10.10.110 Main extensions.
(1) A main extension and/or special facilities shall be required to service all property which cannot obtain service as outlined in MMC 10.10.100(5).
(2) The following rules shall apply to all extensions:
(a) The minimum size of the sewer main to be installed shall be eight inches in diameter where a larger size is not needed to provide an adequate system, conform with the size of existing mains, meet future needs, or conform to the size specified by the utility’s sewer system facility plan.
(b) All sewer mains shall be public, installed in public rights-of-way or public utility easements. The normal routing for the sewer main extension shall be in a dedicated street right-of-way.
(c) In areas of service below the main system service elevation, special facilities (e.g., pump station) will normally be required in addition to main extensions to provide service.
(d) Financing of Extensions. There are two basic means of financing main extensions, as outlined below.
(i) Total Project Cost. Under this method, the developer is required to pay the total cost of the project. An estimate covering approximate total costs related to the project may be supplied by the utility. If developers install the project themselves or through their own contractor and supply materials, a cash advance sufficient to cover the estimated cost for the utility services needed on the project may be required prior to starting the project. Upon completion of the project, actual costs will be computed and an adjustment made to the contractor or to the utility, as appropriate. In the case of complex projects (projects involving disruption of or cutting into existing roadways, utilities, or pedestrian ways, or other projects where partial completion of the project could result in expense to the utility), the developer may be required to supply a bond to cover the estimated cost of engineering and construction.
(ii) Local Improvement Districts. Local improvement districts may be formed and bonds sold to fund main extensions and special facility projects.
(e) Installers of any and all sewer lines or appurtenances must meet minimum standards. These standards shall include, but are not limited to, insurance requirements, bonding requirements, and experience in the field of sewer line installation. The sewer lines must be installed in accordance with the utility’s specifications which are available upon request. Unless the work is being performed under a City contract, all main extensions shall require a “permit to construct public facilities” and the payment of the associated permit fee. The permit fee shall be set by Council resolution.
(f) If developers install and purchase the material themselves, they must guarantee the project for a period of one year from the date of acceptance of the project by the utility. (Ord. 156, passed 8-13-2019)
