What is Hydrovac Waste?
Hydrovac waste, also called slurry waste, is the combination of excavated soil and water collected in a debris tank during hydro excavation. This mixture may contain topsoil, clay, sandy soil, rock, gravel, frozen ground material, and potentially contaminants such as salt, hydrocarbons, or drilling fluids near industrial sites.
Why Proper Disposal Matters
- Environmental Protection: Prevents contamination of water sources and soil
- Regulatory Compliance: Adherence to municipal, state/provincial, and federal guidelines
- Cost Efficiency: Minimizes hauling trips and landfill expenses
- Jobsite Safety: Reduces spill risks and maintains safe work environments
Best Practices for Hydrovac Waste Disposal
1. Know Local Regulations
Contractors should contact local waste facilities, stay informed on EPA or Environment Canada guidelines, and avoid illegal dumping practices.
2. Separate Clean vs. Contaminated Waste
- Clean Slurry: Can be disposed at soil recycling facilities or designated dumpsites
- Contaminated Slurry: Requires specialized treatment facilities
3. Use Approved Disposal Sites
Always dump at licensed landfills, slurry disposal facilities, or recycling centers that can dewater slurry for solid reuse.
4. Plan Efficient Hauling Routes
- Choose disposal sites near the jobsite
- Schedule dedicated dump runs for larger projects
- Consider transfer stations if facilities are distant
5. Explore Dewatering Options
Onsite or offsite dewatering systems remove excess water, allowing solids reuse as backfill and water recycling for operations.
6. Track and Document Disposal
Maintain records of disposal locations, load volumes, weights, dates, and compliance forms for accountability and auditing.
7. Train Operators on Waste Handling
Crews should identify contaminated soil, prevent spills during offloading, and follow regulatory procedures.
Cost Considerations
Disposal costs depend on waste volume, facility tipping fees, distance to disposal sites, and waste type. Contractors can reduce expenses through dewatering bags, onsite separation systems, or partnerships with recycling facilities.
