The result is that wastewater is treated and reused locally, saving thousands of cubic metres of drinking water each year. It is precisely the kind of project the Circular Water Expert Group of the Water Alliance is keen to get its teeth into \u2014 particularly in light of the many challenges the Netherlands faces in the years ahead.<\/strong><\/p><\/p>\n\n<p><p style=\"font-weight: 400;\">\u201cLAB deserves credit as an area developer for what has now been achieved,\u201d says Joost Kreuger. In his day-to-day work, Kreuger is a projectmanager at Qua-vac and, in that capacity, also a member of the Water Alliance\u2019s Circular Water Expert Group. The group\u2019s mission is to accelerate the application of technologies that enable water to be reused in homes \u2014 and in businesses. Increasing the use of rainwater is another objective, all with the broader aim of reducing drinking water consumption and cutting energy use in and around the built environment.<\/p><\/p>\n\n<p><p style=\"font-weight: 400;\">Kreuger recalls the LAB project with evident pride. \u201cIn collaboration with, among others, WaterLab Circulair Water, Liander, Vitens and numerous companies, the site has become a genuine best practice in area development and circular water use,\u201d he says. For the technical realisation of the water chain, parties including Jotem, Rietland and Qua-vac joined forces. Rietland provided natural pre-treatment using its Phytoair system; Jotem delivered membrane and oxidation-based purification; and Qua-vac supplied the vacuum systems.<\/p><\/p>\n\n<h4 class=\"wp-block-heading\"><h4 style=\"font-weight: 400;\"><strong>Award for sustainable water use<\/strong><\/h4><\/h4>\n\n<p><p style=\"font-weight: 400;\">The outcome is the reuse of water for industrial processes and firefighting purposes, delivering significant savings in drinking water and energy, alongside a sharp reduction in discharges. The approach earned LAB the Sustainable Water Use Award from Vitens \u2014 a notable endorsement of circular thinking put into practice.<\/p><br\/><p style=\"font-weight: 400;\">\u201cThe project had several objectives,\u201d Kreuger explains. \u201cFirst and foremost, to maximise the reuse of wastewater, thereby reducing drinking water consumption. But we also wanted this case to demonstrate how a scalable and reproducible area-based approach can be applied to other business parks.\u201d<\/p><\/p>\n\n<h4 class=\"wp-block-heading\"><h4 style=\"font-weight: 400;\"><strong>Economies of scale<\/strong><\/h4><\/h4>\n\n<p>Given the scale of the construction challenges the Netherlands faces, Kreuger argues that an integrated approach to circular water is self-evident. \u201cYou achieve economies of scale by thinking beyond individual buildings and designing solutions for an entire area. That is what we did at LAB. We also ensured that water across the entire site could be reused.\u201d\nThis was made possible in part by Rietland\u2019s natural pre-treatment technology, which requires less energy and fewer chemicals. Jotem\u2019s nano-filtration and UV\/H\u2082O\u2082 oxidation processes also played a role, upgrading part of the treated water to a standard suitable for firefighting or industrial use.\n<\/p>\n\n<h4 class=\"wp-block-heading\"><h4 style=\"font-weight: 400;\"><strong>Vacuum sewerage<\/strong><\/h4><\/h4>\n\n<p>Dennis Meerburg, business developer at LAB, looks back on the project with satisfaction. \u201cWe save substantial volumes of drinking water by collecting it efficiently and purifying greywater on site. The remaining toilet water is propelled at high speed through narrow pipes using air pressure and minimal water \u2014 rather like the system used on aircraft. Transporting wastewater in this way is more compact and significantly less energy-intensive.\u201d<\/p>\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"49524\" src=\"https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-1024x683.jpg\" alt=\"\" class=\"wp-image-49524\" srcset=\"https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-1024x683.jpg 1024w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-300x200.jpg 300w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-768x512.jpg 768w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-1536x1024.jpg 1536w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-2048x1365.jpg 2048w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/3_LUCHTFOTO_LAB_FOTO-PLUIM-Fotografie-74-350x233.jpg 350w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Photo: Pluim Fotografie<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" data-id=\"49518\" src=\"https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-1024x768.jpg\" alt=\"\" class=\"wp-image-49518\" srcset=\"https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-1024x768.jpg 1024w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-300x225.jpg 300w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-768x576.jpg 768w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-1536x1152.jpg 1536w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-2048x1536.jpg 2048w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/2_QUA-VAC-SYSTEEM_IMG_2400-350x263.jpg 350w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"49516\" src=\"https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-1024x683.jpeg\" alt=\"\" class=\"wp-image-49516\" srcset=\"https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-1024x683.jpeg 1024w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-300x200.jpeg 300w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-768x512.jpeg 768w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-1536x1024.jpeg 1536w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-2048x1365.jpeg 2048w, https:\/\/wateralliance.nl\/wp-content\/uploads\/2026\/02\/1_Winnaar-Vitens-Award1-350x233.jpeg 350w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n<p>Photos: royalty-free<br data-start=\"20\" data-end=\"23\"\/>Aerial photographs: Pluim Fotografie<\/p>\n\n<h4 class=\"wp-block-heading\"><p style=\"font-weight: 400;\"><strong>WaterLab Circulair Water<\/strong><\/p><\/h4>\n\n<p><p style=\"font-weight: 400;\">With ambitious construction plans looming nationwide, LAB stands as a textbook example of how circular water technology can make sustainability tangible on business parks.
