Sewerage

Related Topics and Links

The Sewerage network is generally taken to be comprised on the sewage collection network (sewerage pipes leading from private, commercial and public premises), sewage pumping stations and inspection points and sewage treatment and reuse or disposal processes. Sewage treatment is also known as wastewater treatment. 

Environmentally Relevant Activity 63 (ERA 63) in the Environmental Protection Regulations (EP Regs 2008) includes the operation of Sewage Treatment and also large sewage pumping stations in order to regulate potential environmental harm from discharges, reuse or overflows. Overflows from the sewerage network and pumping stations may occur in wet weather when sewage flows are increased from illegal connections to the network and because of stormwater infiltration. Sewerage systems are designed to overflow at selected points when necessary to prevent back-up of sewage and reduce the potential for spills within private premises.


Based on DERM guidelines and industry contributions qldwater distributed Sewage Overflow Guidelines and a template in 2010 for Service Providers to create individual Sewer Overflow Policies. These guidelines included a template for a Sewerage Incident Emergency Response Manual.
