Rod,
It looks like the submission includes the plans and specifications. It is also very helpful for me if there is a specific
response to my comments included, stating how each one was addressed and where in the plans or specs. This is so I
can focus on those items that I had questions about, and not have to review the entire plan set again. Below are those
comments again, if someone wants to include their responses below each one in a different color:
Paul, The drawings were significantly reworked, so most all of the detail numbering
has changed. My responses are in Blue as follows.

1) Air Vent detail 6 on Sheet C 5.0. (The Air Vent detail is now Detail 2 shown on Sheet
D5.0.)
a. Any pipes running through the roof or sidewall of a metal drinking
water storage tank shall be welded, or properly gasketed. In new
concrete tanks, these pipes shall be connected to standard wall
castings with seepage rings that have been poured in place. Vent
pipes, in addition to seepage rings, shall have raised concrete curbs
that direct water away from the vent pipe and are formed as a single
pour with the roof deck. There are now (2) air vents for the tank.
Both are 8" gooseneck type air-vents. They have a seep ring and
will be cast into an 8" x 8" roof deck/curb that is raised above roof-deck
of the tank.
b. The stainless-steel screen should be a #14 mesh screen. A #14 stainless
steel mesh and a #4 non-corrodible screen will be sandwiched between the 8"
flange and the 8" ring flange. In addition, there should be a large gauge
protective screen over the #14 screen.
c. What is the diameter of the air vent? The diameter of the air-vent is
8". There is no dimension showing that. The vent consists of 8" steel pipe that
will be hot-dip galvanized.
1) Detail 7, Sheet 5.1 shows the Outlet detail. To minimize potential sediment in
the flow from the tank, the outlet pipes from all tanks shall be located in a
manner to provide a silt trap prior to discharge into the distribution system.
This shows it level with the tank floor. The tank outlet is shown in Details 8
and 9 on Sheet D5.1. The Outlet pipe is raised 6" above the tank floor,
(providing a weir/slit trap) ant thereby minimizing the flow of sediments
out of the tank.
3) Detail 10, Sheet 5.1 shows the Inlet turned 90 degrees, I assume to promote
circulation. Will this be turned away from the outlet? This needs to be made clear in the
drawings. The tank inlet is shown in Details 8 and 10 on Sheet D5.1. The inlet piping
has a fittings that is turned 180-degrees (or away) from the tank outlet piping which
will promote mixing and circulation.
4) Is the tank going to be buried, as shown on the Vent Detail 6, Sheet 5.0 with 10
inches of earth cover? The tank will not be buried. This detail has been replaced. See
Detail 2, shown on Sheet D5.0. If so then it shall be elevated at least 18 inches above
any earthen cover over the tank. The frame shall be securely fastened and sealed to the
tank roof to prevent any liquid contaminant entering the tank. Concrete drinking water
storage tanks shall have raised curbs around access openings, formed and poured
continuously with the pouring of the roof, and sloped to direct water away from the
frame. The vent includes a raised curb and is the roof deck is also sloped to prevent
liquid contaminants from entering the tank. This vent and raised curb will be cast
into the roof of the tank.

5) The Bilco hatch on sheet C5.2 does not meet the Division of Drinking Water rules (I
assume this detail is intended for both hatches shown on the tank roof plan, Sheet S1.1).
The Bilco Roof Hatch detail has been replaced. See Detail 3 on Sheet D5.0. The
proposed hatch is Versa Hatch. It appears to have a handle and locking mechanism
through the surface of the lid and I can’t tell if there is a 2-inch shoebox overhang. Here
is the rule regarding access hatches:
a. The frame of any access opening shall be provided with a close-fitting,
solid shoebox-type cover that extends down around the frame at least 2
inches and is furnished with a gasket(s) between the lid and frame. Thehorizontal surface of the tank lid shall not have any openings, cracks, or
penetrations, such as a lock, key hole, or bolted handle that would
allow contaminants to enter the tank. It should also be lockable.
The Versa Hatch, as shown, does not have any openings,
cracks, locks, or keyholes or penetrations thru the lid
which would allow contaminants to enter the tank. The
hatch will be set on a 8"x8" curbed opening which is cast
into the roof-deck of the tank. The hatch is lockable
without any holes or penetrations into the inside of the
hatch.
6) I could not find the location where the outlet and drain from the tank terminate. They should terminate at a location (separately or combined) with a 12” to 24” freefalland a #4 screen on the end of the discharge pipe. A detail should be provided showingthis along with the location on the site plan.
The overflow and drain piping terminates an energy dissipation pool. The outlet into
the pool has a 21.5" free-flow air gap above the outlet of the pool. Please see Setails
5 & 6 on Sheet D5.1 as well as the Site Plan on C1.0, Grading and Drainage Plan Sheet
C2.0, and the Finished Grading Plan on Sheet C2.8, along with the Utility Plan on C3.0
I believe that I have addressed all the concerns enumerated. If there are any further
questions or concerns please feel free to contact me at
385-224-2196 or at [e-mail]
Shon

Dear Paul, please see attached the link for the revised plans and specifications for the Virgin Town East
Tank project. I understand that the revisions and edits that you sent have all been addressed. We look
forward to hearing back from you. We want to set the bidding and construction dates asap. Thank you for
all your assistance.
PS I did open these files earlier today, so I am hoping that it goes smoothly for you.

Paul,

Thanks for your prompt review and response to the drawings for the Virgin East Tank Project and thanks for taking my
call yesterday afternoon.

Based on your comments and our conversation I have made the following revisions. (I have numbered my responses
per your review comment numbering.)

1. I have corrected Detail 8 per your comment. It is now called out as 10” Tank Inlet Piping.
2. I removed the OSHA/ANSI A14.3 callout. Per OSHA, fixed ladders less than 24-ft in height do not require
platforms or cages. Currently the exterior ladder is 18-feet and includes a ladder railing. Per your concern and
request I added a 2 ft. x 30” handrail between the exterior ladder and the manway hatch. I added Detail 1.5 on
Sheet D5.0 to show the ladder, ladder railing, and the handrail, and manway hatch layout/configuration. Please
see Sheet D5.0 on the revised drawings.
3. The Versa Hatch that I have specified does include and meet the requirements you specified. I have included a
specification sheet herewith for your review and comment.
4. I revised the energy dissipation pool per your comment. Not only did I raise the tank overflow and drain lines, I
lowered the outlet piping for the pool. I also lowered the elevation for top of the embankment for the energy
dissipation pool. It now has a top of embankment elevation of 3728.80’. This now provides 1.2-feet of freefall
above the top of the embankment.

I have attached a link for the revised drawings, see below.

I trust that these changes will meet the requirement that you specified. Please let me know if you have any questions
or concerns.

Thank you again for your assistance.

Shon
