8.32.110 - Definitions.¶
Unless otherwise specially provided, or required by the context, the following terms have these meanings in this division. "Community sewer collection system" means the structures, devices, equipment and appurtenances intended for the collection, transportation and pumping of sewage from two or more structures to a treatment or disposal facility. "Domestic water supply reservoir" means an existing or proposed open uncovered reservoir used or intended to impound water for human consumption or domestic purposes, including a planned reservoir
where the water impounder states in writing to the City Council his or her intent to install or construct it, and satisfies the City Council that he or she has appropriate rights in the land and the ability to finish and maintain it. "Drainage area" of a domestic water supply reservoir means all the land that can or may drain into the reservoir, whether or not the topographical configuration is artificially or naturally caused. "Health Officer" includes any subordinate(s) that the Health Officer designates from time to time to perform any or all of the Health Officer's functions hereunder. "Improper functioning" individual system means a system which allows sewage to escape to the surface of the ground or prevents plumbing fixtures from draining. "Individual system" means a system which consists of: (1) the drainage pipes of a structure and the septic tank and subsurface absorption system to which they are connected; or (2) any alternative system designed for the disposal of sewage and acceptable to the Health Officer. "Sanitary sewer" means a system for collecting residential or municipal wastewater and directing the collected wastewater to a treatment works prior to disposal. "Sewage" means liquid or solid waste substance, which is associated with human habitation or which contains or may be contaminated with human or animal excrement or offal. "Sewer availability" means a sanitary sewer is available for connection to a structure requiring sewage disposal because: 1. The entity operating the sanitary sewer indicates in writing that the proposed structure can be connected to the sanitary sewer; and 2. The cost of providing sanitary sewer service, exclusive of all annexation fees, connection fees, and the sewer pipe installation costs between the structure and the publicly owned sewer in the street or right-of- way, is less than five thousand dollars ($5,000.00), or ten percent of the full market value of all existing and proposed improvements, whichever is greater; and a. The area of property to be served is less than forty thousand (40,000) square feet and the sanitary sewer is less than three hundred (300) feet, measured horizontally, from the nearest property boundary, or b.

"Site evaluation" means the investigation of a subdivision or a lot to determine the feasibility of installing an individual system. It shall include a determination of compliance with all applicable sanitation requirements and a sanitary survey of the area. Should the sanitary survey disclose failing individual systems in the immediate vicinity of the site evaluated, this shall be cause for denial of the feasibility of installing an individual system. "Subdivision" means a division or any use of real property that does or may reasonably be expected to generate sewage or require sewage disposal; and "subdivider" means the owner of or applicant for a subdivision.

B. Upon written application to the Health Officer and in only those cases where an existing individual system is found to be functioning improperly, the requirement for connection to the sanitary sewer may be waived by the Health Officer if the Health Officer finds: 1.

If the parcel or lot is between fifty (50) and one thousand (1,000) feet from the reservoir or tributary stream, a watertight sewage holding tank system, or equal will be required. Such system must be owned or operated by a presently existing public agency having statutory authority to provide such service. 2. Beyond one thousand (1,000) feet from a reservoir or tributary stream an individual system or other similar acceptable system may be permitted subject to all the conditions specified in Section 8.32.200.
