In this context, the Intercommunale Namuroise de Services Publics (INASEP), as delegated project owner and represented by project engineer Jean-Marc SIMON, has appointed the company Decubel. Decubel specializes in, among other things, roadworks and sewerage projects.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A new sewer network<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cINASEP commissioned us to construct a completely new combined sewer system heading toward the future wastewater treatment plant,\u201d explains Julien Gonze, technical director at Decubel. \u201cOur task was to build the sewer network between the upper part of the village and the future treatment plant downstream, separating wastewater and rainwater.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Gres, a reliable choice<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For this project, INASEP recommended the use of vitrified clay pipes, a material that has been used for centuries and has become increasingly popular with intermunicipal utility companies in recent years. The choice of vitrified clay is due to its high wear resistance, making it more durable than concrete or metal, especially on routes with a significant elevation change.\n\n\u201cWe have been working with our supplier Euro Sweillem for vitrified clay pipes for three years now,\u201d says Samuel Mazzacavallo, sales representative at Deschacht. \u201cThe major advantage of vitrified clay is its wear resistance. It wears down much less quickly than concrete or metal when water flows down a slope. That is why vitrified clay is often specified for projects with large elevation differences.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A large-scale project<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The construction of the combined sewer system in Pesche stands out for the enormous quantity of materials used: more than 1,000 meters of vitrified clay pipes with a diameter of 300 mm and over 700 meters with a diameter of 400 mm. Although no engineering firm was involved, this project is special due to the rarity of vitrified clay and the exceptional dimensions of the pipes.\n\n\u201cWe supplied 1,020 meters of pipes with a diameter of 300 mm and 740 meters of pipes with a diameter of 400 mm. Everything was in stock, which allowed us to deliver quickly,\u201d adds Samuel Mazzacavallo.\n\nJulien Gonze of Decubel is very satisfied with the collaboration with Deschacht: \u201cFor me personally, this was the first time working with Deschacht, and I must say that everything went exceptionally well. We chose them because their products met the Qualiroute requirements, respected the Benor standard, and fit within the budget. In addition, we also ordered PP pipes and 160 mm fittings for the street gullies. Communication was excellent, delivery was fast, and Samuel, one of their sales representatives, even visited the site to take pictures.\u201d\n\nThis project illustrates our commitment to providing reliable and efficient solutions for large-scale projects. We are proud of our partnership with Decubel and our contribution to improving the infrastructure in the city of Couvin.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"46278\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-7.webp\" alt=\"Deschacht construction of sewerage with vitrified clay pipes 7\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"46276\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-6.webp\" alt=\"Deschacht installation of sewerage with vitrified clay pipes 6\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"46274\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-5.webp\" alt=\"Deschacht installation of sewerage with stoneware pipes 5\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"46272\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-4.webp\" alt=\"Deschacht installation of sewerage with stoneware pipes 4\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"46270\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-3.webp\" alt=\"Deschacht installation of sewerage with stoneware pipes 3\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"46268\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-2.webp\" alt=\"Deschacht installation of sewerage with vitrified clay pipes 2\"\/><\/figure>\n\n<\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-aanleg-riolering-met-gresbuizen-2.webp\" alt=\"Deschacht installation of sewerage with vitrified clay pipes 2\"\/><\/figure>","protected":false},"featured_media":2977,"template":"","meta":{"_acf_changed":false},"activiteiten":[174],"producten":[144],"class_list":["post-2971","realisaties","type-realisaties","status-publish","has-post-thumbnail","hentry","activiteiten-weg-en-rioolwerken","producten-gresbuizen"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Riolering met 1700 meter gresbuizen | Deschacht<\/title>\n<meta name=\"description\" content=\"Voor deze rioleringsaanleg werden meer dan 1700 meter gresbuizen geleverd.
