Our wastewater systems
AlburyCity has three wastewater systems:
- The urban area of Albury City
- Hume Weir Village and
- Lara Lakes at Table Top
Splitters Creek, the residences around the Hawkesview/Knoble Roads area of Wirlinga, the rural residences on the outskirts of the urban area and the farmland residences are not connected to any sewerage reticulation system. These have their own on-site treatment systems which are monitored by Council’s ‘Compliance Section’.
Albury City Urban system
The Albury City Urban system consists of:
- Two treatment plants (Waterview at Splitters Creek and Kremur Street in West Albury)
- Six major pumping stations
- More than 50 minor pumping stations
- Greater than 550km of sewer mains that vary in diameter from 150mm to 750mm.
Part of the reticulation system also includes 8,250 access manholes and 196 vent pipes.
Sewage generated from the various customers gravitates into the reticulation system and eventually flows to the pump stations which in-turn pump it to the treatment plants. Depending where you live, the sewage generated from your property may go through five pump stations before it reaches the treatment plants.
The two treatment plants treat on average 10.5 ML per day or the equivalent of four Olympic-sized swimming pools (a megalitre is one million litres).
As part of the operations of the wastewater system we dose an odour neutraliser at seven pump stations throughout the City to control odour. For emergency purposes, particularly electricity blackouts, we have diesel-powered back-up generators. Council also has two mobile pump stations that can be taken and used at any one of the minor pump stations should these stations have a blackout or there is a major pump malfunction.
Kremur Street Treatment Plant
The Kremur Street treatment plant was constructed in 1916 and has been upgraded or modified a number of times, the last being in the late-1980s. It is a Biological Nutrient Removal (BNR) plant with a treatment capacity of 10 ML per day. Disinfection at this plant occurs via the two large maturation ponds which form part of Horseshoe Lagoon (in West Albury). The treated effluent is pumped to Waterview Treatment Plant where it mixes with the treated effluent from the Waterview Treatment Plant.
Waterview Treatment Plant
The Waterview Treatment Plant was constructed in 2000 and is also a BNR plant. It has a treatment capacity of 8 ML per day and incorporates tertiary treatment using sand filtration and disinfection.
Both treatment plants have chemical back-up (using Alum) for phosphorus removal. A by-product of the treatment process is biosolids (sludge).
An approval condition for the construction of the Waterview Treatment Plant was that no treated effluent was to discharge back into the Murray River. Therefore, all the treated effluent produced by both plants become part of a reclaimed water re-use system, and this is discharged to the Wonga Wetlands in the cooler months and timber plantations and irrigated pastures during the warmer months.
Hume Weir Village system
This system only services the Hume Weir Resort, the Hume Weir Caravan Park and the Hume Dam workshop and Eraring electricity power station. It was constructed in 1977 and has a capacity of 100 KL/day. It is an activated sludge plant utilising a Pasveer channel. Disinfection is achieved using maturation ponds and the treated effluent is discharged to the Murray River approximately 300 metres downstream of the Hume Dam wall.
The sludge produced as part of the treatment process is collected in a sludge lagoon which is allowed to dry out and the dried sludge is collected and disposed of.
Lara Lakes system
This system only services approximately 35 residences surrounding Lara Lakes in Table Top. It was constructed in 1989 and has a capacity of 100 KL/day. Its treatment process uses two facultative lagoons and the treated effluent is irrigated onto 1.5 hectares of adjacent woodlots.
