FACILITY PLANNING
Drainage & Waste Planning for Anatomy & Pathology Labs
Floor drains, sumps, specimen waste, formaldehyde discharge. Content current as of May 1, 2026.
Every autopsy room, anatomy lab, and pathology lab needs a drainage plan. Poor drainage causes odor, contamination, and facility damage.
Floor Drains
Slope: Minimum 1/8 inch per foot toward drain. Drain location: Near autopsy/dissection table and sinks. Grating: Removable grates for cleaning. Trap: P-trap or S-trap filled with water to prevent backflow and odor.
Sump Pit
Capacity: Design for daily volume plus washdown. Covers: Sealed, vented. Pumping: Plan for regular removal of accumulated liquid (typically weekly to monthly).
Specimen Disposal
Small tissues (biopsies, grossed material): Biohazard sharps containers, then incineration or pathological waste disposal per local regulations. Larger specimens (post-autopsy): Cremation or regulated medical waste contractor. Formalin-contaminated materials: Hazardous waste classification depends on concentration; consult environmental health.
Waste Water
Formalin discharge: Consult local sewer authority and environmental agency. Some jurisdictions allow diluted formaldehyde to sewer; others require pre-treatment or tanked disposal. Pre-treatment: Neutralization or filtration may be required before sewer discharge. Documentation: Keep records of all specimen waste and chemical disposal.
USPE Equipment Drainage Features
All USPE autopsy tables, dissection tables, and workstations have integrated drainage with PVC ball-valve drains for easy access and flow control. Removable grates support cleaning and drain maintenance.
