The fine material was picked up with the tailwater from the reclamation site and pumped to a purpose built tailings facility adjacent to the reclamation.<\/p>\n<p>A key objective of the project was the creation of enough volume in the central tailings storage facility to enable continued operation of the quarry processing plants. Also, the material dredged was used to increase the amount of land available at the Penrith Lakes site for future urban development as an end use for the site after completion of the quarry activities.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ed61d8a elementor-widget elementor-widget-heading\" data-id=\"ed61d8a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Scope of Works<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a6d31c5 elementor-widget elementor-widget-text-editor\" data-id=\"a6d31c5\" data-element_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<ul>\n<li>Establishing a pipeline from the central tailings storage facility to Farleys Bay, a distance of 4,400 metres,<\/li>\n<li>Set up and maintenance of a tail water system to pump the fine material from the reclamation site,<\/li>\n<li>Establishment of a 1500 metre return water system to maintain adequate water levels for the dredge working in the central tailings facility,<\/li>\n<li>Dredge 1,300,000m3 of sand, silts and clays,<\/li>\n<li>Separation of tailings into two divided areas of Farleys Bay.&nbsp;
