Update on Odour Issues in Waipukurau
To be released immediately 2 August 2017 MED201722
Since 9th June, CHB District Council has received a total of 310 responses to their request to complete the survey form regarding the odour issue. 230 responses were received in June and 80 in July indicating a significant reduction in the number of responses.
While actions undertaken to date have made a difference, we are aware the odour issue still remains and we are continuing to work hard to resolve the issue.
Dosing a suppressant to target hydrogen sulphide continues to be monitored and we are currently assessing the location of dosing to identify the most suitable dosing point.
Council has managed to source a Hydrogen Sulphide testing kit. These kits have arrived and are enabling staff to carry out individual tests with virtually instant results to assist with more effective dosing.
New sump bases have been installed at the bottom of the inlet to the pipes in Northumberland Street to prevent future accumulation of debris and stagnant water.
A meeting has taken place with a contractor to identify specific requirements for the installation of a provisional flare. Work is still needed to finalise designs.
Two further areas of pipe work will be CCTVed. The Old Hospital site on Porangahau Road will start today and the next area will be on the same three lines as completed in Mt Herbert Road between 29 Francis Drake Street and 100 Mt Herbert Road.
A site visit has been undertaken to assess the landscape work for the screen planting along the road frontage of the Wastewater Treatment Plant property and neighbouring boundaries. The targeted installation date is by the end of this month. The planting will include a higher canopy of totara and titoki and underplanting will include pittostrum and kowhai. This will also provide a natural habitat for birdlife.
Council is encouraging residents to continue completing the odour survey available on the Council website www.chbdc.gov.nz and report when odour issues are being detected. Council is continuing to correlate responses against findings from The Monitoring Trailer and carry out specific investigations in areas where odours have been detected.
Council would like to thank residents for their on-going patience and understanding while they continue to resolve the odour issue.
