What etertub does

Etertub AG is a Swiss manufacturer of prefabricated polyethylene (PE) water-infrastructure components, headquartered in Bilten in the canton of Glarus. Its core product set comprises underground reservoirs (up to 500 m³ capacity), well chambers, renovation liners and the proprietary ETERTUB-aqua®, KLS® and HYDRO CLICK systems, with more than 4,000 chambers installed across Switzerland. The company holds SVGW certifications and ISO 9001:2015 quality accreditation, and its KLS filter carries the SolarImpulse Efficient Solution Label.

The company sells almost exclusively to Swiss municipal water utilities and public infrastructure owners on a project-by-project basis, with regional field-sales coverage that includes a Ticino office. Its business model is custom-engineered, prefabricated supply contracts that displace traditional in-situ concrete construction, reducing on-site civil-works time and cost. Notable reference projects include the Bessinge reservoir renovation for SIG Geneva and a fire-water tank for the ASTRA Gotthard A2 federal-road corridor.

Etertub operates as a private, small industrial company in the 11-50 employee band. It is operationally affiliated with Hawle Armaturen AG within the wider Hawle Group, sharing back-office functions and benefiting from cross-selling on fittings. There is no disclosed external funding, M&A activity, or international commercial footprint beyond the developing-country positioning of the KLS filter.
