We have an unparalleled understanding of water treatment and conservation, allowing us to deliver site-specific, high value, and practical water sustainability solutions that provide the best outcomes.

We are an innovative team of scientists, engineers, and landscape architects, focussed on delivering project-specific, whole-water-cycle design solutions. We employ industry-leading technology to deliver design solutions that target zero energy consumption; closing the loop on water use and improving site efficiency. We have an unparalleled understanding of water treatment and conservation, allowing us to deliver site-specific, high value, and practical water sustainability solutions that provide the best outcomes for both our clients and the environment.

Committed to Continuous Improvement

At CJ Arms, we thoroughly research each project in order to provide appropriate water treatment options with a focus on feasibility and leading-edge design. Our culture is one of continuous improvement and lateral thinking. Our team of scientists are engaged in a constant endeavour to stay abreast of the latest research and development in all areas of water management, sustainability and treatment.

These ideas serve to feed our drive for innovation and help inspire us to achieve creative solutions which result in higher performance, improved water conservation and reduced energy consumption. Our prime objective is to always “create more with less”. Our unique multi-disciplinary approach allows us to combine our creative visions with proven engineering experience and sound scientific understanding. We leverage the diverse backgrounds, special interests and know-how of our team members to deliver on our ongoing commitment to creating successful water stories and redefining spaces.

Our Sustainable Design Philosophy

Our sustainable design philosophy ensures resilience and enables our systems to respond to the pressures of urbanisation and climate change. Our team of urban design experts deliver innovation and sustainability in integrated water management design. Our projects offer the very best in Water Sensitive Urban Design (WSUD), and sustainable wastewater, rainwater, and stormwater management.

We promote water reclamation, treatment, and reuse where appropriate, and look to reticulate harvested or recycled water for irrigation and other suitable purposes. The sustainable management of water mitigates negative stormwater impacts on buildings and the surrounding environment, and contributes to enhancing the public realm.

Through our revolutionary designs and integrated landscape solutions, we are able to improve amenity, health and well-being, bringing ecological sustainability to urban environments.
