Delivery of a 50.000-litre RoTerra 2450 underground tank that will operate as a grease separator. Made of HDPE, around 10,85 metres long and 2,4 metres wide, with three Ø600 access points and telescopic shafts, it arrived on site in a single piece and was unloaded and positioned with an excavator. Its oval shape and reinforcing ribs give it the strength needed to be buried, and the lightness of polyethylene makes transporting and placing a volume of this size much simpler.
