Services
Septic Tank Pumping
Our professional pumping services ensure optimal septic system performance through complete waste removal. We use high-capacity equipment to thoroughly clean tanks while following environmental regulations. Regular maintenance prevents costly backups and extends system lifespan for residential and commercial properties.
Portable Toilets
We provide clean, well-maintained portable toilets for construction sites, agricultural operations, weddings, and special events. Our fleet includes standard units and luxury restroom trailers with climate control. Delivery, servicing, and pickup are included in all rental agreements across six Washington counties.
Drain Field Restoration
Our specialized restoration process rejuvenates failing drain fields using advanced techniques. We diagnose system failures through video inspection then implement targeted repairs. Services include soil fracturing, line replacement, and bacterial treatment to restore proper drainage and prevent environmental contamination.
Video Inspection
High-resolution cameras allow precise identification of pipe blockages, cracks, and root intrusions. This non-invasive method reduces excavation needs while providing real-time visual documentation. Inspections help determine whether repairs or replacements are needed for septic tanks, sewer lines, and drain fields.
Grease Trap Maintenance
We service restaurant grease traps and industrial waste systems to prevent clogs and regulatory violations. Our technicians perform thorough cleaning, sludge removal, and system checks. Regular maintenance ensures compliance with local sanitation codes while maintaining optimal drainage performance for food service establishments.
