The Tamworth City wastewater reuse project was 14 years in the making and designed to secure the city’s effluent disposal for up to 40 years. With a full arsenal of Lindsay products, including pivots, pumps and remote telemetry. TEAM Irrigation, Lindsay’s local Zimmatic dealer in Dubbo, NSW, Australia, spearheaded the project, which took approximately 12 months to complete. With the city’s population expected to grow to nearly 50,000 by 2020, the Tamworth, Australia, City Council decided to decommission and relocate its two existing wastewater treatment plants to the outskirts of town. Today, instead of being dumped into the nearby Peel River, the town’s treated wastewater is pumped through Zimmatic® pivots and used to irrigate local crops, which then are sold to local dairies and feedlots. “We were proud to be involved in the project from conception,” says Craig Chandler, managing director of TEAM Irrigation. “This multi-million-dollar project was unique in that it involved numerous Lindsay products, including the pivots, pumps and all of the controls.” It was a team effort involving Realm Agribusiness, which served as the principal contractor on the project, and manages the irrigation system and farming operation. ZIMMATIC PIVOTS The town’s treated water is pumped through 13 new Zimmatic center pivots, ranging in length from 1,772 feet (540 m) to 778 feet (237 m). They are designed to apply .36 inches (9 mm) of water over the fields in a 24-hour period. Watertronics Pump Station Key to the innovative wastewater treatment project is a fully-integrated Lindsay Watertronics® pump station that is used to move the effluent from holding ponds through the Zimmatic pivots and ultimately onto 1,581 acres (640 ha) of grain and alfalfa crops. According to John Atkinson, Watertronics agricultural sales manager, the Tamworth pumping station consists of five 215 horsepower (160 kw) centrifugal pumps, each capable of pumping 2,400 gallons (9,085 liters) per minute. The pumps are equipped with variable frequency drives (VFDs) to specifically tune pressure and flow characteristics to each pump, ensuring near perfect pressure regulation. The Tamworth wastewater treatment system allows for a maximum daily effluent discharge of 14.2 million gallons (54 ML). It irrigates 1,581 acres (640 ha) of local crops such as grain and alfalfa, which are then sold locally. FULLY TESTED AND READY TO PUMP Watertronics® offers integrated pump systems and controls that help maintain consistent, surge-free water delivery for optimum pressure regulation.
