The common council of the city, within its judgment, may provide that persons within the city not now served by the public sewer system and desiring to be served by a public sewer be allowed to construct the sewer on such properties all in accordance with plans and specifications as approved by the city engineer and the DEQ. (Ord. 10-04, 2010; Ord. 801 Art. 5 § 1, 1983)

13.48.020 Extensions – Specifications and costs.

All extensions of city sewer lines shall adhere to the applicable provisions of the Silverton improvement ordinance. (See Chapter 12.08 SMC.) In addition, such sewer extensions shall conform to the following:

A. Extensions of all lines will be to the far end of the property requesting service. If, however, the terrain or other physical features prevent future extensions of the sewer line beyond the property, then the sewer extension may terminate at a point perpendicular to the last possible developable site.

B. A minimum of eight-inch sewer line size shall be used on all extensions; however, the last nonextendable 250 feet of sewer line may be six inches in diameter. In all cases, the line size shall be determined by the city engineer.

C. Sewer service will be required from the fronting street unless both natural terrain prohibits and the city engineer determines a minimum of three properties will be better served from a main to be constructed through a permanent public utility easement. All such easements shall be of adequate dimensions to allow for all repair and replacement with conventional equipment.

D. The city will share in the cost of a sewer line larger than eight inches in diameter by paying the difference in cost between an eight-inch line and the larger size, subject to the following conditions:

1. Participation shall be governed by limits placed on the city budget.

2. The city will not in any case share in costs for lines larger than eight inches if the new development requesting service requires the larger line for its own use.

3. When the line size is greater than eight inches in diameter, but not greater than 10 inches, only the difference between eight-inch and the larger pipe and fitting material costs may be paid by the city. When the line size is greater than 10 inches in diameter, pipe and fitting material costs above that for an eight-inch line may be paid by the city. In addition, when the line size is greater than 10 inches in diameter, normal installation costs (i.e., excavation, bedding, backfill and surfacing above that for 10-inch line) may be paid by the city. In all cases where a developer is requesting city cost-sharing, records and receipts shall be provided to the satisfaction of the city engineer. The city engineer will determine if the request is justified and authorize or deny reimbursement accordingly.

E. The cost for extending new sewer lines shall be the responsibility of the owner requesting service. If a newly developed property requires service from a portion of the sewer line paid for by the original developer, then the city shall collect a proportionate share of the sewer line cost and reimburse the original property owner or assignee that amount, less administration costs. This reimbursement policy shall continue for 10 years from the date of line construction and then end.

F. When service is requested by a new development fronting a sewer line less than eight inches in diameter, the city engineer will determine whether average peak hydraulic capacity will be exceeded with the additional inflow. If the capacity will be exceeded, then the developer will be required to pay for the replacement of all undersized lines, including manholes and cleanouts, necessary to correct hydraulic deficiency.

1. Upon replacement of any undersized line, at the property owner’s expense, the owner or the owner’s assignee may be eligible for city cost-sharing and reimbursement by other developers in a manner similar to new sewer line extensions.

2. Also, if the property was previously assessed by the city for the undersized line, a credit of the original assessment amount will be given toward construction of a new line. The property owner shall initiate any request for such credit and shall provide written documentation to the satisfaction of the city manager that the assessment is valid.

G. An engineering fee shall be paid by the requesting property owner(s) to the city, based on services provided for design, inspection and/or contract administration. (Ord. 10-04, 2010; Ord. 801 Art. 5 § 2, 1983)

13.48.030 Extensions – Completion conditions.

A. When a sewer extension is to be completed by a private contractor under supervision of the city engineer, the city and the person(s) doing the work shall agree as to the time within which the sewer extension work shall be completed.

B. Upon completion and acceptance of the work by the city engineer, all sewer mains, laterals and service connections shall become the property of the city free and clear of any and all expenses for the construction and installation thereof. The person completing the work shall, prior to turning over the work to the city, provide a plat showing all of the property served by the completed construction and lots, parts of lots or parcels of ground actually connected to the sewer extension, and where connected.

C. Each of the owners of such lots, parts of lots or parcels of land shall, when connecting to the sewer, pay to the city a system improvement fee and service connection charge for the type of property served.

D. The person completing the work shall provide a one-year bond or other suitable security which will indemnify the city against loss should the sewer extension prove faulty. In addition, prior to acceptance of the work by the city, the person completing the work shall be required to televise the sewer extension one year from the date of completion of the work. (Ord. 10-04, 2010; Ord. 801 Art. 5 § 3, 1983)

13.48.040 Disconnection and reconnection procedures.

A. When any structure connected to the sewer system is destroyed by an act of God, is removed or is torn down, and/or no longer usable, it shall be required to disconnect from the sewer. The owner shall advise the city, stating the date of destruction or removal of the structure, and pay all user service charges to the date of destruction or removal, and thereafter no user service charge shall be made to the property until new improvements, if any, are placed on the property.

B. When the property is relieved from user charges and then reconnected to the sewer, the city shall check its records and determine whether or not the property had paid into the sewer fund the amount required while the property was using the sewer. If the property had paid user service charges equal to the amount required under sewer rates that were in effect at the time of disconnecting from the sewer, no additional charges will be levied.

C. In addition, when a building with sewer service is destroyed, or relocated to a different property and thereafter replaced by a new building within five years from the date of destruction or removal, the city shall not levy a system improvement fee for the new building unless the new building constitutes an increase in use under the system improvement fee schedule currently in effect. If the replacement building requires a greater system improvement fee when compared to the destroyed or relocated building previously on the same site, then a credit will be given on the replacement building system improvement fee equal to that of the previous building fee, and when the above provisions of this section are met.

D. The current system improvement fee schedule will be used for all comparisons and credit determinations under this section.

E. When a destroyed or relocated building is not replaced by a new building within five years of the date of destruction, then any replacement building shall pay the difference in system improvement fees in effect at the time of application for sewer service and the date of destruction or relocation of the building. (Ord. 10-04, 2010; Ord. 801 Art. 5 § 4, 1983)
