In 2011, the City of Phoenix commissioned their first aquifer storage and recovery (ASR) well. Sophisticated logic programming was incorporated to reduce costs associated with management, operation, maintenance, and regulatory reporting. This presentation will detail the programming concepts used to reduce costs, and outline benefits relating to increased well operation efficiencies. This session is a predecessor to Gary Gin’s (R.G., City of Phoenix) presentation titled “City of Phoenix, Aquifer Storage and Recovery Well #299: ‘How Did You Unclog That Well?’ Radial Injection Surge Development”.
