This post was last edited by hgm on 2024-8-16 at 10:27. For plumbing systems, FRD stands for initial rainwater, DW for domestic water, and SW for domestic wastewater. What are the full English spellings of these three abbreviations? Thank you
In water supply and drainage pipelines: – FRD usually stands for Fire Drainage, which is used for draining water in fire protection systems. - DW stands for Dirty Water or Domestic Wastewater, and is primarily used for discharging domestic or household wastewater. - SW stands for Storm Water, which is used to drain rainwater. .
SW – service water; DW – demineralised water; DS – domestic sewage; PW – potable water; RW – rain water
FRD refers to initial rainwater; it’s probably not what the guy upstairs said: FRD usually stands for Fire Drainage, which is used for draining water in fire protection systems
