Jacks to Chilean capital Santiago

Jacks to Chilean capital Santiago

Landustrie Rwzi Santiago Chile 2 800x321

For the largest sewage treatment plant in Latin America, La Farfana in the Chilean capital Santiago, Landustrie is going to build five new jacks supply. The augers will be placed in the intake pumping station, where some 6-7 hundred thousand m3 of wastewater per day will be pumped into the treatment process.

Before the contract was awarded, a large package of tender requirements had to be met. When awarding the contract, not only the lowest price was eventually considered, but also quality aspects and references. Quality in particular was one of the spearheads, especially since the existing steel augers were already showing signs of fracture after only a few years of operation. Landustrie uses the Finite Element Method in its screw jack design. With this calculation programme, the acting forces can be mapped out under all circumstances and the most ideal jacking design can be determined. All five screw pumps, with a diameter of 3.7 metres and a length of about 21 metres, will be delivered and assembled with drive and electric controls. Landustrie is also responsible for the structural modifications to the pumping station.

The new jacks will be exchanged in several stages. The entire project should be completed by the end of 2022.

Meanwhile, LANDY hydropower jacks have been installed in the existing weir, in the River Ill near Erstein. A total of six augers, each with a diameter of 2.5 metres and a weight of 7 tonnes, will produce about one million kWh per year. This amount of renewable energy is good for about 250 households.

New controls for 650 pumping stations

With the demise of Cicruit Switched Data (CSD) dial-up technology, Municipality of Koggenland was forced to find another communication solution for its 650-plus sewer pumping stations. To this end, the control systems had to be converted to be ready for a future focused on the 4G network.

To treat industrial wastewater, three Landy augers have been shipped to Vancouver, Canada. After arriving at the port, the augers will continue by road to British Columbia. The augers are over 2 metres in diameter and up to 14.5 metres long.

Lightweight Wetterfretter

Landustrie's renowned dirt cutting Wetterfretter pumps are now also available in a compact and lightweight version. By adapting the pump and motor housing, a compact pump has been realised with a weight of only 35 kg. In case of inspection or maintenance, the pump can easily be lifted by hand. Especially at mini pumping stations where no lifting facility is available, this pump offers a solution.
