Mulvane Design-Build Wastewater Treatment Plant

Location: Mulvane, Kan.

Client: Mulvane, Kan.

Completion Date: 2006

In response to a compliance order issued by the Kansas Department of Health & Environment, Burns & McDonnell was retained to provide planning services for the City of Mulvane, Kan. The order provided for evaluating alternatives to correct deficiencies at an existing wastewater treatment facility, provide for growth and meet new requirements for biological nutrient removal.

Working in concert with city staff, elected officials, financial planners and public representatives, it was concluded that a new facility was the most economically attractive alternative to meet the city’s long-term objectives.

In July 2005, Burns & McDonnell was selected to provide a turnkey facility, including design, construction and startup. The design team, consisting of Burns & McDonnell, city operations and engineering staff, contractors and equipment suppliers, collaborated to evaluate alternatives, select unit processes, prepare detailed design and prepare a guaranteed maximum cost for design and construction. All pricing elements were validated through a competitive quotation process. Subsurface conditions were evaluated and the site was relocated to avoid dewatering and shoring of excavations that resulted in a net savings to the city of nearly $1 million. By October 2005, construction of the new facility was under way.
