Case Studies

Our team is built according to our client's needs; we draw on a wide range of expertise to build a suitable team, but always maintaining a single point of contact within HalpinRobbins. This point of contact will usually be one of our founders or senior staff:

Royal Borough of Greenwich Lake Restoration

Royal Borough of Greenwich Council commissioned HalpinRobbins to undertake water, silt and ecological investigations at the Tarn, Greenwich, London and to provide a restoration options proposal to restore the Tarn to a beneficial ecological and amenity parkland and lake.

HalpinRobbins undertook a preliminary ecological and environmental assessment of the lake and parkland including surveys for tree bat roosts, aquatic invertebrates, lake bathymetry, lake sediment and water quality and parkland soil quality.

The lake was found to have less than 35% of its original water capacity with the remainder filled with sediment containing high levels of metal and oil contamination due to significant urban drainage feeding into the site. This contamination was found to have reduced the number of aquatic invertebrates within the lake and cause several other ecological and environmental issues.

As well as constant liaison with the client further discussion were undertaken, and maintained, with local community groups, Transport for London, Thames Water and Environment Agency throughout the project to develop a greater understanding of the history of the Tarn, its use within the community and surrounding area and to understand the water source of the Tarn lake.

HalpinRobbins produced a treatment and remediation plan with costings to enable Royal Borough of Greenwich Council to undertake in-house budget assessments and develop an ongoing strategy to remediate and restore the lake and park land.

The project is ongoing.
