What does sustainable wastewater management mean?

Every property is different. Soil type and depth, slope, available land, waterways, setbacks, climate and the proposed development all influence how wastewater can be safely managed.

A sustainable solution considers these factors together with how the property will actually be used, the client’s priorities and budget, and the ongoing operation and maintenance of the system.

​

This could mean:

• retaining and upgrading an existing wastewater system rather than replacing it unnecessarily

• selecting a treatment system appropriate to the site and proposed development

• safely reusing treated wastewater through irrigation

• designing an effluent disposal area that works with the property’s soil, slope and landscaping

• avoiding unnecessary complexity or over-engineering

• considering future property needs and changing environmental conditions.

 

The most sustainable option isn’t necessarily the biggest, newest or most expensive system. It’s the one that provides a practical, compliant and environmentally responsible solution for that particular property - built for the long term. 

​

Why does it matter?

Good wastewater design protects soils, groundwater, creeks and neighbouring properties while providing a system that owners can realistically operate and maintain.

​

Considering wastewater early in the design process can also identify constraints before plans are locked in, reducing the risk of redesigns, approval delays or unnecessary costs.

Helpful resources

Want to explore sustainable wastewater options further? These NSW Government resources provide useful information on on-site wastewater management, treatment systems, water reuse and sustainable design:​

• NSW Planning Portal: Alternative water sources – information on rainwater, stormwater, greywater and other alternative water sources.

• NSW Planning Portal: Alternative water design principles – practical guidance on reducing potable water use through alternative water sources.

​

The right solution will depend on your site conditions, environmental constraints, proposed development, client needs, budget and long-term maintenance requirements.

The role of a wastewater assessment

A wastewater assessment brings these considerations together.

It looks at the wastewater the development will generate, the characteristics and constraints of the site, council requirements and the treatment and disposal options available.

​

Importantly, it can also identify opportunities to retain existing infrastructure, minimise disturbance, safely reuse treated wastewater and avoid unnecessary costs, while providing capacity for the property’s current and future needs.

By balancing environmental outcomes with good design, practical client needs and cost, wastewater planning can contribute to a more sustainable property overall.
