Alwatec

What Alwatec does

Alwatec AG is a Swiss engineering and environmental technology company headquartered in Bellach (Solothurn), operating as a wholly-owned subsidiary of Marti Gruppe, a family-owned Swiss construction conglomerate with approximately 80 group companies. The company is structured in two divisions under one corporate umbrella: Haustechnik (Building Technology), which provides pipeline construction (Werkleitungsbau), plant construction (Anlagenbau), sanitary/plumbing, and heating services; and Umwelttechnik (Environmental Technology), which functions as a general contractor (Generalunternehmung) for water, wastewater, and exhaust air treatment systems. The environmental technology division delivers complete turnkey solutions spanning concept development, project engineering, execution, commissioning, staff training, operation, maintenance, and monitoring, and also rents mobile treatment equipment for temporary deployments.

The technology stack centers on mobile and stationary treatment plants (15 l/s neutralization systems with CO2 dosing, lamella separators, flocculation, and online monitoring), pre-configured pump stations using Andritz pumps with integrated level measurement and SMS alerting, and the proprietary Datenlogger System 'MUC' for continuous remote monitoring, data recording, archiving, and anomaly notification. Documented treatment capacities reach up to 300 l/s for tunnel construction water, with pump systems delivering up to 100 kW and 7,700 l/min. Alwatec holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications issued by SQS/IQNET.

The company generates revenue primarily through project-based engineering contracts with municipalities, cantonal and federal government agencies (including SBB CFF FFS, ASTRA), large construction firms and ARGE consortia (Marti Infra AG, Groupement Marti Nations, Consorzio Gottardo), and select industrial clients (Axpo, DePuy Synthes). Notable projects include the CHF 8.5 million Gotthard A2 Second Tube water treatment contract and the CHF 2.1 million Semmering Base Tunnel (Austria) contract, alongside 35+ smaller municipal engagements. Distribution is direct and project-based, with Marti Gruppe providing both internal demand and corporate infrastructure support. The company operates primarily in Switzerland with documented project execution in Austria and France.

Core offering

Alwatec AG operates two business divisions: Haustechnik (building technology) covering sanitary, heating, and plumbing installations, and Umwelttechnik (environmental technology) supplying engineered water, wastewater, and exhaust air treatment plants, neutralization systems, pump stations, pipeline construction (Werkleitungsbau), plant construction (Anlagenbau), and MUC-based datalogger monitoring systems. Its customers are municipal authorities, government agencies, and industrial clients, primarily in Switzerland, executing flagship transit-infrastructure contracts such as the Gotthard A2 Second Tube and Semmering Base Tunnel.

Product overview

Alwatec operates as a dual-division company within the Marti Group: Haustechnik (Building Technology) and Umwelttechnik (Environmental Technology). The Environmental Technology division functions as a 'general contractor' providing complete systems for water, wastewater and exhaust air treatment, encompassing concept development, project planning, execution, commissioning, personnel training, operations, maintenance and monitoring. Core products include mobile and stationary wastewater treatment plants, neutralization systems, pump stations, pumps, and data logger systems for remote monitoring. The Building Technology division offers pipeline construction, plant construction, sanitary, and heating services. The two divisions share a location but operate independently under the Alwatec AG corporate umbrella.
