Rehabilitation and Closure

Earth Systems has the expertise and capability to provide site rehabilitation and closure planning advice for natural resource development projects (mining, hydropower) at all stages – from pre-feasibility to post-closure maintenance.  We offer our clients unique, site-specific and innovative solutions that are both financially and environmentally sound.  We believe that closure planning should start at the earliest phases of a project and have regular review and revision throughout the life of a project to ensure the most cost effective rehabilitation and closure program – and to minimise the potential for ‘surprises’ in the long-term.

We prepare rehabilitation and closure strategies that incorporate progressive rehabilitation throughout the life of a project to minimise closure liability and maximize end-use benefits. Where relevant, rehabilitation and closure strategies are developed in consultation with local communities and government authorities to ensure that their opinions and long-term plans are incorporated into closure planning.

Earth Systems also provides specialist expertise and emergency assistance for typical closure problems.  We have a proven track record in providing solutions for:

  • Sites containing acid generating waste materials.
  • Turbid, acidic or contaminated water bodies.
  • Management of post-closure water quality issues.
