Are any of the other two tanks in this system going to be removed as part of this
project?

Sheet PP2 shows the inlet, outlet and overflow locations in the plan view. Each of
these should have a note to indicate which one they are. Also, the outlet overflow
appears to be shown in this view. I assume that the drain and overflow will be
combined in the same drain location. This location should reference detail C on Sheet
D3 (I assume) also to ensure it is done correctly.
Notes have been added to Sheet PP2 to identify the inlet,
outlet, and overflow lines. Additionally, a detail reference
has been added to the drain location to ensure that it is
constructed correctly.
