    Can the floor drain in a pump house discharge to grade or must it be connected to a sanitary system? The pump house is for the fire suppression system fire pumps.

    I did not see anything in the code allowing it or prohibiting it.

    Thanks.

    I'm not sure about the code for that but I've seen it many times especially in sprinkler rooms like you mentioned.

    DRAIN. Any pipe that carries waste water or water-borne
    wastes in a building drainage system.

    PLUMBING FIXTURE. A receptacle or device that is connected
    to a water supply system or discharges to a drainage
    system or both. Such receptacles or devices require a supply
    of water; or discharge liquid waste or liquid-borne solid
    waste; or require a supply of water and discharge waste to a
    drainage system.

    SECTION 412
    FLOOR AND TRENCH DRAINS

    As floor drains are specifically covered in Ch. 4 I would say they are a fixture....

    IPC 802.1.5 & the exception to 802.2 imply that clear-water waste doesn't have to be connected to the sanitary sewer. Some sanitation authorities don't want clear-water waste entering their sewers.

    What is the water picking on it's way into the floor drain? Oils? Dirt? Doesn't sound like clear water anymore...

    I have a similar question with regards to rainwater collection not being allowed to be retained in a cistern with a pump for later yard use, what say you?

    House is at a lower elevation than the rear of the property. Need a pump to move collected water up hill, but city is concerned about using the collected water over an extended period between rains.

    Why would the city care how you use the water you collect as long as you don't discharge into their system. To me it sounds like a great idea from both sides of the coin.

    Concerned how? Pumping during a rain event? Not pumping during a rain event? Cistern contents going septic between pumping events?

    Not a great idea to dump water from a fire pump house into a sanitary sewer as you greatly increase the fixture count because most fire pumps have an open cooling system - i.e. water runs thru fire pump to cool engine and is discharged onto the floor or trench drain for disposal . It would easily require an 6 to 8 inch pipe just to handle the fire pump runoff - we usually discharged into the retention pond and required some sort of oil/ water skimmer near the discharge point.
