Aucklanders still using too much water

NZ Newswire logoNZ Newswire 14/03/2017

Aucklanders' water consumption is still too high, despite reducing consumption slightly.

The city missed the daily water use target of less than 400 million litres for the second day in a row on Tuesday and is still hovering above levels needed to avoid a boil water notice.

"As the weather improves and the weekend's storms become a distant memory we run the risk of forgetting the need to reduce water use," Watercare chief executive officer Raveen Jaduram said.

Consumption dropped from the average 415 million litres, to 382 on Sunday, below the 400 million that was asked - but climbed back to 419 million on Monday.

The figures for Tuesday were slightly better, but still at 409 million litres.

Auckland's main water supply, Ardmore Water Treatment Plant, has been working at half its usual capacity since heavy rains caused flooding in the area last week and clogged it with debris.

If Auckland's use doesn't drop enough, the untreated water will have to be released into the system and would have to be boiled by residents.

Watercare has asked each resident to cut their use by 20 litres, or two bucketfuls, per day for the rest of March.

It would be some time before consumption could return to normal and residents had to keep going, it said.

"The reality is we are still dealing with 100 times more silt at our Ardmore treatment plant," Watercare said.

Auckland Council has switched off fountains and irrigation systems in parks, and petrol retailers Z and Caltex have closed their car washes.

TIPS TO SAVE WATER:

* Cut your shower time by two minutes to save round 16L

* Turn off the tap when brushing your teeth to save round 4L

* Only run your dishwasher and washing machine when full

* Use the half-flush on your toilet.
