SEWAGE. Any or all of the following: human excreta; food wastes disposed of through sewers;
wash water; liquid wastes from residences, institutions, business buildings and industrial
establishments and such diluting water as may have entered the waste disposal system, or the water
carried waste products or discharge from human beings or other wastes from residences, public or
private buildings.
SEPTIC 'rAN K. A watertight receptacle which receives the discharge of a building sanitary drainage
system or part thereof, and is designed and constructed so as to separate solids from the liquid,
digest organic matter through a period of detention, and allow the liquids to discharge into the soil
outside of the tank through a system of open joint or perforated piping, or a seepage pit.
CESSPOOL. A lined and covered excavation in the ground which receives the discharge of domestic
sewage or other organic wastes from a building, so designed as to retain the organic matter and
solids, but permitting the liquids to seep through the bottom and the sides.
WATER CARRIED SEWAGE DISPOSAL SYSTEM. Includes all piping, septic tanks, seepage
systems, seepage pits, cesspools, treatment plants, or other devices through which household wastes
are conveyed with the aid of water. It does not include the mains, treatment or disposal systems of
publicly owned sewer systems nor the collector portions of privately owned sewer systems.
SUBSURFACE DISPOSAL FIELD. A system of buried open-jointed pipes through which septic
tank effluent may seep or leach into the surrounding porous soil.
SEEPAGE PIT. A covered pit with open-jointed lining through which the septic tank effluent may
seep or leach into the surrounding porous soil.
NON-WATER CARRIED SEWAGE DISPOSAL SYSTEM. All devices used for the disposal of
human excreta in which water is not used as a conveyance.
SAN!TARY SEWER. Any publicly owned sewerage system incorporating either a salt-water outfall
or a sewage treatment facility, which operated by a political subdivision of the State of Alaska or by
virtue of a Certificate of Convenience and Necessity issued by the Public Service Commission of the
State of Alaska, providing, however, that such sewerage system meets the requirements of the
Alaska Department of Health and Welfare and the Greater Anchorage Area Borough Health

public need. In order to establish the aforementioned conditions, all mandatory connection orders
to certificated, privately owned public sewerage systems shall be subject to automatic review by the
