Thank you for visiting our site! We are excited to share updates about our latest project at the Hobson Lift Station.

In continuous service since 1980, the Hobson Lift Station's electrical components have suffered from corrosion due to hazardous sewer gases. To address this, we are relocating the electrical system away from the wet well to prevent ongoing damage and ensure reliable operations.

Project Highlights:

  • Relocate the electrical system away from the wet well to stop corrosion and reduce downtime.
  • Elevate the electrical pad to protect components from flooding, ensuring long-term reliability.
  • Upgrade to modern standards to improve redundancy and system performance.

These improvements will enhance the Hobson Lift Station's efficiency and reliability, ensuring it continues to serve our community effectively for years to come.

Thank you for your interest in our project. Stay tuned for more updates as we enhance our infrastructure!

    Our team just nailed the drilling of a test hole, setting the stage for the piers that’ll make this project rock-solid. It’s a huge step forward, and we’re pumped!

    Right now, we’re teaming up with the pros at DME to shift a power pole out of the way. It’s all about clearing the path so we can dive into drilling and pouring those piers without a hitch. This collab is keeping things smooth and on track!

    The old wet well has been successfully filled in and secured, marking a significant milestone in the project's progression. The contractor is currently engaged in coordinating efforts to secure a skilled concrete subcontractor to undertake the construction of drilling and pouring piers. Additionally, the power infrastructure has been seamlessly transitioned from the outdated pole to a newly installed one in anticipation of continued electrical upgrades after piers and elevated slab are constructed.

    Construction is underway! We're excited to share that work has commenced on the project. Submittals are currently under review, and on-site activities have begun. As a crucial preparatory step, demolition of the existing wet well has begun, followed by the pumping out of ground water by City crews. This will pave the way for the contractor to proceed with backfilling activities. We're looking forward to the continued progress of this important project.

    Variable frequency drives (VFDs) offer several advantages over traditional switchgear systems in wastewater treatment. Here are the key benefits of VFDs compared to switchgear:

    1. Energy Efficiency: VFDs optimize motor speed based on demand, resulting in energy savings compared to fixed-speed motors controlled by switchgear. By adjusting motor speed to match the required load, VFDs reduce energy consumption and operating costs.
    2. Soft Start and Stop: VFDs allow motors to start and stop gradually, reducing mechanical stress and wear on equipment. This feature prolongs motor life and improves system reliability compared to abrupt starts and stops common with switchgear-controlled motors.
    3. Precise Control: VFDs provide precise control over motor speed, torque, and acceleration. This level of control allows for better process optimization, improved system performance, and the ability to adjust motor operation to meet changing requirements.
    4. Reduced Mechanical Stress: VFDs minimize motor stress and mechanical shock by gradually ramping up motor speed. This results in smoother operation, reduced maintenance needs, and extended equipment lifespan compared to switchgear-controlled motors.
    5. Flexibility: VFDs offer greater flexibility in motor control and operation. They can accommodate varying loads, adjust motor speed to match process requirements, and support multiple operating modes, making them suitable for a wide range of applications and environments.
    6. Improved Power Factor: VFDs can improve power factor by adjusting motor speed and reducing reactive power consumption. This leads to better power quality, reduced line losses, and improved overall electrical system efficiency compared to switchgear-controlled motors.
    7. Diagnostics and Monitoring: VFDs often include built-in diagnostic features and monitoring capabilities. They can provide real-time data on motor performance, energy usage, fault detection, and predictive maintenance, allowing for proactive troubleshooting and optimization of system reliability.

    In summary, VFDs offer significant benefits over switchgear systems, including energy efficiency, soft start and stop capabilities, precise control, reduced mechanical stress, flexibility, improved power factor, and advanced diagnostics. These advantages make VFDs a preferred choice for motor control in modern wastewater treatment applications.
