Can jockey pump be used as potable water pump?
(OP)
I am working on a project which involves multiple facilities. We have a water tank and a pump room on site. Our client needs only one single water line in the site which will be common to both fire water and potable water. At every building inlet point, there are 2 lines entering the building, one for potable water and other for fire water. Can anyone tell me is it okay to go with this.

not sure about using a jockey pump.
But the set up you are proposing is kind of like a city water main, where you tap for domestic and fire.

Stookeyfpe has the right answer but did not give the reason. A jockey pump is to eliminate undue tripping of the sprinkler alarm check valve if the municipal water pressure fluctuates widly.
How about maintain pressure on a system with a fire pump so the fire pump does not run , unless needed.

What equipment is proposed to be in the pump room?
Will each facility have its own skid mounted fire pump?
What are the requirements of your AHJ?

The way I understand it is a jockey pump, the way we are used to seeing it anyway, isn't required.
From the 2013 handbook
As one example of where a jockey pump would not be needed is when a flow test in the hills of West Virginia produced 120 psi static, 30 residual @ 600 gpm but the project required a density of .25/3,900+500 hose.
Obviously the public water wouldn't do the job but from a tank with a 100 psi pump we could use the domestic water to maintain pressure.
