NORMAL SEWAGE
Sewage, industrial wastes or other wastes which, when analyzed, show, by weight, the following characteristics:
(1) 
BOD: 2,000 pounds per million gallons (240 milligrams per liter) or less.
(2) 
Chlorine demand: 208 pounds per million gallons (25 milligrams per liter) or less.
(3) 
Suspended solids: 2,500 pounds per million gallons (300 milligrams per liter) or less.
OTHER WASTES
Garbage (shredded or unshredded), refuse, wood, eggshells, coffee grounds, sawdust, shavings, bark, sand, lime, cinder, ashes and all other discarded matter not normally present in sewage or industrial wastes.
PERSON
Any individual, firm, company, association, society, corporation or group.
pH
The negative logarithm of the hydrogen ion concentration in moles per liter. It indicates the intensity of acidity and alkalinity of the pH scale running from 0.0 to 14.0.

SANITARY SEWAGE
Sewage discharging from the sanitary conveniences of dwellings (including apartment houses and hotels), office buildings, factories or institutions and free from stormwater, surface water, industrial wastes and other wastes.

SEWAGE WORKS
All facilities for collecting, pumping, treating and disposing of sewage.
SEWER
A pipe or conduit for carrying sewage.
SLUG

STORM DRAIN (SOMETIMES TERMED "STORM SEWER")
A sewer which carries storm- and surface waters and drainage, but excludes sewage and industrial wastes other than unpolluted cooling water.
SUPERINTENDENT
The Commissioner of Public Works of the City of Rensselaer or his authorized deputy, agent or representative.
SUSPENDED SOLIDS
Solids that either float on the surface of or are in suspension in water, sewage or other liquids and which are removable by flotation, skimming and sedimentation.

WATERCOURSE
A channel in which a flow of water occurs, either continuously or intermittently.
