Brennan's fleet of hydraulic dredges has been highly customized for accurate positioning and precise removal of sediments in a variety of face thicknesses and material types. Our methodical capability of running production remedial dredging simultaneously to residual removal drives increased efficiencies, while proprietary modifications and patented tools ensure successful results.
Hydraulic dredging is one of the most efficient forms of removal and transport, and because all material
is contained within a sealed pipeline, there is minimal impact to the surrounding community and infrastructure. When combined with a proper debris management program, hydraulic dredging is one of the most economical and effective approaches for challenging dredge conditions.
When considering a hydraulic dredging option, one should not assume that the presence of heavy debris will be an impediment to production. Coupled with an aggressive debris management program, hydraulic dredging can be every bit as effective as a mechanical dredge plan. At Brennan, we often implement a hybrid dredge plan that incorporates both surgical hydraulic dredging and precise mechanical dredging. This approach will maximize production while ensuring that any dredge residuals are minimized/ eliminated.
In addition to our dredging capabilities, a complete remediation and restoration often involves the installation of a barrier wall system and turbidty controls. When dredging is completed, the river bottom or lakebed is often covered with sand or an engineered cap to create a clean substrate for re-population of the benthic community.
J.F. Brennan Company specializes in water-based remediation and habitat restoration projects throughout the United States. We have successfully completed some of the most challenging environmental dredging and restoration projects to date.
