Environmental Engineering

ART specialise in delivering tailor made solutions using engineered approaches. 

We offer advice, project management and construction services to developers, landowners and agriculture.

Recent environmental engineering projects

Fish Passes


ART have been instrumental in delivering a variety of barrier easements across various catchments, overcoming a host of problems for migratory fish. Here are a few examples: following examples:

  • Technical Lariner fish pass construction at Sevenacres Weir on the Lugton Water, near Kilwinning – value circa £400k
  • Timber baffle fish pass installation on the Tulloch Water at Tulloch bridge on the Irvine catchment – value circa £12k
  • Design and installation of oak and plastic baffle fish passes at two culverts on the Bogend Burn at Catrine on the River Ayr – value circa £6k

These installations are designed to improve fish passage over obstacles and reconnect fish with habitat from which they have been excluded. ART biologists monitor fish population recovery following the installations.


Green Engineering


In recent years, green engineering techniques have become increasingly important for river restoration and are often preferred over more traditional, hard engineering solutions. ART staff are experienced in numerous techniques using natural materials and sustainable alternatives. Using green approaches to stabilise or restore degraded riverbanks offers many benefits for water quality, instream habitat and biodiversity. 

Recent projects include the repair and construction of the River Ayr Way following a bank collapse in conjunction with East Ayrshire Council at Nether Wellwood.



Further upstream on the River Ayr catchment we worked with two landowners to halt bank erosion that was contributing large volumes of silt and sand to the watercourse. By protecting the banks with a range of techniques we were able to reduce the amount of land lost to the river. This was a major benefit to the landowner as well as to the river environment and spawning fish.
