(a) No person other than the person specifically excepted by this chapter shall commence, do or cause to be done, construct or cause to be constructed, use or cause to be used, alter or cause to be altered any public sewer, mainline sewer, house lateral, sewage pumping plant, water pollution control plant, or other similar appurtenance in the city without first obtaining a sewer construction permit from the city engineer.

(b) A sewer construction permit issued by the city engineer shall expire one year from the date of issuance, except when the plans were approved in accordance with an agreement either with another governmental agency, or with the city in accordance with the city's subdivision ordinance, or reimbursement in accordance with subsection 13.00.320(d), the permit shall be valid for the period specified in the agreement.

(Ord. No. 14(1989), § 2(20.32.010), 6-27-89)

The provisions of this chapter requiring permits shall not apply to contractors constructing public sewers and appurtenances under contracts awarded by the city council and entered into under proceedings had or taken pursuant to any of the special procedure statutes of this state providing for the construction of sewers and the assessing of the expense thereof against the lands benefited thereby, or under contracts between the contractor and city council.

(Ord. No. 14(1989), § 2(20.32.020), 6-27-89)

(a) Any person requiring a sewer construction permit shall make written application to the city engineer.

(b) The city engineer shall provide printed application forms for the permits provided for by this chapter, indicating thereon the information to be furnished by the applicant. The city engineer may require, in addition to the information furnished by the printed form, any additional information from the applicant which will enable the city engineer to determine that the proposed work or use complies with the provisions of this chapter.

(Ord. No. 14(1989), § 2(20.32.030), 6-27-89)

No sewer construction permit shall be issued until the city engineer has checked and approved the plans in accordance with section 13.00.1200 and the other applicable provisions of this chapter.

(a) When, in the opinion of the city engineer, it is necessary to connect a house lateral to a public sewer at a point where no connection facility has been provided, application for a public sewer tap shall be submitted and a fee for tapping the public sewer shall be paid by the applicant before the permit is issued for the construction of the house lateral. All tapping of public sewers, except trunk sewers, shall be performed by the city engineer.

(b) Exception. Tapping of the public sewer as required on sewer plans approved by the city engineer shall be constructed by a licensed contractor.

(Ord. No. 14(1989), § 2(20.32.050), 6-27-89)

Before granting any permit for the construction, installation, repair or removal of any sewer, or appurtenances thereto, which will necessitate any excavation or fill, in, upon or under any public street, highway or right-of-way under the jurisdiction of another public agency, the city engineer shall require the applicant to first obtain a permit from the agency having jurisdiction.

(Ord. No. 14(1989), § 2(20.32.060), 6-27-89)

Before granting a permit for the construction of any sewage pumping plant or water pollution control plant, the city engineer shall check and approve the plans or required modification thereof as to their compliance with county, state and other governmental laws or ordinances, and shall require that the facilities be adequate in every respect for the use intended.

(Ord. No. 14(1989), § 2(20.32.070), 6-27-89)

(a) Any person proposing to have sewage discharged from any property to a public sewer in quantities or at a rate greater than the capacity for which the sewer was designed, when proportioned to such property, and which such additional quantity will immediately overload the sewer, shall be denied a permit to connect any facilities to the sewer which will discharge more than the proportionate share allotted to the property. However, if such additional discharge will not immediately but may in the future overload the sewer, a conditional permit to connect to the sewer may be issued after the owner of the property agrees by a covenant satisfactory to the city engineer recorded against the land to construct or to share in the cost of construction of additional sewer capacity at such future time as the city engineer determines that an overload situation exists or is imminent.

(b) The owner of the property shall supply a faithful performance bond guaranteeing compliance with the terms of the covenant, in a penal sum which, in the opinion of the city engineer, equals the future cost of construction of sewer facilities to carry such additional discharge.

(c) The faithful performance bond shall be kept in full force and effect until such additional discharge is discontinued or until such additional sewer facilities are completed, and this obligation shall pass to succeeding owners of the property.

(d) If any owner fails to supply and keep in effect the required faithful performance bond or fails to comply with the terms of the covenant, the conditional permit allowing such additional discharge may be revoked, and the continuing of such additional discharge thereafter will constitute a violation of this chapter.

(e) The provisions of this section shall also apply to any property previously connected to a public sewer, the discharge from which is later proposed to be increased or is found to have been increased substantially beyond the proportionate share of public sewer capacity allotted to the property.

(f) The provisions of this section do not apply to properties subject to any ordinance which requires payment for additional sewer capacity prior to the issuance of a building or sewer connection permit.

(Ord. No. 14(1989), § 2(20.32.080), 6-27-89)

The city engineer may issue sewer connection permits for two or more buildings to be served by a temporary private sewage disposal system if all of the following conditions have been met:

(1) The sewer collection system has been constructed in accordance with the provisions of this chapter.

(2) A permanent sewage disposal system has been approved as to concept, plans and land use by all state and local regulatory agencies having jurisdiction.

(3) The construction of a permanent sewage disposal system has been guaranteed to the satisfaction of the city engineer and the director of health services, either by the posting of bonds in accordance with the city subdivision ordinance or by other satisfactory assurances.

(4) The temporary sewage disposal system is approved by the city engineer, the director of health services, and all other state and local regulatory agencies having jurisdiction. The conditions for such approvals shall include a stated time limit for the use of such temporary system, and shall provide for the termination of such use and the connection to the guaranteed permanent sewage disposal system.

(5) A cash deposit in an amount established by the city engineer has been deposited with the city engineer to ensure the satisfactory maintenance of the temporary sewage disposal system.

(6) Provision has been made for the inclusion of the area served by the temporary sewage disposal system in a sewer maintenance district or other taxing entity capable of generating adequate maintenance and operational funds in the event that public operation of the temporary system should become necessary.

(b) Further, if such lot may in the future be included in a special assessment improvement district which would provide sewers for such lot and adjoining area, such connection permit shall not be issued until the connection charge specified by section 13.00.830 and any other applicable charges have been paid, and the property owner has executed and recorded in the office of the county recorder a waiver which states that he will not protest inclusion in, and will pay the assessment for, such improvement district. Such waiver and agreement shall be part of the conditions of ownership of the property and shall be binding on all heirs, successors and assigns to the property.

(Ord. No. 14(1989), § 2(20.32.180), 6-27-89)
