The purposes of this chapter are:
A. To provide for operation and maintenance of the city's sewer system in a reliable and serviceable condition;
B. To eliminate or minimize sanitary sewer overflows by eliminating or minimizing stoppages and reducing sources of inflow and infiltration into the city's sewer system;
C. To comply with applicable legal requirements pertaining to the city's sewer system;
D. To protect the public health and safety by establishing and providing a mechanism for enforcing performance standards for private sewer laterals that connect or are connected to a public sewer main; and
E. To comply with the goal of the city's Sewer System Management Plan which was adopted at the request of the State Water Resource Control Board, and to maintain all parts of the sewer system and reduce and prevent sanitary sewer overflows. (Ord. 2012-02 § 1 (part), 2012)
As used in this chapter, regardless of case, the following words, phrases and terms shall have the following definitions.
A. AIR TESTING or AIR TESTED. A method whereby a building sewer lateral is pressurized with air for the purpose of detecting leaks or defects in the pipe being tested. An air tested building sewer lateral will be deemed defective for purposes of this chapter if it does not hold three and one-half (3.5) pounds per square inch of air pressure (psi-air) for at least two (2) minutes with at least two and one-half (2.5) psi-air remaining at end of the air test.
B. BACKFLOW PREVENTION DEVICE. Includes, but is not limited to, backwater overflow devices, backwater check valves, pressure relief devices, shutoff systems, and any other devices the city may approve for the purpose of preventing or minimizing the possibility that raw sewage will back up into any structure or for any similar purpose.
C. BUILDING DRAIN. That part of the lowest piping of a building drainage system which receives the discharge from soil, waste and other drainage pipes within the building or structure and conveys it to the building sewer lateral. The point of connection of the building drain to the building sewer lateral shall be within two (2) feet of the outside of the building wall. A clean-out and backflow prevention device shall be installed at the point of connection of the building drain to the building sewer lateral.
D. BUILDING SEWER LATERAL. That part of a drainage system which extends from the end of the building drain and conveys discharge to a public sewer or other point of disposal. The building sewer lateral shall terminate at the wye or other manufactured connection to the public sewer.
E. BUILDING WALL. The exterior component part of a structure built, erected, framed and designed for the housing, shelter, enclosure or support of persons, animals, or property of any kind.
F. CERTIFICATE OF COMPLIANCE. A written certificate issued to a property owner by the Public Works Director or his/her designee certifying that a building sewer lateral is properly equipped, structurally sound and complies with all standards established by the city.
G. DEFECTIVE SEWER LATERAL. Any building sewer lateral that displays leaks or defects upon the completion of inspection or that is deemed by the city, in its discretion, to be defective upon completion of air testing or any other testing method required by the city.
H. INSPECTION. A process whereby both a video camera and/or smoke are placed into and run through the inside of a building drain, building sewer lateral or public sewer for the purpose of detecting leaks or other obvious defects.
I. MANUFACTURED CONNECTION. A commercially manufactured and available sewer "wye" or "tee" fitting of the proper size and material for the subject application.
J. PROPERTY OWNER. Any individual or entity owning property within the boundaries of the city that is connected to a public sewer.
K. PUBLIC SEWER. The sanitary sewers owned or maintained by the city lying within the limits of the public streets, roads, easements, reserves, non-exclusive easements or other public rights-of-way serving or intended to serve two (2) or more separate properties, persons, or parcels. That portion of the building sewer lateral which may lie within any public street or right-of-way is not a public sewer in the city.
L. SEWAGE. Any liquid or solid waste.
M. SMOKE TESTING. A method through which smoke is forced through the sewer lateral waste and/or drain pipes under a slight pressure to find leaks and/or discover evidence of a defective sewer lateral. (Ord. 2012-02 § 1 (part), 2012)
A. New buildings. All new building sewer laterals, including sewer lateral replacements, shall be equipped with a clean-out riser and be fitted with a backflow prevention device of type and materials as approved by the city.
B. Existing buildings. All existing buildings shall be equipped with a clean-out riser. Any existing building in which the elevation of the lowest floor is less than twelve (12) inches above the rim elevation of the nearest upstream manhole or junction structure in the reach of a city main sewer into which a building sewer lateral connects, shall also be protected from backflow of sewage by installing a backflow prevention device of a type and in the manner prescribed by the city.
C. All buildings. Any such backflow prevention device shall be installed by the property owner of the property on which the building is constructed, and shall be located on the lateral between the building and the property line, preferably at the location of the clean-out. The backflow prevention device, if below grade, shall be enclosed in a suitable concrete utility box with removable cover and shall be readily accessible for Inspection and maintenance. The installation of any such backflow prevention device shall be at the sole cost and expense of the property owner. The maintenance of the backflow prevention device shall be the sole obligation of the property owner or the property owner's successor in interest. The city shall be under no obligation to ascertain that the backflow prevention device continues in operating condition. (Ord. 2012-02 § 1 (part), 2012)
It shall be unlawful for any property owner to maintain a building sewer lateral in a defective condition. As used in this chapter, DEFECTIVE CONDITION includes, but is not limited to:
1. Displaced joints, leaks or breaks;
2. Root intrusion;
3. Substantial deterioration;
4. Damaged, uncapped or missing sewer clean-out;
5. Damaged or missing backflow prevention device;
6. In a condition that will allow infiltration and inflow of extraneous water, including, but not limited to rain, storm water or groundwater, or which allows exfiltration of sewage;
7. In a condition that materially increases the possibility of a blockage or overflow;
8. Constructed without a proper permit or with materials not approved by the city;
9. Lack of a manufactured connection to the city's sewer system;
10. Otherwise in violation of city requirements; or
11. In such a condition that the tests required by this chapter cannot be accomplished to the satisfaction of the city.
All sewer laterals or sewer clean-outs which contain sump pumps, down spouts or yard drains that discharge into the public sewer, and all other sources of accidental, negligent or intended introduction of storm run off or similar waters into the public sewer are hereby declared unlawful and are a public nuisance, and shall be abated by the property owner, who is hereby required to remove or correct such improper sewer connections.
