Goulburn Valley Water (GVW) is continuing its odour reduction program with work on an aging sewer main in Shepparton, Victoria, expected to start at the end of 2018.
Goulburn Valley Water (GVW) deals with odour issues resulting from aging and deteriorating sewerage infrastructure.
Through its asset management program, GVW has identified that the aging sewer main running along Wyndham Street, between Macintosh Street and Sobroan Street, need to be replaced.
GVW is currently taking actions to reduce the pressure on the main to ensure it does not further degrade before the works start.
To mitigate additional damage to the infrastructure, GVW will reconfigure the system to utilise an adjacent gravity sewer main for the majority of the flows from the Sobroan/Wyndham Street corner to the water treatment plant on Welsford Street.
GMV said as the gravity mains flow slower, there is an increased chance of sewer odour in the immediate area during the next 12 months.
In the past five years, GVW has spent more than $1.8 million on odour reduction programs across the region.
This has included trialling, both short and long-term solutions including the use of deodorising sprays, replacement of sewer mains, new storage tanks and towers, and upgraded pump stations.
Improvements in technology and GVW’s odour management program have resulted in a reduction in odour complaints.
In 2016, GVW received 28 odour related complaints across the region compared to 95 complaints in 2009.
