Chapter 13.10 SEWER REGULATIONS

This chapter sets forth uniform requirements for dischargers into the city sewage works and enables the city to protect public health in conformity with all applicable local, state and federal laws relating thereto.

The objectives of this chapter are the following:

A. To promote the health, safety and welfare of those persons within the city’s public sewer system by requiring use of the sewage works;

B. To prevent the introduction into the sewage works of pollutants that will interfere with the normal operation of the sewage works that would not receive adequate treatment and which would pass through the sewage works into receiving waters and/or the atmosphere or otherwise be incompatible with the sewage works;

C. To ensure that the quality of sludge from the sewage works is maintained at a level which allows its use and disposal in compliance with applicable statutes and regulations;

D. To protect sewage works personnel who may be affected by sewage in the course of their employment and to protect the general public;

E. To enable the city to comply with all its permits, conditions, sludge use and disposal requirements and any other federal or state laws to which the sewage works is subject. [Ord. 852 § 2, 1997.]

The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the superintendent. A permit and inspection fee for a residential or commercial building sewer permit, and for an industrial building sewer permit, shall be paid to the city treasurer at the time the application is filed. In the event that one permit is issued for a single connection serving more than one residence or commercial user, then the total sewer connection permit fee shall equal the number of such users on the connection times the permit and inspection fee for a single user.

C. Application for the permit required by the foregoing section shall be filed with the city, stating the name of the owner, the correct address and proper legal description of the property to be served, dimensions and locations of any buildings on the property, the whole course of the building sewer from the public sewer to its connection with the building or property to be served, and other such plans and information as may be required.

D. Upon approval of the application and issuance of the permit, it is unlawful to alter the permit or to perform any work other than is provided for in the permit.

E. Any application for sewer service shall include elevation drawings of the building lot taken from a survey of the lot.

F. When an application for connection is approved, the applicant has 15 days to pay all appropriate fees to the city. If said fees are not paid within 15 days, the approval for said connection is withdrawn and terminated without further notice.

G. The permit required by this chapter must, at all times during the performance of the work and until the completion thereof and approval by the city, be posted in some conspicuous place at or near the work and must be readily and safely accessible to the superintendent or his representative.

H. No building sewer contractor shall break, alter or tamper with any public sewer, except that he may tie into a connection which exists for that purpose under the supervision of the superintendent. [Ord. 966 § 2, 2004; Ord. 852 § 2, 1997.]

13.10.150 Separate sewer for each building.

A separate and independent building sewer shall be provided for every building; except, that where one building stands at the rear of another on an interior lot and no public sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer. Further requirements for a separate sewer are as follows:

A. In making all connections with the public sewer system, each property capable of the title transfer and each residence or business located on any one property and not joined with other property thereon inseparable shall be considered as an individual consumer and each individual consumer shall be supplied through a separate service connection; provided, however, that in case of duplexes or businesses or apartments not being capable of separate title transfer, the owner thereof may nevertheless by arrangement with the city provide for the property multiple service connections to serve each of the various units located thereon. All buildings, although joined together by party wall or similar attachment if capable of separate title transfer, shall have, for each divisible part thereof, separate service connections.

B. No new service connection shall be made to any building or other structure unless it is used predominately for a residence, employment or other public use unless the owner of the land on which the building or structure sits has a building used for a residence, employment or other public use on the same land and the building is in conformity with state, county and city regulations governing its uses.

C. If a building sewer is to serve more than one property by joint agreement of the owners, the city shall approve any document containing such agreement, ensuring that all properties involved shall have perpetual use of the building sewer, and having provisions for maintenance and for access for repair purposes, and such agreement shall be signed by the recorded owners.

D. This agreement document shall be notarized and recorded with the superintendent and shall be referred to as an “easement.”

E. The provisions of Chapter 13.20 RMC relating to delayed benefit agreements shall apply. [Ord. 852 § 2, 1997.]

13.10.180 Use of backwater valve required.

A. A backwater valve shall be installed in all building sewers constructed after the effective date of the ordinance codified in this chapter. The backwater valve shall be of the type and design as to effectively prevent the back-flow of sewage from the public sewer through the building sewer, caused by plugging of the public sewer or through normal operation of the public sewer, including cleaning activities. The backwater valve shall be installed at a location in the building sewer such that access to the valve will be on private property and no construction within the public right-of-way will be required to access, install, operate or maintain the backwater valve.

B. All costs associated with the purchase, installation, operation, and maintenance of the backwater valve shall be borne by the owner or person responsible for the building sewer. Effective operation of the backwater valve shall be the responsibility of the owner.

B. No building sewer trench shall be filled or any sewer covered until the work shall have been inspected and approved by the superintendent.

C. If the superintendent finds the work or materials used are not in accordance with previous approval or permit, the superintendent shall notify the person doing the work and/or owner or occupant of the premises by letter and posting of notice on the property.

D. If any work done under a permit granted as provided herein is not done in accordance with the provisions of this chapter and the plans and specifications approved by the city, or when any building sewer is constructed, laid, connected or repaired and does not comply with the provisions of this chapter, or where it is determined by the city that a building sewer is obstructed, broken, or inadequate and is a menace to health, or is liable to cause damage to the sewer system, or subsection C of this section is violated, then, after notice by the superintendent, the contractor, owner or person doing the work, as the case may be, refuses to properly construct, repair or complete such work within the time specified in such notice, the city shall disallow connection to the public sewer system until such time that all such work allowed under the permit has been done in accordance with the provisions of this chapter. [Ord. 852 § 2, 1997.]
