Thames Valley Reservoir Refurbishment

The Thames Valley reservoir refurbishment programme consisted of 5 No. pre-load reservoirs at various rural locations. The reservoirs were constructed during the 1950s. Pre-stressed concrete tanks were constructed as they provided a quick and cost effective means of constructing a water tight vessel (in this case potable water). Due to the collapse of a similar reservoir in Lanner Hill, Cornwell in 1999 and Thames Water’s requirement to maintain a 10 yearly inspection programme, Barhale was commissioned to inspect and report on the condition of the reservoirs. Barhale engaged the assistance of a specialised structural engineer. From the inspections and reports, recommendations were provided for the repair / refurbishment. This was then undertaken by the project team.
