Sheridan 4MG Water Tank

This four-million-gallon concrete water tank had structural issues from the time of its construction. DOWL first prepared a Preliminary Engineering Report (PER) that assessed the condition of the tank and prepared options for rehabilitation or total reconstruction. The city selected rehabilitation so the PER was submitted to the Wyoming Water Development Commission and State Revolving Funds Program and the $3 million in funding was obtained. A post-tensioned structural design of the new roof was selected and concrete baffles and re-enforced columns were included. DOWL also provided assistance on how to operate the water system when this tank is not operational, as it is the most important tank on this system. Extensive quality control measures were used in the design, in the selection of the contractor, and in construction. The new roof involved a 700-CY monolithic pour that required extensive planning to make sure that it was placed within the allowable timeframe. The project is constructed and was completed under budget.
