<br /> 880 that are in higher elevation in the cross-section so to speak of the depth below the surface,the
<br /> 881 impacts and levels and quantity of water in those higher up aquifers are not the same and not
<br /> 882 directly connected to and thereby affected by the disconnected much deeper aquifers. And so if
<br /> 883 that aquifer 200-foot, runs out of water, it is not the resultant cause of the lower aquifer drawing
<br /> 884 down, and similarly there's a possibility that that lower aquifer could run out of water in the context
<br /> 885 of the neighborhood and not have any effect on the 200-foot deep aquifers. And I guess the
<br /> 886 applicant can speak with regard to the private utility that's going to take over, upon approval and
<br /> 887 build-out of this proposed development,there's going to be a private utility that's going to take
<br /> 888 over the maintenance and ownership of this well system.And so, the supply of potable water to
<br /> 889 the users will, correct me if I'm wrong, be dependent upon that hired private sector utility.
<br /> 890
<br /> 891 Venkat Yendapalli: Well, thank you for answering the well and its impact to the adjacent wells. That part I'm not too
<br /> 892 concerned, because you clearly answered it, you're going at a different aquifer level,and bedrock
<br /> 893 is in between. My concern is predominantly on one well serving 49 homes and having a fault. If
<br /> 894 the one pump fails, the whole well will fail if it goes bad.
<br /> 895
<br /> 896 Ward Marotti: Well, I would go back and point to that private utility, because if that well itself, if the pump or
<br /> 897 another part of the hard infrastructure for that system fails,that utility is going to be there to fix it,
<br /> 898 whether it's a replacement of the pump or some of the piping or the conveyance system or
<br /> 899 whatever other utility component fails,the onus is on that private sector utility to replace that, and
<br /> 900 have implementation in a timely manner.
<br /> 901
<br /> 902 Beth Trahos: We have that slide, as well, that shows how much water exceeds the state requirements.
<br /> 903
<br /> 904 Ward Marotti: And I think, like you said,you're concerned with regard to capacity, and interaction between the
<br /> 905 aquifers isn't so much of a concern to you with regard to having provided that.
<br /> 906
<br /> 907 David Barcal: I'm David Barcal. Since we're doing the design of the well system,we can get to that, but, right
<br /> 908 now we'd be looking at a design by the public water sector, the number of connections you can
<br /> 909 have,you have to have .56 gallons per connection. We're proposing 1 gallon per connection. So,
<br /> 910 we're already doubling the draw of that, and then you look at your storage requirements,which
<br /> 911 you look at what you're drawing versus what your peak demands are. If you were to do those
<br /> 912 calculations,you'd have a minimal amount of storage required from the public water sector for
<br /> 913 this. Because it's going to be owned by a private utility, they require nothing less than a 5,400-
<br /> 914 gallon hydropneumatics tank. So,there's built-in storage within their storage tank onsite, and then
<br /> 915 like Ward was mentioning, they're going to be responsible much like if you have a utility and your
<br /> 916 water main breaks, they have to shut off that section of the water main, and that neighborhood all
<br /> 917 of a sudden doesn't have water. It's going to be the same—
<br /> 918
<br /> 919 Venkat Yendapalli: But here it's all one valve, and the pumps can go bad, and a lot of things can go bad here, like, the
<br /> 920 gentleman was touching on earlier, and the company,Aqua was referenced last time, I'm
<br /> 921 assuming,Aqua is involved here as well, and they have a lot of experience, but it takes time to
<br /> 922 restore the power water supply. It can't be done just like that, and I have seen it myself firsthand.
<br /> 923 Pulling a 600-feet deep well pump out and fixing it and putting back, it takes time.Anyway, I'm
<br /> 924 assuming that Environmental Health and other departments look into these in details. It's not the
<br /> 925 Planning Board's responsibility to vet those things here right here. But in general, I have a
<br /> 926 question on the septic fields and repair fields. Do you have any concept plans to share that they
<br /> 927 can be accommodated?
<br /> 928
<br /> 929 David Barcal: We did, so,we looked at the overall site, overlaid the usable green, conventional soils. Yellow is
<br /> 930 low-profile soils, so, still good for chamber systems, but we focused just on the conventional. So,
<br /> 931 we looked at four different sites and laid them out for four-bedroom homes, .25 LTAR,which is
<br /> 932 kind of a low end for conventional soils, and we were able to, at least using the survey data, lay
<br /> 933 the lines out on contour and make it work with all the setbacks, building footprints, Orange County
<br /> 934 setbacks to property lines, building foundations,driveways, tanks, that sort of thing.
