Des­per­ate for de­cent drainage

Central Leader - - NEWS - By DANIELLE STREET

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.
