The following definitions apply in this chapter:

Alteration means expansion or change in location of an existing system or any part of it. Major alteration is the expansion or change in location of the soil absorption facility, treatment unit, or any part of it. Minor alteration is the replacement or relocation of a septic tank or other components of the system other than the soil absorption facility, or a change in distribution technique or method.

Biochemical oxygen demand (BOD) means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure, five days at 20 degrees centigrade expressed in terms of weight and concentration (milligrams per liter (MG/l).

Building drain means that part of the lowest horizontal piping of a drainage system which receives the discharge from soil, waste, and other drainage pipes inside the walls of the building and conveys it to the building sewer, beginning five feet (one and one-half meters) outside the inner face of the building wall.

Building sewer means the privately owned sewer line in two parts. First part, a building sewer “lateral” wholly contained on private property, which is the line extending from the building drain to the edge of the private property boundary; second part, the sewer “stub out,” which is the line extending past the edge of private property boundary into the public rights-of-way up to where it connects to the public sewer. “Stub-outs” are wholly contained within public rights-of-way. Building sewers include not only sewer lines on private property, called “building sewer laterals,” but also includes the sewer “stub-outs” within rights-of-way up to the point where the line connects with a public sewer main. “Building sewer laterals” and “sewer stub-outs” are not part of the public sewer, and are not owned by the City, even if located in rights-of-way.

Garbage means solid wastes from the domestic and commercial preparation, cooking and dispensing of food, and from the handling, storage and sale of produce.

Natural outlet means any outlet into a watercourse, pond, ditch, lake or other body of surface or groundwater.

Neighborhood extension project (NEP project) means design and construction of a public sewer to provide public sewer service to existing properties served by on-site septic systems within the City limits as shown on the City of Bend Comprehensive Plan Map at the time of the urban growth boundary expansion by Ordinance No. 2271, effective on acknowledgment on December 6, 2016. It does not include extension of public sewer to existing property within urban growth expansion areas, which are governed by annexation agreements and/or City codes related to new annexation areas.

Private on-site septic system means an individual residential or other property on a septic system or any private sewer system (i.e., drill holes, mounded sand beds, etc.) within the City limits.

Public sewer means any sewer main owned and controlled by the City. A building sewer is not a sewer main and is not a public sewer.

Repair means installing all portions of a system necessary to eliminate a public health hazard or pollution of public waters a failing system creates. Major repair is replacing the soil absorption facility, treatment unit, or any part of it. Minor repair is replacing a septic tank, broken pipe, distribution unit, or any part of the on-site system external to the septic tank or treatment facility except the soil absorption system. Unless classified as a major repair or major maintenance, any replacement of a part of a system with a part that does not meet the original design specifications is a minor repair.

Sanitary sewer means a sewer which carries sewage and to which storm, surface and groundwaters are not intentionally admitted.

Sewage means the water-carried wastes from residences, business buildings, and institutions.

Sewage treatment plant means any arrangement of devices and structures used for treating sewage.

Sewage works means all facilities for collecting, pumping, treating and disposing of sewage.

Sewer means a pipe or conduit for carrying sewage.

Slug means any discharge at a flow rate or concentration which could cause a violation of the discharge standards of this code or any discharge of a nonroutine, episodic nature including an accidental spill or a noncustomary batch discharge.

Storm sewer means a sewer which carries storm and surface waters and drainage, but excludes sewage and industrial wastes, other than unpolluted cooling water.

Suspended solids means a total suspended matter that floats on the surface of, or is suspended in, water, wastewater or other liquids, and which is removable by laboratory filtering.

Watercourse means a channel in which a flow of water occurs, either continuously or intermittently. [Ord. NS-2360, 2020; Ord. NS-2320, 2018; Ord. NS-2182, 2012; Ord. NS-2146, 2010]
