Location: Hampshire, UK

Project Value: £2.64m

To help serve the growing commercial and residential developments in the Fleet area, Ward & Burke were engaged to design and construct a 25m diameter underground storage water tank, which upon completion, would assist in flood relief during storm conditions.


Works involved:

  • Design, fabrication and installation of cofferdam 32m diameter 22m deep, and reinforced storage shaft 25m diameter x 18m deep within cofferdam
  • Installation of temporary dewatering system by specialist company to help reduce artesian pressures in the underground aquifers
  • Construction of Internal 7m shaft within
  • Construction of precast roof slabs manufactured at our offsite facility
  • Full hydrostatic test on structure

The design allowed for the shaft walls to be constructed above existing ground level, and through precise design and constructability, for it to be sunk to finished formation level.

This project won the Institution of Civil Engineers 2016 Excellence in Construction Award at the South East England Excellence in Construction Awards.
