§ Mr. FowlerThe Water Pollution Research Laboratory is investigating the dispersion and behaviour of effluents discharged to the sea through pipe outfalls so as to provide an improved basis for the best economic design of such schemes. Full scale experiments are being carried out at two sites in addition to laboratory and mathematical studies. Although the initial work is being directed primarily to disposal of sewage much of it will be applicable to disposal of industrial effluents. In addition, both the Hydraulics Research Station and the Water Pollution Research Laboratory have carried out investigations of the disposal of both industrial and sewage effluents in a number of estuaries and it is hoped that this work will also lead to an improvement in the basis of design of disposal schemes.
