Water is a critical natural resource for this U.S.-based international healthcare corporation because it is used extensively in both the manufacturing and sterilizing processes. The company's environmental, health, safety and sustainability policy drives programs that reduce environmental impacts, including those related to water use and wastewater discharges. To meet the EPA’s National Pollutant Discharge Elimination System (NPDES) compliance they needed to address issues around chlorides and total dissolved solids from their water softeners.
The company had previously collected and provided treatment for all industrial and domestic wastewater generated at one of its plants in the Midwest. The cost and maintenance for a more advanced onsite treatment system was found to be cost prohibitive. Stanley Consultants was called in to help find a solution to the NPDES violations. Stanley engineers prepared a study that was the basis for the client's decision to modify the treatment facility and connect to a public treatment facility.
To transfer the partially treated wastewater to the public system, it was necessary to construct a duplex submersible wastewater pumping station with metering and sampling facilities, 1,200 feet of 6-inch force main pipeline and 1,500 feet of 10-inch sanitary sewer lines. Stanley Consultants provided engineering design to incorporate the client's system into the municipal system.
Project features included detailed instrument and control plans, smart water communications, full multi-discipline engineering and redundant force main design.
