OGI was established in 1989 as a consultancy specialising in the field of groundwater, mainly solving problems within the construction industry and providing ground energy resource calculations to the building industry.

During the nineties the company expanded to include specialist construction dewatering services to UK contractors.  This included building up a fleet of dewatering pumps and developing safe and secure dewatering techniques for use in major construction projects.

Between 2004 and 2010, OGI formed a number of partnerships within the UK and Europe to provide a comprehensive design and contracting service for the installation of ground source heating and cooling systems.  Projects soon built up to the size of hospitals, schools and health centres.

From purpose built offices in County Durham, OGI provides a range of groundwater related services to industry including the design and installation of Construction Dewatering and Ground Source Heating and Cooling Systems.  All designs are bespoke and tailored to site specific details.

OGI is almost unique in the UK as we bridge the gap between contractor and consultant offering a full service package from design through to maintenance. We remain a knowledge based organisation and our contracting services are supported by a carefully selected group of key approved suppliers/sub-contractors to deliver our clients a one point of contact service to most regions of the UK.
