Water Update - March 2018

Coonabarabran Water Report

19 March 2018

For the week commencing Monday, 19 March 2018, the water level at Timor Dam was 27.2% of dam capacity. The water level is at the lowest level in recorded history. With minor inflows in recent months, the water level in the dam has steadily depleted.

It is expected that outflow from Timor Dam will cease to operate under gravity when the level reaches 20% of capacity. A pump out system has been installed to access the water when outflow by gravity is no longer available.

The town water supply in Coonabarabran is currently being supplemented by four (4) bores and from a river well in Namoi Street. Three (3) of these bores pump to the river well where water from the bores and the river is pumped to the Water Treatment Plant along Timor Road. Long term supply from the river well is not expected to meet demand and may not be sustainable if flow in the river ceases.

As an emergency measure, a program of bore construction has commenced along Timor Road. To date seven (7) sites have been identified as potential bore sites. Test drilling has occurred at six (6) of these sites. Assessing the potential of each bore site includes logging of intercepted aquifers as well as water quantity and quality and potential supply rates. To date draw down testing has occurred at the sites in the grounds of the Water Treatment Plant and Nandi Park. Before any of the bores are approved for production it will be necessary to prepare a hydrogeological study of each site and advertise the proposal for 28 days.

Further to these measures, the provision of infrastructure for raw water delivery at the Water Treatment Plant has been identified by the Department of Industry – Water as an important area of work to be planned and progressed. This infrastructure will allow water that is transported from external supplies to be readily received into the Coonabarabran water supply system. Council has been successful in an application for funding for the development of this infrastructure should it be required.

Water consumers in Coonabarabran have generally responded to the onset of low water supplies by reducing consumption. The average daily production of water at the Coonabarabran Water Treatment Plant has trended downwards over recent weeks.

Currently the average daily water production is around 0.8Ml per day. No targets have been formally set for average daily consumption, however it is desirable to lower the current consumption rate to an average daily consumption of around 0.45Ml per day.

The average daily consumption (Ml per day) recorded over seven (7) days, by week, for the last four (4) weeks is:

Residents are asked to limit their water usage wherever possible. Your efforts to minimise use at this time is greatly appreciated.

Residents are reminded that failure to comply with restrictions may result in a fine or disconnection of your service. Active patrolling of streets in Coonabarabran, to check compliance with water restrictions, is being undertaken each day.

Coonabarabran Water Report

12 March 2018
For the week commencing Monday, 12 March 2018, the water level at Timor Dam was 27.9% of dam capacity.

Due to ongoing dry conditions, dropping water supplies and high usage, Level 6 water restrictions are now in place. These restrictions will be in place until further notice.

Although the average daily consumption over the last seven (7) days has dropped, the average daily usage is still higher than it needs to be.

In the week commencing Monday, 12 March 2018, the average daily consumption was 0.9ml/day. This is a reduction in average daily consumption of 0.1ml/day.

The average daily consumption recorded over seven (7) days, by week for the last four (4) weeks is:

Council advises that the average daily consumption will need to continue to reduce. The aim for average daily consumption is 0.4ml per day.

To help achieve this, residents are asked to limit their water usage wherever possible.

Your efforts to minimise use at this time is greatly appreciated.

Residents are reminded that failure to comply with restrictions may result in a fine or disconnection of your service. Active patrolling of streets in Coonabarabran, to check compliance with water restrictions, is being undertaken each day.

 

 

Coonabarabran Water Update

6 Mar 2018

Preparation of alternative water sources for the Coonabarabran water supply is continuing with investigations into a number of new bores in the area.

“While Coonabarabran had some good rainfall last week this has, unfortunately, only had a minor positive effect on the Timor Dam” said Warrumbungle Shire Mayor, Councillor Peter Shinton.

“Council is continuing to progress the investigation of a number of bore sites in and around Coonabarabran.”

Level 6 Water Restrictions for Residents of Coonabarabran

6 Mar 2018

Level 6 water restrictions will come into effect in Coonabarabran from midnight on Monday, 5 March 2018.

Warrumbungle Shire Council has had to make this decision due to ongoing dry conditions, dropping water supplies and high usage levels.

As of Monday, 5 March 2018, the water level at Timor Dam was 28.1% of dam capacity. The current dam level is the lowest level that it has been since its construction in 1964 and is lower than the worst level recorded during the 2002 – 2010 Millennium Drought.

Residents are encouraged to limit their water usage and preserve water wherever possible.
