Water/Wastewater

Flatiron is a recognized leader in the construction of conventional water and wastewater treatment facilities along with membrane and reverse osmosis technology. We help clients deliver water to their communities by employing unique techniques for renovations, upgrades to existing facilities, and construction of new water and wastewater treatment plants.

Because we self-perform much of the concrete, piping and mechanical work, we can better control quality, cost and schedule, passing those benefits on to our clients. Flatiron works under a variety of different contracting methods including design-build, finance, operate and maintain.

Flatiron combines our own experience with that of parent company, HOCHTIEF and sister companies, E.E. Cruz, Turner and Leighton to offer clients a full range of water/wastewater services.
