How Are Alkaline Hydrolysis Facilities Designed for Cremation?
By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15
Alkaline hydrolysis facilities are designed around the process vessels: heavy-duty plumbing with effluent neutralization and cooling, substantial hot water capacity, humidity-controlled ventilation, and sewer-authority-compliant discharge — inside a calm suite separated from public areas.

Process plumbing and hot water
The plumbing design is the heart of an alkaline hydrolysis facility. I size water service for simultaneous vessel fills, design drainage for large hot batch discharges with tempering to protect the piping and meet code temperature limits, and select pipe materials rated for high pH and temperature. The hot water plant — boilers or dedicated heaters with storage — is matched to the cycle schedule so vessels never wait for heat. Where the water supply needs treatment for the process chemistry, I include it. Every drain, vent, and cleanout is placed for a process that runs daily: accessible, robust, and maintainable.
Effluent compliance and the dignified suite
Effluent compliance is designed as a system: collection from the vessels, cooling and pH neutralization, batch holding with sampling ports, and controlled release to the sewer within the authority's limits — with metering and logging to prove it. I build the monitoring the permit requires into the construction documents. Around this process core, I design the suite families see: private arrangement rooms, a calm viewing area, warm lighting, and complete separation from the vessel room by construction and air systems. The building tells the truth about water cremation — a gentle process in a gentle place — because the engineering makes it so.
Alkaline hydrolysis facility checklist
Water cremation facilities blend process engineering with funeral dignity. This checklist covers both halves. • Vessel utilities sized from manufacturer cut sheets: water, drain, power, and heat for the full complement • Hot water plant with storage and recovery matched to the vessel cycle schedule • Drainage in high-pH, high-temperature-rated materials with tempering and accessible cleanouts • Effluent cooling, neutralization, and batch release designed to the sewer authority's permit • Ventilation managing process heat and humidity, keeping the suite comfortable and separated • Calm public areas with complete acoustic and air separation from the process suite
