Well 119 Maintenance & Rehabilitation

The City of Aurora is seeking qualified well equipment and maintenance contractors to provide all labor, materials, transportation, tools, supplies, equipment, and appurtenances necessary to complete the satisfactory rehabilitation of existing Well 119 for the Water Production Division.

The existing Well 119 was originally constructed in 1989 and completed in drift formations and is gravel packed. The well consists of 12-inch casing (pitless adapter), 20-inch casing extending from approximately 7 feet to 80 feet below ground surface, and is screened from 80 feet to a total depth of 130 feet.

The primary purpose and intent of this project is formation redevelopment, combined with inspection and repair of all related well equipment, including electrical cables, motor, and column piping.

Over-pumping of the formation with the existing pump has been a long-standing operational issue and is currently mitigated through throttling of the discharge line valve. A replacement pump will be furnished by the City for installation under this contract. The pump is a Byron Jackson Model 10MQH, 3-stage, full-diameter submersible pump.
