Maintain the Performance of Your Water Networks With Regular Dewatering & Desludging
Over time, sludge, silt and solids accumulate in lagoons, tanks, inlet structures and channels, reducing capacity, treatment performance and asset life. Veolia's dewatering and desludging services remove and manage these solids, restoring capacity and keeping your assets performing, while handling the recovered material responsibly.
Combining tankering, dewatering and a broad range of corrective maintenance activities, we deliver the full scope of works needed to keep networks and treatment assets in service.
What is Dewatering and Desludging?
Desludging is the removal of accumulated sludge and solids from lagoons, tanks, inlet structures and channels. As solids build up, they take up volume that should be available for storage or treatment, so periodic removal is essential to maintain capacity and performance.
Dewatering separates water from the recovered sludge and waste, reducing the volume and weight of material that has to be transported and disposed of. Together, desludging and dewatering restore asset capacity while making the handling and disposal of recovered material more efficient and cost-effective.

Why does sludge need to be removed?
Accumulated sludge takes up volume that should be available for storage or treatment, reducing capacity and performance and shortening asset life. Periodic desludging restores that capacity.
What is the benefit of dewatering the recovered sludge?
Dewatering separates water from the solids, reducing the volume and weight of material to be transported and disposed of, which lowers handling and disposal costs.
Can you respond to environmental spills and overflows?
Yes. We provide responsive overflow cleaning, including environmental overland and in-water spill cleaning, to help protect waterways and meet environmental obligations.
Do you handle disposal of the recovered waste?
Yes. Our scope includes tankering and contaminated waste disposal, drawing on Veolia's broader resource and waste management capability to manage material to the appropriate standards.
