<br /> 1168 some distance if we need to and also at some elevation if we need to. This collection system now is also small-
<br /> 1169 diameter pipe, so it's very unobtrusive in terms of how we put in the collection. We're able to follow the contour,
<br /> 1170 follow the roads. And John and I actually had gone through the development, and we had located where we would
<br /> 1171 put several of these STEP tanks to serve maybe a row of houses,one of the care facilities that Ed was just talking
<br /> 1172 about or larger versions of that same style tank to serve each of the multi-family units. In the end,we can bring those
<br /> 1173 lines together, and that was another detail that's there. It's called a STEP connection detail, and think about it almost
<br /> 1174 like a reverse water system. So, everybody's house that's on a community or municipal water system,that main
<br /> 1175 water line comes down through the road, and then we all have our water taps that feed into our individual house.
<br /> 1176 That's how they charge us, right? They go look at that meter. This is almost the same idea in the reverse. And so,
<br /> 1177 we have the STEP tank at the house,small-diameter line that goes to a STEP connection system,which is a back
<br /> 1178 flow, some ball valves, and now we have a common line. Again, generally, it's small-diameter, 2-, 3-inch-diameter,
<br /> 1179 generally not any larger than that. And we take that line,we bring it together and then we bring it over to our
<br /> 1180 treatment system. You referenced, ma'am, a MBR system, Membrane Bioreactor. Well,we're using on this, or
<br /> 1181 proposing, it's called a recirculating media filter. The actual product is called AdvanTex. I started designing with
<br /> 1182 AdvanTex back in, I think, 2006, 2007, somewhere in that ballpark. It has been permitted in North Carolina for use
<br /> 1183 since early 2000, about 2001. The AdvanTex technology is developed and manufactured by a company called
<br /> 1184 Orenco Systems that is out in the west coast, in Oregon. It's a very strong company. They're international. They've
<br /> 1185 got projects all over the place. Very, very large number of them are in North Carolina. We've worked with hundreds
<br /> 1186 of them in North Carolina. There's many of them,the same technology, in Orange County. We have designed,
<br /> 1187 permitted, helped to install,certified,we operate several systems with this same technology throughout Orange
<br /> 1188 County,throughout North Carolina, and we've even done some work in Virginia. But the technology is proven. It's a
<br /> 1189 great system for residential style waste, and it very, very much allows,when you have the ebbs and flows that come
<br /> 1190 with domestic waste products, houses,this type of system works very well with that. And part of the application is
<br /> 1191 actually a report that we had done several years ago,where we actually went in-and I will admit, I'm sometimes
<br /> 1192 skeptical of- I get sales people come to my office and say, Kevin,we see you do a lot of waste water work;we'd like
<br /> 1193 you to design with our system. And so,one of my first questions is,well, let me see your data. Is your system going
<br /> 1194 to work? Oh,yes,we have all this data from Utah, California. We have data from North Carolina, stuff that we have
<br /> 1195 operated that I have installed ourself. It's a recirculating media filter. It's an entirely different technology than an
<br /> 1196 MBR.
<br /> 1197
<br /> 1198 Marilyn Carter: Thank you, Mr. Davidson. I just wanted to understand if it was different from an MBR and that
<br /> 1199 doesn't mean MBRs, or the membrane bioreactors are bad. It just means that there are certain considerations that
<br /> 1200 we've all heard about in the public about the concerns about those kinds of systems in neighborhoods like Briar
<br /> 1201 Chapel and others that did not apply here. Is that correct?
<br /> 1202
<br /> 1203 Kevin Davidson: We are not using that system here. My colleague, Chris, knows even more about that system
<br /> 1204 than I do.
<br /> 1205
<br /> 1206 Marilyn Carter: All right. Thank you for that clarification,and I have another question, but I'm going to pass on
<br /> 1207 because I suspect my other question might get asked by someone else. Thank you, Mr. Chair, thank you.
<br /> 1208
<br /> 1209 Steven Kaufmann: I'm going to pass.
<br /> 1210
<br /> 1211 Lamar Proctor: Okay, I think it would be helpful if you could go back from my questions to the land-use pods
<br /> 1212 slide. I thought that was a very helpful diagram of proposed uses. If we can find it.
<br /> 1213
<br /> 1214 Scott Radway: There we go.
<br /> 1215
<br /> 1216 Lamar Proctor: So, my question in the center area where it's not designated that just says land-use pods.
<br /> 1217 What's the intention on that area of the property?
