The underground tanks we manufacture serve both to store drinking water and to compensate for temporary fluctuations due to changing water requirements. In addition, the tanks can also be used as water storage for fire extinguishing purposes and as tanks for storing excess rainwater.<\/p>\n<p>Our tanks are certified by the National Health Institute. The tanks are protected against corrosion on both sides. The inner surfaces of the tanks that come into contact with drinking water are protected by coatings certified by the Polish National Health Institute (PZH). A special thick layer of polyurethane primer enamel is applied to the outer surfaces of the tanks, which is suitable to be buried in the ground.<\/p>\n<p>We manufacture the tanks using our own documentation or the documentation entrusted to us by the customer. The underground tanks we manufacture can be placed on a foundation buried in the ground, a base made of compacted sand and cement or an embankment in the ground, depending on the soil and the water conditions. Our underground tanks are mostly cylindrical with a horizontal axis, closed with convex bottom plates in accordance with the standard PN-EN 12285-1.<\/p>\n<p>Below is a size chart for the main model series of underground water tanks we manufacture. We manufacture tanks with other, intermediate dimensions also.<\/p>\n<h4>Catalog sheets<\/h4>\n<ul>\n<li><a href=\"https:\/\/metal-zbiorniki.pl\/wp-content\/uploads\/2014\/06\/zrw.pdf\">Underground water tanks<\/a><\/li>\n<\/ul>\n<table>\n<caption>\u00a0<\/caption>\n<tbody>\n<tr>\n<th style=\"width: 61px;\">Type<\/th>\n<th style=\"width: 71px;\">Capacity [m<sub>3<\/sub>]<\/th>\n<th style=\"width: 76px;\">Diameter [mm]<\/th>\n<th style=\"width: 61px;\">Length [mm]<\/th>\n<th style=\"width: 132px;\">Diameter of the access hatch [mm]<\/th>\n<th style=\"width: 143px;\">Diameter of the drainage nozzle [mm]<\/th>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 5<\/td>\n<td style=\"width: 71px;\">5<\/td>\n<td style=\"width: 76px;\">1600<\/td>\n<td style=\"width: 61px;\">2800<\/td>\n<td style=\"width: 132px;\">500<\/td>\n<td style=\"width: 143px;\">80<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 10<\/td>\n<td style=\"width: 71px;\">10<\/td>\n<td style=\"width: 76px;\">2000<\/td>\n<td style=\"width: 61px;\">3660<\/td>\n<td style=\"width: 132px;\">500<\/td>\n<td style=\"width: 143px;\">80<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 20<\/td>\n<td style=\"width: 71px;\">20<\/td>\n<td style=\"width: 76px;\">2000<\/td>\n<td style=\"width: 61px;\">6660<\/td>\n<td style=\"width: 132px;\">600<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 25<\/td>\n<td style=\"width: 71px;\">25<\/td>\n<td style=\"width: 76px;\">2000<\/td>\n<td style=\"width: 61px;\">8000<\/td>\n<td style=\"width: 132px;\">600<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 30<\/td>\n<td style=\"width: 71px;\">30<\/td>\n<td style=\"width: 76px;\">2500<\/td>\n<td style=\"width: 61px;\">6000<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 40<\/td>\n<td style=\"width: 71px;\">40<\/td>\n<td style=\"width: 76px;\">2500<\/td>\n<td style=\"width: 61px;\">8000<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 50\/2.5<\/td>\n<td style=\"width: 71px;\">50<\/td>\n<td style=\"width: 76px;\">2500<\/td>\n<td style=\"width: 61px;\">10000<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 50\/2.9<\/td>\n<td style=\"width: 71px;\">50<\/td>\n<td style=\"width: 76px;\">2900<\/td>\n<td style=\"width: 61px;\">7500<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 80<\/td>\n<td style=\"width: 71px;\">80<\/td>\n<td style=\"width: 76px;\">2900<\/td>\n<td style=\"width: 61px;\">12000<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 100\/2.9<\/td>\n<td style=\"width: 71px;\">100<\/td>\n<td style=\"width: 76px;\">2900<\/td>\n<td style=\"width: 61px;\">15000<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<tr>\n<td style=\"width: 61px;\">ZRW 100\/3.0<\/td>\n<td style=\"width: 71px;\">100<\/td>\n<td style=\"width: 76px;\">3000<\/td>\n<td style=\"width: 61px;\">14000<\/td>\n<td style=\"width: 132px;\">700<\/td>\n<td style=\"width: 143px;\">100<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"text-align: center;\"><a href=\"https:\/\/metal-zbiorniki.pl\/wp-content\/uploads\/2014\/06\/p1273830.jpeg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"426\" class=\"size-large wp-image-103 alignnone\" src=\"https:\/\/metal-zbiorniki.pl\/wp-content\/uploads\/2014\/06\/p1273830-1024x426.jpeg\" alt=\"OLYMPUS DIGITAL CAMERA\" srcset=\"https:\/\/metal-zbiorniki.pl\/wp-content\/uploads\/2014\/06\/p1273830-1024x426.jpeg 1024w, https:\/\/metal-zbiorniki.pl\/wp-content\/uploads\/2014\/06\/p1273830-300x124.jpeg 300w, https:\/\/metal-zbiorniki.pl\/wp-content\/uploads\/2014\/06\/p1273830.jpeg 1100w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<h2>Tanks not included in the model series<\/h2>\n<p>At the customer&#8217;s request and after individual consultation we manufacture tanks with other dimensions.<\/p>","protected":false},"excerpt":{"rendered":"<p>They are used to store drinking water and to compensate for periodic fluctuations due to changing water requirements.<\/p>\n","protected":false},"author":1,"featured_media":371,"parent":8,"menu_order":80,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":""},"class_list":["post-14","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8.1 -
