Project Overview

The City of Montrose currently owns a 3.0 million gallon below-grade storage tank situated on Sunset Mesa approximately 500 feet east of the baseball field complex as shown in the tank location drawing. This tank was originally built around 1960. A formal condition assessment performed for the existing tank in 2014 determined that portions of the tank are structurally compromised and in need of $1 to $2 million in repairs. The tank has also experienced pressure and operational issues due to its relatively low nature and due to an increase in water demands over the years. As a result of the tank’s present condition, the existing tank is currently isolated from the City’s water distribution system and is only being used to store water for use in irrigation of the Sunset Mesa sports fields.  

In September of 2018, the City hired Farnsworth Group to perform a detailed evaluation of tank alternatives and prepare construction plans for the replacement of this aging tank. Through this process, the City selected the preferred and most economical tank alternative as twin 1.5 million gallon standpipe tanks, approximately 130 feet tall.  This project will construct the first of these two tanks with its associated piping and booster pump station. The tank will be situated immediately north of the existing tank (see drawing) which will remain in service until the end of new tank construction.
