Clensol S.A.

What Clensol S.A. does

Clensol S.A. is a Swiss water management and pool engineering firm operating from Puidoux, Vaud, in the French-speaking region of Switzerland (Suisse romande). Established in 1935 as the Swiss branch of Clensol Ltd (founded London, 1927), the company designs, constructs, and maintains custom swimming pools (mirror, infinity, indoor, municipal, hotel, Olympic, skimmer), decorative water features (fountains, water tables, water walls, artificial rivers), hydrotherapy and rehabilitation pools, bubble/hydromassage pools, and paddling pools. Its technical installations span filtration systems (sand, diatomaceous earth, active charcoal), pumping systems branded Surflo, chemical dosing equipment, and cathodic protection, alongside broader water treatment applications covering softening, drinking water, osmosis, homogenization, neutralization, wastewater, and sewage plant management.

The company generates revenue through three streams: project-based construction and renovation contracts for new pools and basins; customized annual subscription service contracts covering commissioning/decommissioning, scheduled technical support, facility monitoring, and consumable product delivery; and a small online boutique selling water treatment consumables (sterilizers, acids, water testers, treatment products) to existing customers. Customer segments include private residential clients (primary), public and institutional buyers (municipal and school pools), hospitality (hotels, resorts, spas), and healthcare/therapeutic facilities. Go-to-market is enterprise field sales with direct engagement of property owners, architects, and institutional buyers across Suisse romande, supported by a bilingual (French/English) corporate website, project galleries, and a 24/7 emergency hotline. Pricing is custom-quoted per project and per service tier; no public pricing exists. The firm is privately held with no disclosed revenue, funding rounds, or M&A activity.
