John,
I have looked at the tables you submitted to me and I am only seeing one results table for each water system.
For New Paria, it appears to be the fire flow, plus peak day demand (because there is a 20 psi min in the table), but no
demands are showing, so I don't know for sure). But some of the nodes are showing below 10 psi, so I am not sure this
meets the minimum requirements.
For Clark Bench, the results show really high pressure (between 80 psi and 100 psi), so I am not even sure which
pressure scenario was modeled and if the pumps or demands are applied correctly with such high pressures. With 1 gpm
per node, this may be peak day, but how did you come up with those demands.
Anyway, for hydraulic modeling, the following are helpful when showing that you have modeled things:
1) You should have junction tables for each of the demands and pressures for three scenarios shown below, if they apply
(for example, if there are no fire hydrants, then that scenario does not apply).
Fire flow plus peak day (meeting 20 psi minimum)
Peak Instantaneous flow (meeting 30 psi minimum)
Peak day flow (meeting 40 psi minimum)
2) For each water system, a small written narrative that explains how the demands are determined for each of the three
demand scenarios and a short summary of the modeling results, indicating that each meets the minimum pressure
requirements. If there are nodes (junctions) that don't meet the minimum pressures, then an explanation of why should
be included. It is also important in this written report, that you include the fire flow requirement set by the local fire
authority (if they have one) and you should have documentation in writing from the local fire authority about what the fire
flow requirement is.
I am not asking for a full hydraulic modeling elements report, but a short written summary of the results of all three
modeling scenarios for each system needs to be shown.

Paul,

I have attached the tables and maps of each systems water model. Also we are trying to coordinate scheduling with
KCWCD can you give us the timetable for when your review will be done?

Thanks,

Thanks.

I don't necessarily want the hydraulic model, just the tables showing demands, results for pressure at the nodes, pipe
lengths, and a summary of the results whether that be a map or a small write up with an explanation of the results.

Paul,
I think I can answer that. As you mention the drilling plans for Well 3 have already been reviewed. However, we
planned to drill the well and then size the pump for Well 3. We would anticipate a separate submittal for the
equipping of Well 3 that would include the drillers log, chemistry, and pump test data. You are correct in that this
submission presents the building that will house the electrical for the two wells and the booster pump.

We do have a hydraulic model and can provide that.

Thanks for your questions and please reach out with any others you might come across.

John and Dustyn,

Is the New Paria project submission also intended to include all of the well equipping information for Well #3 or is the
building modification and electrical intended for the combined well house for both Wells 2 and 3 and in preparation of
equipping Well #3? The reason I ask is because I am not seeing everything I would need for equipping Well #3 yet
(pump curve for the well, 24 hour constant rate test, new source chemistry, well drillers log, well grout witness). I
approved the drilling plans in August of this year, so maybe we just aren't there yet, which is fine since that will be
reviewed under a separate project file # (File #12564) and the remainder of the New Paria Project will be file #
13038.

My other question is that since you are creating a higher pressure zone with an upper tank, I think we talked about
the fact that the new booster pump station is intended to serve this higher pressure zone and move water through
that upper zone and to the new tank. With that being the case, this new area should have hydraulic modeling that
was done and it should also be included in these submittals to ensure all of the required pressures are being met.

What is the brand name and model of the chlorinators (specific make and model is helpful, ie, Regal gas chlorinator,
model ???)
Also, for New Paria, 100 gpm is from either one well or the other? In other words, they both pump to the same location
and are chlorinated there? Can you also describe the static mixer and its purpose? Typically, injecting water into a stream
of water in a pipe provides adequate mixing, so I am curious that this is for?

I believe it is a regal model 216.
Yes they both pump to the same location but only one well runs at a time. They both produce 100 gpm.
I believe we added the mixer for the purpose of getting the chlorine mixed as well as possible before being ran through
the booster pumps because concern was shown from the pump supplier about the chlorine possibly damaging the pumps.
John can correct me though if that was added for any other reason

Thank you!.
I assume that Well 3 for New Paria is "anticipated" to pump 100 gpm since it hasn't been drilled yet.

Conservancy District <[e-mail]>
John,
Following are my review comments on the New Paria Water Improvements Project. You called me as I was just getting
close to finishing up this review. I hope to have Clark Bench's comments this afternoon:
1) The plans show that they are 90% design and for review only. A final set of plans for construcon should be
provided.
Water Lines
2) The following are typical details or notes that are needed for the plans for water lines. My queson is are you
planning on using Kane County WCD’s water line standards? While these have been approved for their other water
systems (Duck Ck, Long Valley, Johnson Canyon), they have not been approved for this water system yet. But, as long
as those standards will be provided to the selected contractor, I am okay as long as that is what is happening.
· Soil type in pipe zone
· Disinfecon
· Pressure tesng
· Valves
· Fire Hydrants
· Service connecons
Well Discharge Piping
3) You have provided a well pump curve on Sheet G5. I assume it is for the exisng well pump since the new one has
not been drilled yet. I will comment on the discharge piping on Sheet BLDG1 now since it will be used by both wells.
· Is Detail A/D2 meant to be the detail for the pump to waste line? If so this should be added to the note
on Sheet BLDG1 that points to this.
· Is there a Shut off valve on the line going to the low pressure system? There is one going to the booster
pumps, but not to this part of the system?
Booster Pump
4) Is this booster pump staon intended to just move water to the new tank in the upper zone and not for providing
pressure to the zone exclusively?
5) The specificaons indicate that you are planning on using the Tigerflow, CDF 15-2 pump skid. You show two
pumps, are they redundant and both 5 HP, 100 gpm or is that the combined flow of both pumps.
6) For the booster pump staon, the sucon side of pumps needs to have a compound gauge (measure both posive
and negave pressure) and discharge side with a standard gauge. I can see gauges on the BLDG1 drawing, they are
just not specified so I want to make sure this pump skid has those proper gauges.

Chlorinator
7) What is the make and model of chlorinator, Regal and what Model?
8) Screen on Detail C/D1 for chlorinator vent should be a #14 screen, not a #4 screen.
9) Separate switches are required outside of the chlorine room for fans and lights? Has it been designed that way?

https://mail.google.com/mail/u/0/?ik=f3bcb897f8&view=pt&search=all&permthid=thread-a:r-3588349672499144025&simpl=msg-a:r-40980090159794…2/2
10) There is no profile view of the chlorinator room nor details of venng locaons by elevaon. You need to ensure
that exhaust vent takes from near the floor and the air intake louvers are near the ceiling.

Tank
11) The descripon of the project calls the tank as a 150,000-gallon tank, but the plans show 0.16 MG tank (160,000
gallons). Please clarify.
12) Sheet S1.1 should show the required slope of the roof and floors in Detail B (or another appropriate detail). They
are in other minor details, but this one would be best to show that requirement to ensure it is not missed to allow
proper draining of the tank interior and the roof.
13) The air vent pipe penetraon shall meet the following from the rule:
Vent pipes, in addion 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.
14) The air vent detail 119 on Sheet S3.4 does not show how high above the covered tank surface it needs to be. The
DDW rule requires that with a buried tank (as indicated on this detail), that air vent should be a minimum of 24 inches
above the covered surface.
15) The access hatch needs to have enough detail to show the minimum requirements that it is raised up at least 4
inches above the concrete curb, with a 2-inch shoebox close fing downturn, lockable, and has a gasket on the
underside with no penetraons through the hatch lid.
16) The hatch details on Sheet S3.5 don’t show a dimension of how high the curbing should be. As indicated in the
comment about the air vent, there is a detail that shows the tank to have cover. If that is the case, then the hatch
curbing is required to be raised a minimum of 18 inches above the soil cover.
17) Is the Drain Detail A/D2 meant to be used for the overflow and drain from the tank? Are the drain and overflow
combined? Just want to be sure this is clear.
Let me know if you have any questions
Paul
