Little Spokane River Water Supply Resiliency Project

Whitworth Water District (District) is the largest water purveyor within unincorporated Spokane County. The District provides water service to approximately 11,000 connections accounting for approximately 35,000 residents. The District’s current retail service area is highlighted in tan on the above map.

District’s Little Spokane River Water Supply Resiliency Project:

The District’s Little Spokane River Water Supply Resiliency Project (Project) encompasses two new high production wells (one of which is already constructed), and four and a half miles of 24” pipeline. The Project is anticipated to $14 million dollars.

The Project will effectively bridge the infrastructure and water supply gap between two groundwater sources: the Spokane Valley Rathdrum Prairie aquifer (SVRP); and the Little Spokane River aquifer (LSR). The SVRP is considered by many to be one of the most prolific aquifers in the world, while withdrawals from the LSR more directly, and negatively, impact stream flows of the Little Spokane river leading to increased water rights issues and the potential for adverse ecological impacts.

Demands in the Little Spokane River Aquifer:

During the District’s Water System Planning process in 2018, it was determined that additional District source capacity was required to support future growth within the LSR. The most cost effective and timely approach would have been for the District to construct additional wells in the Little Spokane river aquifer. Given the Hirst decision and resulting RCW 90.94, the District decided to play a leadership role and avoid further increasing Little Spokane river aquifer deficits in an already taxed and fragile watershed system.

Instead of increasing impacts to the LSR, the District developed a plan to drill a series of wells and transport that supply through new transmission lines from the SVRP up to the service area of the LSR. To date, the District has invested over $7.3 million toward these improvements (see map above), which have included:

  1. Acquisition of property for three new groundwater wells to be developed in Spokane Valley Rathdrum Prairie aquifer for use in WRIA 55.
  2. 9,500 feet of 24-inch transmission main (Phase I) connecting District WRIA 57 wells to its WRIA55 service area.
  3. Development and activation of District Well 3D (4,300 gallons per minute).

Benefits to Spokane County and the LSR:

This project is in direct alignment with Spokane County’s Comprehensive Plan – Capital Facilities and Utilities Goals and Policies.

A large portion of the Little Spokane River aquifer area within Spokane County is located within the boundary of the District’s retail or future service areas. RCW 90.94 does not require water offsets nor monitoring by Spokane County so long as new development is connected to a municipal water purveyor. As a means to provide necessary long-term water supply to the LSR, it is critical that the District’s Little Spokane River Water Supply Resiliency Project is completed.

System Resiliency:

While this project focuses on the ability to transfer water from the more abundant SVRP to the LSR, there is a residual benefit of this project to system resiliency. That is, the construction of the large diameter transmission main between the two aquifers also allows the District the ability to move water from LSR to SVRP in the event of a contamination event that impacts the District’s sources within the SVRP.

Additional Work Required:

Phase II of the Little Spokane River Water Supply Resiliency Project requires an additional 3.4 miles of 24” transmission main from the vicinity of Dartford Road and Mill Road to Midway Road (where Phase I left off).

The last components of the Project, a high production well (Well 3E) will provide the District an additional 4300 gallons per minute of source capacity from the SVRP to the LSR to support future demands.

Remaining Project Funding Required:

The District estimates that the 24” Main Phase II will cost $7.5 million to construct. In 2021, the District was awarded two low interest loans to complete the 24” Main Phase II. These loans included $5.0 million from the Washington State Department of Health’s Drinking Water State Revolving Loan Fund (DWSRF) and $1.56 million loan from the Public Works Board. The District is also actively seeking $4 million in American Recovery Plan Act grant funding through Spokane County to accomplish Phase II.

Phase II – Transmission and Distribution Work

 

Project Description

Phase II of the transmission and distribution work for the District’s Little Spokane River Water Supply Resiliency Project (Project) consists of the installation of over 3.4 miles of 24” Ductile Iron Waterline which includes crossing Dartford Bridge and installing a 300’ bore underneath US 395. The new Transmission Main will be installed within existing rights of way along N Dartford Drive, E Commellini Road, N Wandermere Road, N Hatch Road, and E Midway Road. 

In January of 2022, the project was publicly bid and later awarded to Halme Construction, Inc. based out of Spokane, WA. Halme plans to begin mobilization and the installation of site controls in May of 2022. Installation of the waterline will begin on E Midway Road (near Little Spokane Drive) and continue west and then south over to N Dartford Drive, ending just south of the Little Spokane River.  

Purpose

Whitworth Water District wishes to notify our customers of the upcoming Phase II of the Project.  This project will be constructed between Spring 2022 and Summer 2023. We will keep you informed of the project status and any changes to the schedule so the community is able to effectively plan ahead. 

Traffic Impacts

Residents traveling N Dartford Drive, E Commellini Road, N Wandermere Road, N Hatch Road, and E Midway Road should anticipate traffic slowdowns and/or possible closures during the waterline installation this Summer and into the Spring of 2023.  

Funding

The District secured over $6.5 million in low interest loans through the Washington State Drinking Water State Revolving Loan Fund and the Washington Public Works Board to complete Phase II. The District has also applied for $4 million in American Recovery Act grant funding through Spokane County to accomplish Phase II.  

Project Background and Need

The District serves customers on its southside with water from the Spokane Valley Rathdrum Prairie aquifer (SVRP). District customers on the northside of the district are served from water from the Little Spokane River aquifer (LSR). 

The District’s 2018 Water System Master Plan identified the need for more wells to be constructed within the LSR. However, watershed and water supply limitations in the LSR preclude development of additional sources. The SVRP is not subject to these same limitations.   

Thus, the District is in the process of implementing a series of capital improvements which include development of source capacity in the SVRP and the transfer of this water to Zone 8 into the LSR portions of the District’s service area through dedicated transmission mains.  These improvements provide a significant benefit to the District through increased capacity and improved system reliability.  These improvements are briefly described and highlighted on the maps above and to the right.  

  1. Well 3D:  Drilling and development of a 4300 gpm well source, completed in 2020. 
  2. Well 3E:  Drilling and development of a second 4300 gpm well source, to be completed in 2024.
  3. Phase I Transmission Project (Mill Road):  Installation of 9,500 feet of 24 inch water main, completed in 2019.
  4. Phase II Transmission Project (Zone 3 to 8 Transmission Main):  See information herein.

Spokane County sets aside $4 million for water infrastructure

“It’s a way to bring water to an area that doesn’t have enough water,” County Commissioner Josh Kerns said. “That’s the simple way to explain the project.”

The $4 million will come out of the $101 million the county received from the federal government’s American Rescue Plan, a $1.9 trillion stimulus bill aimed at helping the economy recover from the COVID-19 pandemic.

Many infrastructure projects, including road improvements, are ineligible for American Rescue Plan funding, but water-related infrastructure projects are allowed. The county previously set aside $5.5 million to address chronic flooding problems on the West Plains.

Whitworth Water District General Manager Tim Murrell said one must understand regional hydrology and Washington law to understand why the $14 million project is necessary.

The Whitworth Water District, which serves 30,000 customers in unincorporated Spokane County north of Spokane, sits atop two aquifers.

The Spokane Valley-Rathdrum Prairie Aquifer lies underneath the southern end of the district.

“That’s one of the most abundant, robust aquifers in the world,” Murrell said.

The Little Spokane River Aquifer isn’t.

That less abundant aquifer lies beneath most of the Whitworth Water District’s service area, and it’s been depleted over time.

How the county manages the Little Spokane River Aquifer changed six years ago.

In 2016, the Washington Supreme Court issued what’s commonly referred to as the Hirst decision. The ruling said counties must ensure enough water is available for existing well users before they allow new wells.

“That limited development – basically stopped development – in the Little Spokane aquifer because of the impacts those new exempt domestic wells would have had on the stream system,” Murrell explained.

Following the Hirst decision, the Whitworth Water District looked at how it could meet the needs of existing well users while allowing for new development and maintaining adequate streamflows in the Little Spokane River.

The district came up with a few ideas, including the $14 million Little Spokane River water supply resiliency project.

The concept’s fairly simple.

The Whitworth Water District will take water out of the Spokane Valley-Rathdrum Prairie Aquifer using a well near the intersection of Hastings Road and Division Street.

The district will then pump that water north through 5.4 miles of 24-inch pipe to a site near Midway Elementary School.

“It will minimize the amount of water that we have to pump out of our existing Little Spokane wells,” Murrell said. “It’s basically a replacement project. For every gallon we pump out of the SVRP, we have to pump less out of the Little Spokane.”

The project could be completed by next spring.

Not only will the project help the county allow more development in the wake of the Hirst decision, it’ll also have ecological benefits.

Murrell said that by reducing withdrawals from the Little Spokane aquifer, the Little Spokane River should have improved streamflows, especially during the dry summer months.

Murrell said the new infrastructure will also have direct financial benefits for property owners.

The new system will be more efficient, which will mean cheaper water for customers. Murrell added that the county’s $4 million investment will reduce costs to property owners too, because the water district would otherwise be funding the project on its own.

“We’re not doing this just to benefit the Little Spokane,” Murrell said. “It also benefits our ratepayers.”

A Note from the Chairperson

As we enter another summer season, Whitworth Water continues its work of providing an always reliable source of high-quality water for our customers.

One of the District’s major tasks is the Little Spokane River Water Supply Resiliency Project, involving two new high-production wells and four and a half miles of pipeline. This project – already complete – will allow the District to increase its reliance on the robust  Spokane Valley Rathdrum Prairie aquifer (SVRP), and take pressure away from the Little Spokane River aquifer (LSR).  The project will increase our ability to serve the northern areas of the district.

Fiber-optic cable is coming!  Some of you may have noticed a flurry of new colors painted on the streets, sidewalks, and lawns in your neighborhood, as TDS puts in new fiber optic high-speed internet.  This involves a great deal of work for our folks, who must locate all water lines before any digging can be done.

For me, it has been a real pleasure to work closely with both the Whitworth Water administration and operations department as part of the Whitworth Water Commission.  We are all lucky to have such a fantastic group of folks and I look forward to continuing to work with them and the other Commissioners in the future.

Thank you,
Jean Pond

Manager’s Report

What a great time for Whitworth Water District! This year certainly threw us some curveballs including a pandemic, increased costs for materials, and supply and demand issues. But the past year can also be looked back upon as a year with plenty of successes. We have completed numerous District projects, managed to maintain water service during inclement weather events, all while keeping water rates among the lowest in Eastern Washington. This coming year looks to be just as busy.

Interested in keeping track of what we are up to? Curious about our water quality, shutoff notifications, District projects, and other news? Have a question, observation, or comment? Follow us on Facebook, Instagram, and or Twitter or reach us via email at billing@whitworthwater.com. We look forward to hearing from you!

Thank you,
