What Is Cremation by Water?

In providing families with compassionate, personalized service to honor their loved ones, we are often asked for natural or environmentally friendly options. One increasingly popular choice is cremation by water, also known as alkaline hydrolysis or “aquamation.” This gentle process offers a modern twist on traditional methods.

Not only does it use 90% less energy than flame cremation, but it also produces zero emissions like mercury or greenhouse gases. No flame means a smaller carbon footprint, which aligns with families who are passionate about sustainability.

Using a water-based process, the body is gently reduced to its basic elements, mimicking the natural decomposition that occurs over time in the ground. A specialized stainless-steel vessel is filled with a solution of warm water (around 300°F) and alkali (a natural salt like potassium hydroxide). Over 3-4 hours, the combination of heat, pressure, and alkalinity breaks down organic tissues through a chemical reaction called hydrolysis.

What remains are bone fragments (very similar to cremation using a flame), which are then processed into a fine, ash-like substance. Any metal implants are removed and recycled. Survivors then receive the ashes in an urn, just as with traditional cremation.

While not for everyone, aquamation appeals to eco-conscious individuals, those seeking a “green” burial alternative, or families wanting a peaceful, water-symbolic farewell (water often represents renewal in many cultures). It’s fully compatible with religious views that allow cremation, and we can incorporate viewings, funerals, or custom ceremonies before the cremation process takes place.
