Technical bulletin - Inland Waters Directorate ; no. 66 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Methods of abatement of pollution due to combined sewer overflows are critically examined. It is shown that the separation of sanitary and storm sewers may not yield the best solution in all cases, Some of the alternatives to sewer separation may be found to be more economical as well as more effective in reducing pollution. Possible alternatives to diminish volume or pollutional load of overflows by means of storage and treatment are described; The selection of the best abatement scheme will depend greatly on local conditions and will vary from situation to situation. Further research, especially on the treatment of overflows, is needed"--Summary. gccst Water pollution gccst Measurement Sewerage Canada. Environment Canada. Canada. Inland Waters Directorate.
