WDM can be implemented in many ways with different policy tools being successful in a variety of contexts. These policy tools include market mechanisms such as economic pricing, non-market mechanisms such as the application of standards, quotas and fines on water use and direct intervention such as repairs to leaks, reduction of unaccounted-for-water and promotion of water efficient technologies. None of these methods should be seen in isolation and all form part of an integrated approach towards WDM.
