Founded by Georges Hominal in 1946 in Bernex/Geneva, the company was active in the fields of parks, gardens, public works and earthworks until 1960, when it created its ‘Sanitation’ department, in which it has specialised for 79 years in Geneva and for 42 years (since 1983) in Haute-Savoie. The children of Georges and Nathalie Hominal: Françoise, André, and Jean-Michel are currently the company's directors, already joined by the new generation: Jessica Hominal, Tanguy Hominal, and Bérengère Hominal Hofer. Our presence in the Lake Geneva region, both in Switzerland (Geneva, the Vaud coast) and France (Haute-Savoie, Pays de Gex), makes our company your local partner for all your projects.

We contribute to the environment and ensure your safety...economically! REGULAR MAINTENANCE: CAN WE AVOID EMERGENCY INTERVENTIONS RELATED TO FLOODING, OVERFLOWS AND BACKFLOWS? By taking preventive action every year at this time, you are guaranteed service. We offer a maintenance contract at a very attractive price and systematically hydro-clean all your networks, clean water, waste water and drainage systems to ensure optimum flow, without ever experiencing the hassle of blockages or flooding. We manage the work by notifying you in writing, so you don't have to worry about a thing. WHAT TO DO IN THE EVENT OF ANOMALIES, COUNTER-SLOPES, BREAKS OR SUBSIDENCE IN YOUR PIPES? A VIDEO INSPECTION COMBINED WITH LASER SCANNING or colouring allows us to accurately diagnose the problems you have in your pipes. You can watch live as the camera moves through your pipes on our screen. We provide you with a USB key and a photographic report, as well as a quote to repair or replace the faulty pipes. OUR ‘PUBLIC WORKS’ DEPARTMENT carries out all repair work or installs new systems. CHEMICAL TOILET RENTAL - OUR ‘TURNKEY’ SERVICE COMPREHENSIVE SERVICE: We deliver the cubicle(s) and provide maintenance throughout the event if you wish (supply of paper, chemicals, water, cleaning of sanitary facilities, emptying of the tank). We then collect the cubicle, empty it and carry out a final disinfection. PVC CABINS, CLEAN, SELF-CONTAINED, NO CONNECTIONS REQUIRED, WITH OR WITHOUT WATER TANK FOR THE HAND WASHBASIN, WITH OR WITHOUT FLUSH, WITH OR WITHOUT LIGHT, according to your needs. We rent autonom toilet cabins for outdoor events when sanitary facilities cannot be temporarily installed. These self-contained cabins, without sewer connections, allow you to have clean toilets, with or without a flush, with or without a sink, depending on your budget and needs. For a construction site, a temporary installation in a field, a ball, a party, a circus, a reception, a wedding, a celebration, a birthday, a competition, anywhere where toilets would be an asset. TREES AND THEIR ROOTS: Pipes are often still made of concrete, and even when they are made of PVC, they can have small cracks or faulty joints that allow roots, which are always looking for water, to penetrate. Root growth very quickly causes ‘rat tails’, i.e. an impressive amalgamation of roots that completely block your pipes, whether they carry clean water or waste water. Annual hydrocleaning prevents these problems and allows you to maintain your vegetation without being bothered by roots. VERMIN AND RODENTS IN YOUR PIPES: Saturated sewage and clean water systems are ideal for vermin and rodents. Unsanitary conditions caused by insufficient or non-existent maintenance of your pipes are often the cause of vermin (spiders, cockroaches, rats). We are available 24 hours a day, at night, on weekends and public holidays. Just call 022.757.16.49.
