About Etertub
Etertub AG, headquartered in Bilten (Canton of Glarus), develops and implements structures for modern drinking water supply. The product portfolio comprises individually prefabricated well chambers and spring shafts, PE reservoirs with volumes up to 500 m³ (pipe containers with diameters of 1500 to 3500 mm), valve and water meter shafts made of profile-wound pipe, concrete protection panels, the KLS filter for slow sand filtration as well as accessories such as well covers, frog valves, strainers and LED underwater lights. In addition to new production, the company offers the interior rehabilitation of drinking water tanks using the ETERTUB-aqua/HYDRO CLICK process. The value chain includes CAD planning, factory prefabrication, transport, installation, commissioning and cleaning. Materials are mainly PE 100 and PE-HD, stainless steel (1.4301/V4A), brass, red bronze and GJS 400. Customers are predominantly from the municipal drinking water supply sector, including projects such as the reservoir for the Gotthard motorway A2 near Quinto (TI) and reservoir rehabilitations in Bessinge and Ebrüti.

Materials & Processes
Polyethylene PE 100
Solid-wall wound and pipe material for well chambers, spring shafts and valve shafts with a smooth inner surface.
High-density polyethylene
Material for accessories such as frog valves, strainers and mounting brackets.
Chromium-nickel steel (V4A/V2A)
Pickled stainless steel for well covers with safety lock and gasket.
PET-G
Drinking-water-safe plastic of the ETERTUB-aqua-Lux LED underwater light.
AGRUSAFE PE concrete protection panels
Thermoplastic protection panels that are joined by butt, extrusion and hot-wedge welding and protect concrete structures against chemical attack.
GJS 400
Material of the shaft covers of the water meter shaft (load classes B 125 / A 15).
Brass and red bronze
Components of the meter set and the ZAK connection in the water meter shaft.
EPDM and TPE
Elastomers for gaskets of the water meter set and well covers.
