Site work for a water / sewer project in Caldwell, Idaho. Completed plans call for site work for a water / sewer project.

City of Caldwell is requesting bids for the construction of Test Well 25. The project consists of drilling and constructing a municipal test well, including all labor, materials, equipment, testing, and associated work necessary to complete the project. The project site is located on Caldwell Housing Authority property at the southeast corner of State Highway 44 and Farm way /Kent Ranch Road in Caldwell,Idaho, legally described as the NWNW Section 9, Township 4 North, Range 3 West. Work includes installation of surface casing and annular seals in accordance with IDWR standards, drilling of a pilot borehole, collection of lithologic samples, and completion of geophysical logging including normal resistivity, single-point resistance, and gamma logs. Graded sand filter packs and cement-bentonite annular seals will be installed between screened intervals to hydraulically isolate targeted aquifer zones. The collected drilling and geophysical data will be used to evaluate aquifer characteristics and groundwater quality, and to finalize completion intervals for the monitoring wells. The project consists of drilling and construction of a multi-level monitoring test well to an anticipated maximum depth of approximately 600 feet. The test well is planned to include up to seven (7) individual monitoring wells within a single minimum 19-inch diameter borehole with 20-inch diameter steel surface casing, with the potential for an additional shallow monitoring well if needed. Monitoring wells are anticipated to consist of 4-inch diameter Schedule 80 PVC casing and slotted PVC screen, designed to accommodate low-capacity test pumping for groundwater quality evaluation. Final screen intervals and well configurations will be determined based on subsurface conditions encountered during drilling, including review of drill cuttings and geophysical logs. Action will betaken by the City within thirty(30) days of the opening date,and the successful bidder will be required to enter into a written contract with the City within ten (10) days after Noticeof Acceptance of the bid.
