Helping you Manage Dredged Sediments

Dredging and the removal of sediment plays an important role in the positive management of many watercourses.

The sediment itself results from the breakdown of naturally occurring materials such as bedrock, soils and organic matter, which and are transported by water to their resting place. This process has a critical role in shaping our environment and ecosystems.

Unfortunately the accumulation of high levels of sediment and associated suspended solids can sometimes be detrimental to both ecosystems and water quality.

Many locations also require frequent dredging for operational reasons such as managing flood risk or maintaining navigation for boat traffic.

Dredging can be an expensive operation, specialist machinery is often required and the material produced is classified as a waste so it must be managed carefully. Positive management of dredged material can benefit the natural environment and agricultural practice however, without appropriate controls it can be damaging.

Our team at frog environmental is expert in finding practical value engineering solutions tailored to each project. We can manage the environmental risk of projects to protect nature and human health as well as reducing the administrative expense and red tape to ensure a cost effective project.

CEEQUAL assessment

Both founding partners of are CEEQUAL sustainability assessors and led on the environmental management of dredging operations to support the regeneration of the Olympic Park in London. This was a crucial project in the delivery of a vibrant, sustainable and bio-diverse Olympic games and was granted a CEEQUAL ‘excellent’ award for sustainable construction practices.
