Riverview Road, Scamander

TasWater is undertaking works in Riverview Road, Scamander to help address issues relating to the town's water quality.

The works will include construction of a 1.24 kilometre trunk main and a new inlet at the Riverview Road reservoir.

The works will be undertaken by Jemrok. They are scheduled to commence in mid-August and will take approximately eight weeks, weather permitting.

The new pipeline will be constructed along the western side of Riverview Road and will take approximately eight weeks, weather permitting.

Due to excavation works there will be some minor disruptions to access however Jemrok representatives will liaise with residents and doorknock before any excavation work is undertaken across driveways.

Other impacts may include dust and noise relating to the construction work and minor traffic delays for motorists using Riverview Road.

For safety reasons we ask that members of the public steer clear of any heavy machinery and follow any directions provided by our contractors.

Background

TasWater has been working for some time now to resolve water quality issues in Scamander with the aim of removing the existing Boil Water Alert.

In 2011/12 we designed and installed a roof on the Riverview Road reservoir to help protect water quality. We have also installed two booster pumps within the Scamander water supply network to turn over water in the reservoirs and have carried out extensive modelling on the network to help develop solutions to long-term issues. More recently we completed a major pre-treatment upgrade at the water treatment plant (WTP) in Upper Scamander Road.

The Riverview Road works will allow us to supply water from the Riverview Road reservoir while the WTP is operating, helping us to maintain a good chlorine residual within the system for disinfection. This is particularly important for providing a reliable service during peak tourism periods when water usage is at its highest and to maintain chlorine residual during winter when water usage in the system is at its lowest.

In order for the water to be safe for drinking without the need to boil it first, a chlorine residual is required to reduce the risk of recontamination. Specifically, a chlorine residual is required to control the risk of microorganisms including Escherichia coli (E.coli) if they are present in the water. Chlorine residuals decay in water over time. Therefore once the water is treated and disinfected at the water treatment plant we need to supply it to customers before the chlorine decays, usually within a few days.

With the current system it takes too long to fill the reservoirs and too long to empty them and it is therefore difficult to maintain a chlorine residual. This is why we still need to maintain the Boil Water Alert. Once we have a dedicated pipeline to Riverview Road reservoir and a separate pipeline out of the reservoir we will be able to control the water age more effectively and take steps to have the Boil Water Alert lifted.

Where to from here?

Once the Riverview Road works are complete TasWater will undertake a comprehensive water quality testing program. The results from this program will form the basis of TasWater's submission to the Department of Health and Human Services (DHHS) for the Boil Water Alert to be lifted.

Our customers will be notified in writing when this happens.
