SUSTAINABILITY

Water management

Water is a shared and finite resource. We aim to preserve water sources, protect the waterways we use and support access to high-quality water.

Why this matters

Through good water management, we minimise our impact on water resources – for the benefit of local water users. 

For example, we:

Reduce, reuse and recycle water

By improving our water efficiency, we reduce our impact on local water supplies, especially in areas where supply is under stress.

of the water recycled at on-site facilities

Invest in community water schemes

Through investment in water-related programmes such as wells or filtration plants, we help communities gain access to high-quality water.

For example, in the Democratic Republic of Congo, we are partnering with a public water agency to upgrade water filtering for the city of Kolwezi.

spent on community water infrastructure in 2017

Manage water-related risks

Through effective risk management, we help preserve the quality of water we release into the environment, and preserve waterways we use for transporting commodities.

Our approach

We seek to understand our impact on the environment – using what we learn to minimise our impacts on water sources and the shared use of water.

To achieve this, we work with local water users, host communities and governments.

We have a Group water strategy. Through this strategy, we aim to:

  1. Identify and assess our material water impacts, risks and opportunities
  2. Improve our understanding of our water footprint
  3. Develop and implement water management plans covering the lifecycles of each of our assets – to avoid, minimise or mitigate the impacts and risks
  4. Improve our water management, including identifying and setting water-related targets
  5. Support continued engagement with significant stakeholders, and public reporting on our progress.

 

Our water balance

We seek to constantly improve our understanding of our water footprint; this underpins our water management strategy. 

We are working to better define the “water balance” at our assets – in other words, the water we consume, how much we withdraw from various sources, and where it goes – to support improvements in our monitoring, reporting and water management.

Principles we follow

UN Global Compact - Principles 7, 8 and 9

Principle 7: Businesses should support a precautionary approach to environmental challenges

Principle 8: Businesses should undertake initiatives to promote greater environmental responsibility

Principle 9: Business should encourage the development and diffusion of environmentally friendly technologies

UN Sustainable Development Goals - Goals 6, 12, 14 and 15

Goal 6: Ensure access to water and sanitation for all

Goal 12: Ensure sustainable consumption and production patterns

Goal 14: Conserve and sustainably use the oceans, seas and marine resources

Goal 15: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss

International Council on Mining and Metals - Principle 6

Principle 6: Pursue continual improvement in environmental performance issues, such as water stewardship, energy use and climate change

CDP

We participate in the CDP water programme.

Our progress

In 2017, we finished the harmonisation of our water reporting to align with the Water Accounting Framework of the Minerals Council of Australia – as part of our work to understand our “water balance” at each asset.

During the year, we made further progress against key strategic objectives in our water management framework, including: 

  • Establishing a guide for sharing best practices relating to water
  • Developing a briefing pack on the implementation of a catchment based approach
  • Completing and distributing a quick guide to our water reporting requirements
  • Refining our water balance tool.

 

Next steps

We will continue to implement our water management guideline, and will begin a pilot study, using the ICMM’s "catchment-based” approach to water management. We will also establish a platform to share best practice and learings across the group.
