Zone 4 South of the City's water distribution system serves the Briarwood area.  It is greatly deficient in the amount of water storage needed to meet peak usage and fire flow demands.  To alleviate this problem, W.O. 14-09 includes the construction of a new 750,000 gallon prestressed concrete water reservoir; all associated piping, valves, and site work; and demolition and removal of the existing 186,000 gallon tank.  The project includes provisions for an aeration mixing system in the new reservoir to help reduce issues with water age and disinfection by-products; instrumentation control modifications; and electrical modifications.  Due to a very limited area for the tank site, the existing tank will be taken off-line and removed before starting construction of the new tank, and a temporary tank and piping system will be placed into service. 

The project was advertised March 12 thru March 26 in the Billings Times and on the City's website. Bids were opened March 31, 2015 and there were two bidders.  Western Municipal submitted the apparent low bid.  Staff requests that the City Council award a contract based on those bids.

The Council may: 

• Award a construction contract to Western Municipal Construction in the amount of $3,043,112.00; or
• Reject all bids, which will delay the project and the ability to provide needed water storage.
