Title
Resolution Approving a Construction Contract with Applied Ingenuity, LLC for the 2023-2024 Denver Basin Aquifer Rehabilitation and Pumping Equipment Replacement Project [Seven wells within Red Hawk, Woodlands, Castle Oaks and Bell Mountain Ranch subdivisions]
Body
________________________________________________________________________________
Executive Summary
The purpose of the resolution (see Attachment A) is to request Town Council approval of a Construction Contract (see Exhibit 1) with Applied Ingenuity, LLC (Applied) for the 2023/2024 Denver Basin Wells Rehabilitation and Pumping Equipment Replacement Project. In 2016, Castle Rock Water started a planned well rehabilitation program. This program is designed to help maintain water production yields from our current deep well assets and to reduce the likelihood of emergency well failures. The program targets wells that are showing declines in well yield and/or have been identified as equipped with older pumping equipment. This program has proven successful over the past few years due to limited well failures during peak demand season, increased well efficiencies, decreased power consumption, and increases in well yield. The 2022 rehab project included seven wells and contributed to an increase in well efficiency of 7% over the past year, as shown below.

In fall 2023 through spring 2024, CRW is targeting four Denver Basin wells for planned rehabilitation and equipment replacement with Applied. Attachment B shows the locations of the wells that will be rehabilitated. Additionally, the contract will include a video investigation of three Bell Mountain Ranch Wells, BMR A-1, BMR D-1, and BMR Da-1, that CRW would like to potentially tie in to the newly acquired Bell Mountain Treatment Plant, as these wells are currently piped to discharge directly into East Plum Creek and subsequently capture that water downstream at CR-1 Diversion. CRW recommends approval of a construction contract with Applied in the amount of $874,353.00 plus a ten percent Town-managed contingency in the amount of $87,435.30 for a total project cost with Applied of $961,788.30. The schedule is critical for this project given the need for these wells during irrigation season. Work will begin immediately upon contract approval and is scheduled for substantial completion by April 17, 2024.
