Established in 1989, OGI Groundwater Specialists Ltd is an
independent, privately owned British company specialising in
designing Groundwater Control systems to dewater and strengthen
OGI provides professional services to the Waste Water Industry
to reduce the cost of temporary works during the construction of
subsurface structures and pipelines.
Working with the project structural engineers, OGI also develops
systems to reduce the earth pressures on underground structures
which can result in a significant reduction in construction
programme and out-turn costs.
Groundwater Control and Geotechnical Design at previous UK Waste
Designing efficient dewatering systems to minimise installation,
hire and fuel costs.
Stabilising retaining embankments as an alternative to retaining
Design of king post walls as an alternative to secant or
contiguous pile walls.
Design of passive pore pressure relief systems to reduce
artesian uplift pressure and so reduce costs of additional
excavation and reduce mass of concrete gravity structure.
Combining technologies to provide innovative solutions to reduce
Delivering procedures that reduce Carbon Dioxide emissions.
Temporary works designs that are integrated with the permanent
works designs to ensure safe construction, including sufficient
space surrounding the structure.
OGIís designs are developed from over 25 years of experience in
delivering Groundwater Control solutions to contractors,
consultants and project clients.
Our designs are presented as clear practical drawings supported
by comprehensive design certificates. Groundwater Control and
Geotechnical designs follow Eurocode EC7, which provides a
standard framework for OGIís safe, innovative and cost effective
We also present regular Groundwater Control seminars to industry
suitable for project managers, engineers and anyone who is
interested in learning how to recognise, understand and apply
various techniques to overcome groundwater problems and to
mitigate project damage, delay or accidents. See our
