SEPA-012-2022 (Well No. 3 Replacement)
City of West Richland, Public Works Department
Location of Proposal:
Well #3 is located adjacent to the east intersection of N 62nd Ave and Deer St (Parcel no. 136071000001001). The new Well #3 and pump house will be constructed in the vacant lot west of N 62nd Ave, south of Tapteal Elementary School, north of Desert View Mobile Home Park, and east of the existing center-pivot irrigation circle. The vacant lot is also part of parcel no. 136071000001001.
Description of Proposal:
The project includes design, permitting, and constructing a new groundwater well, associated well building, telemetry equipment, on-site back-up power generator, disinfection system, water main, security fencing, and miscellaneous site improvements. The new well and pump house will be constructed on the vacant lot west of N 62nd Ave. During drilling and testing of the new well, the City will discharge native groundwater produced during drilling and aquifer pumping testing onto vacant DNR property adjacent to the new well. In addition, a temporary cuttings and drilling water collection pit will be situated adjacent to the west of the new well. Following development, the new well will be connected to the existing City water delivery infrastructure. The overall size of the project site is 445,420 sf, off which approximately 40,000 sf will be fenced off following completion of construction. Fenced off area in the northeastern corner of the site will contain well house and all water system infrastructure needed to connect the well to the City potable water supply system.
Following completion of the new well, the existing Well #3 and the associated pump house will be decommissioned and removed. The new Well #3 is intended to be in operation by the first quarter of 2024.
