Lyman Tank and Transmission Main Construction - W88 - City of Bozeman

Construct a new 5MG storage tank at Lyman, decommission existing Lyman storage tank, Condition Assessment-based repairs of the existing Lyman transmission main, new supply main tie in to new storage tank, new transmission main tie in from new storage tank to existing transmission main, new chlorination/fluoridation feed facility. Decommission Pear Street Booster Station if Hydraulic Grade Line of tank raised to meet Sourdough Tank. The Lyman water supply is a critical element of the city's overall water supply portfolio accounting for roughly 20% of annual supply volume to the city currently. The source provides supply redundancy and resiliency as it is geographically removed from the Sourdough/Hyalite source and provides an independent connection to the distribution system. The effective available water supply is increased since the new storage system will not leak and will expand the number of customers able to be supplied by Lyman water. Likelihood of failure of Lyman supply system will be dramatically reduced by replaced storage. It will also complete new transmission and Condition Assessment-based rehab to existing transmission. The project is included in the city's 2023-2027 Capital Improvement Program (CIP). As of September 13, 2022, further details regarding design and construction have not been identified.* *Project information has been obtained through a public capital improvement plan (CIP).
