Week 11

Question 1

A device for receiving the discharge of a waste pipe or pipes and discharges them by gravity into the sanitary drainage system Waste receptors include but are not limited to, floor drains, floor sinks, trench drains, hub drains standpipes, mop basins service sinks, and laundry trays

Answer 1

WASTE RECEPTOR

Question 2

A tank or pit that receives sewage or liquid waste, located below the normal
grade of the gravity system and that must be emptied by mechanical means.

Answer 2

SUMP

Question 3

An automatic water pump powered by an electric motor for the removal
of drainage except raw sewage, from a sump, pit or low point.

Answer 3

SUMP PUMP

Question 4

A vent from pneumatic sewage ejectors, or similar equipment, that
terminates separately to the open air

Answer 4

SUMP VENT

Question 5

A device for lifting sewage by entraining the sewage in a high- velocity jet of steam, air or water

Answer 5

SEWAGE EJECTOR

Question 6

A device installed upstream from the interceptor having an orifice that controls the rate of flow through the interceptor and an air intake (vent) downstream from the orifice that allows air to be drawn into the flow stream.

Answer 6

FLOW CONTROL (VENTED)

Question 7

A device designed and installed to separate and retain for removal,
by automatic or manual means, deleterious, hazardous or undesirable matter from normal wastes, while permitting normal sewage or wastes to discharge into the drainage system by gravity

Answer 7

INTERCEPTOR

Question 8

A plumbing appurtenance that reduces nonpetroleum fats, oils and greases in effluent by separation or mass and volume reduction

Answer 8

FATS. OILS AND GREASES (FOG) DISPOSAL SYSTEM

Question 9

Plumbing appurtenances of not less than 500 gallons (1893 L) capacity that
are installed in the sanitary drainage system to intercept free-floating fats, oils and grease from wastewater discharge. Separation is accomplished by gravity during a retention time of not less than 30 minutes

Answer 9

GRAVITY

Question 10

Plumbing appurtenances that are installed in the sanitary system to intercept free-floating fats, oils and grease from wastewater discharge.
Continuous separation is accomplished by air entrainment, buoyancy and interior baffling

Answer 10

Hydromechanical
