Connection to properties outside of the city’s municipal boundaries is discretionary. No water connection to any lot or parcel containing an improved structure may be made to persons or property outside the city limits or current service boundaries without first having executed either a developers extension agreement, annexation agreement or no-protest annexation agreement as determined by the city council. Fees and charges shall be no less than fees and charges or other conditions for applicable hookup and service within the city as currently exist or as may hereinafter exist in the future. The city may provide for different terms and conditions for the owners of any properties upon which it locates or seeks to locate any municipal utility facilities for purposes of Section 13.20.030 and this section for purposes of acceptance of water supplies into the city’s supply system through utility/landowner agreements, development agreements, interlocal agreements with Kittitas County and other jurisdictions, no-protest annexation agreements, or developer extension agreements. To the extent permitted by law, the city may impose surcharges and rates different from those charged to classes of customers located within the city’s boundaries; provided that, these rates, conditions, and charges are reasonably related to the cost and system impact of extending service requested by the owner of real property or lawful occupant, maintaining system capacity and operational reliability, maintenance, improvements, repairs, storage, pressure zone requirements and fire flow capability, and other factors determined to be reasonable and necessary by the city council. Any customer granted water under these terms and conditions shall also be subject to mandatory city water conservation programs, including but not limited to conservation surcharges, conservation devices and equipment, time of use restrictions, and increased rates for usage above adopted rates by the city.
