Evapotranspiration from the irrigation area has been reduced also during the lengthy wet periods and the operation has resulted in return of water to the collection system.
Analysis of this obviously contaminated water coming from the tip face has been carried out. Officers from the Chemical Control Unit of Environment Protection Section have monitored the treatment of this water before it was of a suitable standard for release. The treatment has consisted of chemical removal of sulphides and flocculation to precipitate other chemicals.
After treatment of these Teachers ponds the water has been (and continues to be) discharged to the pollution control ponds.
As a result of these extreme rainfalls it is being considered necessary for the collection channels to be modified and additional interceptor ponds to be constructed so that the Teachers can be kept separate from other water running off the site.
The water management procedures for the Mugga tip are comprehensive and as a consequence there is no detrimental impact on the Jerrabomberra wetlands.
Future of Mugga Landfill Site
The most recent study of landfill requirements indicated that the Mugga Lane tip has about another seven years of operational life. Development works are being undertaken at the tip which will enable it to function for that period.
