The primary raw water source for the Mataura Water Supply comes from the Pleura dam located approximately 5km east of the Mataura township. The dam has been located in this catchment since at least 1927 supplying the township of Mataura with water. The dam is located at 137 Cameron Road approximately 800m from the main road. Access to the dam is via a farm access track which is in reasonable condition.
Sediment removal and maintenance of the dam is necessary to ensure it continues to function as a source of water for the township of Mataura. Ensuring any potential impacts on both the surrounding environment and town water supply are appropriately managed will be critical to guarantee a successful outcome for this project.
To comply with the existing water permit consent condition maintaining a minimum flow of 5 litres/second over the dam wall, a temporary bypass pump/pipe will be required while the sediment removal process is being carried out. While the Council can use an alternative water source while this work is undertaken this is likely to cause taste and odour issues in the town water supply. Due to these taste and odour issues, it is preferred that the use of the alternative source is minimised or avoided completely if possible.
