Abstract
The Sanitary Waste System (SWS) at Los Alamos National Laboratory (LANL) is an extended-air, activated sludge wastewater treatment facility that is designed to treat 0.6 million gallons per day (MGD). However, the facility rarely receives more than 0.3 MGD and occasionally less than 0.1 MGD. Lack of sufficient flow and organic concentration into SWS, particularly on weekends and holidays, results in an inconsistent and often very low biochemical oxygen demand (BOD). Shortage of organic material leads to routine operation weaknesses and leaves SWS vulnerable to significant problems resulting from small amounts of toxic influents. The addition of residential influent from Los Alamos County will supply organic load to decrease this vulnerability, and improve nitrification during cold weather, weekends and holidays. Additional benefits include conservation of 223 acre-feet per year and significant savings when project dollars are not discounted. The project will also generate significant benefits not easily quantified, such as water for future LANL projects, and good will in the community.
