“Blocked drain or sewage backflow”
In the event of sewage backflow or any critical situation, we respond as a priority, 24/7, to get your drainage network flowing again quickly.
Immediate check of the pipe's condition and the possible causes of the blockage.
Sink not draining, toilet blocked, wastewater backing up? We respond quickly to unblock your drains and restore the flow through your network without damaging your installations. Equipped with manual or mechanical tools, our technicians clear localised blockages (paper, wet wipes, deposits, objects).
For more serious obstructions or heavily fouled drains, a high-pressure water jet thoroughly removes grease, scale and residue.
A clear, documented report of the work we carried out – invaluable for an insurance claim after damage, or when further works need to be planned.
“Leak, infiltration or odour problem”
Our team responds 24/7 to trace leaks or detect odours.
Have you noticed a leak, infiltration or unusual odour in your drainage system? We come straight to your site to analyse the network and pinpoint the source of the problem, using non-invasive detection techniques designed for drains. If the diagnosis reveals a fault, we carry out a targeted repair, with no unnecessary work or excessive opening-up of your installation.
Using a camera mounted on a push rod or on a self-propelled robot, inserted directly into the pipes, we see inside the network in real time and spot the cracks, faulty joints, roots or obstructions behind a leak, infiltration or odour.
A smoke machine connected to the network injects non-toxic smoke under slight pressure, quickly revealing leaks or poorly ventilated points, which are often the cause of odours rising back up.

“Pumping needed”
An overflow won't wait. Our team responds quickly to all your pumping needs.
We respond quickly to all your pumping needs, with equipment suited to each type of installation. On every job, the waste collected is taken to an approved treatment facility, in line with environmental regulations.

For regular preventive maintenance, we offer a tailor-made maintenance contract with scheduled visits (once a year or at the frequency that suits your installation). This option helps you keep your costs under control, monitor the condition of your installation over the long term and anticipate breakdowns before they happen.
“Checking the condition of my drains”
Anticipating problems is the first step to fixing them. A well-monitored network is a network that lasts.
Want to know the real condition of your drainage system, before buying or selling a property or simply as a precaution? We carry out a full survey of your drains using CCTV inspection. This technique detects cracks, sagging, intrusive roots, faulty joints, deposits or obstructions, without any digging or damage.
After the inspection, we give you a detailed report with images or video footage, setting out the condition of the network and any faults found, along with our recommendations for work where needed. A clear, documented report you can rely on for decision-making, an insurance claim or upcoming works.

“Maintaining my drains”
Well-maintained drains, guaranteed peace of mind. We offer two options to suit your needs.
Even without a contract, regular maintenance reduces the risk of blockages, odours or premature deterioration of your drains. We carry out high-pressure water jetting to remove the deposits, grease and sediment that have built up in your drains. This restores proper flow through your network.
For regular preventive maintenance, we offer a tailor-made maintenance contract with scheduled visits (once a year or at the frequency that suits your installation). This option helps you keep your costs under control, monitor the condition of your network over the long term and anticipate breakdowns before they happen. The contract gives you peace of mind. You know a professional is taking care of your network.
“Checking my pumping station”
Your pumping station deserves monitoring that lives up to the role it plays.
A pumping station needs regular checks to keep it working properly and avoid any risk of breakdown or overflow. We clean, check and adjust every component of lifting stations. After checking the pumps, the safety systems and mechanical parts such as valves and non-return valves, we give you a job report setting out the condition of the station and our recommendations, particularly if we find a fault that requires a repair or a replacement part.

“Soil stacks”
The soil stack carries wastewater from every floor: when it becomes blocked, the whole building backs up. We clean, inspect and maintain soil stacks in multi-storey buildings.
Grease, scale and deposits gradually reduce the usable diameter of the stack. We clean and unblock soil stacks along their entire height, including branch connections and stack bases, to prevent backflow into lower-floor flats.
A CCTV inspection reveals the inside condition of the stack: cracks, corrosion, faulty connections. It also allows an up-to-date plan of your installations to be drawn up, as now required under Geneva's water law.
Add your soil stacks to a maintenance contract, alongside the horizontal sewer mains: scheduled visits, monitoring of the vertical network's condition and cleaning before blockages occur.

From your first call to prevention, three clear steps to solve the problem for good and stop it coming back.
By phone, by email or using the form: you describe the situation, how urgent it is and the context (private or business customer).
On site, we assess the cause and apply the right technique (drain unblocking, high-pressure water jetting, CCTV inspection…).
We explain what caused the problem and how to stop it happening again (maintenance, drain cleaning, inspections).

Sustainability
At Amoudruz SA, responsibility is about more than intentions. It shows every day, in the field, through well-controlled practices and concrete operational choices.
Learn morePrecise diagnosis leading to appropriate, effective action, limited to what is strictly necessary.
Optimised journeys and careful use of water, combining performance with restraint.
Clean, safe and well-organised work to minimise disruption for sites and their users.
The price depends on the type of blockage, access and the technique required (drain snake, high-pressure water jetting…). We provide a free quote before any work: describe your situation by phone or using the form.
Our emergency service is available 24/7 across Geneva and La Côte. Critical situations (sewage backflow, unusable toilets or bathrooms) are handled as a priority.
It is a method of drain cleaning using high-pressure water: it dislodges grease, scale and residue along the entire length of the network. It is the most lasting solution for heavy or recurring build-up.
It depends on the type of building and how it is used: a heavily used block of flats or shop needs more frequent cleaning than a detached house. A maintenance contract lets you set the right frequency and avoid emergencies.
CCTV inspection lets you see inside the network without destructive works: cracks, deposits, breaks or defects that would otherwise be invisible. It is particularly recommended before buying a property or in the case of recurring problems.
We cover Geneva and La Côte. Our depot is located in Les Acacias, so we can be on site quickly.
Describe your situation (emergency, maintenance, diagnosis, private or business customer). We will quickly point you to the most suitable solution.
