1
00:00:00,360 --> 00:00:01,480
Speaker 1: Jonesy and Amanda's.

2
00:00:02,880 --> 00:00:06,800
Speaker 2: Yesterday you were asking me about Warrigamber Dam, my favorite

3
00:00:06,800 --> 00:00:09,440
Speaker 2: piece of infrastructure, and you're just talking about what happens

4
00:00:09,440 --> 00:00:12,000
Speaker 2: if there's so much water, because it's spilling right now,

5
00:00:12,280 --> 00:00:16,200
Speaker 2: what happens if it gets inundated so much with the water?

6
00:00:16,600 --> 00:00:17,279
Speaker 1: Did I ask them?

7
00:00:17,520 --> 00:00:20,000
Speaker 2: You did? You? Did you ask that? You were asking

8
00:00:20,040 --> 00:00:23,440
Speaker 2: the question about what would happen with the spillway?

9
00:00:23,520 --> 00:00:25,520
Speaker 1: And okay, well if you say so, I don't think

10
00:00:25,560 --> 00:00:26,000
Speaker 1: I was.

11
00:00:26,040 --> 00:00:27,400
Speaker 2: So what you would like? A damn watch?

12
00:00:27,680 --> 00:00:28,440
Speaker 1: Did I say that?

13
00:00:28,520 --> 00:00:34,760
Speaker 2: Yes? You did? Damn watch down happening now?

14
00:00:34,920 --> 00:00:35,800
Speaker 1: Grank here.

15
00:00:35,840 --> 00:00:39,239
Speaker 2: I don't given Warrigamba Dam build in the forties, the

16
00:00:39,240 --> 00:00:41,480
Speaker 2: big daddy, that big daddy of them all eighty percent

17
00:00:41,520 --> 00:00:44,239
Speaker 2: of our drinking water and right now is spilling like

18
00:00:44,400 --> 00:00:45,360
Speaker 2: nobody's business.

19
00:00:45,440 --> 00:00:49,560
Speaker 1: We talked about this yesterday. It's drinking water and other usage.

20
00:00:49,640 --> 00:00:52,160
Speaker 1: You shower with it. I mean, this is what runs

21
00:00:52,159 --> 00:00:53,840
Speaker 1: the washing machine and all that.

22
00:00:53,760 --> 00:00:56,160
Speaker 2: Stuff to a car with it. Yeah, you do everything,

23
00:00:56,240 --> 00:00:56,600
Speaker 2: all the.

24
00:00:56,560 --> 00:00:59,320
Speaker 1: Ways we use water. It comes from Oregamba Dam.

25
00:00:59,320 --> 00:01:02,560
Speaker 2: And right now it's spilling four hundred and fifty gig

26
00:01:02,600 --> 00:01:05,080
Speaker 2: e liters a day, which is not much less than

27
00:01:05,080 --> 00:01:07,600
Speaker 2: the five hundred and sixty seven giga liters a day

28
00:01:07,800 --> 00:01:09,399
Speaker 2: that our population uses.

29
00:01:09,560 --> 00:01:11,840
Speaker 1: And that's so much it's spilling. And it's also spilling

30
00:01:12,480 --> 00:01:15,399
Speaker 1: the harbor, the Sydney Harbor, the amount of that it's

31
00:01:15,400 --> 00:01:16,400
Speaker 1: spilling every day.

32
00:01:16,480 --> 00:01:18,520
Speaker 2: So the question you're asking, what happens if it gets

33
00:01:18,520 --> 00:01:19,920
Speaker 2: totally inundated with water?

34
00:01:21,560 --> 00:01:22,320
Speaker 1: Why aren't we seeing that?

35
00:01:22,600 --> 00:01:24,800
Speaker 2: I'm glad you asked. No, we're not. We're not seeing

36
00:01:24,800 --> 00:01:27,560
Speaker 2: it right now. Back in nineteen eighty five, they had

37
00:01:27,760 --> 00:01:30,720
Speaker 2: a study and they were talking about the one in

38
00:01:30,840 --> 00:01:35,120
Speaker 2: one thousand chants of the annual exceedance probability or the

39
00:01:35,160 --> 00:01:39,119
Speaker 2: AEP don't you sorry? Is sorry? A one in one

40
00:01:39,160 --> 00:01:43,080
Speaker 2: thousand chance? So the water, if it's spilled over the

41
00:01:43,120 --> 00:01:46,480
Speaker 2: spill level, Now, okay, there we go.

42
00:01:46,600 --> 00:01:47,600
Speaker 1: There's maths involved.

43
00:01:47,600 --> 00:01:49,720
Speaker 2: You. If it goes over the top of the dam,

44
00:01:50,000 --> 00:01:53,120
Speaker 2: it compromises the dam and we can't control the outflow

45
00:01:53,200 --> 00:01:53,720
Speaker 2: of the water.

46
00:01:53,840 --> 00:01:54,800
Speaker 1: Isn't that what's happening now?

47
00:01:54,920 --> 00:01:57,200
Speaker 2: No, the water is in control. We are totally in

48
00:01:57,240 --> 00:02:00,520
Speaker 2: control of this thing right now. So the water's coming

49
00:02:00,560 --> 00:02:03,240
Speaker 2: down there. But if that water, imagine a bucket, if

50
00:02:03,280 --> 00:02:05,080
Speaker 2: you will, you're tipping water out of a bucket. It's

51
00:02:05,080 --> 00:02:06,360
Speaker 2: all going out of the nozzle. Yes, you know, when

52
00:02:06,360 --> 00:02:07,720
Speaker 2: you're up in the bucket had bit more and starts

53
00:02:07,720 --> 00:02:09,000
Speaker 2: to go over the edge of the so it's like

54
00:02:09,000 --> 00:02:11,880
Speaker 2: a giant bucket. So we have no control. That means

55
00:02:12,040 --> 00:02:15,320
Speaker 2: that the dam could eventually could wash away. So this

56
00:02:15,440 --> 00:02:17,880
Speaker 2: one in one thousand AEP.

57
00:02:17,800 --> 00:02:19,959
Speaker 1: Which we're not there now, no panic.

58
00:02:19,680 --> 00:02:21,799
Speaker 2: No, no, we're not. In ninety eighty five they got

59
00:02:21,800 --> 00:02:23,880
Speaker 2: together and I said, well, what we should do is

60
00:02:23,960 --> 00:02:28,080
Speaker 2: build a spillway to the right of the dam. So

61
00:02:28,200 --> 00:02:31,720
Speaker 2: that's if we're facing forward to the dam, that would

62
00:02:31,960 --> 00:02:35,840
Speaker 2: fix up if it was indeed to overflow. So the

63
00:02:35,880 --> 00:02:39,079
Speaker 2: spillway is quite ingenious. It was finished in nineteen ninety nine,

64
00:02:39,080 --> 00:02:42,840
Speaker 2: two thousand thereabouts. So what it has got these fuse

65
00:02:42,960 --> 00:02:47,520
Speaker 2: plugs up the top, these erodable rock and dirt mounds.

66
00:02:47,680 --> 00:02:50,600
Speaker 2: So if it does get above this what it's doing now,

67
00:02:51,120 --> 00:02:54,600
Speaker 2: those will erode away in an order and then the

68
00:02:54,600 --> 00:02:57,239
Speaker 2: water will come down the spillway and flow down the

69
00:02:57,320 --> 00:03:00,919
Speaker 2: river without There'll be consequence, is of course, because there's

70
00:03:00,960 --> 00:03:02,720
Speaker 2: a lot of water, but not as bad as the

71
00:03:02,800 --> 00:03:05,840
Speaker 2: damn collapsing. Did you know right now we're at a

72
00:03:05,880 --> 00:03:10,519
Speaker 2: one in seven fifty ap so one chance in seven

73
00:03:10,639 --> 00:03:12,880
Speaker 2: hundred and fifty, one chance in seven hundred.

74
00:03:12,680 --> 00:03:14,839
Speaker 1: And fifty years, and we've got that now.

75
00:03:14,919 --> 00:03:17,600
Speaker 2: That's happening now, so presumably.

76
00:03:17,080 --> 00:03:19,120
Speaker 1: It doesn't happen for another seven hundred and fifties. Will

77
00:03:19,160 --> 00:03:20,839
Speaker 1: we still be doing this show then? And can check?

78
00:03:21,040 --> 00:03:23,840
Speaker 2: I think we will, and we'll be playing bto and

79
00:03:23,880 --> 00:03:31,320
Speaker 2: we'll be happy. Excellent, damn watch dawn happening now. Rank here,

80
00:03:31,360 --> 00:03:34,840
Speaker 2: I don't give a day with join Z and Amanda
