What Liquid Waste Solutions does

Liquid Waste Solutions (DBA Pump Truck Houston) is a private, Houston-based environmental services company founded in 1994 that provides commercial liquid waste collection, pumping, cleaning, and inspection across the Houston metropolitan area. Its service portfolio covers grease traps, grit traps, lint traps, storm traps, lift stations, wash water recovery, trap inspection, sample well inspection, and grease trap odor remediation — each anchored by City of Houston quarterly compliance mandates and TCEQ exposure risk for non-compliant customers. The company's core operational asset is a fleet of heavy-duty pump trucks equipped with hoses and pumps roughly twice the size of standard units, enabling faster cycle times, 4:00 AM start windows, and Saturday availability for high-traffic commercial customers.

The business runs on a transaction-based revenue model with quote-based, pay-as-you-go pricing and no disclosed subscriptions or recurring contracts. Customers include restaurants and commercial kitchens (primary), pressure-washing contractors, car washes and auto repair shops, commercial laundromats, and apartment complexes — all acquired largely through phone, email, the company website (pumptruckhouston.com), and a lightweight customer portal via Method Integration. The owner-operator emphasizes regulatory know-how and problem-solving expertise as the core value proposition, with documented multi-decade customer relationships (e.g., a McDonald's owner-operator of 15+ years). There is no evidence of external capital, M&A activity, geographic expansion outside Houston, or material headcount growth over its 30+ year history.

Broad incumbents

• Stericycle: Large regulated waste management company with broader services (sharps, medical, document destruction). Adjacent in regulated waste collection but with a much wider portfolio than LWS's specialized trap services.
• Heritage-Crystal Clean: Public environmental services company offering waste oil collection, parts cleaning, and industrial waste services. Tangentially comparable in liquid waste collection capabilities for commercial customers.
• Clean Harbors: Major North American provider of environmental, energy, and industrial services including hazardous waste management. Comparable in liquid waste handling capabilities but at substantially larger scale and broader scope.
• Waste Management Inc. Largest U.S. waste services company offering commercial collection, recycling, and disposal. Operates a small commercial liquid waste segment but primarily competes in solid waste rather than grease trap specialty services.
• Darling Ingredients: Large publicly traded rendering and used cooking oil collector with a commercial FOG recycling segment. Operates at significantly greater scale than LWS but competes in the downstream FOG collection value chain.

Direct peers

• Wind River Environmental: Largest U.S. provider of grease trap cleaning, drain cleaning, and liquid waste pumping services for commercial customers. Directly comparable to Liquid Waste Solutions in core service offering (grease trap pumping) and customer base (restaurants and food service).

• Liquid Environmental Solutions: National provider of grease trap cleaning, used cooking oil collection, and liquid waste services to restaurants and food service operators. Highly comparable business model and service portfolio to LWS's grease trap and FOG offerings.

Regional players

• Texas Pride Septic & Liquid Waste: Texas-based liquid waste hauler offering grease trap pumping, septic services, and lift station maintenance. Comparable in core offering but extends across Texas geographies rather than being concentrated in Houston metro.
