Excerpt from The Design, Construction and Maintenance of Sewage Disposal Works: Being a Practical Guide to Modern Methods of Sewage Purification In view of the fact that many millions of pounds sterling are spent annually on Sewage Disposal Works, it is obviously a matter of the utmost importance, in the interests both of economy and of the public health, that those who are entrusted with the design and construction of such works, or with the expenditure of public money upon them, should not only clearly understand the essential principles involved, but should also have at their disposal the latest results of contemporary experience to guide them in the practical application of those principles. The chemical and biological aspects of Sewage Disposal have been very fully and ably dealt with by a number of eminent scientific authorities, but no book has recently been published from which equally full and reliable information can be obtained regarding the more practical side of the question, considered from the point of view of the engineer, although the design and construction of Sewage Disposal Works are essentially the occupation of an Engineer, and Consulting Engineers engaged on this kind of work have unequalled opportunities for collecting information under widely varying conditions.
