Development of the urban fringe surrounding major population centres can be held up or prevented due to existing municipal sewerage infrastructure being too far away or at capacity.

Generally, development throughout Australia has placed pressure on traditional sewerage servicing methods with state and federal governments and utilities agreeing a change in approach is needed to meet regional demand.

The current centralised model requires sewage to be conveyed via extensive pipe networks to a single point for treatment and environmental discharge.

Large networks incur high operation and maintenance expenses. These municipal networks are central to service provision but limited when faced with lower population density or distance.

Sustainable sanitation options must combine reliable technology with economic feasibility. One solution is decentralisation which involves the collection, treatment and potential reuse of wastewater from homes and buildings within a single development or community.

Decentralisation of wastewater services

From an economic point of view, the most important advantage of decentralisation is reduced investment costs for the network.

If wastewater treatment facilities are located at the source (housing areas), the construction of an extended sewage conveyance network is no longer necessary.

Instead, sewage is treated in smaller volumes and reused for applications nearby at lower cost.

Given the growing problem of water shortages, particularly for drought effected communities, the more efficient use and reuse of water is a key benefit.

True Water Australia offers innovative sewage management, treatment and reuse solutions for community and urban applications.

Through its partnership with global leaders Kubota, True Water has developed an infrastructure model to specifically meet the servicing challenges of regional towns, satellite communities and the urban fringe.

In addition, each decentralised system can be tailor-made to suit local climatic conditions, aesthetic requirements, water quality objectives and end uses.

This model was applied in the Greater Flagstone Priority Development Area, south-west of Brisbane. The area has potential to meet the housing needs for the region, but the lack of access to traditional municipal sewerage services as a stumbling block.

True Water designed a decentralised solution utilising Kubota’s sewage treatment technology. It provides the best economic outcome, secures operational compliance and satisfies environmental regulations, allowing the development of otherwise unserviceable sites.

Collaboration on sewerage infrastructure

The successful collaboration between True Water Australia and Kubota results in the installation of state-of-the-art biological sewerage infrastructure across Australia and the Pacific.

The Kubota sewage treatment plants are easy to manage and cost effective, using refined but uncomplicated technology to achieve the highest level of treatment and safety.

Compared to other treatment options, this Japanese technology delivers a highly robust treatment process and low operating costs.

The modular systems satisfy rigorous quality benchmarks and manufacturing standards guaranteeing quality, performance and longevity.

True Water chooses to utilise Kubota’s state-of-the-art treatment technology to deliver fit-for-purpose, high-quality solutions for every project they are involved in.

Decentralised systems offer great potential to reduce capital investment and ongoing costs for sewerage networks.

Consequently, this alternative approach to integrated wastewater management offers a promising alternative to conventional centralised systems, not only to municipalities but also to the private sector.
