Agenda 07/09/2019 Item #16C10 (RFQ #15-6469-5 w/Wells & Water System, Inc.)07/09/2019
EXECUTIVE SUMMARY
Recommendation to approve a $397,608 work order under Request for Quotation No. 15 -6469-5 to
Wells & Water System, Inc., under Project Number 70085, to condition and treat twelve
production wells in the Golden Gate Wellfield.
OBJECTIVE: To complete well rehabilitation by performing well conditioning and treatment
(acidification) of existing Tamiami wells in the Collier County Water Sewer District Golden Gate
Wellfield.
CONSIDERATIONS: The proposed scope of work under Project No. 70085, Request for Quotation No.
15-6469-5, is consistent with the FY2019 Budget approved by the Board of County Commissioners on
September 20, 2018.
The proposed project consists of injecting an acid solution into selected Tamiami production wells to
provide well bore rehabilitation and well yield improvements. The acid solution dissolves existing
mineral deposits within the well, thereby improving well pumping efficiencies, reducing drawdowns, and
providing for higher water production rates.
The proposed well treatment (acidification) will provide needed rehabilitation of the existing wells,
thereby increasing the water pumping rate from each well to the North County Regional Water Treatment
Plant and South County Regional Water Treatment Plant. Completing this well rehabilitation will extend
the useful life of these existing wells in lieu of constructing new wells.
The County issued Request for Quotation No. 15-6469-5, “Acidification of Twelve Production Wells -
Phase 3,” on May 13, 2019 and distributed it to all vendors on the County’s Fixed-Term Well Testing,
Drilling, and Maintenance Contract No. 15-6469. Of the five vendors notified, one submitted a quote by
the May 22, 2019 deadline as summarized in the below table.
VENDOR QUOTE
Wells & Water Systems, Inc. $397,608
No quotes were received from All Webbs Enterprises, Inc., Layne Christensen Company, Naples Well
Drilling, Inc., or Youngquist Brothers, Inc.
This project is the third phase of a multi-phased project to complete all the well treatment rehabilitation
work on the Tamiami Wells. The first phase received three quotes, Wells & Water, All Webbs
Enterprises, and Layne Christensen Company, from the County’s Fixed-Term Well Testing, Drilling and
Maintenance Contract No. 15-6469. Wells & Water was the lowest responsible vendor. The second
phase received two quotes, Wells & Water and All Webbs Enterprises. Wells & Water was the lowest
responsible vendor.
This work is specialized and not every Contractor included in Contract No. 15 -6469 is interested in this
specific type of well treatment rehabilitation project. Wells & Water have done an outstanding job
working with staff to complete the previous well rehabilitation projects under budget and on -time;
therefore, it would be difficult for others to compete. Further, the bid received from Wells & Water is
much lower than the engineer’s estimate.

Based on the history of this multi-phased project, County staff is acceptable with only receiving one quote
and recommending award to Wells & Water to complete Request for Quotation No. 15-6469-5.
The quote specifications informed the respondents there may be unforeseen conditions associated with the
project. The quote amount incorporates an owner-directed allowance of $20,000 for work related to
unforeseen conditions including, but not limited to, conflicts with existing facilities not reflected in record
drawings and modifications or repairs resulting from unforeseen utility work associated with this project.
The price for any needed additional work will be negotiated prior to commencement in accordance with
the County’s Procurement Ordinance and the terms of the agreement.
County staff determined the bid to be fair and reasonable and recommends awarding the project to Wells
& Water Systems, Inc. The bid received was approximately 42 percent less than the engineer’s cost
opinion. In its June 6, 2019 recommendation letter, the design professional, Agnoli, Barber & Brundage,
Inc., recommends awarding the project to Wells & Water Systems, Inc., who has a satisfactory
performance and warranty record on previous, similar, utility-related projects.
FISCAL IMPACT: The source of funding is Water User Fees, Fund (412). The project is expected to
be completed in 2019.
LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires
majority vote for Board approval. -SRT
GROWTH MANAGEMENT IMPACT: This project meets current Growth Management Plan
standards to ensure the adequacy and availability of viable public facilities and to remain in compliance
with all regulatory programs.
RECOMMENDATION: To approve a $397,608 Work Order under Request for Quotation No. 15-
6469-5 to Wells & Water Systems, Inc., and authorize the Chairman to sign the attached Work Order.

Re: Award Recommendation
RFQ 15-6469-5, Acidification of Twelve Production Wells in Golden Gate Wellfield
Dear Mr. Sivert:
We have reviewed the bid for RFQ 15-6469-5 for Acidification of Twelve Production Wells in the
Golden Gate Wellfield. The apparent low bidder is Wells & Water Systems of Fort Myers,
Florida. The bid appears to be complete and consistent with the intent of the technical
specifications and was approximately 42% below the Engineer’s Opinion of Probable Cost. Wells
& Water Systems is a qualified firm to conduct the requested work and has conducted similar work
for the County in the past with excellent performance reviews. We recommend that Wells & Water
Systems be awarded the contract for RFQ 15-6469-5.
Sincerely,
AGNOLI, BARBER & BRUNDAGE, INC.
