What Is Water Cremation?

Water cremation, or aquamation, is a process that uses water, heat, and alkaline chemicals to break down the body after death. Unlike traditional cremation, which uses intense flames, aquamation relies on a gentle flow of water and a small amount of potassium hydroxide or sodium hydroxide. The body is placed in a stainless steel vessel, and over several hours, the process reduces the body to bone fragments and a sterile liquid. The remaining bone is dried and processed into a fine powder, similar to cremated ashes, which can be returned to the family.

How Does Water Cremation Work?

The aquamation process mimics natural decomposition but accelerates it using a controlled environment. The body is placed in a chamber filled with a solution of 95 percent water and 5 percent alkali. The solution is heated to around 300 degrees Fahrenheit, but at much lower temperatures than flame cremation. Over 6 to 8 hours, the body breaks down, leaving only bone and a liquid that is safely disposed of via the wastewater system. The process is gentle and respectful, with no direct flames or emissions.

Benefits of Water Cremation

• Eco-Friendly: Uses less energy and produces no harmful air emissions compared to flame cremation.
• Gentle Process: No flames or burning, making it a softer alternative for families.
• More Remains Returned: Families often receive up to 20 percent more remains than with traditional cremation.
• No Casket Required: Reduces the need for wood, metal, or other materials.
• Legal in Many States: Water cremation is now approved in a growing number of regions across the United States and worldwide.
