Potable water system for Motel

Potable water system for Motel

Potable water system for Motel

(OP)
Our office has a project which involves designing a potable water supply for a 74 room 3 story motel. I can total up the usage per fixture based on the state code no problem. But not every room will be filling the tub and flushing the water closet at the same instant. It seems that there should be a diversity factor for determining actual maximum flow rate simular to designing for power usage. Our state code has no mention of such a factor. Is there a rule-of-thumb which I could use?

RE: Potable water system for Motel

Leastwise it is a potable water system... First time i saw the title I read it as a "portable water system for a hotel ......

Frankly, I'd read the guidelines above, then check into three local hotels of a comparable size and ask the manager if you could look at his utility room in each.

Get his feedback on access, what often breaks, what he would recommend changing, and what problems he has had with guest complaints. Compare "Regular" service, weekend/football or concert service when all the nearby hotels are also fully booked, and convention/large meeting service when he/she has lots of guest all waking up at the same time.

RE: Potable water system for Motel

racookpe brings up something that occurred to me, depending what kind of 'event' might be going on there may be use cases where a lot of the rooms will at least be showering/bathing at a similar time.

Pretty sure one hotel I stayed at once ran out of hot water, presumably because of excess demand due to synchronized guest schedules.

RE: Potable water system for Motel

Running out of hot water at the hotel has happened to me more than once when on a business trip. When it happened it was at the 7:00 to 7:30 time frame. Now I take my showers at 5:30 to 6:00.

Check the Grundfos pump site - they more than likely have everything you need including the pumps.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: Potable water system for Motel

I find that residents in hotels often have similar schedules. Usually the internet is completely bogged down from 6pm-9pm when business travelers are back from work. Try the internet in the middle of the day or night, when less people are using it, and it is often good quality.
