Case Study: Well Design, Construction, & Testing: Ford Hatchery

Client: Washington Department of Fish & Wildlife (WDFW) Location: Stevens County (Spokane), WA Contact for water resource projects: Tim Flynn

Project Background & Challenges

WDFW required a well that could produce 400 gpm at the Ford Hatchery to improve water quality during egg incubation and to increase species survivability. Ecology authorized a transfer of 400 gpm (maximum instantaneous quantity) from an existing surface water right.

Solution

Aspect prepared bid specifications, administered the bid, subcontracted drilling services to Fogle Pump and Drill, and oversaw drilling and logging operations. We also designed the well, specifying 60 feet of screen to maximize yield and efficiency and to reduce pumping lifts. The new well was tested at rates exceeding 500 gpm and is capable of significantly greater yields. Step-drawdown test results showed the well to be performing efficiently.
