Water restrictions FAQ

Water restrictions FAQ

We answer some of your frequently asked questions about water restrictions.

What is the outlook for Summer 2019-20?

Last summer was another record breaking season for high temperatures and low rainfall. The region’s water storages and river flows held up well, but if the coming winter and spring are dry, it is likely that parts of our service area may need water saving measures implemented in summer 2019-20.

Are we already on water restrictions?

At this time there are no ‘Stage Restrictions’ implemented on any town within our service region. However, all of Victoria has permanent water saving rules in place. These rules are a set of common-sense measures to reduce demand and make sure we use water efficiently.

You can view the rules here.

Are we likely to have restrictions this summer?

The forecasts are pointing to a dry winter and spring which means it is likely that some towns within our region may need restrictions implemented this summer.

Over the coming months we will assess water usage, storage levels and river flows along with rainfall and temperature outlooks from the Bureau of Meteorology before making any decision on when and where restrictions are put in place.

How do we decide which towns will be on water restrictions?

We monitor water usage, storage levels and river flows which are then combined with river flow, rainfall and temperature outlooks from the Bureau of Meteorology. This allows us to forecast if towns and cities in our region need to be placed on water restrictions.

Conditions are continually monitored and our ‘Water Outlooks’ for each will be issued on 1 December and then updated regularly over summer.

Do we need water restrictions now?

Some people may have an expectation about bringing in restrictions now, however during the cooler months, customers aren’t using much water. We refer to this as the base demand period and it represents a time where there is little restrictable demand. Water restrictions are not effective during this period.

Restrictions have the most benefit when they’re absolutely necessary as there is a risk that customers will get ‘fatigued’ about such measures before they are really needed.

Water levels in Lake Hume are low - should I be concerned?

Lake Hume is currently at 34% capacity. This level is not unusual for this time of year and reflects the dry summer we have had. Now that irrigation demand has reduced the Murray Darling Basin Authority will manage Lake Hume to maximise volumes in storage via natural inflows from the Murray and Mitta Mitta rivers. Should dry conditions continue, water transfers from Dartmouth to Hume will recommence to supplement natural inflows to Lake Hume.

Dartmouth Dam serves as a drought reserve and is currently at 62% of capacity – that’s enough water to refill Lake Hume to full supply capacity, even in the absence of any natural inflows.

How much water is used by North East Water customers on the Murray system?

The River Murray system operated by the Murray-Darling Basin Authority, consists of many storages and lochs to ensure that water can be stored and delivered to water holders across three states. Water is used for irrigation, environmental and urban water supplies. Urban water use makes up approximately 7% of all water use on the Murray System.

North East Water holds approximately 1% of water available on the Murray system which is used to supply half of our customer base. Our other customers receive their water from local waterways, storages and groundwater.

How do water entitlements work for North East Water?

The Murray system operates on a seasonal water allocation model. The season runs from 1 July to 30 June each year. The Northern Victorian Resource Manager (NVRM) determines how much allocation is available. The level of allocation is based on how much water is available in the whole Victorian Murray system. For instance, despite Lake Hume being low at present, we have access to 100% of our water entitlement. This is because there is much more water stored elsewhere in the Murray-Darling Basin that we can access.

North East Water holds water entitlement that is far greater than annual customer demand. We hold this extra water to ensure that we can meet demand during dry years when reduced allocation is made available by the NVRM. We also have access to “carryover’ – this is unused water allocation that can be carried over into the following season. Carryover into 2019-20 will be maximised as we plan for ongoing dry conditions.

How does North East Water prepare for drought?

The last time restrictions were needed in north-east Victoria was in 2010. Over the past decade we have invested around $35 million in projects to improve the drought resilience of our region.

Projects include new efficient water treatment plants in Bright, Myrtleford, Whitfield and Eskdale as well as several new water pipe networks linking smaller towns to larger centres.

We also have a Drought Preparedness Plan that highlights our response for when a shortfall in water availability occurs. The Plan is tailored to each individual water supply system with trigger levels clearly indicating what actions are required and when. It is reviewed every five years or upon any supply system change. You can access the DPP here for more information.

What can I do to save water now?

We would urge people to save as much water as possible during this period so there’s less likelihood of restrictions in summer 2019-20.

Permanent Water Saving Rules are also in place across Victoria. The rules include using a trigger nozzle on your hose to water the garden or wash the car, only using watering systems between 6pm and 10am, and not hosing concrete paths or driveways.
