Water use soars as Perth heats up

1points Posted 613 days ago by mattdidcoe

As Perth sweltered through its fifth-hottest November day on record yesterday, rocketing water use has prompted the Water Corporation to warn it would crack down on anyone flouting water restrictions

Am I right in understanding that bore users also have to comply with water restrictions?

I duno, I was watering the lawn last night with tap water, our landlord will kick our arses if that lawn dies, I don’t give a **** about restrictions.

If they want people to think about their use, then put the price of water up. The excess at our house is about $80 a year for 3 people… dirt cheap.

Agreed. Had our rental inspection yesterday and received similar kick-up-the-bottom from the agent re the gardens. I think there has to be a middle ground that can be struck.

Yes us bore owners do have to comply with the water restrictions this year, except we get three watering days a week instead of two.

@Runamuk - How expensive do we make excess water before it will make a difference to people’s usage? $10,000 a year is dirt cheap for some people, and $80 a year is a small fortune for others. If you carry that approach to its logical conclusion then the mega rich could end up using 90% of the water supply whilst the rest of us divide up the remaining 10%.

Dave, the drought problems of the Murray Darling are an example of what happens when water is under priced. There should be a dual approach to water management, using pricing and restrictions, to ensure long term sustainability.

Bores should be banned in the metropolitan area. They are pulling all the ground water from catchment areas, including lakes and swamp land. These valuable ecosystems ensure diversity of bird life and native animals.

The main point I was trying to make is that for a lot of people, increasing the pricing is not going to make any difference to their usage.

Bores only have a negative impact on the environment in certain metropolitan (or regional) areas. In many cases they have a positive environmental impact. Suburban development reduces the amount of tree cover, resulting in upward movements of the water table and salination of the land. Sinking bores can reverse this.

Rather than banning bores, we should be banning European-style gardens and lawns from residential properties.

I agree with your sentiments on lawns and gardens, although it might take a while to convince the people of Perth!

The topography of the Perth groundwater aquifer means that the water is naturally of very low salinity. So a rising rising water table would not result in problems with salination. This is not true for the wheat belt, where I agree with your comment about trees being an important component of the ecosystem.

My observation is that many of the wetlands around Perth are dry or almost dry by the end of summer. The rainfall over Perth has not changed over the past 30 years, so the only explanation is bore usage.
