epVAC.VIS, the Combined Black and Gray Water Systems
-
In the combined black and gray water networks epVAC.VIS, the liquid flows by gravity from baths, sinks, bidets and floor drains to the valve package/Auxiliary Collection Basin ACB. Liquids & solids from toilets flow under vacuum directly to the Combined Vacuum Power Pack CVPP. The jointly collected and transferred wastewater is either disposed to the public sewer lines or to the treatment plant for reuse.
