A great deal of information can be gleaned from the material manufacturers handbooks that are available on the internet. Certainly Ductile Iron and mild steel cement lined pipe manuals are available from Tyco Australia. The Unibell handbook is a boible for PVC. PE is covered by various materials manufacturers such as Borealis, Phillips, Vinidex, Iplex. You can search the internet for the links. Apologies but some of these are based in Australia & Europe but are very useful.
Books by
Moser and
Watkins cover the aspects of buried pipelines design where there are considerations of a combined soil/pipe structure.
The AWWA has a number of standards worth considering.
In my field Pressure Transients in Water Engineering by Ellis is the bible. This is a specialised field but as a civil engineer involved in pipelines you need to understand what the specialist is interested in.
Haestad Methods put out a free CD of a book Advanced Modelling in Water Distribution. I do not know if this is still available now Bently own them.
Air valves are covered by
Non slam check valves by
AVK, Valmatic, Apco etc will cover most of your water industry valves but obviously there are many others.

If a response offends provide a little more explanation. Life is all too short to throw muck at each other.
