About Ripalgo AG
Ripalgo AG, based in Rüthi SG, is a manufacturer-independent Swiss system provider for plastic tanks. With more than 15 years of experience in the field of water and wastewater tanks, the company manufactures and finishes in its own in-house production facility drinking water reservoirs, spring catchment shafts and well chambers, rainwater tanks and complete rainwater utilization systems, retention tanks, drain-free wastewater tanks and collection pits, as well as heating oil, diesel and AdBlue® tanks and industrial containers. Materials are thick-walled polyethylene (PE/PE-HD/HD-PE), GRP for collection trays, galvanized or plastic-coated steel for bandages and outer shells, and stainless steel for trays and lids. Connections are welded in according to customer requirements, and tanks can be finished with cladding made of larch or Douglas fir wood. Volumes range from rain barrels from 220 liters up to tanks with 50'000 liters; delivery is made ready for connection directly to the construction site, including by helicopter to exposed locations. Customers include private households, trade businesses, agriculture, municipalities, gastronomy and construction sites in Switzerland and Liechtenstein.
