B&NES Council has undertaken a programme of works to ensure the long-term security of supply from the historic Bath Hot Springs. Zenith Global was commissioned to provide technical expertise on the drilling of a new inclined borehole and backfilling of an old, vertical borehole. The new borehole is for a supply of thermal water to a new five star hotel in the city of Bath.
Project
Zenith Global provided technical advice during the drilling of the new inclined borehole and designed and project managed the backfilling of the old artesian borehole drilled into one of the natural springs. The backfilling works provided many unforeseen challenges: the borehole construction was different from that recorded; and materials were compromised by corrosion, requiring innovative solutions and effective negotiations between interested parties. The outcome was a much reduced spring flow, back to levels observed prior to the borehole construction. Additionally, Zenith Global successfully negotiated with the Environment Agency the update of the Bath Hot Springs abstraction licence.
The result was a newly licensed borehole ready for use and more flexibility within the licence to enable effective source management, whilst maintaining security of supply for the future.
