The primary aspects of stormwater management are the treatment, storage, and controlled release of stormwater runoff from new construction and redevelopment projects. The critical elements of any stormwater management system design are Best Management Practices (BMPs) and Low Impact Development (LID) techniques such as deep sump and hooded catch basins, vegetated swales, and bio-filtration basins which reduce pollutants prior to storage and controlled stormwater release. We recognize that each project is unique due to location, physical constraints, and work proposed albeit stormwater regulations, policies, and guidelines can be com plex and evolving. Our clients include homeowners, land developers, and municipal and state agencies.

We not only recognize these realities and challenges, but are well equipped to deal with them successfully; our personnel have a great amount of diverse experiences in designing stormwater management systems that meet the requirements of federal, state, and local laws and regulations as well as our clients’ particular needs.  Our awareness and our expertise born of training and experience make us fully capable of completing projects in ways that fulfill our clients’ goals while also protecting the local environment.  

We provide our clients with comprehensive stormwater management system designs, including system operation and maintenance procedures to sustain the stormwater management after construction.  Altogether, these services will minimize or eliminate downstream flooding impacts due to development activities, delivering to each client a stormwater management system whose quality meets or exceeds the regulatory standards.

Sanitary Sewer

GM2 has planned and designed wastewater collection and treatment solutions, including gravity sewer design, small-scale onsite wastewater collection and treatment (less than 10,000 GPD), sewer pump stations, and innovative alternative treatment systems.  Our clients for these kinds of work have ranged from individual homeowners to residential and commercial developers. 

Our clear understanding of local, state, and federal laws and regulations governing sewage collection and disposal allows us to accurately evaluate and advise our clients on the most fitting options available to meet their project requirements.  Whether your project entails construction of a single house or a major rehabilitation project, GM2 can give a sanitary sewer plan that will be not only effective in accomplishing its purpose, but cost-effective as well.
