The topics being discussed in the working group are:Focusing on updating the manhole details and specifications, including adding the option for precast bases.They also would be continuing to work on revising the pipe installation specifications and incorporating new pipe materials. This work would include getting the trench widths to match ASTM standards and updating terminology. City of Phoenix updated their supplement and included the term "foundation" to mean just the material under the pipe. This may require updates to MAG specs and details to be consistent.Phoenix would be looking at the more general water/sewer updates as possible cases for MAG.Flushing and testing requirements are an area that may be updated.
