The cost in the UK of corrosion of these structures has been estimated at four per cent of gross national product (GNP) per year (<a aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" href=\"http:\/\/www.icorr.org\/\" target=\"_blank\">Institute of Corrosion<\/a>).                 <\/p>\n\n\n\n<p>Some of this cost comes in the form of corrosion of underground iron structures (e.g. pipes), particularly in what are termed &#8216;aggressive soils&#8217;.                 <\/p>\n\n\n\n<p>This dataset identifies where the ground beneath the topsoil has potentially &#8216;corrosive&#8217; or &#8216;aggressive&#8217; characteristics and places them within the recognised scoring framework developed by the Cast Iron Pipe Research Association (CIPRA) \u2014 now the <a href=\"http:\/\/www.dipra.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">Ductile Iron Pipe Research Association<\/a> (DIPRA).                 <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is at risk and who might require this data?<\/h2>\n\n\n\n<p>Underground assets that are at risk from different types of corrosion include: <\/p>\n\n\n\n<ul>\n<li>building foundations, such as steel piles<\/li>\n\n\n\n<li>cabling<\/li>\n\n\n\n<li>earthing rods<\/li>\n\n\n\n<li>oil and gas pipelines<\/li>\n\n\n\n<li>sewers<\/li>\n\n\n\n<li>water pipelines<\/li>\n<\/ul>\n\n\n\n<p>This dataset can be utilised by a wide range of users such as:                 <\/p>\n\n\n\n<ul>\n<li>energy providers                     <\/li>\n\n\n\n<li>engineering and industrial insurers, including associations such as the <a href=\"https:\/\/www.imia.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">International Association of Engineering Insurers<\/a> (IMIA)                    <\/li>\n\n\n\n<li>local authorities and councils                     <\/li>\n\n\n\n<li>petrochemical companies                     <\/li>\n\n\n\n<li>regulatory and coordinating bodies                     <\/li>\n\n\n\n<li>transport infrastructure providers                     <\/li>\n\n\n\n<li>water companies                     <\/li>\n\n\n\n<li>water regulators and coordinating bodies such as <a href=\"https:\/\/www.water.org.uk\/\" target=\"_blank\" rel=\"noreferrer noopener\">Water UK<\/a> <\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Inspection\/testing prioritisation and project planning<\/h2>\n\n\n\n<p>All companies that have underground pipes are required to engage inline inspection testing to assess the state of the pipeline. The corrosivity dataset can be used as part of a risk-based approach to these inspections that takes into account ground conditions. This would result in prioritised inspection plans and, therefore, potentially reduce unnecessary inspections.                 <\/p>\n\n\n\n<p>The dataset can also be used by pipeline coordinating bodies that have a role to play in agreeing policy and actions and preventing incidents that could cause injury and damage the environment. Companies engaged in the distribution of electrical power (power, water or transport infrastructure) use earthing rods to ensure safety of the power supply. These earthing rods can be subject to corrosion under some types of ground conditions compromising safety.                 <\/p>\n\n\n\n<p>In addition, the dataset can be used in project planning and desk-study stages for new infrastructure, to identify the appropriate construction materials and level of preventative action that may be required. Examples of this include new infrastructure for renewable energy resources including solar, wind and wave.                 <\/p>\n\n\n\n<p>Corrosion alone does not cause pipes to fail. However, corrosion coupled with ground movement due to shrink\u2013swell, landslides and a variety of other physical geohazards will cause failure. We also licence a comprehensive set of <a href=\"https:\/\/www.bgs.ac.uk\/datasets\/geosure\/\">geohazard data<\/a> that can be used alongside the corrosivity data within asset management systems. <\/p>\n<\/div><\/div><\/div><\/section>\n\n\n\n\n\t\t\t\t\t<section   id=\"latest-content-6198-block_cad3d232f66b22feb1e8a1e2832c3469\" class=\"grid-section  primary-background   \" >\n\t\t\t\t\t\t<div class=\"container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"row header-of-section\">\n\t\t\t\t\t\t\t\t<div class=\"col-12\">\n\t\t\t\t\t\t\t\t\t<h2>You may also be interested in<\/h2>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"row grid-wrap\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"col-lg-6 col-12\">\n\t<div class=\"cards cards-orizontal-sm  cards-find-more  cards-bordered\">\n\t\t\t\t<a href=\"https:\/\/www.bgs.ac.uk\/geological-data\/datasets\/\" class=\"media-wrap\">\n\t\t\t<img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/01\/feature_250kSample-150x150.jpg\" class=\"lazy-blur wp-post-image\" alt=\"BGS Geology 250k sample\" data-src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/01\/feature_250kSample.jpg\" \/>\t\t\t\t\t<\/a>\n\t\t\t\t<div class=\"info-wrap\">\n\t\t\t<div class=\"info\">\n\t\t\t\t<h4><a href=\"https:\/\/www.bgs.ac.uk\/geological-data\/datasets\/\">Datasets<\/a><\/h4>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<p>We have a wide range of  licensed geoscience data.
