Hydro Review: Kashimbila hydropower commissioned in Nigeria

Also, how Long Lake Dam made history in Washington State

State-of-the-art Atlas Polar HYDRORAKE Trash Rake systems keep intakes clean of debris and assure consistent, uninterrupted water flow – even in the most extreme weather conditions.
Scalable and flexible, they sequence to almost any flow or condition on each intake and are customizable to virtually any gauge or bar rack. The trusted #1 debris removal system for over 40 years, HYDRORAKE’s automated 24/7 operation is proven highly efficient, reliable, safer and cost-effective across North America.

If we never adapted to new technology, we’d still be using an abacus to calculate math! Upgrade your turbine sealing face from Carbon to Thordon’s SXL Elastomeric Polymer and:

  • Reduce Seal Leakage
  • Extend Seal Operating Life
  • Install with Ease
