Inside Our Sustainable Communities: What 500+ Altogether Neighbourhoods Are Teaching Us

Altogether now supports more than 500 sustainable communities across Australia, from high‑rise precincts to regional towns and lifestyle villages. Across that portfolio, one message is clear: when energy, water and data are planned together as embedded utilities, communities become more resilient, affordable and enjoyable places to live.

In this article, we look inside those neighbourhoods to share what’s working best for sustainable communities today, and how those insights are shaping the next generation of precincts.

What we’re learning from 500+ sustainable communities

No two Altogether communities look the same, but the ones that perform best share some consistent patterns. Developments that treat utilities as an integrated system, rather than a checklist of separate services, are proving more efficient and future‑ready.

Embedded energy networks, recycled water schemes and smart metering create a connected backbone that supports both environmental outcomes and day‑to‑day liveability. From the Hunter Valley’s first new town in 50 years to over‑50s lifestyle villages and urban build‑to‑rent precincts, these communities are setting a benchmark for sustainable living at scale.

Across Altogether’s communities, high‑performing sustainable neighbourhoods tend to:

• Plan energy, water and data together from day one in the masterplan.

• Use embedded utilities (local energy and water networks) to keep resources circulating on site.

• Rely on smart meters and data to improve performance over time.

Energy: Embedded networks powering everyday life

One of the strongest signals from Altogether’s portfolio is the impact of embedded energy networks on both emissions and affordability. Instead of every home or apartment sourcing power individually from the main grid, an embedded network buys or generates electricity in bulk and distributes it within the community through a private network.

In practice, this makes it easier to integrate rooftop solar, battery storage and, increasingly, EV charging into the fabric of a precinct. For residents, it usually looks like lower, more predictable bills and simple, digital access to usage information, rather than needing to think about the complexity behind the scenes.

At Seachange Toowoomba, for example, Altogether owns, operates and maintains an advanced embedded energy network and solar system that automatically adjusts how energy is shared across the village. Residents benefit from localised clean energy that can be distributed at no cost for communal uses, helping to keep living costs down while supporting a low‑carbon lifestyle.​

From 500+ communities, key energy lessons include:

• Embedded energy networks are a practical way to integrate solar, batteries and EV charging at scale.

• Bulk purchasing and smart controls can help deliver real bill savings for residents.

• Data from smart meters is essential for optimising performance over time.

Water: Closing the loop in water‑wise neighbourhoods

If energy is about decarbonisation, water is where sustainable communities really demonstrate circular thinking. Our regional and urban schemes increasingly use dual‑reticulated networks, with one system for drinking water and another for high‑quality recycled water processed in local treatment plants.

Huntlee in the Hunter Valley is a good example of what this looks like in practice. Here, an advanced recycled water treatment plant supplies water for toilet flushing, garden irrigation, dust suppression, street cleaning and laundry, helping residents avoid the harsh outdoor restrictions that can come with drought. In some regional towns Altogether supports, decentralised systems have achieved up to 70% water reuse and enabled “zero wastewater discharge” into local waterways.

Across more than 500 communities, localised water infrastructure has now recycled over 1.2 billion litres of water, easing pressure on potable supplies while supporting green, shaded public spaces. Builder guides, pipe colour‑coding and customer education keep recycled water safe and simple to use, even as the systems behind it become more sophisticated.

Transport and EV readiness: Utilities behind mobility

Transport is changing fast, and Altogether’s embedded utilities are increasingly part of that story. As EV ownership grows, many new communities expect convenient charging without compromising building performance or overloading the grid.

Embedded energy networks make it simpler to design EV‑ready buildings, with capacity for common‑area chargers and apartment‑level solutions built into the electrical backbone from the start. By pairing on‑site solar with battery storage, these systems can supply a portion of EV demand locally and smooth out peaks, which benefits both residents and networks.

What Altogether’s communities are showing about EV‑ready sustainable communities:

• Planning EV capacity early is more cost‑effective than retrofitting later.

• Shared, solar‑powered charging is a strong fit with embedded networks.

• Residents value seamless charging that “just works” with their existing utilities.

Community connection: How shared utilities bring neighbours together

One of the more surprising insights from our work is how strongly shared utilities can influence social connection. When residents understand that their building or neighbourhood runs on local solar, recycled water and smart grids, it often creates a sense of shared responsibility and pride.

Altogether’s experience shows that the most connected communities tend to make their infrastructure visible and understandable. Local energy centres, water treatment facilities and solar‑powered communal spaces become talking points, especially when paired with simple storytelling about emissions avoided or litres of water reused each year.

Education and engagement are critical here. Altogether invests in workshops, digital content and ongoing communication that demystify how embedded utilities work and what residents can do to get the best from them. That might mean explaining why smart meters matter, how to use recycled water safely in the garden, or what it means to live in a net zero‑ready precinct.

Insights that matter to developers and councils

For developers, embedded utilities are no longer just a nice‑to‑have feature – they are increasingly central to the commercial and planning logic of a project. Altogether’s data shows that well‑designed embedded networks and water systems can reduce operating costs, support higher sustainability ratings and differentiate development in a competitive market.

Altogether designs, owns and operates infrastructure for the long term, so we can bring early insights from 500+ neighbourhoods into masterplanning and precinct design. That might include right‑sizing decentralised plants, planning corridors for future‑proofed networks, or building in flexibility for regulatory changes around embedded networks and consumer protections.

For councils, the benefits show up in more resilient, circular local systems that support growth without putting the same pressure on centralised infrastructure. Local renewable generation, high rates of water reuse and transparent reporting on outcomes help align new precincts with regional sustainability strategies and net zero pathways.

From a planning and delivery point of view, the big takeaways are:

• Start utility planning early and treat energy, water and data as one integrated system.

• Use embedded utilities to unlock stronger sustainability outcomes and ratings.

• Choose partners who design, own and operate infrastructure for the long term.

Shaping the next generation of sustainable communities

Altogether’s journey, from our first recycled water community in 2018 to smart‑metered, net zero‑ready developments today, is giving the team a deep evidence base about what really works on the ground. By 2025, Altogether’s communities had helped avoid more than 20,000 tonnes of CO₂ and recycled over 2 billion litres of water, with thousands of households connected to local renewable networks.

Those metrics are important, but the bigger story lies in how we are influencing the next wave of precincts. New sustainable communities are being designed with deeper integration between power, water and data, stronger circular‑economy outcomes and more explicit resilience goals from day one. Embedded utilities are no longer just infrastructure in the background; they are becoming a defining feature of place, underpinning everything from EV charging to green open spaces and everyday affordability.

For any developer or council planning a new community, the key lesson from Altogether’s 500+ neighbourhoods is simple: start with the utilities if you want sustainability to be real, measurable and lived in every day.
