A. Project Description

This project is for the installation of a residential drinking water well on fee land. The contractor shall drill the well, consisting of welded steel casing, PVC liner (as needed), sanitary seal, well screen (as needed), well development, test pumping, disinfection, and water sampling. The estimated well depth based on existing nearby wells is 220 feet. The contractor shall drill the well until water is encountered that will provide at minimum 5-gpm of water that meets US EPA drinking water standards, or to the estimated depth indicated on the bid schedule, whichever occurs first. If satisfactory water is not encountered before or at the estimated depth, the contractor shall consult with the Contracting Officer on whether to drill deeper for the approved contract unit cost. All appurtenances, including a submersible pump and pressure system, will be contracted separately. Existing well logs from the surrounding area are provided (see Attachments). These well logs do not guarantee similar geologic formations will be encountered. Further investigation of the site and locating other local well logs is the responsibility of the contractor. Any permits, including the Department of Ecology Notice of Intent, are the responsibility of the contractor. Shall the well not provide sufficient quantity and quality of water, it shall be decommissioned per the WAC.

B. Ownership

This project will provide sanitation facilities to a private home owned by a member of the sponsor Tribe, Snoqualmie. Upon completion, the facilities will be transferred to the homeowner. The system will be operated by the homeowner.

C. TERO & Other Fees

TERO fees do not apply.
