New projects for pumping stations Infra Automation

Egemin’s Infra Automation division is working on several major infrastructure projects to automate the operation of pumping stations installed along Belgian rivers and canals. These stations are responsible for the regulation of the water level. The adaptation works are part of the projects on flood control of the Flemish Government. Egemin Automation will renew the electromechanical components of the controls or install completely new control systems. Flemish waterways authority Waterwegen en Zeekanaal (W&Z) and the Flemish Environment Agency are important clients in that respect.

AUTOMATIC CONTROL OF THE WATER LEVEL

In 1973 a dam was built between the River Durme and the Moervaart canal to protect the city of Lokeren from flooding by the Durme in bad weather conditions. However, this resulted in an unnatural discharge from the Moervaart to the Ghent-Terneuzen Canal, resulting in frequent flooding and silting of the tidal River Durme because of the lack of an upper flow rate. The construction of the pumping station will bring the upper flow back to the River Durme and in extreme circumstances the excess water in the Moervaart canal can be pumped to the Durme.

AUTOMATION AND RENEWAL OF ELECTRICAL INSTALLATION

Egemin will retrofit the obsolete pump installation at the lock complex in Zemst along the Brussels-Scheldt Canal. The lock complex ensures that sufficient water remains in the upper reach of the canal after ships have passed. The installation pumps the water back upward, so the ships coming from Antwerp and Brussels do not run aground.
Tom Haesebrouck: "The renovation of the pump complex is very urgent, the electrical system is severely outdated and the necessary spare parts are no longer available. Egemin will supply completely new controls and will also install a monitoring system that makes it possible to operate the installation remotely from the control tower."

CONTROLLED SEAWARD FLOW

The Maartensas discharge installation on the River Noordede in Bredene was in urgent need of renovation. This is demonstrated by the various floods the area had to deal with in recent years. "The installation consists of seven discharge sleeves that have sliding openings on the seaside and the landside," says Haesebrouck. “These discharge sleeves provide a controlled flow of water from the interior to the sea."

Egemin works on this project together with the Vrij Technisch Instituut Brugge (science and technology oriented secondary school in Bruges). "The students will build the control panels and help connect the installation in the field! In this way they learn to work on a real project and gain practical experience. A nice win-win situation,” says Tom Haesebrouck.

RENOVATION OF PUMPING STATION VLASSENBROEK

The renovation of the pumping station in Vlassenbroek is part of a major renovation project of the Flemish government. The Vlassenbroek polder is to partially become a flood plain and that is why the discharge capacity of the pumping station needs to be increased. That is the reason client Waterwegen & Zeekanaal called on the expertise of Egemin, which will replace the existing three pumps. Currently they each have a capacity of 1.2 m³/s, the new axial pumps will have a pumping rate of 2 m³/s.

RELIEF OF SEWER NETWORK AT GANSHOREN

An outsider in the series of infrastructure projects for pumping stations is the buffer basin near Ganshoren, which is part of an action plan of water authority Vivaqua in the Brussels Region. The buffer basin will be filled when sewage water levels are high to temporarily relieve the sewer network during short heavy rainfall. Egemin Automation will install two pumps that can subsequently empty the basin again, together with a flushing system and a smaller pump to clean the buffer basin and drain it completely. Egemin works on this project as a subcontractor of construction company Franki Construct, which is responsible for the construction of the buffer basin.
