Avoiding hazards

Find out here what you need to do to prevent hazards that can damage our infrastructure.

We have put together these guidelines to help you avoid hazardous situations that can damage our pipelines, during construction works. 

Buildings, obstructions and storage of materials over a main

Placement of structures, equipment, such as cranes, and storage of items over mains can cause excessive loads to be applied resulting in damage or a burst and also prevent or delay access for maintenance, repairs or emergencies.

Our requirements

Storage of materials, placement of equipment, and building of any structure must be no closer than 3m for pipelines smaller than 300mm and 5mm for pipelines bigger than 300mm. Items that can be relocated and do not cause an excessive load are exempt.

Cathodic protection and electrical mitigation systems

Cathodic protection systems reduce pipeline corrosion on metallic pipes by the application of an electrical current. Damage to cathodic protection systems, while having no obvious immediate effect, may cause accelerated deterioration and early failure of a pipeline.

Our requirements

Identify and positively locate any buried cathodic protection components likely to be affected by the work as p art of the site survey.

Chemical discharges and spills

Discharged chemicals including acids and hydrocarbons can damage a main or contaminate water supplies by being absorbed through some pipe wall materials.

Our requirements

Report chemical spills into main drains immediately by calling our 24-hour Faults, Emergencies and Security line on 13 13 75.

Damage to pipelines

Damage to pipelines must be reported immediately by calling our 24-hour Faults, Emergencies and Security line on 13 13 75. Do not a repair or cover up the damage.
