Built in 1977, Raytheon Missile Systems Company’s (RMSC’s) centralized Industrial Wastewater Treatment Plant (IWTP) was designed to provide large volumes of high-quality reclaimed water for reuse in numerous on-site wet processes, while concurrently treating the resulting wastewater and chemical wastes generated from these processes. Piping systems transfer these by-products from the company to the IWTP. Currently, the Plant filtrates and processes approximately 170 gallons of wastewater per minute. The solids are collected and disposed as hazardous waste (about 20 cubic yards per month). The treated water is collected and discharged to the Pima County Treatment Facility at a rate of two million gallons per month. The IWTP has six holding tanks, each with a capacity of three million gallons.
However, current and anticipated transition activities (e.g., moving major wet processes to other Raytheon facilities) may decrease or eliminate future demands for the IWTP’s services. This loading reduction will substantially reduce the cost-effectiveness of the Plant in managing the company’s remaining regulated process wastewater and/or chemical wastes. In response, RMSC set up the Wastewater Strategies Team to simplify the treatment processes and its supporting infrastructure. The team will also revise and implement the necessary management practices for wastewater and chemical management. These efforts will help reduce the long-term operating and maintenance costs of the treatment plant. An important part of the strategy is to make current/future processes environmentally friendly and/or implement closed-loop, zero-discharge recycling systems. Besides reducing costs, these recycling systems will accelerate the Air Force’s and RMSC’s P2 initiative long-term goals and objectives. RMSC anticipates an annual savings between $600,000 and $1 million, and projects that the Air Force will save $400,000 in supplemental funds.
