Sedimental Value

The Estuary is close to two of London’s largest wastewater treatment facilities, as well as being the point of highest suspended particulate matter along the tidal Thames.

New life would be injected into the banks of the Estuary through water management, sediment capture, and soil remediation. 

Soil remediation would create suitable conditions for food production.

Sedimental Value

Restore the damaged riverbanks of the Thames Estuary

The Thames Estuary is one of the most biologically sensitive ecozones in the UK, but the health of its riparian communities have been significantly damaged by years of heavy industry, channelisation and erosion. These issues are exacerbated by heavy flooding and sedimentation, both of which are expected to increase over time as a result of global warming and rising sea levels.

Sedimental Value aims to ameliorate the ecological damage inflicted upon the Thames with green infrastructure technologies, while simultaneously addressing the issues of flooding and land reclamation.

In addition to new riverside parkland, which can absorb excess floodwater within its intertidal marshes, 12 large infrastructural piers would be inserted into the river.

The curved piers would be designed to increase river turbidity and concentrate fluvial sediment into collection receptacles on the opposite bank. This sediment would then be collected and cleansed in hanging dewatering bags impregnated with bio- and phyto-remediative organisms
