Well 3E Continuing Through 2026

/in /by

Project Description:  This project includes the drilling of a new 20-inch diameter well (completed in 2025), construction of a new well building and installation of a new pump and motor capable of providing 6,500 gallons per minute to the system.  This project is located on an existing well site owned by the District near Hastings and Mayfair Road.

Project Need:  The District requires additional source of water supply to support peak summer (irrigation season) demands in the service area north of the Little Spokane River.  Long-term sustainability concerns are present in the Little Spokane River Aquifer north of the Little Spokane River.  Thus, the District has been working to minimize pumping of that Aquifer by developing additional well sources within the more prolific Spokane Valley Rathdrum Prairie Aquifer.

Expected Outcomes:  Preservation of the Little Spokane River Aquifer resource while maintaining the existing reliable and high level of water service to the District’s customers located north of the Little Spokane River.

Current Status:  Construction of the new well building and installation of new pump and motor was awarded to D.W. Excavating.

Anticipated Schedule:  Construction is underway and is expected to be completed by the end of 2026 with completion by the end of the year.

Project Overview Map:

Funding: The District received a DOE Streamflow Restoration Grant of $1,519,000 for the Little Spokane River Water Resiliency Project, which included design and construction for Well 3E. This funding covers approximately 55% of the total Well 3E project cost, with the remainder of the funding coming from District reserves.

Minihdoka Waterline Improvements

/in /by

Whitworth Water District No. 2 is replacing aging water mains and services on W Koda Ct, Koda Trail, and N Minihdoka Trail. This work will improve system reliability and long-term service to local properties.

What to Expect:

Schedule

Construction began July 6, 2026, and will continue through late September.  Contractor hours will be between 7:00 am and 7:00 pm, Monday through Friday.

Roadway/Access Impacts

  • Temporary road closures or detours may occur. Work begins on N Minihdoka Trail from Dartford to Koda, which is planned from July 6th through late July.
  • Driveways may be blocked for short periods.

For planned blockages, we will notify residents in advance (via door hanger), so that you may plan ahead to park outside the active construction zone.

Surface Impacts

The majority of the project impacts the existing road surface.  However, portions of work may disturb private surface improvements located within the public rights of way or easements.  We are making every effort to minimize disruption and restore these improvements as closely as possible to their original condition.  Additional details are provided below.

Surface Impacts and Restoration: 

Hardscape (includes driveways, retaining walls, and fencing)

We will repair or replace impacted hard surfaces (concrete, asphalt, gravel) and reinstall affected walls and fences. You may choose to remove items in advance if preferred.

Lawn, Vegetation, and Tree Removals & Restoration

Disturbed lawns will be restored with sod or seed. Property owners will be responsible for watering and maintenance after installation.

We will preserve landscaping where possible. If removal is necessary, the ground will be restored, but plant replacement will be the property owner’s responsibility.

Sprinkler Systems

Damaged sprinkler lines or heads will be repaired. If issues are noticed after construction, please contact us and we will address them promptly.
