Approval of the On-Call Professional Services Contract with Carollo Engineers, Inc. ("Carollo") for Construction Administration & Inspection Services will provide the project administration and inspection requirements necessary for a successful project delivery of the Fort Tuthill Well #2 and Pumphouse reconditioning project; expected to last 15 months in duration. 

This scope of engineering services includes the production of Bid Phase documents necessary for project advertisement, management of Pre-Bid meetings, reviewing contractor bids for completeness, producing and administering the construction schedule, reviewing submittals, producing project documents, providing construction inspections, performing materials testing, producing as-built plans, manage start up and commissioning activities, and managing electrical engineering sub consultant. 

There is a master On-Call Professional Services Contract with Carollo approved by the City Council and under the City's Procurement Code, requests to contract for On-Call Professional Services over $100,000.00 require that staff seek approval from the Change Order Committee prior to seeking Council's approval. The Change Order Committee granted final approval of this On-Call Professional Services Contract on 4-21-2026. Staff, now, seeks City Council approval for this vital water production infrastructure project to help meet growing water demand.

No Policy Impact

In 2018, the City contracted with Atlas Corporation for well siting services and one of the locations that looked promising was the Coconino County Fort Tuthill Recreation Area.  The City had previously drilled a well at Fort Tuthill in 2007 and under an agreement with Coconino County we maintained the right to drill one more additional well on the campus if we chose to do so. Atlas Corporation located a site on an unused section of the park and the City hired Boart Longyear through a qualifications-based selection process.  Boart-Longyear drilled our new well down to 2,500 feet in just 100 days and de-mobilized on June 10, 2021. 

On June 2, 2021, City Council and Staff were invited to the well site for a celebration and barbeque. In 2022, the City hired Carollo Engineers to generate a Conceptual Design Report and develop a workshop to guide our decision process on the construction of a new pumphouse for this new water source. The decision was made by Staff to retrofit and re-tool the existing pumphouse, Fort Tuthill Well #1 pumphouse, to now also receive this second new water source from Tuthill Well #2. Carollo produced a plan set to squeeze additional infrastructure into the existing pumphouse and at the same time, replace some of the existing infrastructure that limited the water production from well #1. 

Additional infrastructure for this project will include items such as 2,600 feet of 8" raw waterline connecting the new well to the pumphouse, a new chlorine disinfection system, a new 30,000-gallon disinfection contact tank, new filtration equipment, and new booster pump to boost the finished water up to distribution pressures. This design also addresses the previous designs shortcomings that ultimately restricted well #1's water production by about 1/3. The new pumphouse design, and the addition of the new well #2 will produce approximately 1,440,000 gallons of water per day for the City's residents and visitors.

Safe & Healthy Community: Foster a safe, secure, and healthy community. 

Goal PF.2.: Provide sustainable and equitable public facilities, services, and infrastructure systems in an efficient and effective manner to serve all population areas and demographics.
Goal WR.3: Satisfy current and future human water demands and the needs of the natural environment through sustainable and renewable water resources and strategic conservation measure.
Goal WR.4. Logically enhance and extend the City's public water, wastewater, and reclaimed water services including their treatment, distribution, and collection systems in both urbanized and newly developed areas of the City to provide an efficient delivery of services.
Goal WR.6: Protect, preserve, and improve the quality of surface water, groundwater, and reclaimed water in the region.
Goal CD.1. Improve the City and County financial systems to provide for needed infrastructure development and rehabilitation, including maintenance and enhancement of existing infrastructure.

This project will ultimately increase our water production capabilities which will increase our ability to serve additional residents.

This project will add to our water production capabilities and grow our infrastructure to continue to meet planned water demand. Additional water production infrastructure increases our production portfolio giving us more redundancy and resiliency moving forward as we continue to grow as a City.
