About Us

We were among the first to develop systems for erosion control, lake & pond construction,  and environmental and habitat enhancement, making us experts in aquatic and fluvial engineering. 

A.G.A. Group is the parent organisation under which a number of specialist divisions operate

  • A.G.A. Group Enviro-Fix Limited
  • A.G.A. Civil Engineering Systems
  • A.G.A. Ecology & Land Management Consultants

Our Approach

Being leaders in aquatic & fluvial engineering, the Group’s integrated approach to the management of the aquatic environment takes into account the interaction of the entire systems ecology. No part of an aquatic ecosystem should be viewed in isolation and the holistic approach adopted by A.G.A. Group facilitates a management style that considers all aspects of the environment. An integrated approach can lead to an improved natural balance, the enhancement of biodiversity and an increased productivity of aquatic and terrestrial ecosystems.

Our multi-disciplined team offer complete aquatic engineering services to those responsible for the management of the aquatic environment and wetland systems. A.G.A. Group operates a policy of ‘best practice’ and as such is quality assured to ISO 9001, ISO 14001 and ISO 45001 standards.

The Watford Town Centre Pond has long since been a popular landmark of the Town. In 2020, the Council engaged A.G.A. Group Enviro-Fix Limited to undertake a number of improvements to make the pond more environmentally friendly, and sustainable by introducing more natural ways to keep the water clean and healthy for the plants and wildlife that live there. From the start of the project, A.G.A. acted professionally by firstly offering their expertise in the design of the wetlands and general structure of the pond, and secondly by constructing a team that displayed incredible knowledge of the project. Like most town centre landmarks, the pond is located in an area of heavy footfall, and one of the main challenges faced by the Project Team was undertaking the works whilst ensuring the safety of the general public. A.G.A discussed their proposals with the Council and mobilised the site with adequate signage and all necessary safety features. This was well received by the Project Team and the general public, who were kept informed as the project moved forward. In spite of the project throwing up a number of technical challenges, A.G.A. acted swiftly and professionally to address unforeseen works by minimising the impact on the programme. They also introduced design features that will future-proof the project, and ensure the appearance and water quality remains consistent. The project suffered from the impact of Covid-19, and again A.G.A. acted swiftly to adapt their working procedures and practices to meet government guidelines. They were able to deliver the works during difficult times, and still managed to complete the project in time for the reopening of the Town Centre. As a Project Manager responsible for a variety of projects, I would have no hesitation in recommending A.G.A. to other clients, as their knowledge, professionalism and expertise will add value to any project.

I would like to take this opportunity to thank you and your team for carrying out this project in such a professional and efficient way and I personally can’t wait to get down there to see it in the “flesh” as I understand it looks fantastic.

Blofield Parish Council believes AGA to be efficient, reliable, prompt, courteous and knowledgeable. They are a pleasure to work with. The works undertaken by AGA for the Parish Council was done to a high standard and ahead of schedule. We know now that if we ever need their services again then they will be reliable.

As you are probably aware, there has been extensive flooding in Thetford over the Xmas period.

Thought you might like to know the riverbank you installed for us just over 5 years ago has “more than done the job.”

Despite all three sluice gates opposite to us being fully open, the river went over the opposite river bank 2 days ago and as I write is still doing so. The height of the river bank AGA installed was perfect; at one point, the water pouring into the meadow opposite was at least 6 inches above the river bank on that side. However, the top of our river bank was still 8 inches above the water level. The gardens of houses at either end of the close have flooded – our garden was not affected. We are very grateful to you and your company.

From the Cemeteries Service perspective, we are absolutely thrilled with the finish of the work undertaken by the team. The finishing touches and ‘making good’ of the site have been completed to a very high standard and we are thoroughly pleased.

To see grass seed in the soil that has been laid over tyre tracks and the complete clear up has been very well received by the Cemeteries staff, as well as the visitors to the cemetery.

This time of year is incredibly important for mourners and families that visit the cemetery, to pay their respects at this very family orientated time of year. Our grounds keeping teams are aware of this and always ensure that our grounds are looking their best but to see that your contractors have also taken into account every last detail of making the site look untouched, we are very appreciative.

Our staff noted how friendly and polite the staff were at all times, our contracted grave digger is especially grateful at the small ramp they have installed to his equipment container, after watching him struggle with a mini digger on more than one occasion, he has asked me to pass on his sincere gratitude.

Also the communication with the office staff regarding burials that were taking place in the cemetery, always very polite and helpful. Please pass on our sincere thanks.
