Hi Tom-
This plan got buried in my review pile and I finally got to it. A couple of issues to think about and address:
6\111. I can't get access to the Acme Shorey product line—do the mono tanks not come as 2 compartment?
/2. Sewer lines(4" and 2")will need to be sleeved over the water line
A��// Just a suggestion—we had a pin & block wall blow out a couple of summer's ago and there was no
74r stone/gravel/sand between the wall and the polyliner. Some of the engineers are designing gravel/peastone
A1/ between the liner and wall and also in the voids of the wall blocks to alleviate any water pressure against the
inside of the wall.
,14. Maximum feasible compliance does not allow a reduction to groundwater if you request a reduction of the leach
Vi capacity. I know there isn't much room to work with. We have approved less sand between the field edge and
the inside retaining wall since the side wall area isn't calculated towards the leach capacity. I am not sure if that
will get the full capacity you need if you expand the size of the leach field.
Let me know if you have any questions.
Thanks,Amy
