Notes from meeting 3 May 2016
South Dunedin Action Group (SDAG) and mayor + senior management

Mayor Cull
– acknowledged that there was collective concern, that they were pleased to meet with the group and that the meeting provided the best place to provide clarifications
– Acknowledged that the process had been lengthy and frustrating, and “sloppy”
– Council was now very sceptical about evidence relating to the flood and had been let down. He added that they would not make any changes to anything without evidence.
– If the event occurred again even with the proper maintenance there would have been severe flooding
– Determined to make the system we have work the best that it can
– Agreed need another mechanism other than the ODT to communicate with the community
– Will consider the discussion and come back with a proposal for the next meeting with a smaller group

Laura McElhone. Group Manager Water and Waste
– All mudtanks had been cleaned in South Dunedin (marked with green spray)
– Screen has been redesigned at pumping station, work about to go to tender, installation expected July/August
– Screen currently cleaned weekly by contract with photograph for proof
– Proposed screen modifications would see a 4 part screen to allow for safer and easier cleaning – could not confirm bar spacing
– Approx. 100 manholes had been lifted (Oct/Nov 2015) to identify any siltation – none identified as a problem – map can be provided of manholes checked – this exercise will be repeated in Oct/Nov 2016
– Confirmed that with the work carried out or in progress expected reduction in level of water would be about 200mm – however difficult to predict because too many variable to undertake modelling
– On issue of foul sewage infiltration confirmed that work being undertaken in Kaikorai Valley was to reduce the pressure on the system before it came through to Caversham
– On the issue of diverting foul sewage to Green Island treatment works stated that it was only able to handle a certain amount as it had been set up for a different type of sewage
– With regard to pumping out to sea, confirmed that they now know who to contact at the ORC and will maintain valves to enable this to happen if necessary
– Advised Musselburgh pumping capacity cannot run at maximum [this is disputed by Darrel]
– Forecast received on 2 June was for 1/3 less rain – only after midday on 3 June did they receive prediction on the size of the event
– Definitely had contractors and staff monitoring and out in South Dunedin, but did not have enough people to cover the scale of event
– Door-knocking by DCC did not record the number of flooded houses [DCC has not been back to check]
– 1968 flood had two peaks so had time to recover [disputed by Darrel]
– Too many variables to accurately measure topographical data
– Understand need to reassure and quantify but have to be careful not to give false impression
– Advised that 4/5 engineers employed in planning and 6/7 at the delivery end – acknowledged the identified lack of a storm water specialist – currently under recruitment

Ruth Stokes. Infrastructure and Networks General Manager
– Contractors have been asked to verify status of periphery areas
– Need to build resilience in the community – have recognised need to contact secondary schools and community groups and extend beyond the ‘What’s the plan Stan” initiative

Sue Bidrose. Chief Executive
– Unable to provide a figure on the number of roads closed by DCC as the water washed the cones away.
– Civil defence, Fire and Police all advised DCC that only 20-30 houses had been flooded – suggested that volunteers sandbagging were not part of the information loop and therefore message did not get through to emergency services

Kate Wilson. Councillor
– Have been advocating for a rain radar for a number of years on the Taieri

David B-P. Councillor
– Not just South Dunedin affected but other areas also, we need answers to give the community reassurance that the system is operating
