Binnies has been appointed by Portsmouth Water to provide the reservoir Construction Engineer, appointed under the Reservoirs Act 1975, and geotechnical specialist for the Havant Thicket Reservoir (HTR) project.
The project is the first major water storage reservoir to be designed and constructed in England for 30 years. The project is currently in the early stages of detailed design, site investigation and site preparation, including a trial embankment and compaction trials.
Binnies geotechnical specialist, Mark Wheeler, will review the design and construction of the embankment. He is a technical director with over 40 years’ engineering geology and geotechnical experience, mainly on heavy civil engineering works.
The reservoir is an environmentally led project that will help to protect two internationally rare chalk rivers in Hampshire by providing an alternative, sustainable source of water. It will supply water to about 160,000 people during an average year. The reservoir is due to be completed and operational by 2029. It includes a major embankment, which will be up to 20 metres high, with a three-kilometre-long zoned embankment dam with concrete outlet culvert and valve tower.
