Advances in the management of corrosion in sewers
04 April, 2013 by Ray Rootsey, Advanced Water Management Centre, The University of Queensland, St Lucia, Qld, AustraliaCorrosion of sewer assets is a worldwide phenomenon, particularly in countries with a warm climate. It is estimated that concrete sewer pipes in many areas of Australia are being corroded at an average rate of 1-3 mm per year or more. Hence, instead of providing service for 50 to 100 years as recorded in water utilities asset registers, sewer pipes are failing after 20 years or less. Internal surveys by several major water utilities in Australia show that the abnormally fast depreciation of assets and the mitigation of corrosion problems alone are costing the Australian water industry hundreds of millions of dollars a year.
