Maintenance and cleaning of water, sewage & wastewater infrastructure

Maintenance programs for water and wastewater networks are crucial to maintain and improve asset performance and protect public health & the environment. Veolia can assist customers to identify water network issues through complete asset management and condition assessment reports allowing customers to implement the most appropriate maintenance and rehabilitation strategies.

Using our large range of specialist equipment including modern water recycler combination units and a highly skilled team, we can perform effective maintenance and cleaning of all types of pipeline networks, including sewage systems, sewage treatment plants, potable water, stormwater and industrial pipework systems. We can also remove and dispose of silt, grit, sludge and other undesirable waste from wet wells, digesters, pits and tanks, without the need for confined space entry.

We can easily adapt to urban network situations as well as operating constraints in industrial complexes.


Veolia Water Technologies was awarded the contract by Queensland Urban Utilities for the provision of sewer cleaning, CCTV survey, condition assessment and evaluation services of the sewers network including pump stations and wet wells. The contract also delivers specific sewer maintenance services both for planned programs and for response to faults and emergencies for gravity sewers, associated infrastructure and rising mains. QUU’s main objective is to maintain a high level of uninterrupted reticulation and trunk sewer service while optimising the sewer maintenance life of all system assets.
