Discover Ortec Environnement Alzéo Ouest

Sustainable, Controlled Sediment Management Solutions
Ortec Environnement teams support you in managing sediments from rivers, canals, ports, or basins. These environments are naturally subject to progressive siltation, a phenomenon intensified by:

• Flat topography
• Low flow rates
• Erosion processes
• Urban or industrial discharges

Technical Solutions Tailored to Each Site

To address these challenges, we implement proven, scalable processes adapted to site conditions and volumes to be treated:

• Sediment pumping and dredging
• Network unclogging to restore hydraulic flow
• Sludge and sediment flocculation to accelerate separation
• Dewatering of flocculated materials using filter boxes, geocontainers, lagoons, or settling basins
• Water treatment and clarification to allow discharge into the natural environment in compliance with regulations
• Removal of materials to approved, appropriate treatment or recovery channels

Waste Reduction and Controlled Environmental Impact
Our methods are part of an eco-responsible approach with a clear objective: reducing the quantity of waste generated, for our clients and for the planet.

The Ortec Group has know-how and proficiency in a broad variety of techniques to offer custom industrial cleaning solutions. From one-off services to the overall “Clean Factory” agreement, our teams master a wide range of techniques and processes, whether manual or mechanized, for your industrial site. You can be confident in the long-term reliability and performance of your installations, as well as in the integrity of your processes.

Our teams are CATEC-certified (Certificate of Aptitude for Working in Confined Spaces) for work in confined spaces.
They also hold the electrical authorizations required for work on lift pumps and electrical panels.

We are able to carry out various cleaning operations:

• Individual and collective sanitation systems: all-water tanks, septic tanks, grease traps, sumps
• Unclogging of all types of networks
• Hydrocleaning of wastewater and stormwater pipes using recycling hydrocleaning units
• Cleaning of stormwater inlets and collection grates
• Lift stations
• Maintenance, repair, or replacement of lift pumps
• Pumping and cleaning of retention basins, lagoons, tanks, and more
• Digester cleaning and grit chamber maintenance
• Cleaning of ballast tanks, holds, and cargo residues
• High-pressure cleaning and surface treatment (concrete floors, walls, pedestrian
  surfaces, and more)

These processes offer multiple benefits and support our main objective: reducing waste volumes for our customers and for the planet.

Wastewater and Stormwater Network Diagnostics: Comprehensive Expertise
As specialists in wastewater and stormwater network diagnostics, we offer a comprehensive service combining advanced technologies, certified operations and in-depth defect analysis.

Our Diagnostic Services

• CCTV inspections using high-definition cameras with integrated zoom to identify all types of defects (cracks, breaks, root intrusion, etc.)
• Network watertightness testing to verify system compliance
• Compaction testing of trenches and backfill to verify structural stability

Our equipment enables precise detection of anomalies, including in difficult-to-access areas. Thanks to CATEC certification for work in confined spaces, our teams are authorized to operate safely in all types of networks.

Comprehensive Support for Your Networks
We provide comprehensive diagnostics through complementary services:

• Pre-inspection hydrocleaning of networks to ensure optimal inspection conditions
• Geolocated inspections with XYZ positioning and detection of extraneous water inflows
• Georeferencing of buried networks
• Tracing of existing networks
• Connection testing using smoke, fluorescein, or UV methods
• Creation or updating of AutoCAD DWG / GIS network plans
• Detailed inspection reports with analysis of identified defects
• Costed estimates for rehabilitation or compliance works

Diagnostics for Technical Expert Assessments
We also carry out diagnostics in connection with:

• Insurance assessments: claims, infiltration issues, and more
• Judicial expert assessments in support of legal proceedings

Accidental pollution can have serious consequences for human health, the environment, and economic activity. This is why Ortec teams are trained, equipped and ready to respond quickly to any type of environmental incident.

Rapid pollution response – 24/7

We can mobilize the necessary equipment within very short timeframes to respond effectively to the following situations:

• Road accidents involving leaks of polluting substances
• Fires that have generated toxic runoff or residues
• Accidental spills of hazardous substances
• Fuel transfer incidents (overflows, transfer errors, etc.)
• Hydrocarbon pollution: diesel, fuel oil, gasoline, and other fuels
• Leaks from domestic or industrial fuel oil tanks
• Pollution of natural environments: groundwater, wells, rivers, lagoons, etc.
• Collection of floating waste in port and marine areas

Immediately Deployable Personnel and Equipment
Our teams are specifically trained in environmental emergency response. We have:

• Ready-to-use equipment stored in emergency response containers
• Vehicles and containment and pumping equipment
• 24/7 response capability across western France

A Rigorous Methodology to Limit Impacts
During each intervention, our priorities are to:

1. Secure the polluted area
2. Contain runoff or hazardous materials
3. Collect and treat waste while reducing waste volumes and environmental impact

Privately owned fuel distribution facilities are subject to mandatory regulatory inspections and operations depending on their storage capacity and annual throughput.

We also verify leak detectors and test the integrity of fuel tanks and pipelines.

Our teams are qualified to carry out these inspections and provide various petroleum-related services at service stations, industrial sites, and private individuals:

• Pumping and maintenance of hydrocarbon separators
• Cleaning of all hydrocarbon tanks and containers
• Cleaning, degassing, and neutralization of tanks and compartments
• Acoustic tightness testing of tanks
• Inspection of leak detection systems on double-walled tanks
• Leak detection
  Pipeline flushing and degassing
• Event purging
• Lagoon pumping
• Work on ICPE-classified facilities
