Current Members of the Committee

Member - GEOFF SWEANEY 


Geoff is a director of Wetland Engineering, a company dedicated to the design of "soft" engineering of landscapes to deliver benefits to water quality, flood risk and wildlife habitat.  His first job in1993 was management of a 7 hectare treatment wetland for indstrial wastewater from ICI Billingham.  Over the years he has worked on a wide variety of constructed wetland projects, including wetlands for Natural Flood Management, Sustainable Drainage, and treatment of industrial effluents, mine water and contaminated groundwater.  He is also active in the river restoration sector and is a director of the Calder Rivers Trust.  Geoff joined the CWA in 2008 and was elected to the committee in 2014 as Chairman.

Treasurer – ANDY FREEMAN

Andy is currently working as a project Scientist for ARM Group Ltd, a company that supplies design construction and maintenance services for constructed wetlands for wastewater treatment. Having developed a passion for the science underpinning wastewater treatment using constructed wetlands, Andy’s specific area of expertise is the monitoring, characterisation and treatment of de-icer contaminated stormwater run-off from airports, which was the topic of his PhD that he successfully defended in 2016. Andy has presented research in the UK and Internationally and published peer reviewed journals within Science of the Total Environment, Environmental Technology and Innovation and Water Science and Technology.  Andy joined the CWA committee inn2018 and was elected treasurer in 2019.

Member – CAT McILWRAITH

Cat is a GIS analyst for the Rivers Trust. The Rivers Trust is the umbrella organisation for 60 local member Trusts. It is the only group of environmental charities in the UK and Ireland dedicated to protecting and improving river environments for the benefit of people and wildlife.

Cat served on the committee between 2014-2017 and was re-elected in 2019.

Member – MATTHEW SIMPSON

Matthew is a Director of 35percent, a consultancy dedicated to all aspects of wetland design and management, and has extensive experience in water, wetland and biodiversity assessment and management. Matthew is responsible for developing, managing and reporting on a range of projects and providing specialist eco-hydrological, wetland restoration, creation and wetland management advice. His PhD focused on developing a practical classification and functional evaluation tool for European wetland ecosystems. Matthew has been on the committee since 2011. 

Member – GABRIELA DOTRO

Gabriela Dotro is a Senior Research Fellow with Cranfield University and a passionate wetland advocate, Gaby’s main area of expertise is nature-based solutions for wastewater treatment and biogeochemical transformation of phosphorus, iron and nitrate in natural and engineered systems. She is currently working on the development and improvement of nature-based solutions to deliver multiple benefits beyond wastewater treatment. She has recently co-authored an Open Access textbook on Treatment Wetlands, edited and co-authored specific chapters within the upcoming IWA Scientific and Technical Report on Wetland Technology, and is developing a suite of online CPD courses on ecological engineering.  Gaby was elected as a member of the CWA Committee in 2012.

Member – DAVID NAISMITH

Dave works for the Wildfowl and Wetlands Trust. He has worked as a technical designer and project manager on a range of habitat creation, SuDS, NFM and treatment wetland projects. Recently he has been working on nutrient neutrality wetlands focusing on Nitrogen and Phosphorus, and designing water quality improvement wetlands to buffer down-stream protected sites such as Ramsar, SSSI and NNR nature reserves. He has also worked on urban and community based wetland projects such as daylighting streams, SuDS in schools and urban green/blue space landscape design. In 2020 he was one of the judges for the Landscape Institute Awards for the Excellence in Flood and Water category and will be presenting at the LI Greener Recovery Festival on the Sustainable Water Management in March 2021, both have been great opportunites to promote wetlands within the profession further.


Dave is passionate about wetlands and will continue to work towards furthering knowledge, understanding and technological application of treatment solutions to as wider an audience as possible. He sees the work of the CWA as critical in bringing together a wide ranging and highly skilled group of people to promote knowledge sharing and to raise the profile and understanding of wetlands in the UK. 

David joined the committee in 2019.

 

Member – JOHN WILLIAMS

John is Professor of Environmental Technology in the School of Civil Engineering and Surveying at the University of Portsmouth.  He arrived in Portsmouth in 1988 to undertake a PhD on nitrogen cycling and pathogen removal in field scale Gravel Bed Hydroponic constructed wetlands in the UK and Egypt.  He has since worked on a range of constructed wetland projects in the UK and overseas.  In recent years his work has focused on pollutant removal in vegetated Sustainable Drainage systems. John is the academic lead for the University's Environmental Technology Field Station based at an operational sewage works which hosts an Innovation Hub for wastewater technologies in collaboration with Southern Water. John was elected to the CWA Committee in 2019.

Member - LUCY CROCKFORD

Lucy is a Senior Lecturer in Soil and Water Management at Harper Adams University with a wide range of research interests ranging across environmental chemistry, physics and engineering. Her primary degree was in Environmental Science at NUI, Galway (2006), with an MSc in Environmental Engineering at Queen's University Belfast (2010), a couple of years after some experience in industry. Her PhD research in Geography at the University of Dublin, Trinity College (2015), determined the application of high temporal resolution data in the management of eutrophic water bodies in agricultural catchments.

Lucy's research at Harper Adams University is primarily in the application of organic amendments to soils and the impact on soil structure and water movement dynamics - as well as the resulting water quality. The role of constructed wetlands and more natural methods of water treatment are a developing area at the university. She is also very interested in catchments with high sediment movement and looking to expand her knowledge in this area particularly into Africa and small holding farming.
