1
00:00:00,720 --> 00:00:04,600
Speaker 1: Tis the season for roadworks Ashputten Council's infrastructure busses. Now

2
00:00:04,640 --> 00:00:07,680
Speaker 1: we can morning, Luke. So what have we got about

3
00:00:07,720 --> 00:00:10,960
Speaker 1: eighteen million worth of projects in the next few months.

4
00:00:11,320 --> 00:00:14,560
Speaker 2: Yes, certainly's got a lot to do, a lot of work,

5
00:00:15,120 --> 00:00:18,360
Speaker 2: a lot of road work underway. Yeah, and we'll make

6
00:00:18,360 --> 00:00:20,640
Speaker 2: full use of the good weather and get the work

7
00:00:20,680 --> 00:00:22,040
Speaker 2: done as soon as we can too.

8
00:00:22,120 --> 00:00:24,279
Speaker 1: Right. I know this is more a transit thing, but

9
00:00:24,480 --> 00:00:26,360
Speaker 1: you may have the inside scoop for us. Any word

10
00:00:26,360 --> 00:00:28,920
Speaker 1: on when they might start on that bit heading south

11
00:00:28,960 --> 00:00:30,680
Speaker 1: on State One out of Timbult, you know, past the

12
00:00:30,680 --> 00:00:33,880
Speaker 1: motor home yard, because man, that is bumpy. It's looking

13
00:00:33,920 --> 00:00:35,800
Speaker 1: like part of the Gaza Strip at moment.

14
00:00:36,320 --> 00:00:40,360
Speaker 2: Oh. Yeah, we've heard a lot of feedback about that. Unfortunately,

15
00:00:40,440 --> 00:00:44,920
Speaker 2: I don't know when they haven't given us the time. Yeah,

16
00:00:44,960 --> 00:00:45,479
Speaker 2: we never know.

17
00:00:46,040 --> 00:00:49,960
Speaker 1: It will keep it going. But for districts roads, I

18
00:00:50,080 --> 00:00:52,400
Speaker 1: was surprised reading this press release the other day that

19
00:00:53,080 --> 00:00:57,360
Speaker 1: Eshburton District is one of New Zealand's five biggest roading networks,

20
00:00:57,360 --> 00:00:58,960
Speaker 1: so that must be a challenge keeping on top of

21
00:00:59,000 --> 00:01:00,080
Speaker 1: all that.

22
00:01:00,080 --> 00:01:04,840
Speaker 2: That's correct. Yeah, it's about twenty five hundred kilometers and

23
00:01:05,160 --> 00:01:09,480
Speaker 2: it is a rather large network with also a big

24
00:01:09,560 --> 00:01:13,800
Speaker 2: unsealed network which is about fifteen or fifteen hundred and

25
00:01:13,840 --> 00:01:18,920
Speaker 2: sixty or something kilometers, so it is large when compared

26
00:01:18,920 --> 00:01:20,000
Speaker 2: to other councils.

27
00:01:20,840 --> 00:01:23,720
Speaker 1: Talking other councils, there was a fun story I think

28
00:01:23,800 --> 00:01:26,200
Speaker 1: was in the Guardian earlier this week that our neighbors

29
00:01:26,200 --> 00:01:30,000
Speaker 1: Selwyn are trial in New Zealand's first rubber roads. The

30
00:01:30,120 --> 00:01:33,480
Speaker 1: rubber quite literally hitting the road. Are you watching closely

31
00:01:33,600 --> 00:01:35,720
Speaker 1: thinking hmm, maybe this could work for us?

32
00:01:36,000 --> 00:01:39,360
Speaker 2: And yeah, now always interested in some innovation and if

33
00:01:39,360 --> 00:01:44,480
Speaker 2: there's any cost effective weal of ceiling roads and we're

34
00:01:44,600 --> 00:01:48,080
Speaker 2: certainly interested. We do know over the years there have

35
00:01:48,240 --> 00:01:53,320
Speaker 2: been various editives sort of crushed glass and I think

36
00:01:53,520 --> 00:01:57,160
Speaker 2: a rubber has been used trial before a few years ago.

37
00:01:57,240 --> 00:02:00,000
Speaker 2: That yeah, we're always happy to hear there is any

38
00:02:00,240 --> 00:02:03,040
Speaker 2: new way of doing things and we'll we'll be following

39
00:02:03,080 --> 00:02:04,040
Speaker 2: it with interest.

40
00:02:04,480 --> 00:02:07,000
Speaker 1: From on top of the water to under it out

41
00:02:07,040 --> 00:02:10,720
Speaker 1: to lake Hood. We've also spotted that there's about half

42
00:02:10,760 --> 00:02:14,000
Speaker 1: a dozen shipping containers that have gone and been submerged

43
00:02:14,040 --> 00:02:15,640
Speaker 1: in the in the canals. What's gone on here?

44
00:02:16,919 --> 00:02:19,600
Speaker 2: Yes, So the last three years at Lake Could we've

45
00:02:19,639 --> 00:02:25,840
Speaker 2: experienced elgall bloom and yeah, and it seems seems like

46
00:02:26,440 --> 00:02:29,519
Speaker 2: it's here to stay. And unfortunately, all around the world

47
00:02:30,240 --> 00:02:36,400
Speaker 2: there's no lake or ponds with signobacteria that where anyone's

48
00:02:36,440 --> 00:02:39,160
Speaker 2: managed to kill the signate bacteria and remove it. So

49
00:02:40,320 --> 00:02:42,520
Speaker 2: we've we've been looking at what we can do in

50
00:02:42,600 --> 00:02:45,799
Speaker 2: terms of mitigating the bloom and try and reduce the

51
00:02:46,680 --> 00:02:50,919
Speaker 2: algall from blooming into signobacteria and you know, causing us

52
00:02:50,919 --> 00:02:56,720
Speaker 2: to have you know, issues with safety warnings around and

53
00:02:57,840 --> 00:02:59,960
Speaker 2: as the readings get high and high and the warmer temperate,

54
00:03:00,280 --> 00:03:04,600
Speaker 2: So we tried last year circulating a lot of water

55
00:03:04,600 --> 00:03:06,920
Speaker 2: around the lake. We were very fortunate we had a

56
00:03:06,960 --> 00:03:10,320
Speaker 2: wet summer and the amount of water we had last

57
00:03:11,120 --> 00:03:13,560
Speaker 2: last summer that we managed to circulate and put around

58
00:03:13,600 --> 00:03:15,720
Speaker 2: the whole lake was more than double what we would

59
00:03:15,720 --> 00:03:19,240
Speaker 2: average it and get on an average year. Despite all

60
00:03:19,240 --> 00:03:23,560
Speaker 2: that extra water, we still had Signo bacteria the bloom

61
00:03:23,800 --> 00:03:29,519
Speaker 2: around about March earlier the year and it stayed until July.

62
00:03:29,720 --> 00:03:33,760
Speaker 2: So the Sina bacteria seems to be lingering longer each year.

63
00:03:33,880 --> 00:03:37,320
Speaker 2: So despite having so much more water and even creating

64
00:03:37,360 --> 00:03:40,600
Speaker 2: a channel that diverted it around the canals, so we've

65
00:03:40,640 --> 00:03:44,880
Speaker 2: engaged experts, scientists we've got We're very fortunate to have

66
00:03:45,080 --> 00:03:49,520
Speaker 2: Professor Susie Wood from Lincoln University who's regarded as a

67
00:03:49,560 --> 00:03:54,240
Speaker 2: world expert in toxic signo bacteria, so we've engaged with

68
00:03:54,280 --> 00:03:57,040
Speaker 2: her and she's she's got a PhD student, and there's

69
00:03:57,360 --> 00:04:01,640
Speaker 2: government funding to undertake research, and we're taking advantage of

70
00:04:01,640 --> 00:04:06,000
Speaker 2: that and doing a real good study on the lake,

71
00:04:07,000 --> 00:04:10,520
Speaker 2: creating a hydrodynamic model to understand how the water moves around,

72
00:04:10,760 --> 00:04:15,200
Speaker 2: what the nutrients are on the lake, the temperatures, dissolves oxygen,

73
00:04:16,200 --> 00:04:18,080
Speaker 2: all of that. But at the same time we also

74
00:04:18,120 --> 00:04:21,159
Speaker 2: decided to do a trial with the various products that

75
00:04:22,000 --> 00:04:27,920
Speaker 2: are around and see with these trials if there's any

76
00:04:28,440 --> 00:04:31,599
Speaker 2: cost effective product that we could apply to the lake

77
00:04:32,080 --> 00:04:36,480
Speaker 2: around about December January, which mitigates and stops the bloom

78
00:04:36,480 --> 00:04:37,200
Speaker 2: from developing.

79
00:04:37,360 --> 00:04:39,440
Speaker 1: So that's what the containers are for. We're trialing different

80
00:04:39,440 --> 00:04:41,360
Speaker 1: products in each one. That's right.

81
00:04:41,640 --> 00:04:44,480
Speaker 2: We had to get a cost effective way of trialing

82
00:04:44,520 --> 00:04:47,520
Speaker 2: something in the canal where there is the sinobacteria. This

83
00:04:47,680 --> 00:04:51,000
Speaker 2: is based in the seed beds at the bottom. There

84
00:04:51,040 --> 00:04:52,719
Speaker 2: is no point just taking the water out into a

85
00:04:52,760 --> 00:04:55,120
Speaker 2: pond and testing. You want to test it in the

86
00:04:55,200 --> 00:05:00,600
Speaker 2: environment that the cinobacteria is present. Thought about it and

87
00:05:00,640 --> 00:05:03,560
Speaker 2: came up with an engineering solution which was cost effective,

88
00:05:03,600 --> 00:05:08,120
Speaker 2: and got some secondhand containers cut out the top and

89
00:05:08,160 --> 00:05:12,080
Speaker 2: the bottom, and we've put them in the canal and

90
00:05:12,279 --> 00:05:16,040
Speaker 2: this morning we'll be applying the five different products that

91
00:05:16,440 --> 00:05:21,279
Speaker 2: Professor Wood has sort of decided on the fire that

92
00:05:21,320 --> 00:05:23,119
Speaker 2: we'll travel in this test.

93
00:05:23,560 --> 00:05:25,120
Speaker 1: Well, not just us, but it sounds like a lot

94
00:05:25,160 --> 00:05:27,479
Speaker 1: of people keeping tabs on this, and we sure hope

95
00:05:27,520 --> 00:05:30,120
Speaker 1: that something does work. Neil, We're Catt Chase for the update.
