The sewerage network in Nemeskér was completed

The construction of the sewerage system in Nemeskér, a village with just over two hundred inhabitants belonging to the neighbouring district of Lövő, was carried out by SWIETELSKY Magyarország Kft. In this investment, the collected sewage was directed to the sewage treatment plant in Lövő, which has sufficient free capacity to handle the additional load from this settlement.

The project was implemented as part of the „Modernisation and expansion of the wastewater treatment plant in Kunsziget and the surrounding area” investment, in the general construction of Colas Alterra Zrt.

The project has just been officially handed over, but the technical handover by the contractor took place well ahead of schedule - on 6 August. Following the completion of the pressure pipeline construction, the pipeline was qualified with a 24-hour pressure test, which was repeatedly checked by the technical inspector together with the contractor, Győző Berta, SWIETELSKY Magyarország's site manager, told us.

A year ago, our newspaper presented the ongoing works with on-site photos. Since then, the construction and pressure testing of the sewage pressure pipe has been completed, and experts have restored the affected road and pavement surfaces in accordance with the original layer order.

In addition, the project has built

• 1 657 fm DN 200 PP gravity sewer,
• 108 DN 150 PP house connections,
• and 2 public sewage interceptors.

The depth of the challenges

As previously reported, the challenge of the project was the Sc-4-0 pipeline section, which was the deepest part of the network. Here the technicians had to dig down to 5.3 metres. Moreover, this section is located in the narrowest street, with a double row of pylons, crossing overhead lines and a vulnerable eternite water pipe. The replacement of the water main was unavoidable due to the narrow street cross-section. The ditch was supported by a system of dikes, which meant that the excavator could only work with extreme caution.

The key to success

The rapid progress of the works is also due to the favourable weather conditions, but the project manager emphasised the high quality of the project management and the good organisation of the colleagues, as well as the 20 years of experience of the physical staff. These combined to make the project a success. Mr Berta also mentioned the excellent cooperation between the parties involved. A good working relationship was established between the client, the municipality of Nemeskér, the operator Soproni Vízmű Zrt., the main contractor Colas Alterra and SWIETELSKY Magyarország.
