Regular Tank Cleaning Protects Water Quality and Prolongs Asset Life
Reservoirs and tanks are central to water quality and supply reliability. Sediment, sludge and biofilm accumulate over time, reducing storage capacity and, in potable systems, posing a risk to water quality. Veolia's reservoir and tank cleaning services remove accumulated material and restore assets to a clean, well-maintained condition across both potable and wastewater systems. From individual reservoirs and tanks to entire process plants, we deliver cleaning that protects water quality, capacity and asset life.
What is Reservoir and Water Tank Cleaning?
Reservoir and water tank cleaning is the removal of accumulated sediment, sludge and deposits from water storage and treatment assets. In potable systems this protects water quality by removing material that can harbour contaminants and affect taste, colour and safety. In wastewater systems it restores capacity and maintains treatment performance.
Desludging is a core part of this work, recovering settled solids from the base of reservoirs, tanks and lagoons. For treatment sites, cleaning can extend across the entire process flow, returning the full asset to a clean, reliable operating condition.

Why do reservoirs and tanks need cleaning?
Sediment, sludge and biofilm accumulate over time, reducing storage capacity and, in potable systems, posing a risk to water quality. Regular cleaning and desludging restore capacity and protect water quality.
Do you clean potable (drinking) water assets?
Yes. We provide potable water process flow cleaning across entire potable water process plants, as well as reservoir and tank cleaning, applying the appropriate standards to protect water quality.
Can you clean an entire treatment plant, not just one tank?
Yes. Our process flow cleaning services cover entire potable and wastewater process plant assets, so we can clean the full process train rather than isolated units.
What is reservoir desludging?
Desludging removes settled solids and sediment from the base of a reservoir, tank or lagoon, restoring storage capacity and helping maintain water quality and treatment performance.
Will cleaning disrupt operations?
We coordinate cleaning and desludging with your operations to minimise disruption, and can plan works around supply requirements and asset availability.
