Global Water Challenge

BHP’s vision is for a water secure world by 2030. 


Water is an integral and vital resource for BHP’s production and operations. We cannot operate without it. We use water in many ways, but We know we have a responsibility to effectively manage our water interactions and avoid or minimize our potential or actual adverse impacts on water resources. We also recognize the importance of working with others to enable more effective water governance and stewardship across the communities, Local & Indigenous Business, regions, and countries where we operate. 


To make this vision a reality, we all have a role to play. That is why we have launched the “Global Water Challenge”, an international open call that seeks to identify and de-risk disruptive water treatment solutions to sustainably enhance water efficiencyand help us reach our sustainable development goals and commitments.


Now is the time for us all to think big and take action to tackle the challenges facing water. Effective water stewardship must begin within our operated assets. From there, we can more credibly collaborate with others toward solutions to shared water challenges as well as strengthen the relationship with Local & Indigenous communities through reciprocity and partnerships that will allow us to achieve mutual benefits for the future, aligned with our company purpose “Bringing People and Resources Together to Build a Better World”.

The awarded companies will be able to work together on the next steps for BHP such as a Proof of Concept, Controlled Environment Test and/or industrial pilot on a potential BHP asset.


At Enterprise Innovation & Decarb Procurement  of BHP, our objective as a sourcing function is to bring the best of the innovation world to BHP, to solve current problems that need a solution or optimization. The area enables an Open Innovation methodology at BHP to access technological and business capabilities to solve operational challenges. It does this by identifying and prioritizing critical business challenges, aligned with BHP’s priorities, and launching them to the market, not by specifying a product or service, but by asking for a solution. It then awards an on-site pilot to demonstrate that the solution is viable. 

Expande seeks to promote the development of ecosystems that allow the creation of virtuous circles between the challenges of the natural resources industry and innovative solutions from local and international companies. Under a model of open innovation and associativity, we seek that companies and suppliers capture value for their businesses through the incorporation and implementation of technologies.
