Outfall 001
Outfall 001
for the
TA-3-22 Power Plant
Industrial Outfall 001 image
Description The discharge of about 300,000 gallons of treated water per day from Outfall 001 creates a continuous flowing perennial reach in upper Sandia Canyon and supports a 3-acre wetland. Water meets all regulatory standards. Most of the water comes from the Co-Generating Power and Steam Plant, which provides heating to buildings at TA-3 in addition to steam for process needs and to produce electricity in one 10-megawatt and two 5-megawatt steam turbines/generators.

Outfall 13S
Outfall 13S
for the
TA-46-347 Sanitary Wastewater System (SWWS) Plant
Industrial Outfall 13S image
Description Wastewater from sanitary sewer, other non-radiological drains and storm water from technical areas throughout the Laboratory are treated at the Sanitary Waste Water System Plant. Currently, no water is discharged at Outfall 13s. Treated sanitary effluent is pumped either to Outfall 001, or to the Sanitary Effluent Reclamation Facility (SERF) for tertiary treatment and reuse at the Strategic Computing Complex cooling towers. Outfall 13s is a sampling point after final treatment processes prior to pumping to Outfall 001 or to the SERF.

Industrial Outfall 051 image
Description The Radioactive Liquid Waste Treatment Facility treats low level and transuranic radioactive liquid wastewater. A mechanical evaporator was installed so no water has been discharged at Outfall 015 since November 2010. Should the evaporator be offline, wastewater would then treated and discharged in batches to Mortandad Canyon. Discharged water meets all regulatory standards.

for the
TA-16-1508 High Explosives Wastewater Treatment Facility (HEWTF)
Industrial Outfall 05A055 image
Description The High Explosive Wastewater Treatment Facility (HEWTF) treats high explosive contaminated wastewater, storm water, and cooling tower blow-down from various sites in the southeast section of the Laboratory. Since an evaporator is normally used, the HEWTF has not discharged since November 2007. Should this malfunction, high explosives wastewater influent is effectively treated through multiple processes before being discharged into Cañon de Valle.

TA-3-2274 Sigma Cooling Tower
Industrial Outfall 03A022 image
Description Water discharged here includes treated cooling tower blow-down water and storm water from roof drains which is then discharged into Mortandad Canyon. Discharged water meets all regulatory standards. Under emergency facility shut down due to a power outage emergency cooling water, which is potable, overflows from the circulating water pump basin directly to this outfall.
