"The commentator traces the creation and importance of fresh water to man and introduces the concerns of the Wastewater Technology Centre at the Canada Centre for Inland Waters in Burlington. A girl enters the Wastewater Technology Centre building, and the commentator gives an overview of the facilities she tours. The centre's study of detergent phosphates is shown. The pilot application of the study at the Sludge Incineration and Chemical Recovery Field Station is recounted. The processing of a sludge and chemical flocculant slurry into chemical invitro ash is explained. Demonstration of the Lysimeter project shows the use of sludge for soil enrichment and the analysis of the resultant crop. The working of a sewage treatment plant is described. The Wastewater Technology Centre methods of treating municipal sewage through the removal of phosphate and nitrogen are shown. The pollutants produced by the pulp and paper industry are shown. A bench-scale experiment shows the investigation of biological treatment of pulp and paper wastes. The Petroleum Industries Wastewater Technology Centre facilities are shown, and followed by the analysis of the resulting effluent at the Centre. The uses of water by the mining industry are shown. At the Bathurst pilot plant the treatment of mine drainage with lime is shown. The Demonstration Trailer shows the mobility and applied research of the centre. The commentator makes conclusions as to the importance of the Wastewater Technology Centre research in the preservation of freshwater and the prevention of industrial sewage."

"Although Canada has the world's largest supply of fresh water, there is no room for complacency. This film shows the innovative technologies developed by the Wastewater Technology Center, inside its laboratories as well as at field pilot plant locations, in an effort to assist industrial and municipal water pollution abatement programs."
