WINDHOEK, 22 JUL (NAMPA) Namibia, a pioneer in direct potable water re-use in the world, will host the Ninth International Water Association (IWA) Conference on Water Reclamation here in October this year.
The event is slated from 27 to 31 October 2013 at the Safari Hotel and Conference Centre, and will host about 450 water professionals and academics from the United States of America (USA), Europe, South America, Japan, China, Singapore, Australia, Mexico, and South Africa.
Conference chairperson, Piet du Pisani told Nampa on Monday Windhoek is the pioneer on direct drinkable water re-use, and the event will give Namibia the opportunity to showcase the Goreangab Water Reclamation Plant here.
The Plant was built in 1968 by the City of Windhoek to reclaim water directly from domestic sewage effluent.
Over the past 30 years the process was improved and the plants capacity extended to 2.9 millimetres per annum. Due to the fact that all naturally available water sources in and around the capital have been fully harnessed, the new plant was completed in 2002, and comprises the latest available proven water treatment technology. This was done in order to ensure the total utilisation of available effluent from domestic wastewater to ensure the security of water supply for the future. The new plant has been based on extensive experience, research done locally, and on input from international experts to assure the compliance to the strictest water quality guidelines applied internationally.
Reclaimed water, which is wastewater which has been treated to levels suitable for re-use, can provide a safe and reliable source for both non-potable and potable urban water supply.
Du Pisani noted that in the capital, direct potable reclamation, artificial aquifer recharge, water demand management and dual pipe irrigation systems have become part of standard vocabulary.
These processes had been embraced before the terms integrated water resource management and closing the water loop, had been coined.
The agenda of the conference include re-use in water resource management; water-energy nexus in water re-use; climate impacts on water re-use; science and technology in water reclamation; emerging pollutants and technological advances; groundwater replenishment and recovery; potable re-use as safe resource; desalination for water re-use; industrial and mining water re-use; economics of water re-use; regulation, governance and institutional arrangements for re-use; as well as human dimensions of water re-use.
Meanwhile, during the Global Sustainable Development Conference which took place in Brazil, Rio de Janeiro in June 2012, the City of Windhoek received thumbs-up for protecting water supplies and halting environmental degradation.
A report, which was issued by Local Governments for Sustainability (ICLEI) - founded in 1990 as the International Council for Local Environmental Initiatives - and the United Nations Environment Programme (UNEP) cited the City of Windhoek, which introduced an environmental management plan to protect the water supply at the Goreangab Dam from contamination by the mushrooming nearby informal settlements.
The Eighth International Conference on Water Reclamation and Re-use was held in Barcelona, Spain in September 2011.
