Working closely with Sangwin personnel, the Wavin team was able to suggest beneficial amendments to the design. Their alternative suggestion demonstrated how time and cost could be reduced, whilst also enhancing performance. Unlike the originally specified system, the Wavin system allows lateral flow and is easily adaptable to avoid disturbing any buried services. Direct connection to the assembled storage tanks eliminated the need for an underlying feeder pipe. It also allowed units to be double-stacked, increasing each tank’s capacity and reducing its footprint, while keeping within the site constraints. This, in turn, meant one tank could be eliminated altogether, with savings in both time and cost of the plant, excavation and spoil removal.
