Development in upland environments invariably affects local water movement, and peatlands. Measures to reduce the development impact in these challenging environments must be well founded, practical and cost effective.

WHS has been working in renewable energy since 2004. We provide environmental impact assessments and flood services for wind farms, solar farms and hydropower schemes, and resource assessments for hydropower schemes.

We specialise in devising robust and effective strategies to reduce impact, based on sound risk assessments.

Our river flow assessment tools lead the industry. The WHS engineers and scientists behind LowFlows and Flood Estimation Handbook (FEH) software have nationally recognised expertise, and are highly regarded by regulators.

Our scale is our strength. We work closely with you, keeping the focus on precise requirements, whether in demanding field sites, or analysis and liaison with stakeholders.

  • clients from major energy utilities to private individuals
  • projects from 150MW wind farms and 2.5MW hydropower schemes to small community-based projects
  • providing expert witness evidence at public inquiry.

The last word from our clients

“This has been a hugely demanding and challenging project and I would like to thank you for your efforts in getting this project over the line, it really would not have been possible without you. I’m extremely grateful.”
