When a sinkhole appeared in the middle of a busy suburban road, the City of Swan in Western Australia needed to contract urgent evaluation and repair. Interflow, known for its reputation of quality and cost-effective repair for deteriorated underground pipelines, was able to utilise an alternative approach to repair the problem.

Interflow moved in to complete the work with minimum disruption to the local community and through traffic. As the resulting sinkhole was getting larger it was becoming a danger to pedestrians and vehicular traffic demanding immediate attention.

Creating a solution

During initial investigations, Interflow found that a 900mm drainage pipe under Benara Rd in the suburb of Caversham – a creek crossing running almost at capacity with water and mud – had leaked at joint locations.

The solution was to clean and reline the pipe with a 23m long Rib Loc Expanda liner which has significantly extended the service life of the asset.

Interflow’s Western Australian Operations Manager, Stephen Thomson, said, “It was a pleasure working with the City of Swan Engineering team to find a solution for this unique problem.”

Maintenance making a comeback

Interflow is committed to solving its customers problems and recommend that water infrastructure asset and network owners utilise maintenance programs over CCTV contracts.

The traditional convention of CCTV contracts is limited as they are designed to capture raw footage which is then analysed and graded.

The alternative approach is to integrate this activity into a turn-key scenario whereby a delivery partner, such as Interflow, performs cleaning, CCTV surveys, condition assessment, recommendations and rehabilitation.

Sylvain Cabanel, Interflow’s Business Development Manager WA, said “Using our turn-key solutions and having Interflow carry out assessment and recommendation tasks frees our customers from the heavy workload. Customers only need to review and assess the work that Interflow recommend.”

Preventing potential problems

Interflow employ over 500 employees across Australia and New Zealand and has completed works for all major water authorities and many local and regional councils.

“We work on the prevention side too. Interflow can check stormwater culverts for potential problems and work towards asset management strategies to economically extend the life of underground assets,” Mr Thomson said.
