Water & Sewer Treatment Schemes
Condobolin Sewerage Scheme
Raw sewage is delivered to Condobolin Sewage Treatment Plant via gravity and also 14 sewage pumping stations. Condobolin Sewage Treatment Plant consists of two separate treatment systems:
- A 2000 EP double unit biological trickling filter plant, which treats two thirds of the sewage collected at the STP; and
- A 2000 EP pasveer channel treatment plant, which treats one third of the sewage collected at the STP.
Lake Cargelligo Sewerage Scheme
Raw sewage is delivered to Lake Cargelligo Sewage Treatment Plant via gravity and also three sewage pumping stations:
- Lake Street Pumping Station
- Loughnan Street Pumping Station
- Uabba Street Pumping Station
Tottenham Sewerage Scheme
Raw sewage is delivered to Tottenham Sewage Treatment Plant via gravity and via Tottenham Caravan Park Sewage Pumping Station. The Plant is a 1000 EP pasveer channel plant.Condobolin Water Supply Scheme
Condobolin draws its water from both surface and ground sources.
Surface water extraction takes place at the Goobang Creek Weirpool, upstream of the Goobang Creek Weir, located on the eastern fringe of Condobolin township. The pumping infrastructure consists of two centrifugal pumps, each capable of delivering 45.5 Litres/second to the water filtration plant. The township has an annual surface water allocation of 1500 Megalitres (Licence No. 70AL600019).
Ground water is extracted from a bore which is located on Mission Road, approximately 2.4 km to the South East of the water treatment plant. The bore is capable of supplying up to 28 L/s to the water filtration plant. The township has an annual ground water allocation of 800 ML (Licence No. 70BL229185). The bore is licensed as a supplemental/emergency bore and is not intended to supply the township's requirements on its own.
Ground water from the bore is saline and is needs to be blended with surface water to comply with ADWG requirements (one part ground water to two parts surface water). Investigation is currently underway to compare the options of a reverse-osmosis treatment system for this bore water or taking water from another bore 20km away.
Extracted surface and ground water are treated at the Condobolin Water Treatment Plant, which utilises coagulation, flocculation, dual-media filtration and chlorination to purify the raw water. Powdered Activated Carbon is available for treating the raw water in times of high algae loadings. Fluoride is added to the water prior to pumping to the township’s three reservoirs, which have a combined storage capacity of 10.35 ML. Water gravitates from the reservoirs throughout the township’s reticulation to consumers’ services.
Council supplies bulk treated water to Willow Bend village via the Condobolin reticulation system.
Lake Cargelligo Water Supply Scheme
The Lake Cargelligo Water Supply Scheme supplies water to Lake Cargelligo, Tullibigeal, Kikoira, Murrin Bridge and to rural consumers connected to the Lake Cargelligo-Tullibigeal and Kikoira rural trunk pipeline. Lake Cargelligo draws its water from surface water sources and three new bores at Merri Abba.
Surface water extraction takes place from the Lake Cargelligo storage, with the raw water intake, wet well and pumps located on the western foreshore of Lake Cargelligo. The pumping infrastructure consists of two submersible pumps in a duty/standby configuration, each capable of delivering 64.5 L/s to the water filtration plant. The scheme has an annual surface water allocation of 699 ML (Licence No. 70AL600022) for town water supply and a high security stock & domestic annual allocation of 160 ML (Licence No. 70AL601865).
A total of three bores have been established at Merri Abba and the construction of a transfer pipeline and associated reservoirs, pumping stations and high voltage electricity supply was completed in March 2013. Both the NSW State Government and the Australian Federal Government have provided considerable subsidy funding to make this project feasible.
Extracted surface and ground water are treated at the Lake Cargelligo Water Treatment Plant, which utilises dissolved air floatation, UF membrane media filtration, Granulated Activated Carbon filtration and chlorination to purify the raw water. An iron and manganese treatment system is also incorporated at the plant. The treated water is pumped to the township’s reservoir which has a usable storage capacity of 3 ML. Water gravitates from the reservoir throughout the township’s reticulation to consumers’ services.
The Tullibigeal and Kikoira/ Gibsonvale rural water supply systems operate by pumping water from the Lake Cargelligo reservoir to the 16 Mile Balance Tank (approximately 250 kL capacity) through a 25.6 kilometre pipeline. Water is then pumped from the 16 Mile Balance Tank to the Tullibigeal township’s reservoirs through a 20.7 kilometre pipeline and to Kikoira through a 25.2 km pipeline.
Tullibigeal Township has 4 reservoirs which have a combined storage capacity of 0.6 ML. Water gravitates from the reservoirs throughout the township’s reticulation to consumers’ services.
Bulk potable water is supplied to Murrin Bridge village at a connection to the Lake Cargelligo reticulation at the ‘old filtration plant’. Water gravitates to the Murrin Bridge reservoir (150 kL) via a pipeline owned and managed by the Murrin Bridge Local Aboriginal Land Council, Although Council is currently working with NOW and negotiating to take on the maintenance of this water system.
Tottenham Water Supply Scheme
The Tottenham Water Supply Scheme supplies water to Tottenham and Albert. The scheme has two sources of raw water; the B-section Pipeline that runs from Forbes via Parkes Shire to Tottenham and the local ground storage tank known as ‘Leg O Mutton’ Dam. The B-Section Pipeline is the primary water source for the Tottenham Water Supply Scheme.
Forbes Shire Council treats and supplies all water supplied to the B-Section Pipeline. Parkes Shire Council pumps water from the Tullamore Reservoirs to the Albert Reservoir. The Albert Reservoir has a storage capacity of approximately 250 kL. Water then gravitates to the Albert township reticulation and to the Tottenham Reservoir. The Tottenham reservoir has a storage capacity of 700 kL. Water gravitates from the Tottenham reservoir throughout the township’s reticulation to consumers’ services.
Lachlan Shire Council becomes responsible for the delivery of water, maintenance and repair of the B-Section Pipeline once it crosses the LGA boundary between Parkes Shire and Lachlan Shire to Tottenham. The pipeline length is approximately 45.29 kilometres.
An investigation conducted in 1986 and confirmed by NSW Public Works in 1991 concluded that the pipeline is only able to supply 55% of the peak summer demand for the scheme. Demand requirements have remained relatively unchanged between 1991 and the present.
Surface water extraction takes place from the Leg O Mutton Dam, which is located on the southern side of Tottenham village. The dam captures local stormwater runoff and is used to supply additional capacity/supplemental supply to the township in summer and provides an emergency backup supply if a failure of the B-Section Pipeline occurs. The design storage capacity of the dam is 45 ML. The pumping infrastructure consists of one submersible pump capable of delivering 14.5 L/s to the water filtration plant.
Extracted surface water from the Leg O Mutton Dam is treated at the Tottenham Water Treatment Plant, which utilises coagulation, lagoon sedimentation, pressurised rapid sand media filtration and chlorination to purify the raw water. The treated water is pumped to the township’s reservoir and then gravitates from the reservoir throughout the township’s reticulation to consumers’ services.
Burcher Water Supply
Burcher draws its water from a surface water source. Surface water extraction takes place from a storage dam located west of the village. The dam captures local stormwater runoff and has a storage capacity of 30 ML. The pumping infrastructure consists of one centrifugal pump capable of delivering 2.5 L/s (approximately 180 kL per day) directly into the village reticulation. A balancing storage reservoir of 60 kL provides water when the pump is not operating. The supplied water is not treated.
Fifield Water Supply
Fifield draws its water from two surface water sources. Surface water extraction takes place from two storage dams located south east of the village. These dams capture local stormwater runoff and have capacities of 30 ML (larger “Main Tank” Dam) and 12 ML (smaller “Swimming Hole” Dam).
The pumping infrastructure consists of one centrifugal pump capable of delivering 2.5 L/s directly into the village reticulation, which is approximately 180 kL per day at each dam. The Swimming Hole Dam pump supplies water to the town reticulation. The Main Tank Dam pump is operated manually and is used to top-up the Swimming Hole Dam when storage levels fall below 50%. A balancing storage reservoir of 60 kL provides water when the duty pump is not operating. The supplied water is not treated.
