TAUBER | Der Kampfmittelräumer seit über 60 JahrenCookie Einstellungen
Im Auftrag der Emschergenossenschaft entsteht in Bottrop eine neue Retentionsbodenfilteranlage. Sie soll bei extremen Regenereignissen anfallendes, noch verunreinigtes Mischwasser aufnehmen und durch mehrere Schichten reinigen. Das Mischwasser fließt aus verschiedenen Bereichen zusammen und sammelt sich bei starken Regenereignissen im Stauraumüberlaufbauwerk. Wird dort eine bestimmte Wassermenge überschritten, gelangt das Wasser in den Retentionsbodenfilter, wo es gereinigt wird. Anschließend wird es über eine Überlauffläche wieder in die Boye geführt.
Für die Umsetzung übernimmt die Tauber Erdbau Umwelt (TEU) umfangreiche Erd-, Wasserhaltungs- und Leitungsarbeiten. Zu Beginn wurden Oberboden und vorhandene Aufschüttungen auf der rund 9.000 Quadratmeter großen Fläche abgetragen, zwischengelagert und zu einem großen Teil entsorgt.
Eine besondere Herausforderung stellte das anstehende Grundwasser dar. Um die Bauarbeiten durchführen zu können, wurde zunächst eine flächige Wasserhaltung eingerichtet. Unter der späteren Filterfläche entstand außerdem eine Grundwasser-Drainage. Sie sorgt dafür, dass Grundwasser kontrolliert abgeleitet wird und nicht in den Filterbereich aufsteigt.
Auf der Oberfläche wurde anschließend eine Kunststoffdichtungsbahn verlegt. Sie bildet eine zusätzliche Trennung zwischen dem Grundwasser und dem Wasser, das später durch den Retentionsbodenfilter gereinigt wird. Darauf werden die verschiedenen Filter- und Drainageschichten aus Sand und Kies aufgebaut.
Ein weiterer Schwerpunkt der Arbeiten liegt auf dem Aufbau des Entwässerungssystems. Dafür verlegt die TEU Drainageleitungen innerhalb der Filterschichten, die das gereinigte Wasser aufnehmen und zu Sammelleitungen führen. Über Schächte und größere Ablaufleitungen wird es anschließend zum Filtrat-Pumpwerk transportiert. Auch die dafür erforderlichen Leitungsgräben und Anschlüsse gehören zu den Arbeiten der TEU. Vom Pumpwerk gelangt das Wasser schließlich zur Überlauffläche und von dort zurück in die Boye.
Mit den Erd-, Wasserhaltungs- und Leitungsarbeiten schafft die TEU die Voraussetzungen für den späteren Betrieb der Anlage. Dazu gehört auch die Herstellung der Filterfläche mit ihrem mehrschichtigen Aufbau. Eine Trennwand teilt den Filter in zwei Bereiche. So kann später jeweils eine Hälfte erneuert werden, während die andere weiterhin in Betrieb bleibt.
Nach Fertigstellung wird die Anlage mit Schilf bepflanzt. Von außen wird dann vor allem eine große, grüne Fläche zu sehen sein – welche umfangreichen Erd-, Leitungs- und Bauarbeiten dahinterstecken, wird auf den ersten Blick kaum zu erkennen sein.
