ESG awarded ground investigation contract to support River Clyde investment

Environmental Scientifics Group (ESG) will deploy its Cheetah Marine catamaran, the MV Pulsar, to undertake a river bed bathymetric survey and debris survey on behalf of Scottish Water.

The company will then use a modular Jack-up Barge to construct boreholes beneath the river bed in order to provide detailed engineering characterisation of the ground conditions and a geo-environmental assessment of foundation soil.

The 12 week land-based and overwater work is part of detailed surveys Scottish Water have embarked on of ground conditions at various locations as part of the planning work for a £250M investment, which is the biggest in the Greater Glasgow area’s waste water network in more than a century.

ESG will also carry out a land-based investigation comprising boreholes up to 45m deep at selected locations, in-situ borehole tests and down-hole geophysical surveys, detailed logging of soil and rock core samples by geologists and routine groundwater and ground gases monitoring. Soil and rock samples will subsequently be selected for geotechnical and contamination testing at ESG’s own laboratories.

The ground investigation results will be used to design project that will improve river water quality and the natural environment of the River Clyde and its tributaries by dealing with sewer flooding and deal with the effects of increased rainfall and climate change.
