Times of drought

All water utilities across Australia struggle with increased population growth and extended periods of low rainfall. The Millennium Drought has caused challenges for all Australian urban water supplies. The levels in major east coast storages have diminished to the lowest levels in decades.

During times of drought, local councils work with water infrastructure authorities and water utilities services to action water-efficiency measures and support to residents and businesses to capture and store rainwater and greywater. Play your part in reducing leaks by maintaining your property’s water service.

Water is precious, especially during current times of drought and as such we cannot afford water egress and seepage from water retaining structures such as holding tanks, dams, catchments, reservoirs and water infrastructure pipelines. Water restriction levels are likely to increase in the beginning of 2020 and fines may apply if water leaks are left untreated. If you don’t respond when authorities ask you to fix a leak, you may be subject to fines under the higher water restriction levels.

It is best to act quickly as most leaks tend to get worse over time.


Level 3 Restrictions for Sydney

Upon the commencement of the Level 2 water restrictions in December 2019, Minister for Water, Property and Housing, Melinda Pavey announced that Level 3 water restrictions should be expected early in the year of 2020. (Ref.)

Water restrictions are looming for South-East Queensland

Dam levels dropped below 60 per cent capacity in November – the lowest level since the Millennium Drought broke in 2008 – while the region’s biggest drinking water source, Wivenhoe Dam, fell under 48 per cent. However, Seqwater will not look at water restrictions until dam levels drop to the combined 50per cent capacity.

Queensland experienced the driest November on record as “Not a single major location in Queensland recorded at least average rainfall!

One of the significant culprits to our unusual rainfall patterns has been the unusual sea surface temperature patterns due to the following:

🔹 No moisture coming from the Indian Ocean

🔹 Limited moisture coming from the Pacific Ocean

🔹 Limited moisture coming from the Indonesia/Equatorial region (monsoon trough further north than it should be)

All of this has culminated into an incredibly dry period for not just November, but much of winter and spring (on top of already dry periods and years prior to this). (Ref.)
