If there is a sink and a tap, it has to be potable because somebody could fill a cup.
That might be a key point here. Did the RFP from Amtrak, Caltrans and the midwestern states actually state that "potable" water be provided or was it just assumed?
From the RFP:
15.0 Water and Waste System
A pressurized fresh water system shall be provided on each car to supply potable water for drinking, hand washing, toilet flushing and Café car galley requirements. Storage for 200 gal (757 L) of potable water shall be located in the A/F-end or B-end equipment room of coach and
cab/baggage cars, and 300 gal (1135 L) on café/lounge cars. A re-circulating chiller shall provide chilled potable water to two dispensing stations, one on each level of all cars.
A vacuum type waste retention system shall be provided on each car. The waste tank, drain lines and associated components shall be located in the B-end equipment room. Gray water from toilet room and galley hand washing sinks shall be captured and pumped to the waste
No waste water shall be permitted to drain to ground, including gray water from hand washing sinks. Only fresh water from the following sources shall be permitted to drain to ground:
x Condensate from Heating, Ventilation and Air Conditioning (HVAC) and chiller units
x Drain from potable water chillers
x Melt water from ice storage bins
x Carbody drains from door tracks and equipment rooms
x Fresh water from water supply system when drained manually or by freeze protection devices
All car types shall have an Accessible Toilet Room (ATR) on the lower level. Coaches and cab/baggage cars shall also have a Unisex Toilet Room (UTR) on the upper level.
The water and waste systems shall be protected from damage due to freezing through the use of heat tape, blanket heaters, automatic drain valves (water system only) and insulation.
See Chapter 14, Food Service, for galley water system requirements.
Further in 15 it requires stainless piping and fittings.
Chapter 14 stated potable for the coffee maker and hand washing sink in the food prep area.
Chapter 19 stated all materials used in food preparation areas of the café-lounge car, potable water systems and trash storage shall be certified to meet all applicable Public Health Service sanitation requirements.
There's no actual mention of lead except as a prohibited material for brake shoes, but seeing as it's been an compliance issue here in water supply lines for 50 years, I'm guessing that lead-free supply and storage is assumed by any US based fabricator....
