Reducing evaporation from water storages 
overcome barriers to the take up of increased water efficiency measures and water re-use would be welcomed eg. reuse of stormwater or wastewater from treatment plants (overcoming health department concerns); promote water conservation given regional climate; effectiveness of water tanks; types of lawn that minimise water use; management of rural land uses to minimise water use eg. viticulture industry
