Sanitation Agency Installs Biological Aerated Filters To Meet Strict Discharge Limits

摘要

Nestled in the scenic Lake Tahoe region of eastern California's Sierra Nevada Mountains, the Tahoe-Truckee Sanitation Agency (TTSA) faces some of the most demanding discharge limits in the country. TTSA operations are complicated, as regional water temperatures range from 7℃ to 20℃ (44℉ to 68℉), and the population jumps from 35,000 permanent residents to more than 100,000 vacationers during weekends and holidays, causing huge load variations. The agency is located on Lake Tahoe's north shore, near numerous ski resorts and golf courses.
