CALL TO ORDER • Meeting called to order at 2:00 pm 2. APPROVAL OF AGENDA • Mario Valle made motion made to accept agenda. • Chris Mitchell seconded the motion. • All in favor. 3. NEW BUSINESS 4. OLD BUSINESS a. Revision to the Utilities Standard Manual David Schmitt: • We did listen to your comments last time. There was some concern about whether or not there was, what product perhaps this was written about, and after doing a little bit of research, this seems to be based upon the El pump specification. The drawing that accompanies it a little bit further back in the specification is also, if you look at it closely, it resembles the El. • Extra language developed by other consultants is considered as part of that. • Just a reminder this will be a deviation request. As you submit your information and so forth, you do have another product that you would propose as part of that deviation that would be considered as part of that. • No changes to the language. • This was a specification developed by another consultant that the county had employed to develop a specification for these private conversations. Some of the criteria is a little more specific. CPA manuals and so forth that describe how that thinking factor and some of the criteria was developed. • This is a deviation, so if you come in and propose something different, show your engineering calculations, then the county would look at that as a deviation and act on it as appropriate. Chris Mitchell: I think the question that we had, and I'm trying to remember back though, was by dividing by the 0.7 when you're looking at the peak flow, the peak flow is already accounting for a peak factor. So it was almost inconsistent with the public pump station, and so I don't disagree that you're finding higher peaking factor, because your population is a lot less going to the pump station if we're using the 10-state standards, but it seems like we're, it's inconsistent with what we do for the public list stations and it might be a little additional flow that it may change the size force power of the pump. It seemed to be, excessive isn't the right word, but it seems to be quite a bit more than the way that we calculated. So that was the concern. I get that the previous consultant did it, but I don't know if that's consistent with how we do it for Collier County Public Utilities. • This a private pump station and will always require a deviation. Matthew McLean: The designs of these things to try to make it consistent across the board. With it allowing the ability to have in the deviation process an engineer that may not want to utilize this guidance for how they want to lay out the design, they're certainly entitled to be able to come up with another way to look at it, but we would prefer to utilize this even though at the end of the day, it may be a little conservative. So, I don't see a need to change the language. • One study is 40 years, and another is 55 years. Project Record Documents • Highlighted in yellow underlined what we had before. • Revised highlighted in green. • Clarified that its county. • Consistent with what we discussed. • Connection to existing systems section 2500 there is a discussion on the installation A) #2 gravity system shall not contain vertical disc greater than one originally read one and a half in inches and we change that to one inch - 330518 Chris Mitchell: Asked what was the internal discussion? Because this was one of our points that we didn't think that it was necessary. You all requested that it not be changed, and then we held on the one inch. Matt McLean: When the team came back and spoke with me about this particular item, it's been more challenging for the utility just as a general conversation to this particular one. Now that the majority of the conveyance packages happened in the one step, we don't gain the benefit of being able to come back in a year and getting another gravity sewer tape from the developers to confirm that we've had additional settlement within the system. And so that was kind of the nexus overall of having to revisit this particular section. We're looking to try to make it a little bit tighter in there knowing that we do see some settlement over time and so for accepting things that we're at an inch and a half right away and then we lose another half an inch over the course of a year then we're in a situation where I'm gonna deal with a whole lot more ditch in there and take a look at our systems see what we're gonna do on fixing those sorts of things so that was kind of some of the additional conversations that we had internally. Chris Mitchell asked Matthew McLean: Do you have statistics on, I know that the process is new, but have you, how often in the two-step process will we have a lot of additional deflection? Matthew McLean: We are actually, we did have a significant amount of additional deflections, and I don't know if that was a function of two different people taking it at the time. I mean, we ultimately put the marker balls in there, which made it a lot easier to be able to determine how deep the dips are. And so that's been a good value add across the board. But when those things were happening, we already had the developer right there with us when it was two-step field, go ahead and address it and get it back up to within the inch. In this case now, since we went to an inch and a half to provide some more flexibility, but now we're losing that ability with the single conveyance step. Chris Mitchell: If it's an operational issue, we certainly don't want to create an operational issue that we know is going to be a failure down the line. I think for me, I would just caution that you guys are clearly going to go with an inch. Let's not get any tighter than that because it is construction and there's tolerances. It's really difficult sometimes to meet tolerance. • Section 331619 • You can see on the screen, the yellow is what we spoke about before, and the change is in green. • W-3. We revised the note top left, added note nine below. Installation of all fire hydrants shall be in accordance with all applicable Department of Transportation and local fire control district requirements. Then to the note on the top left of the page, urban C note nine and rural C note nine. • Detail W-12A, note number 8 was revised. Regarding temporary construction, fences shall be installed at water meter settings until building certificate of occupancy or installation of sod. The existing temporary construction fence shall be modified as necessitated by lot development. Fence to be three feet in height and offset three feet from assembly. Matt McLean: Anthony, what you're describing is that we went back to the original standard identifying that's already approved today of the minnow 18 inches and 22 inches. Anthony Stotts: Correct, and just added the language from Route 9 down there just to cover if there were any other conditions for as ape of the fire. • W-13. Add in note number 9 to equipment specifications including maintenance access to the county CEU or right of way. David Schmidt: We just added those notes on several different leader assembly, clarify the fact that it is already required. • W-14, the same thing. Add in note number 10 to equipment specifications, including maintenance, access, and county CEU are right away. W W-2, that's just a Scrivener's error. W W-3. added ASTM callouts, added mid -slab and sidewall thicknesses notes. • W W-4, the same thing, added ASTM callouts, added mid slab and side wall thickness notes. WW-5, again, added ASTM callouts, added VIN slab and sidewall thickness notes. Same changes, just clarification. W W-6, updated new required manhole dimensions, that was due to the DEB change. • Eight -inch wall thickness, line width, How long do these last? How long are the manholes without rehab? - It really all boils down to how much hydrogen sulfide we're experiencing in different areas of our overall system and how they're ultimately constructed. I mean, this wastewater and the hydrogen sulfide does eat away the liners and then gets into the concrete. Once you start getting into the concrete, that falls out and we get directly into the rebar, and typically with a properly constructed and installed manhole that doesn't have any chips and lining or any issues with it, they should last 50 to 60 years. Sometimes we have to go in at a 10 or a 20-year mark in certain cases where we're experiencing things that had some, what you didn't think were constructability issues or proper installation of liners. We've learned a lot about the liners over time, too, where we're getting better coatings on them than what we've had in the past. And we still have an incredible amount of manholes and wet wells that have no liners on them because they were installed prior to any of those time frames when you're looking at a 50, 60-year life. So, we rehab them. We typically focus the rehabs at the wet wells at the pump stations themselves because that's where we experience the most degradation just due to the fact that the material's sitting in them longer as opposed to a manhole. Typically, unless you're having an incredible amount of surcharge, and really experience a lot of issues with the manholes. • W W-7. few items on this one. Mark number three for access door was modified by adding opposite discharge piping. Also added to detail column. Mark number four was modified by adding the sentence no spacers permitted between check and plug valves. Mark number 7 was modified by adding the sentence RAMNAC may be used in lieu of O-ring rubber gaskets. See specification section 034100. Mark number 7 was modified by adding the sentence pump station wet well shall be designed by a Florida professional engineer and signed and sealed shop drawings shall be submitted. Mark number eight was modified by adding the text with external weight and lever. Added reference to plan sheets under profile call out section A -A. And the last one was added ASTM call outs, added no top slab eight -inch minimum thickness, revised footer dimension to A plus 32 inch minimum, added mark references. So, on item 7, we do not currently require a shop drawing to go in, correct? • I don't believe you send shop drawings and you guys review them and approve them. We get a shop drawing. Well, that's what they're saying. Part of the discussion we had last time, which I think is very valid, is that we are required to use your details. And we understand that that's the base minimum. But if we build a... what well, based on your detail, why do we have to submit a shop drawing? Matt McLean: Now, we review it because the contractor submits a shop drawing to us. Yeah, let me make sure that I'm understanding. I think that what I'in hearing, the concern is, is that with the language added, they're saying shop drawings shall be submitted, the clarification is to • W W-7D, private grinder pump station detail. This is the new detail added to the county set. David Schmidt, for the record, that detail goes hand in hand with the other changes that we had for the private pump stations. And again, if you look at the detail, it does reflect what you would see on D 1 pump station. Blair Foley: The detail itself talks about on the bottom right, concrete ballasting node seven. I think that may be node six. Could you guys go over the differences? We have two details. One's the standard, one's the... Oh, I'm sorry. There's just one. There's a misspelling. No, number nine receptacle is spelled wrong. That was the only difference. You guys did get the correction wrong? No, five. Sorry. • W W-8, pump station detail plan. Some of these are the same changes as the other pump station detail, but I'll read through them. Mark number four was modified by adding the sentence no spacers permitted between check and plug valves. Mark number eight was modified by adding the text with external weight and lever. Mark number 14 was modified by adding the sentence single door panels to open away from wet well. Call out for existing drive material was modified by deleting the option for grass covered porous pavement and leaving only the option for concrete or asphalt. Access drive dimension was set as the distance between the fence and the wet well top. Call out provide clear distance between fence and wet well top was added. • No added to section A -A referencing plan view on detail W W-7. No added next to dimension table to be completed by FOR I'm recommending G-E-O-R to engineer. • W W-AA. A lot of these comments are the same. I'll read through them. Mark number four was modified by adding the sentence, no spacers permitted between check and plug valves. Mark number seven was added fiber optic hand hole. See technical details specification 409500 and detail G-12 where applicable. Conflit and hand hole graphic added to the detail. Mark number eight was modified by adding the text with external weight lever. Mark number 10 was added IT telecommunications panel. See technical specifications 409, 500 and detailed G-12 where applicable. IT telecommunications graphic was added to the detail. Mark number 14 modified by adding the sentence single door panels to open away from wet well. Call out for access drive material was modified by deleting the option for grass covered porous pavement and leaving only the option for concrete or asphalt. Access drive dimension was set as the distance between the fence and the wet well top. Call out provide clear distance between fence and wet well top was added. Note added next to section A -A referencing plan view on detailed W W-7. And one more note added next to dimension table. We just spoke about to be completed by engineer. • Detail W W-8B. Again, a lot of these are the same mounts. I'll read through them. Mark number two was added fiber optic hand hole. See technical detail specification 409500 and detail G-12 where applicable. Conduit and hand hole graphic added to detail. Mark number four was modified by adding the sentence no spacers permitted between check and plug valves. Mark number 7 was added fiber optic hand -hull. See technical detail specifications 409-500 and detail G-12 where applicable. Conduit and hand -hull graphic added to the detail. Mark number 8 was modified by adding the text with external weight and lever. Mark number 14 was modified by adding the sentence single door panels to open away from the web well. Call -out for access drive material was modified by deleting the option for grass -covered porous pavement and leaving only the option for concrete or asphalt. An additional concrete post was added to the control panel. No add -index to dimension table will be to be completed by engineer. No add -index to section A -A referencing plan view on detailed W W-7. • WW-9, note number 3 was modified by adding the sentence single door panels to open away from wet well. Added callouts to detail square D power blocks to be installed in J-box and plastic unistra and cap callout. Note number 9 was added side panel penetrations are acceptable with the use of Myers hubs. Note number 10 was added phase monitor to be installed parallel with FP&L meter on FP&L side. Note number 11 was added Chico used to seal off and explosion proof fittings under JBOX, putty for all other conduit openings. Note number 12 was added. All unit struts to be mounted flush with post and penetrate post with stainless steel hardware. Note number 13 was added. All mounted equipment must be evenly spaced, level, plumbed, and installed in a work -them -like manner. Pump control conduit graphic brought forward in front of panel control conduit on detail. Thank you. Next please. Detailed W W-9A. Note number three was modified by adding the sentence single door panels to open away from wet well. Added additional concrete post graphic was added to the panel. Added call out to detail square D power blocks to be utilized in JBOX. Note number 8 was added, side panel penetrations are acceptable with the use of Meyers hubs. Note number 9 was added, phase monitor to be installed parallel with FP&L meter on FP&L side. Note number 10 was added, cheat code used to seal off an explosion proof fitting under JBOX, plenty for all other conduit openings. Updated detail to show fittings under control panel. Note number 11 was added, add emergency stop for generator and fire extinguisher on post furthest from generator with appropriate signage. Note number 12 was added, all units dressed to be mounted flush with post and penetrate post with stainless steel hardware. Note number 13 was added, all mounted equipment must be evenly spaced, level, plumbed, and installed in a workmanlike manner. Pump control conduit graphic brought forward in front of panel control conduit on detail. • Detail W W-9B, note number three was modified by adding the sentence single door panels to open away from wet well.

Note number 12 was added, all unit stress to be mounted flush with post and penetrate post with stainless steel hardware. And note number 13 was added, all mounted equipment must be evenly spaced, level, plumb, and installed in a workmanlike manner. W W-12. That was just a Scrivener error. Item number 102 was also Scrivener. That's just a webpage reference. Item 103, that was just modifying the table of contents. Item 104, Appendix B, Water Meter Sizing Form. The demand range table on the water meter sizing form page one was updated and taken from A W WA M22 table 6- 1, third edition. The flow ranges for three quarter inch, one inch, one and a half inch, and two-inch meter sizes are flow ranges for positive displacement meters. The flow ranges for three, four, six, eight, and ten -inch meter sizes are flow ranges for turbine class two meters. This table can vary depending on meter type. Modified language on signature line page one, replace stamp with seal. The fixture flow value worksheet page two was updated and taken from the Florida building code 2023 edition. Item 105, Appendix F, approved product list. Appendix F was revised to include new products that are to be placed on the approved product list. I just want to make a note on the meter boxes. We clarified in there which ones were for staff use versus the ones that we were expecting from the developers. Just to clarify that from the last meeting. And we also added the IQ boxes on there. They're a different color. Same box, different color. Item 106, appendix G, approved backflow devices. This is a list that was updated that they're using out in the field currently and items were updated to include lead-free models. And the last item, 107, Appendix H, IQ user application and agreement. Added basic user application and agreement for delivery and reuse of irrigation quality water. This is a form that currently Rob Kane's group is using, but the county wanted to implement it into the manual. Something that's currently in use. Chris Mitchell: It's been a long time since I've dealt with delivery of IQ, but is it more of a consistent delivery? It used to be that golf courses would, they're not promised delivery, even though there's the agreement. Are you guys more consistent with delivery? • We have a multitude of different I.Q. agreements with different users just due to the fact that some of them date back decades now. And as they come up for renewals, we're trying to get them more consistent across the board for the existing ones. But as far as the utility is concerned, consistent delivery of our irrigation quality water is one of our continued business models for expansion, particularly in the northeast section of the county where we're providing our services to villages and towns. A lot of those residential subdivisions and commercial areas as they become designed will be set up for the dual system, water and IQ. to balance out the system. It's a feast or famine in the IQ business because you either have too much or not enough. So, we do have supplemental well fields that are specific to the irrigation quality system too that may supplement in times where we have excess demand and not the ability to be able to provide all of that demand by way of just the effluent coming out of the water reclamation facility Matt McLean: I'd just like to personally thank the DSAC subcommittee meeting team for putting together the hard work on going through and reviewing these details and specifications that have been updated for us. • Do you want a recommendation from us in the subcommittee? We would. We would. We'd like to get a recommendation from the subcommittee, and then when we go present it at the formal DSAC committee meeting, we'll identify the few cleanup items that we had here today, and we're hopeful that we'll gain the support not only of you guys as a subcommittee with the recommendation here today, but also at the full DSAC committee meeting when we get on the next meeting that's available for us to present. Blair Foley: Made a Motion I'd like to recommend approval of the revised Collier County Large. Sewer Manual District Utility Standard Manual with a few corrections as it was presented today. Detail W W 7, remove the shop drawing language requirement. Detail W W7D, the ballast note is actually note 6, not 7. And then on W W-8, W W-8A, and detail W W-8B, remove the engineer record to engineer. And those are the small adjustments we'd like to see in the package presented to the full body of DSAC the first Wednesday of next month. That's my motion. Chris Mitchell: Seconded the Motion Chris Mitchell: I've heard from several clients that it's been very, very, very difficult with the fire districts and the way we have our acceptance set up and could we do a separate utility acceptance for fire. So, Lee County Utilities, I know they do a process for fire protection. And the hold is obviously no CO until you get final acceptance. Now what that does do though in the Lee County process is that you have the, you have DEP certification. So, it's operating as a system, but they can't get potable water until they get the CO and the site or the utility cert and CO so that you guys hold the meters or Lee County does. it's becoming a little more difficult to get fire protection. The fire districts are really clamped down. Matt McLean: At this time, based off the feedback from you being a DSAC member, we'll put it on our list, which is a very extensive list of upcoming potential updates. Not saying that it will ultimately get to fruition of becoming one, but we will certainly research it. Yeah, just set up a meeting with Anthony and our planning team and we can it down and understand more of the challenges that maybe you have and maybe we have a solution for it in our existing standards. I don't know yet. I don't know all the information at this time yet, but we're certainly willing to look into it. 5. PUBLIC SPEAKERS None 6. ADJOURN There being no further business for the good of the County, the meeting was adjourned by the order of the chairman at 3:12 p.m. COLLIER COUNTY DEVELOPMENT SERVICES ADVISORY COMMITTEE UTILITIES SUBCOMMITTEE Blair Foley, These minutes were approved byethe'Committee/Chairman on (check one) as submitted (. or as amended
