Scope of work

Das bestehende Reservoir in der Bühlenweid aus den 1960er‑Jahren ist sanierungsbedürftig und wird durch einen Neubau an neuem Standort ersetzt. Für die Erschliessung wird eine temporäre Baupiste von der Güterstrasse Bielen zur Bühlenweid erstellt.

Der Neubau umfasst zwei Kammern mit je 200 m³ Volumen. Er wird überwiegend in Ortbeton erstellt, mit Stahlbauteilen sowie nachträglichen Rohrdurchführungen. Vorgesehen sind eine Flachfundation und eine 3–9 m tiefe Baugrube mit Nagelwand sowie teilweise freien Böschungen.

Das Bauwerk wird überschüttet, vor dem Reservoir ist eine Blockmauer geplant. In den Kammern werden spezielle Abdichtungen eingebaut, zudem werden Vorbereitungen für ein späteres Trinkwasserkraftwerk getroffen.

Bestandteil des Projekts ist auch der Ersatz der bestehenden Trinkwassertransportleitung sowie weitere Anpassungen und Erweiterungen an Werkleitungen.
