William Charles Easdale

William Charles Easdale was a British sanitary engineer best known for Sewage Disposal Works: Their Design and Construction, published in 1910. On the title page, he is identified as W. C. Easdale, M.S.E., M.R.San.I., and as the author of The Practical Management of Sewage Disposal Works.

In the preface to Sewage Disposal Works, Easdale explains that the book grew out of articles he had written for Surveying and the Civil Engineer. He reshaped that material into a practical reference book, aiming to give engineers and students a full guide to the design and construction methods then used in sewage-treatment works.

That background gives his writing a hands-on feel. Rather than treating sanitation as an abstract subject, Easdale focused on the tanks, filters, storm-water systems, and other working parts of disposal plants, making his books useful records of how public-health engineering was understood in the early 1900s.
