The separation and management of clean and polluted (dirty) water is one of the most important considerations for mining – especially for opencast mining.

Specific services include:

• Mine water balances
  › Forms the basis for the overall water management strategy
• Clean water diversion systems
  › Examples include: clean catchment diversion canals, river diversions and attenuation and storage
  dams
• Pollution control infrastructure
  › Examples include: collection canals (lined and unlined), silt traps and pollution control dams (lined
  and unlined)
• Water transfer infrastructure
  › Pump-stations, pumps and pipelines
• Water treatment
  › Silt and oil containment and management.
• Dam safety evaluations and audits
  › Dams classified as a dam with a safety risk in terms of the Dam Safety legislation requires
  design and sign-off by an APP (Approved Professional Person). Jones & Wagener has engineers
  who are registered APPs with DWA and can complete the designs and dam safety evaluations over
  the life of the dam.
• Design of water management infrastructure
  › Jones & Wagener’s Environmental Sciences prepares the EMPr(Environmental Management
  Programmes) and IWULA (Integrated Water Usage Licensing Application)
  › The water management infrastructure design forms an integral part of these applications and has
  several benefits to the implementation costs and timeframes.
• Re-instatement of streams over rehabilitated opencast mines
