Care needed with water
As signs of a dry summer grow, Greater Wellington Regional Council is calling on residents to take extra care with their water use – especially for gardening and other outdoor uses.
Rainfall in November was well below normal in Wellington’s water supply catchments – including a record low total at Kaitoke in Upper Hutt – and river levels are suffering.
‘‘This could be a very tough summer for water supply, so I urge people to start going easy with water,’’ said councillor Nigel Wilson, chairman of the GWRC cultural and social wellbeing committee.
Rivers usually provide more than half of the water supply for Porirua, Wellington, and the Hutt Valley. But at the end of last month, flow at Kaitoke weir was just 17 per cent of its November average, and flow in the Wainuiomata River was 30 per cent of its November average. The Hutt aquifer’s level was at 97 per cent of its November average.
Mr Wilson said the most recent long-range summer climate outlook indicates average rainfall. But there is little sign of that so far, and he warned extra restrictions could be brought in before Christmas.
City council restrictions currently allow watering with unattended sprinklers and irrigation systems on alternate days, depending on house numbers, from 6am till 8am and from 7pm till 9pm.
