Design-Build Wastewater Treatment Project to Handle New Development

The city of Mulvane, Kan., recently awarded the joint venture team Burns & McDonnell/CAS, LLC a contract to design and build Phase I of the Mulvane wastewater treatment plant improvements. Following a series of studies performed by Burns & McDonnell in spring 2011, the city gained funding to construct facilities to handle wastewater flow from a new casino development. This phase of improvements includes primary treatment — screening, grit and grease removal, and equalization — of the casino development flow; expanded aeration capacity; a selector basin for improved biological nitrogen removal; and chemical feed facilities along the pipeline route. Phase 1 was scheduled to be completed by mid-December 2011.
