Magney Construction, Inc. is a Minnesota-based general contractor headquartered in Chanhassen. Since 1994, nearly 100% of our work has focused on municipal water and wastewater treatment facilities. We understand not only how to construct these facilities, but how to keep them running safely and in compliance while improvements are underway.
We self-perform earthwork, site utilities, concrete, masonry, carpentry, process piping, and process equipment installation — giving our clients better schedule control, quality, and cost certainty.
Early collaboration on cost estimating, constructability reviews, value engineering, and phasing — so your project starts with a reliable budget and schedule.
Traditional design-bid-build delivery backed by three decades of treatment plant experience and a deep regional subcontractor network.
A single team from planning through startup, incorporating value engineering to maximize cost-effectiveness and functionality.
Equipment replacements, rehabilitation, and targeted facility improvements inside active treatment plants.
New 10.0 MGD water treatment facility including six gravity filters with anthracite and greensand, a 1.2-million-gallon concrete reservoir, a 200,000-gallon clearwell, flow-paced chemical feed systems, plate settlers, and all process piping, valves, pumps, and equipment. Roughly 50–55 subcontractors worked under Magney’s direct supervision.
Nearly one mile of site piping from 3” to 72” diameter, thousands of feet of interior process piping, valves, process equipment, cast-in-place concrete, and four new 130-foot-diameter solids contact clarifiers — helping SPRWS maximize water production to 112.0 MGD.
New filter in the operations building, chlorine contact chamber, new secondary clarifier control structure, replacement of primary clarifier and filter feed pumps, replacement of aeration blowers and equipment, and renovations of the existing control, aluminum, and blower buildings.
Our goal on every project is zero incidents and zero lost-time accidents. Magney’s Experience Modification Rate has remained well below the industry average of 1.00 for five straight years.
Whether you are planning a new treatment facility, an expansion, or improvements within an active plant, our team is ready to help you deliver it safely and successfully.
