Pomona Valley Hospital Medical Center, which is staffed by about 800 physicians and twice as many nurses, is a 437-bed hospital that relies on 7 sewage ejection pits to collect waste from the hospital complex. These sewage ejection pits were responsible for pumping the waste material out of the buildings and into the municipal sewer system. Like many other hospitals across the U.S., they were having problems with “disposable” wipes.
Cabell Huntington Hospital is a regional, 300-bed medical center and teaching hospital in Huntington, West Virginia. It has more than 400 physicians and 1,000 nurses; patient admissions exceed 23,000 per year.The Challenge
Cabell Huntington’s main building is heated by two 100-pound steam boilers. Three times a day, the maintenance staff begins its shift with a “blowdown” on each boiler—purging the boiler’s water lines to remove calcium chloride and other suspended solids and minimize the buildup of scale. The boilers are refilled with clean water and run for about eight hours until an operator on the following shift opens the valves for the next blowdown.
Water drained from the boilers is very hot—around 200 degrees Fahrenheit. It’s blown to a roughly eight-foot-deep-by-four-foot-square pit, where it’s mixed with cold water and eventually pumped out through the hospital’s sewage lines.
