Water is one of our most precious resources — and in many parts of regional and semi-rural NSW, managing it wisely isn’t just a good idea, it’s a necessity. Drought cycles, population growth and stricter environmental standards mean that homeowners, builders, and developers are being asked to think differently about how water is used, treated, and reused.

 

This is where sustainable water management comes in. By taking a holistic approach to water use on a property, it’s possible to reduce demand, cut costs, and protect local environments.

 

What Is Sustainable Water Management?

At its core, sustainable water management means using water in ways that meet today’s needs without compromising tomorrow’s. In practice, this often involves:

• Minimising mains water demand through rainwater harvesting and efficient fixtures.

• Recycling and reusing water, such as treating greywater for garden irrigation.

• Managing wastewater safely, ensuring effluent is treated and disposed of without harming soil, waterways, or neighbours.

• Designing systems that match local conditions, whether it’s high rainfall around Kangaroo Valley and Batemans Bay or shallow soils in areas like Goulburn and Braidwood.

​

Why It Matters in NSW

In towns and communities across the South Coast, Southern Highlands, and Southern Tablelands — from Kangaroo Valley and Milton to Bowral, Moss Vale, and Goulburn — councils and residents are increasingly conscious of water use and wastewater impacts. Key drivers include:

• Environmental protection – Preventing pollution of creeks, rivers, and groundwater such as the Shoalhaven River and Mulwaree Ponds.

• Water security – Reducing reliance on centralised supply and ensuring resilience during dry periods.

• Compliance and approvals – Councils in places like Shoalhaven, Wingecarribee and Goulburn Mulwaree require developments to demonstrate sustainable water use in their wastewater assessments.

• Cost savings – Efficient systems reduce long-term water bills and maintenance expenses.

 

Practical Options for Property Owners

Sustainable water management can look different depending on the type of property:

• Rainwater harvesting – Common in towns like Moss Vale and Bundanoon, where tanks are used for toilets, laundries or gardens.

• Greywater reuse systems – Popular in drier areas such as Goulburn, Yass and Tarago, where irrigation water is valuable.

• On-site wastewater treatment systems – Septic tanks, aerated systems, evapotranspiration beds or worm farm filtration that recycle water safely.

• Composting toilets – A practical solution for off-grid properties around Kangaloon, Braidwood or Tallong.

• Smart landscaping – Using effluent-friendly plants suited to the local climate, from coastal gardens in Batemans Bay to cool-climate species in Bowral.

 

 

The Role of Wastewater Assessments in Sustainability

A wastewater report (on-site wastewater assessment) isn’t just about ticking a compliance box — it’s an opportunity to design systems that contribute to broader water sustainability. A well-prepared assessment considers:

​

• How much water the property will use.

• What type of system best suits the soil, slope, and climate.

• Opportunities for safe reuse and recycling.

• Long-term management and servicing needs.

 

By planning smartly at the outset, you can integrate wastewater solutions into a sustainable water strategy for the whole property.

 

Looking Ahead

Sustainable water management is quickly becoming a best practice standard. Councils including Shoalhaven (Nowra, Ulladulla, Milton, Berry), Eurobodalla (Batemans Bay, Moruya, Narooma), Wingecarribee (Bowral, Moss Vale, Bundanoon, Hill Top), Goulburn Mulwaree (Goulburn,  Tarago), Yass Valley Council and many others are already embedding sustainability requirements into approvals. Property owners who plan ahead will save time, money, and potential headaches.
