Overview:<\/h3>\n

The City of Pueblo, Colorado is located at the confluence of the Arkansas River and Fountain Creek, 112 miles south of Denver, Colorado. With a population of over 160,000 people in its Metropolitan Statistical Area, it ranks ninth among Colorado cities.<\/p>\n

The Test Site location is at the Nature & Wildlife Discovery Center, located in Rock Canyon along the banks of the Arkansas River. The mission of the Center is to provide unique experiences in education, conservation and recreation in environmental stewardship. In 2016, the Raptor Center admitted 372 raptors and released 100 back into the wild.<\/p>\n

The test site selected at Pueblo Nature and Raptor Center is a Wet-Well (Lift Station). The wet well contains two digester pumps (Lead and Lag pumps) to maintain levels in the wet well from 2.2 feet to 3.2 feet. The current controller (DigiGauge 2300) uses a problematic Bubbler system (Differential Pressure) for level feedback used to control the pumps to maintain programmed levels. Since this site is designed to run autonomously, for redundancy, a mechanical float system is in place at over-alarm height and low-well alarm levels that will send an alarm to the office if they are detected.<\/p>\n

The current controller in addition to the bubbler system has a 4-20mA input. A Laser Tech (LTI) TruSense\u00ae<\/sup> S330<\/a> will be used to replace the bubbler system for level measurement input in the water treatment plant.<\/p>\n

There are 4 objectives for this beta site: 1) integration to existing standalone controllers, 2) ease of setup, 3) sensor data collection for later evaluation and 4) environmental operation.<\/p>\n

System Components<\/h4>\n

The reason for this system is to collect wastewater from the park and park restaurant, then lift the wastewater to be processed. Current system components are two digester pumps, DigiGage controller (Bubbler system feedback), remote cellular system, and a mechanical float system as a backup level control.<\/p>\n

The Wet-Well dimensions are approximately 8 feet in diameter and 10.5 feet deep. There are three pipes that drain into the Wet-Well from the park\u2019s facilities. See photo 1<\/p>\n

Critical Set Points<\/h4>\n

The objective is to allow the wet well to fill to a predefined height and then lift the wastewater from the wet well to be processed. To prevent the pump(s) from running dry, when the level gets down to a predefined level the pump(s) should turn off. During normal pump-down operations, only one pump (Lead pump) is required. The second pump (Lag Pump) is used during high-demand effluence filling.<\/p>\n

If the system moves out of bounds of the control levels for any reason, there are Over and Under alarm points. Once a critical alarm level has been detected, the cellular system will phone home to alert that a critical level has been met.<\/p>\n
