Desperate for decent drainage
Decades of troublesome flooding in a Hillsborough neighbourhood will soon end as Auckland Council prepares to install a new stormwater pipeline under the street.
Olsen Ave has a history of flooding dating back to the 1960s which has been attributed to the fact it lies in a basin created by lava flows.
The situation has been aggravated over the past 30 years as infill housing has increased.
Last August the Central Leader spoke to resident Tony Davies who has suffered through several metrehigh floods that had damaged his property.
Mr Davies had also noticed sewage was coming out of the manholes with the stormwater.
The manholes were replaced with heavier lids.
Now the Auckland Council has completed designs for a stormwater upgrade due to begin in early 2014.
The Central Leader understands the council has approved a 1.2-metre wide stormpipe that will feed into the 3-metre wide pipe under the southwestern motorway.
Construction is expected to take an estimated three months and will cost about $1 million.
A council spokesman says the pipeline will run through one private property, belonging to an Indian community group.
Consents for the work are well under way and the pipeline will be constructed using open trenches as opposed to tunnelling under any property, he says.
‘‘Auckland Council is working with the property owners to minimise disruption and ensure any concerns are taken into account when planning and delivering the project.’’
Mr Davies has been living in fear of the rain since he moved to Olsen Ave three years ago and is pleased the project is going ahead this summer.
‘‘I’m delighted because people have tried to have it fixed before and if they go ahead as early as next year that will be wonderful.
‘‘There is no question that it needs to be done,’’ he says.
Puketapapa Local Board chairman Richard Barter advocated for the stormwater mitigation and says the advances are good news for the residents.
Mr Barter says the board is also looking at improving other situations nearby where stormwater and wastewater have been mixing.
‘‘We are solving a number of problems in the area that are related,’’ he says.
‘‘And we are getting a commitment from Watercare and stormwater to do some longer term planning for good long-term solutions.’’
Watery woes: Flooded: Below, Tony Davies hopes Auckland Council’s plans to install a new stormwater pipeline will end flooding like this.
