RE: Generator containment info
Geoff,
The original proposal was for the enclosure to drain to landscaping, but that was not possible because of
property boundary issues. Determining how and where the enclosure should drain will be site specific.
The shut-off valve is more like a ball valve, though I am not sure of the exact kind of valve they used (so,
no, not like a flood gate).
SUB would like to see an insert in the catch basin; however, the actual requirements come from the City,
not from SUB.
Please let me know if you have any other questions.
Amy

Hi Amy,
Thank you much for the cut-sheet. If I am understanding the excerpt below correctly, it looks like the Springfield Dialysis
project used a flood gate at the wall ofthe enclosure, which drained through the wall across the ground surface to an
adjacent catch basin. Please let me know if this sounds accurate, and let me know if the attached stop gate is similar to
the product used at Springfield Dialysis. Please also note that, for our project site, the existing catch basin that would
accept drainage from the generator enclosure is not currently fitted with a flo-guard insert. Would SUB require the
Cabela's project to add an insert to the existing catch basin?
Thank you,
Geoff Larsen, P.E.

Geoff,
Pasted below is an excerpt from the Springfield Dialysis HMMP that explains the set-up. I have attached
the spec sheet for the sub-base containment tray. I apologize that it is full of my notes from a telephone
call with the manufacturer. .
Back-up Generator and enclosure area (exterior):
The diesel fueled packaged engine generator has been designed wi
enclosurel fuel tank leak detector, su b~base containment tray, and.
foundation below the fuel tank/above the slab. The sealed and cur
gate that shall be kept open to allow for stormwater drainage to th
with a Flo~guard filter insert. During filling of the fuel tankl the OPl
gate to ensure that any spills shall be contained in the curbed area.
immediately if any spillage occurs during filling. A drain mat shall
stormwater catch basin in case of a spill. Before the flood gate is 0]
operator shall visually inspect the sealed slab for any spilled matel
instruction shall be posted on the generator. (See Appendix F)
