Widefield Terminal Tank Rehabilitation

Matrix assessed the 2.29-million-gallon Widefield Terminal Tank for the Fountain Valley Authority (FVA) in Fountain, Colorado. The FVA was not aware of the tank’s maintenance history, and many believed it had only had minor maintenance performed since it was constructed in 1981. The assessment included evaluating the structural integrity of the tank and confirming code as well as health and safety compliance. The tank is essential to Fountain Water’s ability to meet demand and could only be taken out of service for a limited time between October and April. Due to this restriction, the Matrix Team performed a floating assessment of the roof components while the tank was in operation. This allowed a detailed assessment of critical structural components while the FVA continued to supply water to its customers.

The assessment confirmed that the tank needed repairs for long-term reliability and stability. Matrix and the FVA agreed that all critical maintenance that affected water quality and structural stability had to be performed. The primary Scope of Work consisted of replacing steel rafters and recoating the interior and exterior of the tank. Additional elements included installing a handrail around the outside of the tank, replacing the center vent, installing a new access roof hatch, and installing additional roof vents to promote better circulation. We worked with the contractor to expedite design and review of the necessary rafter replacements to keep the project on schedule. Our team also provided construction support, including daily construction observation, responding to Requests for Information (RFIs) and submittals, and preparing record drawings at the conclusion of construction.
