Examples of sources of domestic septage include septic tank wastewater, grey water or wastewater generated from sink drains, lavatories, showers, dishwashers, and residential laundries.

Septic Tank: a water-tight covered receptacle designed to receive and process the sewage discharge from a building. The effluent from the septic tank is distributed for disposal through the soil. Settled solids and scum from the tank are pumped out periodically and hauled to a treatment facility.

Grey water: wastewater generated from sink drains, lavatories, showers, dishwashers, and laundries – usually associated with a vessels CHT system. It does not include industrial wastes, infectious wastes or human body wastes. Grey water is not an acceptable description for wastewater discharge to an HRSD Treatment Plant; the waste hauler must specify the source of the grey water (i.e. from a CHT system).

Domestic Holding Tank: a system utilized on portable offices/trailers, typically at temporary locations where there is no direct sanitary sewer connection, for collection of both domestic sewage and grey water. It does not include industrial wastewater.

Fats, Oils, and Grease (FOG) shall mean floatable fats, oils, grease and settled solids produced during food preparation that are recovered from grease control devices; passive devices which stop FOG from entering the sanitary sewer system.

HRSD does not accept yellow grease. Yellow grease shall mean kitchen cooking oil used in food preparation that has not been in contact with or contaminated with other material such as water, wastewater, or solid waste. 

A facility including pumps and equipment for pumping fluids from one place to another. Only liquids and floatables from pump stations may be discharged at HRSD plants (sludge is prohibited). 

A toilet that is not connected to a sewage system but has a compartment utilized as temporary storage of domestic sewage. 

Any combination of domestic septage, portable toilet or CHT wastewater. HRSD does not accept mixed loads containing grease.

A wastewater collection, holding and transfer (CHT) system on many ships/boats, designed to collect both domestic sewage and grey water, until the wastewater can be pumped off and hauled to a suitable shore receiving facility. It does not include industrial or bilge wastes.

Those wastes which are pumped from a public or private pump station and subsequently discharged into a downstream sanitary sewer access point. Generally, pump arounds are performed when there is a pump station malfunction or maintenance is being performed. 
 
Pump-around discharges are generally handled under the direction of the locality where the work is being performed. Prior approval from HRSD’s P3 Department is not required if the pump-around occurs in the field and no wastewater is hauled to HRSD.
