News from Greater Wellington Regional Council
It was a record-breaking day today – water use was well below the target for maximum daily use and the lowest amount supplied since records began in 1997. (The previous lowest day on record was 112ML on 30 December 2012).

Daily target water use (maximum) = 130 million litres (ML)
Today’s water use = 106ML
Change from Friday = lower by 11ML¹

The weather forecast outlook shows some rain from Wednesday. The timing of the next significant rainfall is central to when we can recommend easing the water use restrictions.

News from Greater Wellington Regional Council – March 29
Friday’s water use = 120ML
Change from Thursday = higher by 1ML

Water use was below the target for maximum daily use today. We thank all water users for their continuing efforts to conserve water.

River flow rates remain well below long-term March averages. River-flow recession rates are flattening out a little better than we had anticipated earlier in the week. Without further rainfall and at current levels of water use, we now expect to meet demand without having to use storage into mid-April.

The weather forecast now shows only some showers next week. The timing of the next significant rainfall is central to when we can recommend easing the present water use restrictions.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Lower demand helps to preserve our water reserves longer.

Friday’s water supply came from:
Rivers: 76ML
Hutt aquifer: 44ML

Lake 2 remains 100% full. The outdoor water use ban remains active.

News from Greater Wellington Regional Council – March 28
Daily target water use (maximum) = 130 million litres (ML)
Thursday’s water use = 119ML
Change from Wednesday = lower by 11ML
Wednesday’s water use = 130ML
Change from Tuesday = higher by 4ML

Water use today (Thursday) was below the target for maximum daily use, and on Wednesday it was equal to the target. We thank all water users for their continuing efforts to conserve water.

River flow rates remain well below long-term March averages. River-flow recession rates are flattening out a little better than we had anticipated earlier in the week. Without further rainfall and at current levels of water use, we now expect to meet demand without having to use storage into mid-April.

The 14-day weather outlook now shows six consecutive days with some rainfall, from Friday 5 April. However, experience has shown that we can’t yet count on this arriving. The timing of the next significant rainfall is central to when we can recommend easing the present water use restrictions.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Lower demand helps to preserve our water reserves longer.

Wednesday’s water supply came from:
Rivers: 90ML
Hutt aquifer: 38ML
Storage: decreased by 2ML (within the Regional Council’s distribution network reservoirs)
Storage in Lake 2 remains 100% full

The outdoor water use ban remains active.

News from Greater Wellington Regional Council – March 27
Daily target water use (maximum) = 130 million litres (ML)
Tuesday’s water use = 126ML
Change from Monday = lower by 2ML
Water use was again just below the target for maximum daily use yesterday. We thank all water users for their continuing efforts to conserve water.

River flow rates remain well below long-term March averages. River-flow recession rates now indicate that without further rainfall we could be back to low pre-rain flows in about 8-10 days.

The outlook for rain remains changeable from day to day, with only two wet days indicated in the latest 14-day weather outlook: Sunday 31 March and Friday 5 April. Experience has shown that we can’t yet count on this rain materialising. The timing of the next significant rain event remains central to when we can recommend easing the present water use restrictions.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Low demand helps to preserve our water reserves longer.

Tuesday’s water supply came from:
Rivers: 84ML
Hutt aquifer: 40ML
Storage: decreased by 2ML (within the Regional Council’s distribution network reservoirs)
Storage in Lake 2 remains 100% full

News from Greater Wellington Regional Council – March 26
Daily target water use (maximum) = 130 million litres (ML)
Monday’s water use = 128ML
Change from Sunday = lower by 2ML

Water use was just under the target for maximum daily use yesterday. We thank all water users for their continuing efforts to conserve water.

River flow rates remain well below long-term March averages. River-flow recession rates indicate that without further rainfall we could be back to low pre-rain flows for the Hutt River next week, while supply from the Wainuiomata and Orongorongo rivers could return to pre-rain levels in 10 or so days time.

The timing of the next significant rain event is central to when we can recommend easing the present water use restrictions. At present, the weather outlook for the next ten days indicates one day of rain on 31 March. However, this is only one day and experience has shown we can’t yet count on this materialising.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Lower demand helps to preserve our water reserves longer.

Yesterday’s water supply came from:
Rivers: 89ML
Hutt aquifer: 38ML
Storage: increased by 1ML (within the Regional Council’s distribution network reservoirs)
Storage in Lake 2 remains 100% full

News from Greater Wellington Regional Council – May 24
Daily target water use (maximum) = 130 million litres (ML)
Sunday’s water use = 130ML
Change from Saturday = higher by 3ML

Water use equalled the target for maximum daily use on Sunday. We thank all water users for their continuing efforts to conserve water.

River flow rates remain well below long-term March averages. River-flow recession rates indicate that without further rainfall we could be back to low pre-rain flows for the Hutt River in seven days time, while supply from the Wainuiomata and Orongorongo rivers could return to pre-rain levels in 10 days time.

The timing of the next significant rain event is central to when we can recommend easing the present water use restrictions. At present, the weather outlook indicates rain on 1 and 2 April. However, experience has shown that we cannot yet count on this rain materialising.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Lower demand helps to preserve our water reserves longer.

Sunday’s water supply came from:
Rivers: 81ML
Hutt aquifer: 44ML
Storage: decreased by 5ML (within the Regional Council’s distribution network reservoirs)
Storage in Lake 2 remains 100% full

The outdoor water use ban remains active.

News from Greater Wellington Regional Council – March 23
Water use on Saturday was again below the target for maximum daily use. We thank all water users for their continuing efforts to conserve water. But river flow rates remain below long-term March averages and continue to drop.

Daily target water use (maximum) = 130 million litres (ML)
Saturday’s water use = 127ML
Change from Friday = higher by 2ML

The 14-day weather outlook continues to indicate a chance of several days of rain, now from 30 March. However, experience has shown that we can’t yet count on this rain materialising.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Lower demand helps to preserve our water reserves longer.

Saturday’s water supply came from:
Rivers: 82ML
Hutt aquifer: 46ML
Storage: increased by 6ML (within the Regional Council’s distribution network reservoirs)

Storage in Lake 2 remains 100% full

The outdoor water use ban remains active.

News from Greater Wellington Regional Council – March 21
Water use dropped back below the target maximum daily water use yesterday. But river flow rates are below long-term March averages and continue to drop.

Daily target water use (maximum) = 130 million litres (ML)
Friday’s water use = 125ML
Change from Thursday = lower by 6ML

The 14-day weather outlook now indicates a chance of several days of rain from 1 April. However, experience has shown that we can’t yet count on this rain materialising.

We need to maintain the level of water use below 130ML per day at least until the next major rainfall. Lower demand helps to preserve our water reserves longer.

Friday’s water supply came from:

Rivers: 89ML
Hutt aquifer: 38ML
Storage: increased by 2ML (within the Regional Council’s distribution network reservoirs)

Storage in Lake 2 remains 100% full

We remain uncertain how rapidly river flows will return to pre-rain levels and will continue to monitor this critical variable. We need to keep demand low – the outdoor water use ban remains active.
