Reusing Water

Millions of gallons of industrial wastewater is recycled at LANL by virtue of a long-term strategy to treat wastewater rather than discharging it into the environment.
April 12, 2012

Water from cooling the supercomputer is release to maintain a healthy wetland.

We reuse the same water up to six times before releasing it back into the environment cleaner than when it was pumped.

How many times does LANL reuse water?

Wastewater is generated from some of the facilities responsible for the Lab’s biggest missions, such as the cooling towers of the Los Alamos Neutron Science Center, one of the Lab’s premier science research facilities, and the Strategic Computing Complex, which creates world-class, high-performance computing production systems.

LANL diverts treated sanitary wastewater and water flushed from cooling towers to the Sanitary Effluent Reclamation Facility (SERF).

This treated wastewater is then reused in cooling towers around the Laboratory.

Innovations for a secure nation

Novel rocket design flight tested

Novel rocket design flight tested

The new rocket fuel and motor design adds a higher degree of safety by separating the fuel from the oxidizer, both novel formulations that are, by themselves, not able to detonate.
