Section 2 - Extensions and Service Policies

2.4 Fees And Charges

All fees and charges related to development shall be in accordance with the latest Carson and Underwood Water Rates.

2.3 Water Meters
  1. Water meters sized ¾ inch (⅝ inches by ¾ inches) or 1 inch shall be furnished and set by the PUD only after the System Development Fee is paid by the landowner. Water meters will be set after the meter box and service piping are placed at proper finished grade.
  2. Meters one and one-half inch (1 to ½ inches) and larger will be installed by the developer as part of the construction project only after the System Development Fee is paid by the landowner.
  3. All irrigation systems require the installation of state certified backflow devices. Irrigation meters will be set and turned on after acceptance of the water system by the PUD.
  4. Adjustments, repairs, or replacement of the service line after the meter shall be the responsibility of the property owner.
  5. Any water service modifications requested by a property owner shall be billed by the PUD on a time and material basis.
2.2 General Design Considerations
  1. In all residential and commercial developments, water main extensions are required to assure orderly development of the water utility system by complying with the PUD’s requirements for development, water quality, pressure zones, and fire protection.
  2. Design and construction of water mains, including but not limited to mainlines, valving, fire hydrants, fire sprinkler connections with backflow devices, domestic and irrigation services, pump stations, pressure reducing stations, telemetry and other appurtenances shall be in compliance with PUD ordinances, special requirements of the PUD, these standards, and the most recent version of the Standard Specifications for Road, Bridge, and Municipal Construction (Standard Specifications) as produced by the Washington State Department of Transportation.
  3. The applicant is responsible for designing the proposed water system(s). The system(s) must be designed by an engineer licensed in the State of Washington and approved by PUD.
  4. Main line pressure reducing devices are to be designed, constructed, and paid for by the applicant and approved by PUD.
  5. Pressure reducing valves on individual services may be required at the discretion of the PUD. Such valves will be installed after the meter and will be the responsibility of the homeowner to install and maintain.
  6. Customer owned booster pumps may be allowed on a case-by-case basis provided they satisfy the design and construction standards. The maximum capacity of the booster pump shall be sized at 50 percent of the rated capacity of the water meter. The customer shall provide sufficient information on the pump to the PUD indicating the capacity and that it satisfies this criterion. A backflow device is required between the meter and the booster pump.
  7. The developer shall be responsible for ensuring that water system pressures associated with the proposed water system extension meet the criteria described in Section 3.1, and shall provide documentation showing as such. At the sole discretion of the PUD, the developer may be required to perform hydraulic modeling of the existing / proposed water system to ensure minimum system pressures are maintained under high water demand scenarios. If hydraulic modeling is required, the PUD will provide a digital files in WaterCAD format to the developer. The developer shall then submit an updated model to the PUD in WaterCAD format showing that minimum water system pressures will be maintained under high water demand scenarios. The revised hydraulic model will be reviewed by a third-party engineering firm selected by the PUD. Alternatively, the developer may pay for such modeling to be performed directly by a third-party engineering firm selected by the PUD. In either instance, all costs associated with the hydraulic modeling / review shall be borne by the developer.
2.1 Developer Extension Process
  1. When extension of the existing water system is required for service, the developer shall submit a service request to the PUD. The PUD will then contact the developer to discuss project details and requirements in a timely manner.
  2. Upon completion of the design and tentative approval by the PUD, a pre-construction letter of requirements will be sent to the owner noting requirements to be completed prior to construction. Upon completion of the pre-construction requirements and 48-hours’ notice, a pre-construction meeting will be held with the PUD at which time construction inspection will be scheduled. No water main construction work shall commence prior to the pre-construction meeting. After completion of construction and submittal of required documents and fees, final acceptance will be given by the PUD at which time service will be available by application following payment of fees for water meters.
  3. The owner is required to provide a surety bond for the project for a period of 1 year after acceptance.
  4. Developer extension projects shall be deeded to PUD for maintenance and operation by letter after the 1 year warranty period has expired.
