    Gravity San. Sewer in Poor Soils and Groundwater

    I would not use RCP. I recommend using a lined DIP or PVC. Pour concrete ancors or caps to prevent floating. Also are you installing any manholes in this 400'?

    Spec on Air Release Valve Placement

    I work for a construction company who installs water mains and I just recently installed a few ARVs. You can go back later, if determined that an ARV is needed, and install them using a tap and wrap-around. An existing tee is not needed to install an ARV. Hope this helps you out a bit.
