Sewerage and Drainage # 1979 Brigthon
Plastic as material for underground sewage systems has come to stay. During the last ten years, underground sewage pipes of PVC have come into such a use within the dimension range of 110 - 200 mm, that no other previous systems have succeeded in reaching in an equally short time. It is, however,possible to develop plastic pipes as well, and we know, that great efforts have been made all over the world to develop alternative pipes to the smooth conventional underground sewage pipe. One of the objects in mind has been to develop a pipe with at least the same good characteristics as those of smooth pipes but with a reduced weight. Now we have such an underground sewage system for sewage and rain water, and that is the LUBONYL DSA.
