Iouriv Water Solutions Pty Ltd was established in mid 2000 as a specialist consulting and projectmanagement group to provide professional advice on the planning, design and delivery of water infrastructure in Australia and overseas.Stormwater harvesting is the collection, accumulation, treatment or purification, and storing of stormwater for its eventual reuse. It differs from rainwater harvesting as the runoff is collected from drains or creeks, rather than roofs. It can also include other catchment areas from man made surfaces, such as roads, or other urban environments such as parks, gardens and playing fields. Water that comes in contact with impervious surfaces becomes polluted and is denominated surface runoff. As the water travels more distance over impervious surfaces it collects an increasing amount of pollutants.The main challenge stormwater harvesting poses is the removal of pollutants in order to make this water available for reuse.
