ISAS

What ISAS does

ISAS GmbH (Ingenieurbüro für Kanalsanierung) is a privately held, family-owned German engineering firm founded in 1989 in Füssen by Peter and Irene Jung, specializing in the assessment, planning, and construction supervision of sewage system rehabilitation. The company is now led by the second generation — Strategic Managing Director Alexander Jung and Commercial Managing Director Florian Jung — alongside long-tenured senior engineers Klaus Burghard and Peter Glatz. ISAS employs approximately 100 staff across five permanent German offices (Füssen, Albstadt, Erlangen, München, Würzburg) plus project locations in Deggendorf, Düsseldorf, and Linz (Austria), with the Würzburg branch opened in 2025 and the Austrian branch established in 2015.

The firm's core offerings span five interconnected service lines: Zustandsbewertung & Dokumentation (condition assessment, TV inspection, GIS-based documentation via ISAS's proprietary GIS-Viewer), Grabenlose Kanalsanierung (trenchless rehabilitation for pipe diameters up to 1600mm), Kanalsanierung in offener Bauweise (open-construction rehabilitation for special cases), Großprofile & Sonderbauwerke (large-diameter and special-structure projects), and Industrielle Abwassernetze (industrial wastewater networks). ISAS holds the RAL-Gütezeichen Kanalbau certification — the first engineering firm in Bavaria and second in Germany to receive it (2009) — alongside ISO 9001-aligned internal quality management and a Gemeinwohl-Ökonomie certification (2023/2024).

ISAS generates revenue through project-based B2B engineering services billed per engagement, typically under the HOAI (Honorarordnung für Architekten und Ingenieure) fee structure for engineering services. Customers are split across three segments: municipalities and public utilities (e.g., Landeshauptstadt München, Landeshauptstadt Stuttgart, Stadtentwässerung Augsburg, Gemeinde Feldkirchen-Westerham), industrial enterprises (Mercedes-Benz, Audi, Porsche, Daimler Truck, 3M Deutschland, Veolia Industries Austria), and housing management companies. Sales run through a regional direct field-sales model with dedicated Kundenbetreuer covering named German territories.

Core offering

ISAS GmbH is a specialized engineering firm providing B2B services for the rehabilitation of sewage and wastewater systems, serving municipalities, industrial enterprises, and housing management companies across Germany and Austria. Its core offerings span the full project lifecycle—from condition assessment and GIS-based documentation through trenchless and open-construction canal rehabilitation planning to construction supervision and quality assurance. Services are delivered through project-based engagements with personnel located across five German offices and one Austrian project location.

Product overview

ISAS GmbH is an engineering firm specializing in the rehabilitation of sewage systems, offering a comprehensive portfolio of five interconnected service areas. The core offerings include Zustandsbewertung & Dokumentation (condition assessment and documentation) which provides the essential baseline data through inventory recording and TV inspection, feeding into all subsequent planning. Grabenlose Kanalsanierung (trenchless rehabilitation) and Kanalsanierung in offener Bauweise (open construction rehabilitation) represent the two main technical approaches to canal repair, with trenchless being the preferred method for standard diameters up to 1600mm. For larger dimensions and special structures, the Großprofile & Sonderbauwerke service handles planning and rehabilitation at different scales. Industrielle Abwassernetze extends these capabilities to commercial and industrial clients. Supporting these services is ISAS's proprietary GIS-Viewer, a web-based tool enabling mobile access to geographic data and infrastructure information.
