Warrens Gully Pump Station

Located on the Bank of the Burdekin River, the Warren's Gullys Pump Station consists of two electrically driven submersible pumps. Each pump (170kW) is capable of delivering 940 litres of water per second or 70 megalitres per day through individual pipe rising mains for river level to top of the bank and into the Warrens Gully Diversion Channel.

Osborne Relift Station

Strategically located within the Warrens Gully Diversion system, the Osborne Relift Station consists of two electrically driven submersible pumps. Each pump is capable of delivering 180 and 240 litres of water per second or 15 and 20 megalitres per day respectively to Osborne area consisting of 7 artificial recharge pits and diversion area

Malaponte Relift Station

This pump station is currently not in use however the station consists of one electrically driven axial flow flood lift pump. This pump when used, has a pumping capacity of 850 litres per second or 70 megalitres per day to the collection chamber and Plain Road pipeline delivering reliifted water to the Central Diversion System.

Sand Dams

The Warrens Gully Sand Dam is located approximately 150 metres downstream of the pump station water intake infrastructure. The purpose of the sand dam is to create a pumping pond to the river pump station, the idea being to maintain a constant pool of water and more importantly, the surface of the pool to be kept at operating level regardless of the variations in the river flow. Water excess to the pumping pool level bypasses the sand dam and continues down the river. Sand dams are constructed from river bed sands by hydraulic track excavators and during high river outflow will naturally dissolve to river bed level. Reconstruction of sand dams occurs after high level flows. Sand dams are not water tight and seepage through the sand wall will at times causes washouts when average flow of the river is exceeded.

The Alma Dam is a constructed earth wall situated at the bottom end of Alma Diversion its primary purpose is to create pondage for water recharge of the regional aquifer between Inkerman Hill and Alma Hill.

River bed sand dams are essential to the operational efficiency of the pumps.

Recharge Pits

There are nine recharge pits on the Warrens Gully scheme, subject to suitable water provides artificial replenishment, with individual maximum capacity of 20 megalitres when operational. There are ten natural lagoons/pondages on the scheme connected by open earth channels, varying in capacity from 7 megalitres to 350 megalitres they provide natural groundwater replenishment.

Diversion Areas

There are five diversion areas within the Warrens Gully Scheme, made of natural watercourses and lagoons inter-connected by pipes or man-made open earth channels with purpose of surface water distribution and groundwater replenishment. These diversion areas are commonly known as:

◘ Osborne Recharge Pit Area

◘ Lakes Diversion Channel

◘ Munros Diversion Channel

◘ Alma Diversion Channel

◘ Goose Lagoon Diversion Channel

◘ Sandy Creek Diversion Channel

These diversion channels supply 89 surface water permits supplying a total base volume of 16,108 megalitres to 4,027 hectares. Sandy Creek Diversion channel provides water service from Alma to Down River diversion channels.
