A program for pollution abatement was undertaken to study the effects of infiltration reduction in sanitary sewers by joint sealing and to study closed circuit television techniques. Water pollution from municipal wastewater treatment plants would be reduced if peak flows from rainfall could be reduced. The study evaluates the effects of remedial repairs to joints by use of pressure grouting of small main line sewers. A minimal measurable amount of quantity flow reduction was attributed to the sewer sealing program. Infiltration from extraneous storm water, illegal connections, and basement underdrains seem to outweigh the contribution due to leaky joints to such a degree that reduction due to joint sealing was obscured. The study does show the significance of internal television system as an inspection and maintenance tool. This information on costs, operation, and procedure is of value to anyone interested in this field. (Author)
