VESI Environmental Ltd specialises in water and land ecosystem
management services. The company has been at the forefront of
innovative ‘green and blue’ infrastructural technology -
delivering innovative sustainable solutions that are socially,
economically and environmentally coherent. VESI and its staff
have been pioneers in the development and application of the
'Integrated Constructed Wetland' (ICW) concept for municipal,
agricultural and industrial wastewaters, mine drainage and
VESI’s staff have been lead authors involved the preparation of
Government Guidelines for ICW use in Ireland and Scotland.
VESI’s special focus on the use of ICW systems is because of the
many ecosystem services and functional benefits that they
provide for both humans and nature. These include amongst
others, their cost effectiveness in the qualitative and
quantitative management of water, habitat and biodiversity
management, provision of recreation/education facilities and
associated enhanced landscape aesthetics.
The ICW concept and its application are supported by more than
70 scientific peer-reviewed journal papers and more than 100
demonstrations where Vesi and its associates have been key
contributors. Their work has attracted wide international
interest including that from: USA, PR China, New Zealand,
Finland, Sweden, Italy, UK, Belgium and France.
VESI Environmental Ltd has undertaken trials on the use of
Integrated Constructed Wetlands on the treatment of various
wastewater types. The methodologies used in our trial studies
have been further developed demonstrating the strong scientific
basis of VESI’s approach to less understood areas of water
management especially that of managing emerging contaminants.
These and new studies factually demonstrate the widest range of
ecosystem benefits accruing from this integrated approach to
land and water management, including the capture and retrieval
of sequestered phosphorous, nitrogen, heavy metals and carbon,
thus explicitly providing multiple functional benefits, rather
than just the sole dimension of addressing water quality alone.
