SUSTECH - Key Persons


Eoghan O'Flaherty

Job Titles:
  • Director
Eoghan has been a part of Sustech since 2008. With a passionate interest in the science of the interfaces between humans and our natural water resources, he completed his undergraduate degree in Trinity College Dublin in 2009, B.A. (Mod.) Environmental Science, with a final year project on the assessment of biological foaming in activated sludge. This led to postgraduate work on wastewater characterisation and assessment using respirometry in the TCD Centre for the Environment. He was also awarded a Postgraduate Diploma in Statistics from TCD in 2012. Over the past 14 years, Eoghan has developed a depth of experience in a wide variety of fields pertaining to environmental services. As a published author with specialist knowledge in activated sludge wastewater treatment systems, he has helped industrial clients design, upgrade, optimise and troubleshoot performance in their wastewater treatment plants across Ireland and further afield. Complementing his work with wastewater treatment plants, he also has substantial experience in identifying and assessing appropriate discharge pathways for effluent post-treatment. He has considerable experience in managing effluent discharge projects which can typically include assimilative capacity assessments, surface water and groundwater assessments, site risk evaluations, discharge licensing and regulation. Given the abundance of environmental legislation and regulation in Ireland and the EU, Eoghan also has experience in the design and implementation of environmental strategies for our clients which ensure that they continue to comply with existing or pending legislation and regulation (e.g. EU BAT BREF impact assessment). By the very nature of our client base, he has a comprehensive understanding of the entire Industrial Emissions Directive licensing process (formerly IPPC licences) from initial application to licence review and finally licence surrender. He has experience in auditing and implementation of ISO 14001 and EMAS standards in industrial sites, particularly with regard to effluent treatment and aqueous wastes. Eoghan has a keen interest in using data analytics and modelling techniques to enable our clients to make informed, economically feasible and environmentally sound decisions in the data-rich field of environmental science.
