Clean Waters, Clean Environment  

At H2M, our wastewater engineers recognize that no two projects are exactly alike. We understand that two pump stations with the same capacities and specifications can pose unique challenges in their design, construction, operation, and maintenance.  Using cutting-edge solutions, detailed construction drawings, and comprehensive internal quality control practices, H2M delivers design excellence on time and on budget.

With the treatment facility’s long-term operation in mind, we walk through each design to anticipate problems.  You can rely on our firm to provide sustainable treatment solutions that reduce environmental impacts, promote business growth, and improve the community’s quality of life.

H2M’s team of seasoned professionals continue to develop pioneering solutions that reduce the cost of wastewater infrastructure projects. Reuse, nitrogen removal, wetlands preservation, new systems or renovations of old systems, H2M’s wastewater team has a solution to the challenges each client faces.
