Investigating extending the sewerage network

South East Water has been working with the City of Casey, under their Domestic Wastewater Management Plan, to identify areas where household waste from failing septic systems is polluting groundwater and the environment. Harkaway has been identified as an area where this is occurring.

To remove this risk for the community, we're investigating extending the sewerage network to the township of Harkaway, to reduce the use of existing onsite septic tanks on smaller blocks (under 0.4 hectares).  

What we're doing

We're looking at installing a pressure sewer system in Harkaway, rather than a traditional gravity sewer system. A pressure sewer system requires smaller sewer pipes to be inistalled, which can normally be done via horizontal directional drilling, minimising construction impacts on the community and the environment.  

Wastewater from households is collected in a pump and tank unit (installed on the property and connected into the sewer network) prior to being pumped into the sewer mains in the street and taken away under pressure to the water recycling plant for treatment.  

We're currently undertaking early stage surveying works.

Don't miss these details

Once we've completed our investigations, we'll provide an update on the project.

Using a pressure sewer system will allow households using tank water to access the sewerage network, as at this time, South East Water has no plans to extend potable water services to Harkaway.
