Hatch Mott MacDonald recognizes the importance of reliable community wastewater infrastructure. It promotes economic development, protects public health and environmental quality, and is essential in today’s competition for jobs.
Throughout HMM’s more than 70 years, our pipeline specialists have created cost-effective, sustainable infrastructure. Our engineering solutions optimize the hydraulic performance and the pipeline life through sophisticated life cycle cost analyses.
Our engineers recognize the importance of selecting the most effective pipeline construction method for the routing situation. Whether it’s a 6-10 ft diameter trunk sewer or a nominal 6-18 in diameter lateral sewer, HMM strives to minimize utility conflicts and optimize constructability. When appropriate to minimize surface impacts—such as a city street or a environmentally sensitive area—HMM’s nationally recognized specialists in trenchless technologies, from micro-tunneling to pipe bursting, provide the critical assessment, design, and construction management that’s needed. Please refer to HMM’S Tunnel Practice for more information on the firm’s tunnel specialties.
Our expertise doesn’t stop there. We also utilize the newest proven pipeline rehabilitation methods to address existing pipes, particularly those constructed of brick or prestressed concrete cylinder pipe. These services have been critically important to reduce sewer system infiltration which occupy needed capacity, or cause sewer system overflows.
Whatever your needs in sewer or drainage pipelines, HMM delivers solutions.
