Water Resilience in a Changing Climate: How Local Water Recycling Keeps Communities Thriving

Water Resilience in a Changing Climate: How Local Water Recycling Keeps Communities Thriving

Across Australia, climate change is reshaping the way communities think about water. Longer, hotter summers, more frequent heatwaves and recurring droughts are putting pressure on traditional centralised water networks and dams. To keep communities liveable and sustainable, councils and developers are increasingly looking for local water solutions that can stand up to dry spells, support greener public spaces and reduce demand on precious drinking water.

Precinct‑scale recycled water and smart local infrastructure are emerging as some of the most powerful tools for building water resilience in new and growing communities. By capturing and reusing water closer to where it is used, these systems keep households, gardens and shared spaces thriving, even when the climate is working against us.

Why water resilience matters more than ever

Water resilience is about more than just having enough supply. It is the ability of a community’s water system to withstand shocks, such as droughts, heatwaves or restrictions, and continue to support everyday life, local ecosystems and economic activity.

For councils and developers, this matters because:

• Hotter, drier conditions increase demand for irrigation of parks, street trees and sports fields just as water restrictions tighten.

• Brown, dusty landscapes and dying trees undermine liveability, reduce property values and increase the urban heat island effect.

• Communities expect greener, more comfortable neighbourhoods that perform well on sustainability benchmarks such as BASIX and Green Star.

A resilient water system can adapt to these pressures while protecting potable supplies for essential uses like drinking, cooking and hygiene.

What is precinct‑scale recycled water?

Precinct‑scale recycled water systems treat wastewater and, in some locations, stormwater close to where it is generated, then return it for non‑drinking uses through a dedicated “purple pipe” network.

In an Altogether community, wastewater from bathrooms, laundries and kitchens is collected and sent to a Local Water Centre, where it is treated to high quality in line with the Australian Guidelines for Water Recycling 2006. The resulting recycled water is then supplied back to homes, businesses and shared spaces for uses such as:

• Garden and lawn irrigation

• Toilet flushing

• Washing machines and outdoor cleaning

• Watering parks, playgrounds and open spaces

Recycled water has its own network, so homes in these sustainable communities are typically dual‑reticulated, with separate drinking and recycled water supplies. This enables residents to save up to 70% of the drinking water they would normally use for non‑essential activities.

Building climate‑ready, sustainable communities

Local recycled water infrastructure delivers a suite of benefits that directly support climate resilience and community liveability.

Reliable water during droughts and restrictions

Unlike traditional systems that rely solely on central dams and catchments, precinct‑scale recycled water systems are designed to provide a dependable supply all year round. They reuse water that is already within the community’s own network; recycled water is not typically subject to the same restrictions as potable water during drought.

In recent dry periods, Altogether communities using recycled water were still able to water lawns, keep gardens green and wash cars long after drinking water restrictions saw other areas turn brown and dusty. This not only improves everyday quality of life but also preserves regional drinking water supplies for essential purposes.

Greener neighbourhoods and cooler urban environments

Access to a dedicated recycled water supply makes it easier to design generous landscaping from the outset, and to maintain it under tough conditions. Altogether’s local water networks capture, purify and reuse rain, storm and wastewater to keep parks, street trees and communal gardens irrigated all year.

This supports:

• Cooler, shaded streets and play areas during heatwaves

• Healthy open spaces for recreation and community connection

• Better biodiversity outcomes through more resilient vegetation

Greener, irrigated landscapes can significantly reduce local temperatures and improve comfort for residents, which is increasingly important as climate extremes intensify.

Reducing pressure on central networks

By providing local water solutions at the precinct level, developers can ease demand on regional drinking water and wastewater systems. Altogether communities have already recycled more than 1.2 billion litres of water, preserving potable supplies and reducing the volume of minimally treated wastewater discharged to oceans and waterways.

This system‑wide impact is particularly valuable for fast‑growing greenfield areas on the edge of cities, where existing infrastructure is already under strain. Combining local recycled water centres with smart networks creates a more distributed, flexible water system that can adapt as populations grow and climate patterns shift.

Smart water infrastructure: Data, control and optimisation

Today’s most effective water solutions do more than just recycle water, they use data and smart infrastructure to optimise how water is collected, stored and used.

Altogether’s integrated “power. water. data.” model shows how local systems can deliver efficiency, resilience and prosperity during droughts, floods and bushfires. By monitoring flows, storage levels and usage patterns across communities, smart systems can:

• Balance supply between recycled water, stormwater and potable sources

• Identify leaks or inefficiencies quickly

• Fine-tune pressure and distribution for different precincts

• Support proactive maintenance rather than reactive repairs

When combined with education, digital tools and simple guidance for residents, smart water infrastructure helps communities get the most from their recycled water systems and further reduce wastage.

Why councils and developers are embracing local water solutions

Precinct‑scale recycled water and smart infrastructure support strategic goals for councils, utilities and developers who are planning for a hotter, more water‑stressed future.

Key advantages include:

• Stronger sustainability performance

• Recycled water helps developments meet or exceed BASIX and Green Star benchmarks by significantly cutting potable water use.

• Altogether’s sustainable water networks can remove the need for individual rainwater tanks, simplifying design and saving space on lots.

• Enhanced liveability and place‑making

• Reliable non‑potable water supports greener streetscapes, active open spaces and high‑quality shared amenities.

• Cooler, greener environments build community pride, encourage outdoor activity and make precincts more attractive to residents and investors.

• Long‑term resilience and risk management

• Local systems reduce exposure to regional water restrictions, drought impacts and infrastructure bottlenecks.

• Diversifying water sources through recycling and stormwater harvesting improves security and flexibility over the life of the development.

• Environmental and emissions benefits

• Reusing water locally reduces the volume of wastewater that needs to be transported and treated at large central plants, lowering water‑related greenhouse gas emissions.

• Less discharge of minimally treated effluent into oceans and waterways helps protect coastal environments and local ecosystems.

These benefits align closely with the objectives of councils and planning authorities, who are seeking integrated, future‑proof solutions for growing communities.

A practical pathway to resilient, climate‑ready precincts

For councils and developers, moving from intention to implementation can feel complex. Partnering with an experienced local water utility provides a clear pathway from concept design through to long‑term operation.

Working with Altogether, project teams can:

• Assess site conditions and plan the location and scale of Local Water Centres within new precincts.

• Design dual‑reticulated networks that integrate recycled water, potable water and pressure sewer systems from day one.

• Model water demand, drought scenarios and growth to size infrastructure appropriately and ensure resilience over time.

• Align water solutions with broader sustainability strategies, including renewable energy and data‑driven building management.

Local water networks are embedded into the fabric of the community, they continue to deliver value for decades, supporting council water strategies, developer brand positioning and residents’ day‑to‑day experience.

Water resilience as a cornerstone of sustainable communities

As climate change accelerates, resilient water solutions are becoming as fundamental to community planning as transport, energy and housing. Precinct‑scale recycled water and smart local infrastructure offer a proven way to keep communities thriving through droughts and heatwaves, while protecting drinking water supplies and enriching local environments.

By capturing and reusing every possible drop, sustainable communities can enjoy greener gardens, cooler streets and more liveable neighbourhoods, today and for generations to come. For councils and developers seeking robust, future‑ready water solutions, local recycled water networks are no longer a nice‑to‑have; they are an essential part of building truly climate-ready places.
