The economics of the disposal of sewage and trade effluents.

In this review of the economics of the disposal of sewage and trade wastes, the author touches on all aspects of the subject, from the annual costs of sewerage and sewage-disposal services in England and Wales, and what he terms the "uneconomics" of pollution of natural waters, to the financing of capital expenditure on the construction of new sewage works and equipment and on alterations to existing works. He discusses the purposes and relative costs of the various processes in the treatment of domestic sewage and outlines the special problems involved in the disposal of trade wastes.
