Wish there was something better out there.

Although this book is one of the largest information sources for WWTP design, it is also poorly formatted and illogical in presentation of material. The reason is because it is a compilation of many individuals so there is much redundancy, some conflicting information and incoherency in the overall text. If you are looking to LEARN how to design a WWTP you will need a good aid in addition to this text. Otherwise, it is fine if you know what you are looking for.
Good book, poor support

Metcalf and Eddy's Wastewater Engineering series is always good, but new editions of any book seem to have mistakes in the examples. The one that's bugging me ( it's the only one I've tried so far) is Example 4-10, concerning the time required to absorb a gas. The book gets a V value of 10; I get 1200. There's obviously something that needs explaining here, but I've been unable to get any help from either Metcalf & Eddy or McGraw Hill. My e-mails don't seem to get to anyone who can help, or they're being ignored.
It seems to be a good book, but if you have any questions you're on your own.
Very Good Reference

I found this book helpful in my preperation for the exam. It is a listed reference by NCEES, and will be useful for the exam and in practice.
The Wastewater Bible

I have used Metcalfe and Eddy's Wastewater Engineering from 3rd to 4th editions, and cannot think of a more comprehensive resource for all aspects of wastewater engineering from process design through to odour management through to water and sludge recycling.
The use of SI system in 4th edition is great and I agree with other users, the Bible is getting so big that it needs a searchable PDF to find references quickly.
The process equations have been updated to COD type design from older BOD standards, and allow for ease of process selection, with a good overview of strengths and weaknesses of each treatment type for attached growth, suspended processes and even advanced oxidation processes for removing remaining inorganics.
If there could be said to be a weakness perhaps there is one for tropical water temperatures of 32-35 degrees celcius, but this is dependant on the literature and research community due to lack of hi-tech development in the tropics.
I have tags on pages that are much used to speed access, wouldn't recommend students carry it as it is very big.
Unlike some expensive env engineering texts, this one is worth every penny.
Where's my book

Its very nice of you to e-mail me and ask for my comments, but I think it would be even nicer if I actually received the book. I am STILL waiting...
