Grimsbury Water Treatment Works is a Thames Water facility in Banbury, consisting of a 500m long triangular reservoir and a water treatment plant. MJ Rees has conducted surveys of this site several times over the past 15 years, covering several phases of the site’s development.
Our latest work included producing a wide-ranging topographic survey covering the reservoir, surrounding fields, waterworks and over 1 mile’s worth of the proximate main roads. As it lies within the Cherwell valley and is bounded on one side by the Oxford Canal and on the other by the River Cherwell itself, the site is vulnerable to flooding. As such our comprehensive survey was critical to the next phase of works – allowing the engineers to model the flood behaviour of the local watercourses and to design new connections to the road network. The survey covered several disparate environments, from highways to woodlands, each posing its own technical and health & safety considerations.
