With nearby watercourses, which include Werrington Creek and Werrington Lake Reserve, on-site detention assets are crucial for managing local stormwater flows.<\/p><p><a href=\"https:\/\/atlanstormwater.com\/au\/stormwater-detention\/\">On-site Stormwater Detention (OSD)<\/a> is a mainstay of water quantity management and temporarily stores stormwater runoff flowing from impervious surfaces in urban areas, such as roads, driveways and concrete paths. Detention systems are developmental requirements that reduce the impact of stormwater by controlling its movement and slowly discharging it to drainage systems, groundwater, or nearby waterways.<\/p><p>Four <a href=\"https:\/\/atlanstormwater.com\/au\/megavault\/\">Atlan MegaVault<\/a> systems will provide OSD across the estate with a combined volume of 3.2 megalitres (ML) \u2013 with individual volumes of 1.8ML, 0.71ML, 0.5ML, and 0.2ML. The MegaVault offers cost-effective, efficient stormwater management for medium to large-volume detention scenarios.<\/p><p>The MegaVault systems will be situated under bioretention systems on four corners of the site, allowing stormwater flows to infiltrate and slow. The assets will future proof the estate, protecting the community by preventing localised flooding in storm events and severe downpours.<\/p><p>Locally manufactured at <a href=\"https:\/\/atlanstormwater.com\/au\/in-house-manufacturing-capabilities\/\">Atlan\u2019s concrete facilities<\/a>, these precast concrete systems have a design life of 50 years. Each MegaVault features a 3-metre internal height with superior depth capabilities and has been designed with a high-volume vertical profile to reduce horizontal footprint.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-17126e9 elementor-align-center elementor-widget elementor-widget-button\" data-id=\"17126e9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/atlanstormwater.com\/au\/megavault\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Learn more about MegaVault<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-170d6f4 elementor-widget elementor-widget-text-editor\" data-id=\"170d6f4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>With their placement below the site&#8217;s bioretention systems, the design of these systems will maximise land yield \u2013 while meeting requirements for catchment size and flow rate. These generational assets are ideal for the available footprint with their ability to cater to large volume scenario &#8211; and their load-bearing structures will allow the continuation of above ground works<\/p><p>The MegaVault\u2019s modular, precast design and offsite fabrication ensure ease of installation, which reduces project timelines and aids engineers. These project efficiencies and expedited timelines are benefits of this cathedral-style detention system \u2013 which has no internal walls.<\/p><p>A 73-module, 1.8 megalitre system was the first installation on the site, which took four days to install. Subsequently, each tank will have similar installation times \u2013 compared to weeks to months to install cast-in-situ alternatives.<\/p><p>This modular design will see dramatic project efficiency gains across all four installations, reducing open excavation times and wet weather delays across the entire development. Fully trafficable, these systems also ensure aboveground works can continue.<\/p><p>A scalable OSD solution, the MegaVault is suitable for a full range of residential, commercial and industrial applications. With load ratings that accommodate heavy traffic, these modular systems are ideal for underground scenarios with allowances for overhead infrastructure \u2013 such as parklands, car parks and roads.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1c89d8b elementor-widget elementor-widget-image\" data-id=\"1c89d8b\"
