Harbour sewage alert after deluge
and PAUL EASTON Saturday, 21 February 2009
A massivedownpour that brought a month's worth of rain in just a few hours has sparked health warnings after raw sewage poured into Wellington Harbour and Lyall Bay.
The downpour overwhelmed the city's drainage system yesterday morning sending untreated sewage into a street near Courtenay Place, a day before the entertainment zone holds the Cuba St Carnival parade.
The city copped 69 millimetres of rain yesterday, well over the expected entire February average of 62mm.
The overflow also sparked warnings about swimming at several beaches.
Wellington City Council spokesperson Richard MacLean confirmed last night that warning signs had been erected at Lyall Bay beach.
The lashing caused surface flooding and slowed traffic to a crawl, sparking a slew of accidents, and slips that blocked Rimutaka Hill Rd.
There were further discharges near the international passenger terminal and Kaiwharawhara stream which also discharges into the harbour.
Similar advisories were in place for Wellington Harbour after sewage diluted by stormwater was discharged at the long outfall at Moa Point.
"But it is very diluted sewage.
"People should probably stay out of the water," Mr MacLean said. The council would review results before lifting the warnings." Water quality testing would be carried out by council officials and Regional Public Health during the weekend. An "absolutely nauseating" smell had enveloped her property towards the bay's western end.
A Lyall Bay resident said the sewage had been leaking into the area for the past week."
The council spent $4 million on a stormwater upgrade in 2004 after a similar incident with sewage in Bond St in 2004. .
"Large amounts of fat are not supposed to get into the sewerage system so we'll be doing a check of grease traps in the area to make sure they're operating and being maintained properly.
Mr MacLean said the sewer blockage that resulted in untreated sewage spew near the intersection of Courtenay Place and Tory St was caused by a combination of the heavy rain and a buildup of congealed fat in the sewer.30am to complain."
StarMart manager Priyank Jain said he was first alerted to the spillage after customers came in to the store about 8.
The low was anchored off Westland yesterday.
Yesterday's onslaught came as a deep low brought warm moist air from the subtropics, MetService duty forecaster Oliver Druce said.
Mr Druce said the rain was forecast to ease in the North Island. An associated front sent heavy rain up the North Island.
