However, successful implementation requires a lot of expertise and data in hydrogeological and geophysical conditions. With over 100 years of experience and 25 plants in operation, Finnish water sector has proven to provide sustainable solutions for MAR applications.<\/p>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\">Production rates in Finnish utilities are between 1 000 \u2013 65 000 m<sup>3<\/sup>\/d. Permits still allow production often up to 100 000 m<sup>3<\/sup>\/d, enabling cities to respond to needs of growing population.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\">Key technical aspects<\/h6>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\">Ponds are the most common method for infiltration. Also pre-treatment is used in some cases. Accurate 3D flow models provide in-depth knowledge of flow paths in the groundwater reservoir, allowing complete control of the system, even during extreme weather events. Flow rates in the aquifer and in the network can be further adjusted with mid-storages and reservoirs. Finally, disinfection is often done with UV or chlorine before pumping the water to supply network.<\/p>\n<\/div><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><br>Case example: Turku Region Water<\/h4>\n\n\n\n<figure class=\"wp-block-embed-youtube alignfull wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/dg1j16R0Tac?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=fi&#038;autohide=2&#038;start=330&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span>\n<\/div><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\"><br>Benefits of the system<\/h4>\n\n\n\n<div class=\"wp-block-media-text alignwide has-media-on-the-right is-stacked-on-mobile\" style=\"grid-template-columns:auto 30%\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"265\" height=\"259\" src=\"http:\/\/www.finnishwaterforum.fi\/wp\/en\/wp-content\/uploads\/sites\/6\/2019\/09\/kuva-1.png\" alt=\"\" class=\"wp-image-2859\"\/><\/figure><div class=\"wp-block-media-text__content\">\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>Safe solution for several common challenges <\/strong><br>&#8211; Raising or stabilizing groundwater level  <br>&#8211; Preventing saline intrusion or land subsidence <br>&#8211; Managing stormwater runoff and floods  <\/p>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>Cost-efficient technology for large scale water supply<\/strong><br>&#8211; Natural method with minor chemical use <br>&#8211; Easily automated and remotely controlled process <br>&#8211; Large sub-surface storage capacity<\/p>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>Sustainable way of managing water resources <\/strong><br>&#8211; Adapting to climate change <br>&#8211; Preparing for population growth <br>&#8211; Restoring and expanding the existing aquifer capacity <\/p>\n<\/div><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><br>Where we can help you <\/h4>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>Initial studies at potential production area <\/strong><br>&#8211; First observation wells and geological studies <\/p>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>Further research and feasibility studies  <\/strong><br>&#8211; Infiltration and pumping tests, 3D groundwater flow model <\/p>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>Turnkey MAR plant delivery<\/strong><br>&#8211; Design, Construction and Equipment <\/p>\n\n\n\n<p class=\"has-text-color has-very-dark-gray-color\"><strong>National scale-up and replication<\/strong><br>&#8211; Towards Sustainable Development Goals<\/p>\n\n\n\n<p style=\"text-align:center\" class=\"has-text-color has-normal-font-size has-very-dark-gray-color\">FWF members can provide all the required expertise for a MAR project. <br><a href=\"http:\/\/www.finnishwaterforum.fi\/wp\/en\/contact\/\">Contact us<\/a> to learn more about Finnish MAR expertise.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Applications in Finland Managed Aquifer Recharge (MAR) is a safe and cost-efficient method for production of drinking water.
