Tamworth Waste Water Scheme

Building Tamworth’s Environmental Future

Team Irrigation spearheaded the construction of the Tamworth Waste Water Scheme,which included:

• 13 new poly-lined Zimmatic by Lindsay centre pivots
• A fully integrated Watertronics pumps station, including five 215 horsepower (160kw) centrifugal pumps
• FieldNET pivot and pump wireless control system

With an expected population growth in excess of 50,000 Tamworth City Council needed to decommission two waste treatment plants in town and relocate them to the new Westdale site near Tamworth Airport. EPA licensing regulations also required Council to stop releasing treated sewage into the Peel River, thus an entire new effluent facility needed to be designed.

Following the success of Dubbo City Councils Greengrove Effluent Irrigation Facility where 100 percent of the city’s treated sewage is now kept out of the nearby Macquarie River, Tamworth City Council called for designs and quotes to make this project a success for their city.

TEAM Irrigation subcontracted to REALM Agribusiness to design & construct the irrigation scheme for the treated effluent. The irrigation project encompasses the erection of 13 poly lined centre pivots with a maximum output flow of 54 megalitres per day, irrigating 640 hectares. A further 12.5kms of poly pipe ranging in size from 200 to 400mm layed and polywelded every 20m.

The irrigated crops will supply feed for contracts and the Willowlynn dairy owned and operated by REALM Agribusiness.

TEAM Irrigation will also install a Lindsay Watertronics pump station near the settlement ponds to the 13 pivots. This fully automated pump can pump varying flows from 40 to 736 litres per second. This pump will be the first of its kind in Australia. The sheer size of the pump required assembly and pressure testing in the USA as there were no facilities available in Australia to deal with the pump size.

The Watertronics Pump Station  is equipped with a Variable Frequency Drive (specifically tunes pressure characteristics to each pump and combination of pumps in the system, ensuring near perfect pressure regulation) and Electronic Butterfly Valve ( Patented EBV complements VFD controls by pressure regulating each pump and provides 100% backup pressure regulation in the event of a VFD fault). The Watertronics control station and the VFD equipped pumps are extremely efficient. If you have only one pivot circle running, the station will pump only enough water and use only enough energy to supply one pivot. If two or more pivots are running, the Watertronics system will turn on another pump automatically.

To date, TEAM Irrigation has polywelded and layed  9kms of poly pipe, erected 7 centre pivots, and layed 13 pivot pads. Congratulations to Daniel Samson for polywelding this entire pipe project to date.
