STP, WWTP, PCP?

Also common in PA, USA: WPCF - Water Pollution Control Facility
I also have no idea why, I have never noticed a discernable difference between a Sewage Treatment Plant, Pollution Control Plant, Wastewater Treatment Plant or a Water Pollution Control Facility. I've never seen Wastewater Treatment Works or Sewage Treatment Works.

STW and WWTW must be a UK thing.

The names make the facility more appealing to the politicians. They all treat sewage.

Now I'm really confused...
By sow's logic, the liquid which enters a factory's Pretreatment plant is Wastewater, then it becomes Sewage once the effluent enters the municipal lines? Or is it still Wastewater? Is the other liquid in that same line Wastewater or Sewage? Do we call the receiving POTW a WWTP or an STP, or do we play it safe and call it a WPCF?
Women and cats will do as they please; men and dogs should just learn to live with that - Steve

Wastewater is a result of the plant process.
Sewage is what goes into the municiple water treatment facilities.
If wastewater is to go into municiple sewage, it must meet certain criteria.
If wastewater is to go into a well (which is what we do a lot of), it must meet a different set of criteria from municiple.
A lot of sites have both sewage and wastewater flows. Sewage sources would be like surface run-off, washroom effluent, etc. Wastewater comes from the process usually.

you may call your wasted water "wastewater" and you may treat your "sewage" in a "water" treatment facility, but that terminology is completely twisted around for this region of the sphere...
here - all fluid (and solids) going to the POTW (aka stp, wwtp etc.) are called waste water. Often, there is pre-treatment of industrial wastewater, before accepting into the publicly owned sewer system. This is determined by the owner of the sewer system and is a permit requirement for connection to the system. Generally the treatment facility is a "wastewater" treatment facility. And for convenience, all lines are called sewers. Even the storm drains are often called storm sewers, therefore implying that they carry sewage. Alternatively, a "water treatment" facility is used for filtration and chlorination or other necessary treatment of river water for use as potable water.
