Administration & Control
The existing Administrative Building was completely renovated during plant expansion in 1997. The new building has office space for plant personnel, a control room, conference room, laboratory, locker room, laundry room, and garage.
Control Room
The administrative building houses a Programmable Logic Controller (PLC) network computer to which all critical pieces of equipment are linked. From the computer terminal, it is possible to monitor the equipment as well as make operational changes. The PLC network computer also has the capability to monitor equipment hours. The entire system is linked with an auto-dialer alarm system, which in the event of a malfunction at the plant during off-hours, will send an alarm to personnel on call.
Laboratory
The laboratory is a fully equipped modern facility. To monitor plant performance as well as process control, the laboratory routinely performs testing on a wide variety of parameters. Mandan’s North Dakota Pollutant Discharge Elimination System (NDPDES) permit requires daily monitoring of pH and temperature and biweekly effluent monitoring for Biochemical Oxygen Demand, Total Suspended Solids, Ammonia, Phosphorus and E. coli. In addition, the permit requires a monthly grab for Total Kjeldahl Nitrogen and Total Nitrite/Nitrate as Nitrogen. Quarterly monitoring of Whole Effluent Toxicity and yearly effluent monitoring of metals, cyanide, phenols and general chemistry are required. Mandan’s laboratory is certified by the North Dakota Department of Health. The Extended Aeration Activated Sludge Treatment System (EAASTS) is treating the wastewater so effectively that it is hard to tell the difference between potable water and wastewater effluent.
Generator
The wastewater treatment plant is equipped with an emergency backup generator. The generator is powered by a 749 hp, 500KW Model 3412 Caterpillar 12-cylinder diesel engine. The generator is designed to supply full load capability within 10 seconds after detecting a power outage or failure. The generator will supply power to the wastewater plant while monitoring the utility supply line for uninterrupted power.
Personnel
The wastewater treatment plant is staffed with a superintendent, an assistant superintendent, a laboratory technician and two operators. Normal hours are Monday through Friday 8 a.m. to 4:30 p.m. with one person on call every week for after hour emergencies. The person on call comes in on weekends and checks the plant, making sure that all equipment is working properly. The assistant superintendent, laboratory technician and operators all report to the plant superintendent. The plant superintendent in turn answers to the city engineer.
