DELTA keeps drippers clean and grapes growingPosted on September 20, 2017
Grape grower Dino Sigismondi, who with wife Veronica grows grapes on about 250 hectares of land split between Lyrup and New Residence districts on the Murray River, reckons it was a ‘very good day’ when he first installed the DELTA technology on his drip irrigation system.
Since then Dino, from SA’s productive Riverland, has added another five DELTA units to his vineyard operation after the technology proved resoundingly successful in banishing algae from irrigation systems.
“The units keep the dripper lines very clean,” Dino says. “Since installing them I haven’t had to chlorinate the drippers and I used to do that twice a year.
We’ve now got a clean irrigation system, a more efficient system, the pressure is higher and the vines are a lot healthier too. Since we installed the first DELTA we haven’t looked back.
Grape grower Louis Curtis also says his irrigation system is cleaner and more efficient since he installed three DELTA water conditioners to treat river water supply.
Louis, who runs second-generation Curtis Vineyards at Pike River in SA, says he turned to DELTA technology after becoming frustrated with having to clean filter systems at his pump stations so regularly.
“Over time I noticed the automatic flush filters weren’t flushing as often and that tells me the system’s running much cleaner,” he says. “I pulled the filters down a few months later and they were cleaner. It has cut maintenance of the filters at the pump station by at least 30 per cent.”
Cut maintenance, improve performance
Dino and Louis are among a growing number of grape, fruit and vegetable growers and large-scale irrigators in South Australia’s productive Riverland turning to the DELTA technology of to drastically cut maintenance and improve performance in their vital irrigation systems.
Renmark-based irrigation agronomist Trevor Sluggett says growers are so pleased with the results after installing the DELTA water treatment system, they’ve returned for more units.
Trevor says an increasing number of growers are recognising the potential DELTA can deliver.
Interest in the DELTA product is increasing as growers hunt for ways to boost irrigation system efficiency, lower water use and improve yields.
He says some growers plagued with clogged dripper irrigation systems due to algae and other biological activity have reported substantial maintenance savings after installing a DELTA unit.
“All these systems in the lower part of the Murray River need a stringent maintenance program or the performance of these systems declines over time.
“Growers pumping water from backwaters off the main river stream have been the keenest to install the technology as they find their water is harder to filter and drip systems block up very quickly. These growers have had amazing results, such that even growers pumping better quality water are showing interest.”
