The ACO story does not end in 1968, of course: it remains exciting right up to the present day. In the coming months, the ACO history wiki will be expanded step by step to include more history and stories from and about ACO.
At the end of the 1960s, surface drainage was still mostly point-based. This involved draining from individual gullies by way of buried drainage pipes. According to this approach, the water had to reach the lowest points on the surface, which was why cross gradients were required over large areas. The new concept of linear drainage using long drainage channels was the much more elegant solution.
