But other parts of the city have also been hit as it has got markedly worse this year.<\/p>\n<p>RNZ had requested interviews with Mauger, city council staff and councillors representing affected areas, but none had responded.<\/p>\n<p>Christchurch City Council was yet to answer questions on how the sewage would be treated before being pumped to the ocean and how long such a measure would be in effect.<\/p>\n<p>Community leaders and Canterbury Regional Council have been caught on the hop by Mauger&#8217;s announcement yesterday.<\/p>\n<p>Local community board deputy chair Jackie Simons only heard of the proposal yesterday.<\/p>\n<p>&#8220;This isn&#8217;t unusual,&#8221; she said.<\/p>\n<p>&#8220;It&#8217;s not good enough. I should have known that this was in the winds weeks ago.<\/p>\n<p>&#8220;I have people asking me questions about this before I have the information and as the elected representative that&#8217;s not a good thing. But at the same time, I do respect my council colleagues and council staff and what they are trying to do. I know that they are pulling out everything they can to try and resolve the situation.<\/p>\n<p>&#8220;It&#8217;s uncomfortable for everyone and the fact that I don&#8217;t get information ahead of time &#8211; it&#8217;s frustrating.&#8221;<\/p>\n<p>Simons said she was cautiously optimistic about the plan, but she had concerns.<\/p>\n<p>&#8220;There&#8217;s a lot of gaps. There&#8217;s a lot of information that hasn&#8217;t come through because it&#8217;ll be very detailed and very complex,&#8221; Simons said.<\/p>\n<p>&#8220;I&#8217;ve said I&#8217;m cautiously optimistic. I have concerns about it being discharged into our ocean because our ocean is literally not for that purpose. So I&#8217;m concerned about any harmful repercussions from discharging it to the ocean and I&#8217;m well aware that it has the potential to create problems along our coastline for people and for marine life.<\/p>\n<p>&#8220;At the same time I&#8217;m also dealing with a situation that has gone on for many years in the suburb of Bromley where our people are traumatised by ongoing odour.<\/p>\n<p>&#8220;There&#8217;s also younger people, and adults of course, who are having some fairly severe health impacts and it&#8217;s a very fine line to actually balance out doing something for the people without destroying our marine life. So cautiously optimistic is the word because I want our people to be better and to be able to get on and start living their lives.<\/p>\n<p>&#8220;It&#8217;s not an ideal solution by any means. But at this state in time what else do we have? I can&#8217;t see that we have any other solution.&#8221;<\/p>\n<p>Canterbury Regional Council director operations Brett Aldridge said he had many unanswered questions about the plan.<\/p>\n<p>&#8220;We had some very high level discussions around what the mayor proposed but only in a conceptual sense and so we were pretty surprised yesterday with the city coming out saying they were in consultation with us,&#8221; he said.<\/p>\n<p>&#8220;In saying that we do have a planned meeting and we will sit down and work through the proposal in a lot more detail. But at this stage we really don&#8217;t have much more detail than what the mayor announced yesterday.&#8221;<\/p>\n<p>Among the regional council&#8217;s unanswered questions was what partially treating the sewage meant.<\/p>\n<p>Aldridge said they were very interested in finding out what that process would look like.<\/p>\n<p>However he was certain it would not result in Christchurch facing a similar situation to Wellington, where about 70 million litres of wastewater was pumped into the ocean off the capital daily after its Moa Point wastewater treatment plant failed.<\/p>\n<p>&#8220;That would be a categoric no &#8211; I don&#8217;t think so at all,&#8221; Aldridge said.<\/p>\n<p>&#8220;We are not in the same emergency situation that Wellington is and we really would work through what&#8217;s being proposed and what are the mitigations that are going to be required to get it out there in a state that the effects are going to be well managed and mitigated.&#8221;<\/p>\n<p>Canterbury Regional Council would meet with Christchurch City Council on Wednesday to discuss the proposal.<\/p>\n<p><a href=\"https:\/\/radionz.us6.list-manage.com\/subscribe?u=211a938dcf3e634ba2427dde9&amp;id=b3d362e693\" rel=\"nofollow noopener\" target=\"_blank\">Sign up for Ng\u0101 Pitopito K\u014drero<\/a>, a daily newsletter curated by our editors and delivered straight to your inbox every weekday.<\/p>\n","protected":false},"excerpt":{"rendered":"The scent from the damaged plant has been plaguing much of Christchurch for years.
