GLENN HANSON, P.E.
B.S., Electrical Engineering
University of Illinois
Professional Engineer: Tennessee
Glenn provides power distribution, motor control, instrumentation, control and logic development. He is knowledgeable of programming programmable logic controllers (PLC’s), and Operator Interface systems and software. While working with LDA, he has been involved with designing water and sewage pump stations as well as water and wastewater treatment facilities. The design scopes have ranged from power and control to instrumentation, SCADA, telemetry, and PLC’s.
OLD MILL DISTRICT UNDERGROUND ELECTRIC CONDUIT & STREET LIGHTING PROJECT, PIGEON FORGE, TENNESSEE (2014-2015)
Glenn prepared the design to relocate the above ground utilities including electrical power, telephone, and cable TV lines to underground. This included the required conduit routing and pull box location to best navigate through the maze of utility piping for water, sewer, and gas that was already underground. New decorative street lighting was also powered by underground wiring.
Glenn prepared design documents for a new SCADA system for the Morristown Utility Commission wastewater pumping stations. The project included system design and specifying equipment for a PLC based pump station monitoring system for 35 existing pumping stations. The SCADA system included monitoring of pump run status, alarm conditions, wet well level and alarms, and status and alarm conditions for other equipment on the sites including communicators, generators, odor control chemical feeders, etc. The system was designed to communicate to the water treatment plant via fiber optic modems where fiber was available. Remote sites communicate via cellular modems.
The plant improvements made on this project included the upgrade and replacement of the entire electrical power distribution system as well and the control system. Glenn designed the underground routing of the power, control, and instrumentation wiring utilizing a combination of existing duct bank, new duct bank and new direct buried electrical trenches. The underground routing was utilized between several buildings, wet wells, and the larger outdoor equipment.
He prepared the electrical, instrumentation, and control designs for a new water booster station and elevated storage reservoir. The project consisted of a 500 gpm (expandable to 1000 gpm) booster station which pumps to a 250,000 gallon elevated storage tank. The booster station included VFD driven pump motors, emergency generator, and extensive monitoring of pump, motor, station environmental conditions, and site security equipment, all transmitted via SCADA to the KUB water treatment plant. Pump operation is based on the water level in the new reservoir, which includes instrumentation to monitor water level, chlorine residual, site security equipment, and the status of the FAA required lighting equipment. All information is transmitted back to the WTP via SCADA. The project design was fast-tracked due to the construction schedule for a student housing project.
WASTEWATER SYSTEM REHABILITATION PROGRAM & EQUALIZATION BASIN SYSTEM, OAK RIDGE, TENNESSEE (2013-2016)
For this project three equalization basins were designed to collect and store wastewater during periods of high flow. The project included pump stations, automated valve stations, and flow monitoring stations that were used to automated and control the EQ system. The control system was designed to automatically direct wastewater to the EQ basins when downstream flow conditions exceed the designed flow capacity. Later, when downstream flow conditions decreased below the system capacity, the stored wastewater in the EQ basins would be returned to the system and delivered to the plant for treatment. Glenn provided the electrical design of the various pump, valve control, and flow monitoring stations. He also designed the control system to automate the process. The EQ control system consists of four remote controllers, flows monitored at three remote locations, and the main controller at the main wastewater treatment plant. Communication between the remote location and the main was accomplish via Ethernet on the city’s fiber optic network. The main controller was tied into the existing WWTP main operator control computers.
WASTEWATER SYSTEM IMPROVEMENTS - WWTP & SPRING CREEK EQUALIZATION BASINS & SPRING CREEK PUMP STATION REHABILITATION, MORRISTOWN, TENNESSEE (2016)
Glenn provided the electrical, instrumentation and controls design for the two EQ basin pumps stations and the rehabilitated wastewater pump station. The EQ basin controls were designed to store wastewater during periods of high flow and then return the stored wastewater to the system for treatment when the system capacity would allow. The control pump stations were connected to the main wastewater SCADA system via the city’s FIBER-NET system.
