatment Plant, six storage tanks, four remote pump stations, into four pressure zones with approximately 650 miles of mains to serve 9,000 customers in rural portions of Warren and five adjacent counties.

The Grand Strand Water and Sewer Authority in Myrtle Beach, South Carolina was struggling to keep up with demand at one of its main sewage pressure reducing stations. Myrtle Beach, a popular tourist destination, uses approximately 15 million gallons of water per day (MGD) or 5.5 billion gallons of water per year. The South Regional Pressure Reducing Station handles approximately 3 MGD and is controlled by suction pressure and a PID (proportional-integral-derivative) loop.  Its purpose is to reduce pressure on the south side of the sewer district to enable the other stations to pump more.

Across the United States, cities are facing the challenge of an aging infrastructure. Atlanta experienced this firsthand in 2020, when a cabinet that housed critical electrical equipment at one of its larger pumping stations burned up following a lightning storm. The City had already made major repairs to the station after a flood six months earlier. The electrical accident and the fact that the aged electrical distribution was original to the building led the City to declare the station unsafe. It was clear the nearly 50-year-old station would need to be rebuilt, but with the work not scheduled to begin for several years, a solution needed to be found that would enable the station to maintain its critical function.

Water presents a significant risk to mining operations, potentially causing equipment damage and environmental contamination. A robust pumping system is required to control the flow of water and remove it from the work site. A large copper mine in Arizona had reached a critical stage where they needed to replace their 250-horsepower (HP) dewatering pump and increase pumping capacity.
